The beginning of HVAC is not clear, though as early as second century, a lot of Roman cities were using a central heating system known as hypocaust. This is further popularized during the Industrial Revolution as big factories used it. Now most modern buildings that you see have integrated HVAC.

The HVAC system is also known as climate control. This is because these three functions are essential in maintaining comfort in every dwelling.

The primary use of HVAC is to regulate room temperature, humidity, and air flow, ensuring that such elements remain within their acceptable ranges. Effective control of such factors minimizes health-related risks. A very humid atmosphere impairs the body’s ability to regulate body temperature as it prevents the evaporation of sweat. High humidity also decreases physical strength, which usually leads to fatigue. An unhealthy surrounding can also affect people’s thinking abilities. Hypothermia, heat stroke, and hyperpyrexia, among others, are some of the illnesses that may also occur.

Three Functions of HVAC
Heating is significant in maintaining adequate room temperature especially during colder weather conditions. There are two classifications of heating: local and central. The latter is more commonly used because it is more economical. Furnace or boiler, heat pump, and radiator make up the heating system.

Ventilation, on the other hand, is associated with air movement. There are many types of ventilation, but they all function similarly. Ventilation is necessary to allow carbon dioxide to go out and oxygen to get in, making sure that people are inhaling fresh air. Stagnant air causes the spreading of sickness, usually airborne, and allergies. But it is also essential to maintain an efficient ventilation system, especially in the attics. Insufficient ventilation usually promotes the growth of bacteria and fungi such as molds because of high humidity. It will also decrease the effectiveness of rafter and roof sheathing insulation because of water vapor condensation.

The air-conditioning system controls the heat as well as ventilation. They often come in different sizes. Most air conditioners have large air ducts, so it is better to check out the building first to see if they can be installed. Or else, you can use the split system or remote coils. It is necessary, though, that air ducts are properly cleaned. Pathogens thrive in dirty air ducts. Return-air grills are also vulnerable to chemical, microbiological, and radiological elements. Thus, HVAC return-air grill height should be that it is not accessible but visible for any observation.

The Future of HVAC
How has technology changed in the HVAC field? Well, using PLCs (programmable logic controllers) in HVAC is the trend nowadays. But a great deal of development of the HVAC system lies on the ever-changing technology and continuous innovation. Companies are adopting wireless technology after they found out that networking HVAC controllers, which often use sensors, can eventually cut installation and labor costs. A lot of engineers are also focused on further improving this technology through the use of mesh wireless setup, which will work for both the wireless sensor and wireless controller networks.  The only downside of this could probably be the risk of being exposed to RF (radio frequency) radiation.

The installation of an HVAC system is imperative if we want to achieve maximum comfort and be healthy in our homes, office spaces, or other building facilities. But you also need to consider the building size in installing an HVAC system. Optimum efficiency and comfort level are best achieved if the system is appropriate for the size. After all, any ineffective system usually means more incurred costs in the future. You should also see to it that HVAC is carefully integrated to the overall building design so other aspects needed for proper operations, such as cabling, are not sacrificed.

Every Trane air conditioner, beginning with Reuben Trane’s patented invention, is long-lasting because of their carefully chosen, tested materials. But more than their durability, Trane air conditioners are known for their reliability, excellent performance, and efficiency. Ultimately, they are products of mechanical and electrical geniuses who work to produce the best-quality Trane air-conditioning system.

Trane in Your Homes
Potential buyers should know that all residential air conditioners are capable of providing the best kind of comfort any individual needs. But the most impressive among Trane air conditioners is Trane XL19i. This air conditioner helps homes cope up with the drastic weather changes through its two compressors (one is used during temperate weather while the large one is used during hot days). Economically, it has lower cooling costs compared to other air conditioners available in the market today because of its very high energy efficiency rating of 19.5.

To further maximize its efficiency and performance, every Trane air conditioner possesses other added features. One of these special add-ons is called Comfort-R. This add-on decreases temperature variances by working two ways. It enhances airflow and effectively controls humidity in cooling and produces warmer air during start-up of XL19i Weathertron Heat Pump. With all its benefits and significant features, it’s practically no wonder why Trane’s XL19i won Best Buy in the Premium Category of Consumers’ Digest.

But if these aren’t enough, wait till you learn that aside from these great attributes, you can also take advantage of a 10-year limited warranty in their air-conditioning parts, which can be extended. All you need to do is ask a salesperson upon purchase.

In order to maintain clean air, Trane advises the addition of Trane Air Cleaner to filter all pollutants and irritants.

But if you are already using Trane air conditioners, you can take note of some tips to maintain their good condition:

·    Clean or replace filters monthly.
·    Maintain its brand-new appearance by cleaning its enamel finish with soap and water. Do not use any synthetic solvents.
·    Periodically check and clean condensate drains.
·    For any assistance, don’t hesitate to call Trane technicians.
One piece of advice: always ask a Trane dealer to properly calculate load. Or else, you might encounter maintenance problems later.

Fundamentals of SWACS
Cold seawater can be taken from the bottom of the ocean or from the lakes. Other specific places like Hawaii and Fort Lauderdale and Miami in Florida are also favorable spots.

SWACS makes use of the following main components: a heat exchanger, freshwater distribution system, and seawater supply system. For maximum efficiency, you can adjust these three factors to suit the climate, location, and type of facility this system is installed. Cold water is pumped deep either from the ocean or from the lake. It then passes through a heat exchanger, which is usually contained in a cooling station. It is now the heat exchanger’s job to transfer heat from the freshwater distribution loop to produce cold water, which will be later distributed all throughout the building for air-conditioning.

