Compressor
Definition and meaning of Compressor in real estate.
A compressor is the mechanical component of an air conditioning or refrigeration system that pumps and compresses refrigerant gas, allowing it to heat up and cool down as it circulates.
In more detail
The compressor works by drawing low-pressure, cool refrigerant gas from inside the home and compressing it into a high-pressure, hot gas. This hot gas is then sent through the outdoor coils to release heat before turning into a liquid and returning inside to absorb heat from the indoor air.
Because the compressor is under high pressure and runs frequently during hot weather, it is one of the most expensive parts of an air conditioning system to replace. Home inspectors check the compressor during a sale to ensure it operates quietly and efficiently. Home buyers should pay attention to the age of the unit, as a failing compressor often means a whole new system is needed.
Key facts
| Category | Property Types & Construction |
|---|---|
| Location | Typically housed in the outdoor condenser unit |
| Function | Circulates and compresses refrigerant to transfer heat out of the home |
| Maintenance | Requires clean filters, clear airflow around the unit, and regular servicing |
During a routine home inspection, the inspector notes that the outdoor air conditioning compressor is making a loud grinding noise, indicating it may be nearing the end of its lifespan.
Frequently asked questions
What are signs that an air conditioner compressor is failing?
Common signs include warm air blowing from the vents, loud or unusual noises from the outdoor unit, and the system frequently turning on and off.
Is it better to replace a broken compressor or the entire air conditioning unit?
If the system is older, it is typically more cost-effective to replace the entire outdoor unit rather than just the compressor, as newer units offer better efficiency and warranties.
