What is heating, ventilation and air-conditioning (HVAC)
The main purposes of a heating, ventilation and air-conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems control the overall climate in the building. They also make the proper adjustments whenever we experience changes in outdoor temperature. In hotter times of the season, the HVAC systems regulate air temperature by providing the necessary cooling to keep the entire building comfortable. HVACcontractors provide a better quality of air indoors and involves the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases as well as temperature control and oxygen replenishment.
