Can you repair AC units with compressor problems?

Understanding the AC Compressor

The air conditioner compressor is a vital component of an air cooling cycle, converting power into energy and circulating refrigerant for heat exchange.

Diagnosing and repairing issues with the air conditioner’s compressor is crucial, as it is responsible for circulating refrigerant through coils, powering the entire AC system.

The air conditioner compressor is often referred to as the “heart” of the air conditioning system.

How an AC Compressor Works

The air conditioner’s compressor is located in the outdoor unit and circulates refrigerant through coils.

The compressor raises the temperature and pressure of the vapor refrigerant, moving heat from the home to the condenser.

The condenser cools down the heat, “condensing” incoming refrigerant vapor into liquid.

The air conditioner’s compressor raises the pressure of the refrigerant to move to the indoor unit, repeating the process.
