When it comes to learning about your air conditioner, the AC compressor is a good place to start because it is of key importance to the functionality of the AC. Understanding what the compressor does, common problems associated with it and signs of trouble will help you stay proactive with your AC’s care.
What is an AC Compressor?
When you think about an AC requiring electricity to run, you’re thinking about the compressor, which is run by an electric motor in the outside unit of a central air system. The AC compressor, true to its name, circulates the refrigerant through the coils by compressing it.
Compression turns the gaseous refrigerant from the evaporator coils into a high-pressure gas, forcing it through the compressor coils. As it travels, the refrigerant releases its heat, returning to liquid form, and continues to the evaporator coils. Here, it becomes a heated gas again, and the heat exchange is repeated.
Common Compressor Issues
An AC compressor is essential to the function of an air conditioner, as the cooling cycle stops without it. Dust and grime can cause the compressor to get stuck, which usually requires replacement to fix.
Leaks and other malfunctions with the compressor are also common. Remember that the compressor is subject to the same wear and tear that any other motor is, especially during hot, Texas summers.
Signs of a Bad Compressor
If your AC compressor is already broken, your cooling cycle won’t happen. However, there are several signs of a failing AC compressor that could alert you of the need for repairs before you get stuck in the heat. To prevent a complete AC breakdown, keep an eye out for the following:
- Rattling or ticking noises
- Less airflow
- Warmer air coming from the vents
- Moisture leaks around the AC unit (outside)
If you notice any of these signs or your AC stops running altogether, contact the professionals at Champion AC immediately. Champion AC is the AC repair company San Antonio residents trust for all their compressor repair needs.
