HVAC Fresh Air Inlet

When it comes down to selecting a HVAC college program, the most important point that you must find out is that your preferred destination college you have selected has the necessary accreditations. This is an extremely important factor, since it means that the training program provided will be at par with the standards specified by professional HVAC organizations.

The premier accrediting agency for HVAC training programs are the NCCEA, which is 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 need to select that has a minimum of at least one accreditation.

Smaller class sizes are also important, which means you will get one to one assistance from the instructors. The best colleges teaching HVAC courses will also have an on-campus science laboratory with modern equipment. Before enrolling make sure you visit and explore the campus and get a feel for the place, the teaching areas, the facilities available and talk to the teachers, if possible. You should also find out whether they allow any flexibility in scheduling classes for students with external jobs, and how you might go about researching financial aid, if required.

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.