Sometimes it is economical and practical to use auxiliary chillers. To supply deep cold seawater to maintain minimum temperature is, more often than not, impossible or remote. First, seawater cools the chilled freshwater using a heat exchanger; then an auxiliary chiller is used to secondarily cool it. As long as the coolness of the condenser is maintained, it can work efficiently.

Benefits of Seawater Air-conditioning
SWACS functions similarly to a conventional air-conditioning system. However, if it comes to economic savings and environmental friendliness, SWACS is a better choice.

SWACS can help you save approximately 90 percent of energy used. In most companies, air-conditioning cost is quite huge, approximately two-thirds of which is for chillers’ and cooling towers’ operations. SWACS’s chillers last longer than that of a conventional air-conditioning system. Moreover, it hardly depends on any future price changes of energy. But it should be noted that though this system has low operating cost, it has a high capital cost.

The use of SWACS also minimizes pollution and greenhouse effect.  This system doesn’t depend on fossil fuels, reducing air pollution and acid rain. It also prevents greenhouse effect since it uses a simple heat exchanger instead of a CFC-producing chiller machinery. CFCs (chlorofluorocarbons) cause the continuous depletion of our ozone layer.

Viability of SWACS
Site location is one of the major factors that determine the overall viability of SWACS. Others are the following:
·    Air-conditioning load size
·    Utilization of the air-conditioning system
·    Electrical costs
·    Onshore distribution system
·    Distance offshore to cold water

SWACS is one of the most vital energy source alternatives because of its economic and environmental benefits. Though the system is not altogether perfect, it has potential in helping us curb the continuing rise of energy prices. What’s more, we can keep our own planet Earth clean, free, and safe for all of us to live in.

A lot of homes and commercial and industrial facilities are using portable air conditioners for three basic reasons. They cool efficiently; they cost less to operate and very convenient. You practically don’t need to turn on your central air-conditioning system to cool only one room. Its 30-inch height and 80-pound weight makes it convenient for an individual to move or drag  (as there are some models with built-in wheels) this self-contained unit and make it stand on the floor. You don’t need to bore holes on your walls as they don’t need to be mounted or physically installed. Lastly, it takes up little space in your room.

Therefore, if convenience and simplicity are your main goals for your air-conditioning system, then portable air conditioners might be for you. But you have to also take note that they cost slightly higher than conventional window air conditioner. To add to that, portable air conditioners are loud—noisy—compared to central or minisplit air-conditioning systems. If this is going to be a problem but you still insist on using one, you can search for reviews or feedbacks of several other kinds of units and choose one that produces the least noise. You may try using Airtemp air conditioners, which are so quiet and hence are perfect for light sleepers.

Portable air conditioners are much more ideal in homes or apartments. But they can also be used in larger enclosed areas. Their cooling capacity, however, depends on their size. Generally, the bigger the unit is, the higher the efficiency is and the larger area they cover. The standard criterion for an effective portable A/C unit is 10,000 BTU at 500 square feet. You have to remember one significant point, though. Typically, larger portable air conditioners require more energy.

In purchasing portable air conditioners, there are two things you must consider: its cooling capability and energy efficiency rate. The best portable air conditioners have about 12,000 BTU and 12 EER or higher. Higher efficiency ratings usually mean lesser energy consumption and thus lower power consumption. Using Ace air conditioners, for example, can basically cut down your electrical costs to 12 percent because of its high efficiency rating. You also try to select those units with energy star. Energy star represents that the unit has met the guidelines of U.S. Department of Energy’s EPA (Environmental Protection Agency), thus ensuring that they are environment friendly.

Shopping for portable air conditioners is relatively easy and convenient. If you aren’t really sure what unit to buy, you can search for online reviews and consumer feedbacks. This way, you will have an idea which of these work for a number of people. You may also ask some of your friends, colleagues, or relatives. Definitely, there are different appliance stores nearest you that sell these kinds of units. You may inquire from their respective salespersons or technicians. You may also buy online. There are a lot of Web sites that offer different HVAC products, including portable air conditioners, which are just as affordable as those found in stores. A lot of these portable air conditioners are manufactured and sold by trusted and world-renowned companies such as Trane, Carrier, Goodman, and Sanyo, among others.

The most popular HVAC equipment used in homes and commercial and industrial buildings are heat pumps, chillers, and unitary and packaged terminal air conditioners. Heat pumps cause heat to move from a lower to a higher temperature reservoir through mechanical means. Vortex tubes, phase-change heat pumps, gas-compression heat pumps, and geothermal-exchange heat pumps are some of the typical kinds. Performance of heat pumps is best compared through their coefficient of performance (COP). This is the term used to explain the relationship between heat output and electrical power utilized. COP of most heat pumps are continuously rising, almost as high as 5.

Thus, they become a well-liked choice for home heating. Chillers are machines that chill water, which then cools and dehumidifies air. They require low electrical power and are typically powered by gas turbines. Steam is often used in absorption chillers. Reciprocating, screw-driven, and centrifugal chillers are the basic varieties. Unitary air conditioners are sold either as a single package or a split system. Units with high efficiency perform similarly with conventional efficiency air models but use less electricity. Packaged terminal air conditioners, meanwhile, include outdoor louvers and heating availability, among others. They are usually mounted on the walls. Another well-liked equipment is fiber glass ducts. These ducts can absorb nice unlike sheet metal air ducts.

