Heating, ventilation and air conditioning (HVAC), is the combination of different technologies that control temperature, humidity, and purity of air within an enclosed space. Its purpose is to provide indoor comfort and acceptable indoor air quality.
The use of furnaces, space heaters, and boilers as a method of indoor heating could result in incomplete combustion and the emission of carbon monoxide, nitrogen oxides, formaldehyde, volatile organic compounds, and other combustion byproducts. Incomplete combustion occurs when there is insufficient oxygen; the inputs are fuels containing various contaminants and the outputs are harmful byproducts, most dangerously carbon monoxide, which is a tasteless and odorless gas with serious adverse health effects.
In addition to traditional heating and cooling systems, there are options for improving the indoor air quality with Trane CleanEffects air cleaners, adding climate zones with ComfortLink(tm), II Zoning Systems, and taking advantage of the most recent smart home connected thermostat controls.
