HVAC Fresh Air Inlet

When you decide to pick a HVAC college program, the most important point that you must ascertain is that the choice of college you have chosen is an accredited one. We cannot stress this point highly enough, as it means that the training provided will be at the required standard specified by approved HVAC organizations.

The premier accrediting agency for HVAC training programs is the NCCEA, the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. You MUST select a college that has a minimum of at least one accreditation.

It is also important to try and find small class numbers, which means you will receive personalized tuition from the instructors. A good HVAC college will also have an on college science laboratory with modern equipment. Visit the campus and get a feel for the place, the classroom, the overall facilities offered and talk to the teachers, if possible. Also find out whether there is any flexibility in scheduling classes for employed students, and also how you could go about researching financial aid, if you are eligible.

It is usually wise to locate the exhaust fans near the area where heat-producing machinery is found in the industrial building. This has the very practical advantage of exhausting this superheated air near its source and preventing a heat build-up in other areas. If side wall locations are to be utilized for air intake or exhaust, it is desirable to consider the prevailing wind direction during the summer season. If the ventilation system can be oriented to take advantage of prevailing winds, the efficiency of the system may be increased considerably, Systems that incorporate roof exhausters are usually not affected by a prevailing wind.