These—as well as other HVAC equipment such as boilers or furnaces, exhaust fans, and coils—are available from different manufacturing companies found anywhere around the world. One of them is Lennox. Lennox air-conditioning systems are known for regulating and maintaining indoor air quality. They also distribute refrigeration systems globally. These are primarily used for the preservation of food in restaurants, supermarkets, and warehouses, among others. Another would be Ruud. For over 100 years, they have been servicing residential and commercial facilities with quality HVAC products.
You can also purchase HVAC equipment online. Ebuild.com has one of the most extensive interactive catalogs of HVAC equipment for contractors, builders, and owners alike. If you’re looking for air conditioners, for instance, you can actually browse among 340 products and choose your most desired unit through manufacturer and brand preference, nominal tons, refrigerant type, SEER, and energy star compliance. This refined-search method will produce results that will likely suit your style and your needs.

If you wish to purchase HVAC equipment from specific companies, you may refer to Apple Directory and to HVACportal.com. Apple Directory contains a comprehensive alphabetical listing of HVAC equipment and their corresponding manufacturer and seller in the United Kingdom. These are major U.K. firms that have proven track record when it comes to good-quality HVAC equipment. HVACportal.com , meanwhile, is helpful when you have the definite equipment in mind since the site showcases companies and their main products. For example, if you want to buy a gas-fired boiler, fluid-to-fluid exchanger, or water heater, you may visit Aerco.com.

For cost-cutting measures, it is advisable that you procure an HVAC equipment without a middleman. Usually, most price quotations from contractors are already marked up to compensate with the other costs they incur in running the business.  The problem lies when you aren’t sure what equipment to buy, much more its specifications. You may then resort to bidding. Get the most competitive estimates from different contractors, choose the most ideal, and have them buy and install the equipment.

You can also contribute to environment preservation by selecting the most efficient HVAC equipment. They use lesser energy and decrease pollution due to onsite combustion. Furthermore, they last longer. There are limited air-conditioning systems available today that are CFC free. Thus, you prevent the continuous deterioration of our ozone layers.

Conducting a vacuum test goes beyond to simply adhering to the rules set by NADCA. Usually, a lot of debris and dust remain after construction work. If these are not detected and left to accumulate, the HVAC system’s functions will be impaired and render the whole system ineffective. For sure, the desired comfort level will not be reached. Therefore, vacuum testing is a specific, scientific procedure performed to establish cleanliness of the HVAC system, especially for checking out debris. However, the term “debris” doesn’t include any hazardous material, such as asbestos, lead, or VOCs (volatile organic compounds).

If you are dubious as to the cleanliness of a specific area, you may administer the test only on that location. The standard states that the amount of dust and debris should be 1 milligram per 100 cm2 or less. But since NADCA’s Standard 1992-01 is not applicable to HVAC materials that are porous, vacuum testing may not work on concrete or drywall. It may also be useless for solid fiber glass HVAC duct. As to what testing may be administered to them, NADCA is still in the stage of developing it.

You may wonder, how is vacuum testing performed? NADCA has developed these following steps in conducting vacuum testing:

- First, vacuum testing uses a model with cut slots. These openings are attached to a nonporous surface or to the area that is subject to testing.
- Next, a vacuum collection device is passed over the openings and operates continuously all throughout the cleaning. An air pump pulls through any air found inside the HVAC component.
- Dust and debris are then removed from the surface of the HVAC system and deposited on the vacuum cassette.

Yet no matter how standard vacuum testing is, it is still not the most effective method to use in detecting leaks because it introduces air and induces moisture into the system. As you may already know, molds and other microbes thrive and exist in damp, moist places. Furthermore, the vacuum prohibits the technician from establishing where the leak is; he will only learn that there is indeed a leak. Worse, the vacuum will eventually hide the leak. For a specific illustration, you can download it and check its vivid description about flux buildup in a solder connection.

NADCA guidelines also specify utilizing HEPA filters for all vacuum devices that are exhausting air contained inside the facility. Moreover, any vacuum device that is draining air outside the building needs a particulate collection instrument as well as adequate filters to hold debris taken from the HVAC system. These devices should not allow the reentry of these pollutants to the establishment. The releasing of debris, on the other hand, should follow the strict procedures, regulations, or environmental standards that are already set.

If you’re thinking that the process may be something that you can carry out all by yourself, think again. It is not advisable that vacuum testing be done alone and without any professional help. In fact, NADCA rules provide that such testing and analysis should be conducted by competent third parties who have vast experience in vacuum testing. You may ask for more information about these people from your friends, contractors, colleagues, or relatives. Or you may use the power of the Internet to assist you in locating the most qualified persons or companies.

One basic HVAC tool is the wrench. This device is used to tighten or loosen bolts (usually those with hex heads) and nuts. There are many kinds of wrenches: open-end, combination, adjustable open-end, flare nut. Most HVAC technicians prefer using the ratchet-type box wrench. They are excellent time savers as they immediately tighten or loosen around nuts and bolts. For refrigeration and air-conditioning systems, however, they go for the flare nuts. One note for you, though.  The best ones are those that are made of alloy steel because they are tough. You also check the shape of the opening, see if they can easily hold and release nuts and bolts, as well as the grip.

For HVAC systems, you also need a screwdriver. To allow it to endure twisting torque, choose a screwdriver with tempered tips. Good ones are also with steel shafts. In using this tool, you have to remember some few things. First, a screwdriver can never replace a chisel or a pry bar. Select the most appropriate device needed at the moment. Second, it is necessary that you maintain the form of the screwdriver’s tip to avoid damage to the implement or injury to yourself.

