An HVAC system in which some components are located indoors, such as the furnace, and some are located outdoors, such as the air conditioner. More common to residential and replacement applications.

Used to rate the energy efficiency of air conditioners, SEER is the ratio between the amount of cooling output a unit produces during a typical cooling season divided by the total amount of electricit [..]

Two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.

Part of an air conditioner or heat pump that compresses refrigerant in a circular motion (as opposed to up-and-down piston action) for quiet, efficient and more reliable operation.
