Although most people just assume that H.V.A.C contractors are a part of the central heat and air contractors that install both furnaces for heating and air con units for cooling, air conditioning contractors have a private history that began in the 1900s when machines for building heating and cooling units began to be established. H.V.A.C contractors became a separate part of the heating and cooling industry in 1946 and were represented by their own groups exclusively concerned with H.V.A.C.
In 1968, H.V.A.C contractors and air conditioning manufacturers joined to form the Air Conditioning & Contractors Institute. The A.R.I is concerned solely with manuals and technology or technologies that are exclusively the province of cooling or air conditioning units.
Another group formed from this endeavour to try to join heating and cooling contractors and manufacturers into one group. The merged group of heating and cooling contractors was called the National Environmental Systems Contractors Association which was later changed back to Air Conditioning Contractors of America although purportedly still representing H.V.A.C contractors in America. Obviously, the choice of names to identify themselves as heating and cooling contractors has been an ongoing issue since 1927 if not earlier when an earlier organization The National Warm Air Heating and Ventilating Association was putting out pamphlets discussing their products and services. Seemingly, air conditioning does not refer exclusively to cooling of air, it can be any artificially contrived method of maintaining the temperature of any given environment through the use of air con units.
If a contractor wants to become an H.V.A.C contractor, he will have to know not only about the various methods and products that are available in his profession; but, he will also have to know how to read the fine print involved with insurance policies and trade agreements and other information …Continue Reading