Pliers are used to hold little objects or to bend or cut wires. Just like the other tools mentioned, there a variety of pliers available that come in different shapes and sizes. The most ideal for pipe work is the locking-type pliers (Vise-Grips). These pliers have the most effective holding power. Tension degrees are also adjustable. Pliers should never replace wrenches.

Another classic HVAC tool is the hammer, specifically a duct hammer. This is used when installing ducts and air distribution systems. Generally, its face is square and has a chisel-like back. In selecting the right hammer, its handle should be made of steel, wood, or fiberglass. Otherwise, more-than-enough pressure will bend or even break it.

A hacksaw can cut piping materials but not with the ones used for piping circuits that carry refrigerants. Other valuable tools are drills, meters, and gauges.

You can go to your nearest hardware store or shop online when purchasing HVAC tools. There is an extensive list of HVAC tools manufacturers and sellers that offer the best buys and quality products. HVACtool.com carries the widest range of HVAC products from various manufacturers like Amprobe, Fieldpiece, Maglite, to name a few.

Yet technology is starting to play a key role in the development of HVAC tools. There are already software programs available like Elite and Design-Build 6.0 that can do accurate load calculations and duct sizing, among others, without using any more hand tools. Furthermore, you can practically build your desired HVAC system from scratch, allowing you greater freedom to choose and identify other much-needed HVAC tools.

The truth is it is improbable and impossible to build something without anything to help you get by. In installing and even maintaining an effective and proper HVAC system, you need to have the right kinds of tools—that is, they are really useful in helping you implement your plan. And since they are the likely the same devices you’re going to use in the future, you need to take care of them. They should always be cleaned and not utilized inappropriately. Handling them with care will not only make them long-lasting but, it will also protect you from injury or accidents.

You can also try to shop online—scout or browse through the Internet a lot of these supplies. The good thing about shopping through the Web is that most of these companies provide photos as well as prices for their products. Thus, canvassing for the most appropriate tool is relatively easy. Most of all, most of the products offered are accompanied with their basic description and function. But you must be aware from being enticed by other people’s empty words. Some of what you’re reading and learning may just be superficial and mere exaggerations. You may end up using the worst HVAC supplies available.

There are many companies that sell HVAC supplies and tools. For example, York is the largest and leading heating and air-conditioning supplier for residential, industrial, and commercial purposes in the United Kingdom. Furthermore, York HVAC parts are one of the best in the market.

You also have the option of searching them online. For example, if you’re seeking for an HVAC supply company in New Jersey, you can refer to kellysearch.com.

One of the firms that distribute good-quality supplies is arnoldservice.com. They provide HVAC supplies in different states such as Massachusetts. Their duct tapes are excellent since once you’ve taped them, they never get off, and they remain stuck for a very long time, even lasting for years.

Another site that you can actually refer to is grainger.com. They have a wide variety of HVAC supplies, namely, AC refrigeration, blowers, central equipment, filters, exhaust fans, controls, and a lot more. And you can eventually go very specific on them. For example, if you’re thinking of purchasing HVAC controls, particularly relays, grainger.com offers you different kinds of them such as cooling equipment relays, pneumatic relays, and switching relays.

Other big companies such as Trane also produce and sell their own HVAC supplies and accessories. Trane has antivibration pads; different types of fittings such as copper fitting, CPVC pipe and fittings, cement-PVC pipe and fittings; drain pans; duct smoke detectors; HVAC sheet metal supplies, and paints, among others.

However, buying them personally is not your only choice. If you believe that you are not a good judge as to what tool or HVAC supply to use, you may rely on the judgment of other professionals, such as HVAC contractors. You can actually reduce your overall costs and fees especially if you avail the services of only one contractor as they have steady approach to the purchase as well as supply of the materials, tools, and equipment. They also have control and are accountable for any loss of these supplies or instrument. For repairs, you may eventually ask your own HVAC technician to also include along with his service the purchase of HVAC supply.

If you really don’t want to buy any but simply want updates about the different HVAC supplies—what’s in and what’s out, how they fare in the market today, the common HVAC supplies trend nowadays—you may go to hvac-supplies.it. You can discover a lot of informative articles and information about HVAC supplies. These write-ups are not only limited to stories happening in the United States but also cover those from the other countries. For example, an online piece about the multiple uses of M2M, which include the HVAC system, is originally from the United Kingdom.

Finding it hard to look for HVAC supplies? Indeed, the answer is located both in and outside the World Wide Web.

Surfing the Web will help you find a number of companies that sell HVAC software.

Carmel Software, a company located in San Francisco Bay area and operating since 1995, has recently introduced into the market their newest product called Design-Build 6.0. This is a set of programs that performs design-build analysis. The beauty of it lies on its flexibility. For example, its two kinds of load calculations, LoadSoft 6.0 and Residential 5.0, make Design-Build 6.0 applicable to both commercial and residential facilities. This tool also contains other data such as construction types, ASHRAE (American Society of Heating, Refrigerating & Air Conditioning Engineers) fittings, and HVAC parts database useful for the various programs of Design-Build 6.0.

Engineers, designers, contractors, and other interested individuals can take advantage of MeMate HVAC. It is a simple, user-friendly interface that gives you the ultimate freedom of designing an HVAC job from scratch well as of estimating costs in the shortest period of time. This software allows you to calculate heating and cooling load, choose the most appropriate device for air distribution, identify variable air terminal units, design ducts, and estimate costs, along with other useful functions.  You can also download a demo from the Web site. Using the demo will give you a better idea of how the system works.  You can also find a  manual on their site that provides step-by-step instructions  on what the different procedures involve.

