What are Condensing Units for?

April 29, 2021

A condenser unit is an essential part of any HVAC system. To put it shortly, the condenser unit releases superheated air that is generated during the air circulation process. How you get superheated air while cooling your building can get a bit complex but knowing the basic parts of a condenser unit and thinking of air heating and cooling as a circular motion makes it much easier to understand.

Condenser Anatomy


Condensing Unit

Condenser box – Most of us recognize this as the loud box behind a house or building that controls the AC. The inside condenser walls are made up of coils that circulate very hot refrigerant (more on this below), releasing excess heat.

Compressor – This is located inside of the condenser unit and is considered the heart of the HVAC system. Compressors pump refrigerant in a closed loop of cold vapor to hot liquid and so on.

Fan – Located at the top of the condenser, the fan helps release excess heat built up inside the condenser coils.

The Takeaway

We know condenser units aren’t particularly attractive, but they’re the key to keeping the temperature inside of your building safely regulated, saving you money on utility bills, maintenance and equipment in the long run. Keep it clear of debris and other obstructions to keep your HVAC system in top shape for years to come.
