In air conditioning and refrigeration systems, capacitors are used to store electrical energy and provide an additional power boost to the compressor motor or fan motor. A capacitor is an electrical component consisting of two conductive plates separated by a dielectric (a material that does not conduct electricity).
A contactor for HVAC (heating, ventilation, and air conditioning) is an electrical switch that is used to control the flow of electricity to the various components of an HVAC system.
An air conditioner window bracket is a support system designed to securely hold an air conditioning unit in place.