The most popular HVAC software from Elite Software is Rhvac, which is used to calculate temperature loads of residential buildings and small commercial facilities. It has a built-in ACCA Manual J, the recognized standard for residential load calculation. But aside from peak heating and cooling calculations, the software also has the ability to measure its duct sizes and their static pressure loss. You can also use this program in creating proposals as well as in choosing the best HVAC equipment to use. Its Drawing Board software, however, is sold separately.

HVAC Estimator contains ready-to-use, easy-to-manipulate documents such as HVAC service agreement templates, helping you create and print contracts, proposals, reports, and other essential papers at the shortest time possible. You can select among the various types of contracts, alter the verbiage, insert a logo, or change autofill tags’ position to make the contract look more consistent and businesslike.

Yet don’t be misled that HVAC softwares are only limited to and available for desktop PCs. Handheld computers and PCs can use Silverglance’s HVAC software. The program also has the same function as other programs like Elite Software and Design-Build 6.0. It can still calculate pipe sizes, convert units, conduct time factor, and other related procedures.

Like any other kind of shopping, there are many factors that should be looked into when choosing the right kind of software. Definitely, picking and purchasing one that is more appropriate for bigger facilities will only prove to be somehow useless if you’re only considering installing an HVAC system for your home. Price is also one of the important aspects to be considered.  The sites mentioned have their own price lists for the different software packages they carry. You can view them, and then you determine which for you is the best. You can also visit stores, ask colleagues and other friends who are using their own HVAC program, or personally call the different software companies to help you come up with the best decision.

With all the technicalities involve with an HVAC system installation, having your own software in your PC, handheld or desktop, can simplify almost everything.

First, HVAC equipment that are in the right sizes are inexpensive to install. More often than not, an oversize HVAC equipment uses up a lot of energy, thus increasing your electrical energy consumption. Having the right sizes can help you save energy and money as well. A right-sized equipment also decreases operation and maintenance costs. An oversized HVAC equipment function at shorter periods while the undersized are required to run longer to meet the much-needed load. Both are not economical. Accurate air-conditioner sizes regulate humidity better, minimizing growth of molds and thus maintaining a healthy environment. Usually, oversized air conditioners perform lesser dehumidification due to shorter cycling.

Furthermore, HVAC sizing decreases callbacks. Yet the need for conducting HVAC sizing can either be by choice or by circumstance. There are, in fact, some states in America such as California that require load calculations. Whatever is the case, whether you have an option or not, it’s always preferred to calculate the sizes of your HVAC equipment.
The principles and the applications of accurate HVAC sizing are based on ACCA’s (Air-conditioning Contractors of America) guidelines for measuring HVAC sizes of equipment. This manual called ACCA Manual J Residential Load Calculation allows contractors and owners alike to correctly approximate the loading capacities of their heating and air-conditioning systems. A building’s heat loss can be calculated through its air infiltration on doors and windows, leaky ducts, as well as ceilings and walls. Another source for load calculation is the facility’s design condition.

It is imperative, however, that load calculation should be done per room for proper ductwork sizing. Measurements of air infiltration should be approximated, or you may perform a blower-door test.  This test can actually give a more accurate calculation of HVAC sizes and should be conducted in retrofit applications. Infiltec.com provides the most comprehensive procedures and tips in conducting the blower-door test. Though this examination will often result to a higher design cost, you are assured of accurate HVAC size calculations. Most of all, it costs more to maintain oversize HVAC equipment in your building.

It is relatively easy to follow the guidelines set by manual J. House plans are ideal sources of information that are practically used in sizing load calculations of the cooling systems installed in new houses. You can also get other valuable details in window type, glazing, house’s orientation, solar gain, and shading from building overhangs.

If you are a contractor or a builder, there are some things you must always remember when you’re sizing HVAC equipment:

- As much as possible, don’t rely on the “rule of thumb.” This system may work, but you can never be assured of its efficiency.
- You might not be bothered by those almost-inaudible roars of air conditioners. This may just be a common scenario. But what you don’t know, these units may not be appropriate for the cooling load—they are simply oversized. To prevent taking unnecessary risks and damages, follow the rules stated in the manual. For sure, it’s safer that way.

The individuals mentioned are expected to offer the best, if not the most superior, kind of service to their customers. Thus, the demand of a system, such as a software, to further enhance this aspect is high. Fortunately, a number of companies are trying to meet this demand. For example, HVAC contractors can definitely benefit from the service management software suite called Data-Basics from Sam Pro Enterprises. It is known to reduce cost and increase efficiency of your overall HVAC system contracting service. Since the different processes involve in contracting will be performed better, you can further the growth of your client base without the need of increasing support costs. Also included in the software package are the different conversion tools for an easy upgrade of upcoming Sam Pro HVAC service softwares.

Data-Basics aims on assisting contractors in the following aspects, among others:

- Establishing preventive maintenance schedules of HVAC as well as updating status of work orders
- Receiving sales leads and creating price quotes
- Integrating all HVAC service work
- Executing reports and sending automated communications

For more than 20 years, Coastal Computer Corporation has been assisting contractors in terms of their HVAC service management softwares. Their recent and perhaps most popular program is Electronic Service Control (ESC), which contains the industry’s best dispatch board.  ESC is a powerful service management tool that is also famous for its flexibility and simplicity. Most of all, it is user-friendly. Other features include the ability to track every technician’s productivity and supply the most detailed history report for every work performed on clients. ESC also has built-in inventory and mobile computing features. The former allows you to easily calculate your product markup, conduct wide-ranging inventory reporting, or compute multilevel prices. Its mobile computing capability, on the other hand, permits technicians to connect to computers found in offices for easy monitoring of service calls or GPS, for bringing records up to date, and creating invoices.

