The condensing unit is an essential component of any HVAC system. In short, the condensing unit releases the superheated air that is created during the air circulation process. How you get superheated air while cooling a building can be a little complicated, but understanding the basic components of a condensing unit and thinking of air heating and cooling as a circular motion makes it easier to understand.
Condensing Box - Most of us know this as the noisy box at the back of a house or building that controls the air conditioning. The inner condenser walls consist of coils that circulate very hot refrigerant (more on this below), releasing excess heat.
Compressor - This is located inside the condensing unit and is considered the heart of the HVAC system. The compressor pumps the refrigerant in a closed cycle, from cold vapor to hot liquid, and so on.
Fan - Located on top of the condenser, the fan helps release excess heat that builds up inside the condenser coils.
Key Points
We know that condenser units aren't particularly pretty, but they are key to keeping the temperature safely regulated inside your building, saving you money on utility bills, maintenance, and equipment in the long run. Keep it clean and free of debris and other obstructions to keep your HVAC system running at its best for years to come.
