Ever since mankind began to industrialize, environmentalism has been a constant dilemma. From the coal-stained streets of London to the Great Pacific Garbage Patch, we have always traded the destruction of one existing circumstance for our personal comfort and survival. The question has always been the same: how can we have our cake and recycle it too?
In the case of heating and cooling our homes, human beings have actually begun to be relatively successful. Of course, every HVAC system is dependent on existing power grids, but designers in the 21st century have been remarkably ingenious in maximizing their efficiency and minimalizing their impact on the environment, to the point where whole businesses have sprung up specializing in environmentally conscious HVAC systems.
What Counts As A Green HVAC?
Heating, ventilation and air conditioning businesses have continually grown over the years, improving on environmental augmentation with new technologies and new materials. In this light, adding tree hugging to the industry is a natural and necessary development, made official by the Environmental Protection Agency’s legal muscle.
The US Green Building Council established The Leadership in Energy and Environmental Design (LEED) rating system in 1998, a third-party certification criteria with over 14,000 projects worldwide. Our current system rates on a gold, silver and bronze standard, with platinum for exceptionally green buildings. The new 7 World Trade Center in New York City, for example, is a LEED gold standard building with energy saving design elements like recycled steel, channeling natural sunlight and rainwater collection for cooling.
Green HVAC industry falls into the standards promoted by LEED, namely energy conservation, water efficiency and materials used or wasted. Reducing toxic by-products is also a high-level concern, especially for systems that circulate air throughout entire buildings. For the average homeowner or small building owner, installation of Energy Star heating and cooling devices is the American standard. Look for the IAQ Home Label that marks the EPA’s standard for air quality if you’re looking to purchase a home or building with a green HVAC system.
Hmm… Okay, Sell Me On This, Why Should I Get Into Green HVAC?
Green HVAC is a relatively new business venture, but it’s been quickly gaining ground in the design of new buildings for their energy saving, and thus cost-saving, benefits. As if that wasn’t appeal enough, Uncle Sam actually foots some of the bill with many Federal assistance and funding programs aimed at promoting large-scale energy efficiency. You’re likely to gain some tax exemptions from an installation as well.
What Are The Benefits And Options?
The more adventurous entrepreneur has a lot of options in this rapidly developing industry, especially for real estate developers. Blue roofs, for example, harvest rainwater for cooling, recreation or energy. Carbon dioxide sensors can be installed to maintain optimum ventilation within a building, as opposed to leaving costly circulating equipment operating throughout the length of the day. Solar panels are a long-established technology, and the planned Solar Tower in Australia is expected to provide up to 200,000 homes with electricity when completed. Smaller panels are available for installation in residential neighborhoods.
Installing energy-efficient HVAC systems is an investment in finances and environmentalism alike that should appeal to building owners looking to reboot their older HVAC systems. For example, chiller boiler systems are kind of like the gingerbread house kits for green HVAC. By using water instead of air to modulate temperature, these systems are much more efficient and can be installed in a mechanic-friendly pre-engineered pack. Companies will also appraise your property for the appropriate HVAC system, as well as possible solar or geothermal applications.
Sounds Good, Are There Any Risks?
In addition to normal HVAC business issues, Green HVAC companies have their own can of worms. Any ventilation equipment is also potential harbor for mold, and with water-cooled green systems, the potential for fungal infestation is relatively high.
New kinds of equipment inevitably have a lot of gremlins, but an experienced company will be familiar and up to date with green technology. Repairs for new equipment can be difficult or costly, but your standard HVAC equipment is very similar to your old: boiler, ducts, cooling elements. It’s likely that falling back on our old friends duct tape and elbow grease can fix a lot of these kinks.
To sum it up, yes, green HVAC has a certain element of financial risk, but there is a large buffer zone of tried and true technology. Considering the environmental and cost benefit, installing green systems is both looking to the future and looking out for our social butts.

A vocational course in heating, ventilation, and air conditioning technology (HVAC) can be a great career option for you if you are mechanically or electrically inclined. This course will teach you how to plan, design, and operate building ventilation, heating and air conditioning system. In San Diego HVAC College, students can learn their trade in a comprehensive and truly outstanding manner.
A San Diego air conditioning college enables students to choose from several certificate programs and degree programs to find what best fits their needs. Certificate programs take a shorter time to complete, while associate’s degree programs take longer. This is because completing an associate’s degree program teaches students more which generally qualifies them for more positions. Additionally, associate’s degree programs qualify graduates to take the test for EPA certification. Since EPA certification is necessary to work with many refrigerants, this is very important.
Why join HVAC College?
A HVAC course will help you along the path towards bagging a secure career, where you will be able to provide comfortable and healthy conditions for residential and commercials buildings. These courses from San Diego air conditioning colleges will not only benefit HVAC technicians, but also design engineers, plant managers, architects and so on.
The great thing about a career in this field is that the demand for HVAC technicians is expected to keep increasing in future. In fact, by 2014, some think the demand could grow by 18% to 26%. This is because the increases in population mean that there will be more and more demand for office space and building of all types. This in turn entails that people would require the latest climate control technology, within the short span of time. Thus, many expect that there will be no shortage of work for HVAC technicians in years to come.
What will the coursework include?
Those who study in a San Diego AC school will learn to service and troubleshoot HVAC and refrigeration systems. Not only this, but they will also learn about air distribution, psychometrics, thermal comfort and other facets of the HVAC industry as well. Some of the other detailed coursework that may be available includes HVAC piping systems / ductwork, energy management, and HVAC control systems.
How much will it pay?
As with any vocational course, you would like to know what a HVAC technician job pays. The US Department of Labor Bureau of Labor Statistics reports that the hourly salary for an HVAC technician is $17.43. However, for a skilled and experienced technician, the pay will be much higher – over $27.11 per hour. Obviously wages will vary from location to location, but with the right training and experience you can hope for these wages. So if you are interested in building a carrier in this field, make sure you check out the courses offered in a San Diego HVAC College. It can be what gets you on a path towards a better life.