You can certainly depend on their proven track record, which includes cutting staff dispatching to 2 hours and limiting issued invoices to hours instead of weeks, to name a few. Add-ons are e-mail options, accounting packages’ integration, deployment customization, and a lot, lot more. However, for software installation, you have to meet its system requirements first. A CD-ROM is also essential.

An HVAC relay uses either one or perhaps more central controllers to regulate terminal unit controllers that are remote, communicating through an operator interface, usually one or more PCs. An HVAC relay is also often integrated with other systems such as smoke, fire, or light controls.

There are many types of HVAC relays available in the market. Temco Controls has actually three HVAC relays. Their MR3000 is a general-purpose mechanical relay and fits for both low voltage as well as excellent power switching. To activate it, it needs only 10–12 VDC (voltage direct current) at 100ma (milliampere) for its low-power coil. Its double-pole, double-throw (DPDT) relay is estimated to be at 10A (ampere). Each relay consists of LED that indicates its voltage status. Its mechanical relay board is a slight modification of MR3000. They are actually two types of it: 4- and 8-gang versions. Its features are very similar to that of an ordinary MR3000 mechanical relay in the sense that it still has a low-power coil and possesses LED lights for each relays. Additional LEDs are used to monitor fuse loads. The mechanical board relay’s jumper can be set in two modes. It can be switched at 24 VAC on common ground, or you can use dry contact mode.

Temco Control’s SSR3000 features photo isolation of 4,000 volts and voltage turn-on, among others. It is a type of a solid-state relay. However, the word “relay” may be a misnomer as it isn’t a relay at all. It depends on electronics to do the actual switching. SSR3000 is known to provide solid-sate dependability for your HVAC systems.  For best performance, each relay is pretested before it is delivered.

Fujitsu Components America is one of the world’s leading manufacturers and distributors of electronic parts all throughout America. In 2004, it introduced and released into the market its newest type of HVAC relay called FTR-K3. It is a slim relay with a power of 20 amperes and an operating power of 780mW (milliwatts), the lowest of among its class. It has variety of uses, such as to switch compressor and inverter loads found in air conditioners and other appliances found in offices and in homes.  FTR-K3 is very durable and long-lasting, capable of 2 million operations (its mechanical life) or 100,000 operations (its electrical life) at its rated load.

Another leading company in the mechanical engineering industry is American Zettler. It boasts of being world’s no. 1 manufacturer and seller of HVAC relays. Its catalog or product list, which you can download, features over thirty kinds of relays for different purposes. Furthermore, each model has its own distinctive characteristic, allowing you to choose the best or the most appropriate for your need.

Omron has one of the best kinds of contactor relays. They consist of main contactors with an addition of contact blocks. Moreover, their components are finger proof and come in different sizes; definitely, you have almost infinite ways of possible configuration.

HVAC relays are sometimes manufactured as part of “power packs.” We can take, for example, Leviton’s occupancy sensors, which are the most highly developed, functioning sensors in the market. These sensors, along with its own built-in HVAC relays, can actually place all control connections in one central location.  Computers can also be used to control HVAC relay operations through an open- or closed-contact representation. This is because PCs use binary logic—either one or zero, yes or no, true or false—that is transformed into electrical signals and eventually into true-or-false digital signals.

One of the essential procedures in HVAC cleaning is duct cleaning. Ducts transfer air between spaces in enclosed areas to continuously maintain good air quality in enclosed facilities. What you might don’t know is that though they are beneficial and necessary in HVAC, they are also good habitats for molds (especially when there’s high moisture level), rodents and other insects, and other minute particles. Worse, viruses can transfer to human bodies by inhaling dust particulates.
Cleaning ducts, however, hardly deters the overall efficiency of the system. Thus, the U.S. Environmental Protection Agency (EPA) recommends cleaning ducts on as-needed basis only. You might also encounter times when cleaning providers would suggest using chemicals to kill microorganisms or sealants to prohibit dust and other particles from being released. A better understanding of their advantages and disadvantages is necessary. There are not enough researches to conclude that they are indeed useful, and thus, proper information should be gathered and/or disseminated before you can actually give permission.

Aside from ducts, other components such as air fixture HVAC systems and air-conditioning registers should also be properly maintained, and usually, their cleaning schedules vary. Some like cleaning or replacing filters, or coil and fan blades of unit heaters, require quarterly or as-needed cleaning. Maintenance for return air fan should be monthly, except for cleaning its fan and lower blades, which can be done annually. Cleaning roof drains is weekly while an IAQ (indoor air quality) audit is to be executed quarterly. The ultimate key here is to actually have a schedule. Most companies right now have adopted this method to continuously and consistently ensure consistency the HVAC system’s maximum performance. If you still don’t have any schedule, then it’s time for you to create one.

Just like in cleaning air ducts, you have the option of cleaning these other components yourself or you may take advantage of HVAC cleaning services. But in order for you to perform this task, you should be equipped with the proper tools and equipment, knowledge and skill, as well as experience. You can get a lot of do-it-yourself books and tips in the bookstore or in the Web. But then, extraprecautionary measures should be undertaken to prevent accidents or being exposed to harmful effects. If you’re not so confident of taking any risks, then you can always ask for other people’s expertise. Caution, though, should be observed.

