  HVAC - Wikipedia, the free encyclopedia
HVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism/acronym that stands for "heating, ventilation and air-conditioning".
These three functions are closely interrelated, as they control the temperature and humidity of the air within a building in addition to providing for smoke control, maintaining pressure relationships between spaces, and providing fresh air for occupants.
Thermostats control the operation of HVAC systems, turning on the heating or cooling systems to bring the building to the set temperature.

 Indoor Air Quality (IAQ) Resources by Building Air Quality   (Site not responding. Last check: 2007-11-05)
If the HVAC systems are not able to control existing air contaminants and ensure thermal comfort (temperature and humidity conditions that are comfortable for most occupants) then indoor air quality complaints can occur.
The HVAC system includes all heating, cooling, and ventilation equipment serving a building: furnaces or boilers, chillers, cooling towers, air handling units, exhaust fans, ductwork, filters, steam (or heating water) piping.
HVAC designs may also include units that introduce 100% outdoor air or that simply transfer air within the building.
