What is HVAC?

Heating, ventilation and air conditioning (HVAC) is the technology that creates environmental comfort, both thermally and air quality wise, either indoors or in a vehicle. HVAC is based on the principles of thermodynamics, fluid mechanics and heat transfer. It is an important part of residential structures such as homes, apartments, hotels, hospitals and other healthcare facilities, industrial and office buildings and anywhere else where safe and healthy building conditions are regulated.


Proper expertise in the behavior of these types of systems is essential for the analysis and repair of any HVAC device.
