The most important and widely used acronym, HVAC, stands for Heating, Ventilation, and Air Conditioning. This system controls a given space's temperature, humidity, and air quality. With that in mind, it's important to understand some key terms and keywords associated with HVAC.


Air Handler: An air handler is used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. It is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.

Condenser: A condenser is a device or unit that condenses a substance from its gaseous to its liquid state by cooling it. It is typically used to condense vaporized refrigerant that flows through the system and then returns to the compressor.

Evaporator Coil: An evaporator coil is a heat pump or air conditioning system component inside the house. The coil is filled with refrigerant, and as the refrigerant evaporates, it absorbs heat from the air in the home, cooling the air.

Heat Pump: A heat pump is a device that transfers heat energy from one location to another. It can be used to provide both heating and cooling, depending on the application. Heat pumps are exceptionally efficient in mild climates, providing heating, cooling, and hot water.

Thermostat: This mechanism measures and regulates temperature. It generally controls the temperature of a room or building by activating or deactivating a heating or cooling system.

Air Filter: Air filters are used to trap and remove airborne particles, such as dust, pollen, and mold spores, from the air. They are typically installed in air conditioning and heating systems to improve air quality and reduce the amount of dust and other particles in the air.