You might just be hiring the wrong person, and instead of improving your HVAC system, more damage is done, putting you in danger or making you spend more than what you hoped for. You choose cleaning providers that are reliable, competent, have excellent track record, and can give the best service possible. You may ask references from your friends, colleagues, or use the Internet. There are absolutely a lot of Web sites and links that can give you a valuable list of HVAC cleaning providers all over the country. You can visit their respective Web pages too and check out their profiles just to help you decide.

Like any other object that is prone to wear and tear, HVAC systems are vulnerable to deterioration if not properly maintained. So let your system have the opportunity to serve you better. Maintain its components’ cleanliness.

Now that you have your resume, it’s time for you to let those different companies know how capable you are in an HVAC job. Search engines produce multitudes of Web sites that can help you in finding a job by posting your resume. Some sites give you the option which state to apply or what company you like to join. Others are specific for certain places.
One of the leading and major employment portals that offer beautiful benefits to employers and jobseekers is hvacagent.com.

For a minimum monthly fee, members can apply to thousands of jobs posted every day. And since the company values confidentiality so much, presently employed applicants don’t have to worry about jeopardizing their current employment—employers cannot freely search profiles or resumes.

On the other hand, employers have the chance to choose any applicant according to the state of their choice. What’s more, their services don’t simply end on cyberspace. With the main objective of creating its own resources’ pool, hvacagent.com can actually search for other resumes and profiles posted in six other Internet career sites. Aside from advertising online, they also publish ads in statewide newspapers. A tie-up with the News, the major publisher in HVAC industry, exposes you weekly to other professionals. And you don’t get any charges for hiring someone.

Yet every jobseeker should remember that companies will always hire the most qualified person, who has the potential to greatly contribute to the development of their products and services. Thus, if you feel that your knowledge and skills are inadequate for you to land a job or you simply want to be more competitive, then you can get yourself enrolled in online HVAC training courses. HVACSource.com , in partnership with Penn Foster Career School, provides a comprehensive list of top-notch state-accredited HVAC courses you can take anytime and anywhere. Diplomas are given right after taking the courses.

There are many challenges in looking for a job. There are times when your application gets rejected, you don’t find the right job for you, or you just think that the employers can’t help you in achieving your desired career path. Whatever the struggle is, it doesn’t take away the fact that making your HVAC career projections is relatively easy. You can just wait for another day to come because for sure, there will be another hundreds and hundreds of jobs that will be made available for you.

At this point, you may have a clearer idea of how the whole setup goes. Now, the real struggle is finding the most appropriate HVAC tools, parts, and equipment you need. You really have the option to do everything yourself. But this may actually be difficult to do as there are different models, sizes, and brands for the huge, comprehensive HVAC product line, offering you with limitless possibilities; and you have to make sure that all components should be compatible with one another. You may just catch yourself in the middle of a dilemma. It is really a big help therefore to hire your own contractor and ask for their opinion or advice.

For sure, they have the right ones in mind for you. Or you may just leave the decision entirely to them. You have to check first, though, that the contractor is legal. For instance, he or she should have a Florida universal HVAC license, in case you like to get service from Florida, and fully insured. If the contractor is in Kentucky, he or she should have Kentucky HVAC liability insurance. This assures home and building owners that in case of any damage to the property, due to mistakes made by contractors or any of his or her workers, an insurance company will pay for the repair.

Good-quality products last longer, but it’s the proper installation of the HVAC system that should be your main priority to ensure safety and avoid spending unnecessarily in the future. First, you or the contractor should be able to follow the different city and state codes and other requirements needed when installing the system. For example, flue pipes are necessary to bring your replaced furnaces up to code. This ensures that poisonous gases are removed properly from the dwelling. Refrigerant lines and service accessibility should also be taken care of. These codes, however, give only minimum protection. You or the contractor should meet quality working standards. To better your HVAC skills, you may enroll yourself to good trading schools or take HVAC online courses.

You may refer to a number of companies such as Montgomery Ward or Sears to get the best price estimates, though there are some common factors that affect prices, specifically installation costs. But no matter how much you pay, you have to see to it that you’re not putting quality into jeopardy. Hiring a contractor may cost you about $200–$500. This, however, saves you a lot of time. You just have to know the warranties and guarantees, the policies—the boons and the banes—of your choice contractor.

You should also learn how to distinguish technicians from salespersons. A lot of people put too much confidence on those who dress neatly and talk confidently while doubt those that look dirty and unkempt. Most salespeople don’t have technical background and are often driven by commission. Their main concern is closing a sale. Definitely, they offer less technical help. The best persons to approach, aside from your contractors, are the technicians. These people are schooled, trained, and skilled to do just the right kind of HVAC job. They are more committed to perfecting their work and are reliable when it comes to improvements or repairs.

For other references, there are books you can purchase in bookstores or in the Internet. James E. Brumbaugh’s Audel HVAC Fundamentals: Air Conditioning, Heat Pumps and Distribution Systems, Peter Scott Curtiss and Newton Breth’s HVAC: Instant Answers, and Redwood Kardon’s Code Check: HVAC: A Field Guide to Heating and Cooling are good examples.

There are many HVAC consulting firms scattered all over the world, and they all offer top-caliber consulting services. Some of these are discussed here.

