What is a HVAC Contractor?

HVAC contractors are individuals who are well versed in many fields, including piping, heating, air conditioning, duct work and some electrical services. They are highly trained in the individual fields but also have expert knowledge of how systems are properly integrated into a home, office building and industrial structure. You may have come across HVAC contractors without even realizing it. Many HVAC contractors refer to themselves as offering ‘heating services’ without necessarily advertising themselves as HVAC contractors. This is due to heating being the more common terms used when potential clients are looking for specific services.
