The compressor is one of the most important parts of an AC system. It works in conjunction with the coils to transfer heat from an indoor space to an outdoor space.
Both split and packaged AC systems have a compressor. While you typically won’t see the compressor, it will turn on automatically when your AC system is running.
The Basics of AC Compressors
In an Air Conditioning system, the compressor is a motorized device that lives up to its name by compressing refrigerant. It will increase the pressure of the refrigerant so that more heat can be released, thus improving the AC system’s cooling performance.
How AC Compressors Work
AC systems rely on coils and a compressor to cool indoor spaces. They have an evaporator coil, and they have a condenser coil. Refrigerant travels in a closed loop through these coils.
While at the evaporator coil, the refrigerant will absorb heat. Upon reaching the condenser coil, it will release the heat.
The condenser coil is installed outdoors in a large metal box. Known as a condenser unit, this box also contains the compressor.
The compressor’s job is to compress the refrigerant before it reaches the condenser coil.
When compressed, refrigerant becomes warmer. Heat will always attempt to move to an adjacent cooler space. The hot and compressed refrigerant will release its heat at the coil before repeating the process.
The Importance of a Well Functioning AC Compressor
With a faulty compressor – you may encounter various problems with your AC system. Poor cooling performance is a telltale sign of a bad compressor.
Your AC system may turn on, but it could blow warm air. The compressor is needed to assist in the transfer of heat so that your AC system can cool your home.
You may hear unusual noises from the condenser unit if your AC system has a bad compressor. Compressors have a motor and like other motorized devices, they can experience mechanical problems. Mechanical problems involving the motor may result in rattling noises.
A malfunctioning compressor may even trip your home’s circuit breaker. If your AC system has a bad compressor, it may draw too much electricity, thus causing it to trip the circuit breaker.
If you are experiencing any of these symptoms you’ll need to have your AC system checked. A licensed professional will be able to diagnose your problem and get your cool air flowing again.
