The North American HVAC (Heating, Ventilating, & Air Conditioning) industry consists of diverse segments serving residential, commercial, and institutional mechanical systems. HVAC is becoming an increasingly technical playing field, creating dynamic standards and driving product innovations. HVAC installations are gradually becoming the work of specialized, rather than general contractors.

Trends toward energy efficiency and environmental awareness continue to fuel the retro-fit market for all HVAC systems. Nearly 2/3 of the $173 billion dollars generated by the industry is allocated to modernization, maintenance, repair, and retro-fit projects. At the residential level, governments are creating incentives to help homeowners consume less energy and save on bills. At the non-residential level, owners are increasingly conscious of the operational dollars saved when HVAC systems are designed professionally.
