Ductless Mini Split in Rio Rancho – What Is an HVAC Coil?

A heating, ventilation and air conditioning (HVAC) coil is part of an air conditioning and heating system. There are actually two HVAC coils in a typical system. There is a condenser coil in the external air conditioning condenser and an evaporator coil in the indoor unit. The coils are what increase or decrease the temperature and pressure of the coolant gas or liquid before passing it to another section of the HVAC system.

To understand how the coils work, one first must understand how an HVAC system works. In simplest terms, the HVAC system pulls hot air into the system, cools it, then distributes it throughout the building. In winter, the system pulls cold air in, extracts the heat from it and passes that heated air through the ductwork in the building. HVAC coils play an important role in this process.

The compressor in the exterior unit is a pump that pulls hot, low pressure refrigerant or coolant gas from inside a building and will convert it into hot, compressed gas. That hotter gas is forced over the exterior coil and gets cooled off as the hot air from inside the building is blown to the exterior.

The loss of heat from the coolant, however, turns the gas into a liquid form that is still very hot and pressurized. The liquid flows into the evaporator coil that is found in the inside HVAC unit. As the liquid enters the evaporator HVAC coil, it is able to expand and cool.