Asian countries like Thailand and Malaysia can benefit from the consulting services of CMD Asia. This company addresses the need of building owners to cope up with the changes in services design and equipment by eliminating the common problems in installation and operation of HVAC as well as in commissioning. Their highly specialized HVAC services include the following:

·    Commissioning
·    Performance surveys
·    GME2 ductwork
·    Inspection and cleaning
·    Testing instrumentation
·    Operation and maintenance
·    Cleanroom testing and certification

Trinidad Engineering has been providing HVAC consulting services to widest range of clients in various industries for so many years. This company is highly committed to reducing operating costs, eradicating downtime, and hitting or surpassing code regulations. Their engineers are capable primarily with engineering design, which includes AutoCAD drawing and specs writing. They are also highly trained in other engineering aspects such as in industrial control and are expert troubleshooters who can identify problems and execute optimum solutions in the existing HVAC system.

Trinidad Engineering is a small company; but it takes pride in providing exceptional services to their growing list of clients through its special alliances with other engineering organizations who will work as subcontractors. These firms offer structural, architectural, and other engineering designs that allow you to save more money without jeopardizing your much-needed HVAC engineering services.

Trinidad Engineering views each project as unique. Thus, availing their consulting services entitles you, as their much-valued customer, their company-developed customized testing method. The test provides you with a lot of essential and necessary data to further maximize the use of your HVAC systems. One of these is the generation of an energy-usage report. Their innovative minds also produced a specialized data gathering equipment for problem analysis.
One of the premier engineering institutions in HVAC consulting industry is KJWW Engineering Consultants in Rock Island, Illinois.

So far, they have remained to be one of the top-ranking design and mechanical/electrical engineering firms in the United States. They have also garnered the prestigious International ASHRAE Awards for two of their notable projects: development of a geothermal-pond-supported underfloor air distribution system for a Des Moines Area Community College classroom building as well as for their innovation of saving about 37 percent energy costs for a greenfield replacement hospital through its unique geothermal system.

KJWW Engineering Consultants is the largest consulting service in the Midwest. Their market covers commercial offices, government buildings, health care facilities, communities, and many others. Their state-accredited and certified mechanical, structural, and electrical engineers collaborate with customers to come up with the most sound HVAC design that is effective and generates savings.

Yet aside from the advantages these companies present, HVAC consulting services are also essential to minimize or, most of all, avoid higher future operating and maintenance costs because of faulty installations or defective mechanical design. For instance, Trinidad Engineering replaces with updated technology those obsolete, not-so-effective systems. They also set up controls to efficiently monitor energy consumption.

Choosing the best HVAC consulting service is needed so you will not only get the best kind of service but the most excellent cost-effective measures as well, saving you from major unnecessary expenses.

Usually, HVAC commissioning is performed in newly constructed buildings. However, this can also be administered in existing facilities. The most important thing is you are taking steps in saving energy to decrease expenses while monitoring system performance.

It is advisable for building owners to acquire the services of an independent commissioning agent especially if construction is on its final stages. Commissioning settles a lot of miscommunication especially for those who have limited or no idea about HVAC systems. A commissioning agent can be an independent, third-party person or team that is not involved in any HVAC system design, installation, or maintenance. You can actually ask references from your friends, colleagues, or find one online. There are basically many agents and companies that offer various kinds of commissioning conditions and benefits, giving you a wide variety of options.

One company can be KBPE Engineering Services. This firm founded by Ken Barber is located in Seattle, Washington. Their association with other engineering organizations as well as their experiences helped them in keeping up with the expectations of building owners. They have a pool of highly gifted engineers and professionals who are experts in HVAC commissioning. Or if you want to prevent additional cost, you may rely on the analysis or report of your architectural engineers or even your own judgment. But the advantage of hiring a commissioning agent is that he or she can provide the most objective, unbiased conclusion and recommendation. For instance, it is typical for an architectural engineer to hide any flaws or defects in his or her work by concluding that system performance is at par or even surpasses the expectations of the owner. In the end, when you think all systems are running well, you may suddenly find yourself encountering multitudes of HVAC system’s deficiencies.

Taye Services Limited offers air-conditioning supply, design, and installation in London. This company is also highly engaged in commissioning. Their many years of practice help them comprehend every client’s needs and provide the proper solutions for a much better indoor air quality.

There are some basic tools used when commissioning. The differential pressure meter determines the water flow of heating and chilled water in pipes and coils. A psychrometer, meanwhile, identifies relative air humidity through dry- and wet-bulb temperature. To measure velocity of air in ducts, a hotwire anemometer is used. Other instruments may include the following:

·    Electronic micromanometer
·    Air flow capture hood
·    Test plugs
·    Liquid manometer

HVAC commissioning generally relies on the guidelines promulgated by the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE). Guideline 1-1996 of SHRAE provides an outline of HVAC commissioning procedures—starting from HVAC’s predesign to postoccupancy phase—but excludes other building construction components. The rules are highly ideal for owners, contractors, and architectural engineers since they offer preparation procedures for documentation of design intent, expected performance, and analysis of functional performance testing, to name a few. Aside from these, Guideline 1-1996 devises a training program for operation and maintenance personnel.

The success of an HVAC commissioning doesn’t just rest upon the agent. Every individual that is part of the whole building process—the engineers, system designer, the building owner, and the commissioning agent—should closely work together to produce an HVAC system that will last for a long, long time.

One of the essential procedures in HVAC cleaning is duct cleaning. Ducts transfer air between spaces in enclosed areas to continuously maintain good air quality in enclosed facilities. What you might don’t know is that though they are beneficial and necessary in HVAC, they are also good habitats for molds (especially when there’s high moisture level), rodents and other insects, and other minute particles.

Some like cleaning or replacing filters, or coil and fan blades of unit heaters, require quarterly or as-needed cleaning.
