What Does HVAC Stand For?
HVAC (pronounced h-vack or spelled out) stands for Heating, Ventilating and Air Conditioning. The three functions of heating, ventilating, and air-conditioning are closely interrelated. All seek to provide thermal comfort, acceptable indoor air quality, and reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces. Your heating and air technician goes by the name of HVAC contractor and can provide heating repair expertise.
How Does My Heating and Air Conditioning System Move Air Throughout My Home?
A fan draws indoor air in through vents called return grills located throughout your home. The air travels through ducts that run to your systems’ air handler, where it is returned into the conditioned space through supply vents or registers in your wall, ceilings or floors.
How Often Should I Replace The Filter?
Start by checking the system’s filters at least once a month. Hold the used filter up to the light and compare it to a clean “spare.” When light is obscured by captured dust and dirt particles, the old filter should be changed. Keep a record for one year and then replace the filter on that basis. At a minimum, it is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of the heating and cooling season to ensure proper operation.
