One of the important HVAC systems components is the compressor or condensers coils which are normally excluded. The hot refrigerant gas is carried to a compressor to dissipate heat to the external environment and convert it into a liquid form.
This liquid refrigerant is carried through copper or aluminum tubes to the evaporator coil. Otherwise known as the condenser coil, the compressors are an essential part of your home air conditioner or heat pumps. HVAC installation professionals often place it outside, & its main job is to cool the inside of your home by leaving untreated air outside.
During such instance, condense or compress the above refrigerant, changing its state from a hot gas to cold liquids. A fan then blows air over the condenser's coil to dissipate the heat and rapidly cool the refrigerant.
