The heart of your HVAC system is the compressor. It emits heat as a normal part of the process. However, if it becomes too warm, your system will shut down.

Compressor thermal overload is a common malfunction. And it typically happens on the coldest or warmest days of the year, when your system is working its hardest. A compressor overload is commonplace; it’s also one of the most expensive problems your system can have. Depending on the age of your system, it could result in the need for a complete system replacement.Don’t Overload Your HVAC Unit

Compressor overload is often caused by homeowner neglect and/or poor installation or maintenance habits, including:

  • A dirty air filter
  • Dirty condenser coils
  • Refrigeration leaks
  • Moisture in the system
  • Lack of airflow
  • Loose connections
  • Corroded wires
  • Insufficient electrical supply

Compressor overloads can be prevented by doing just a few things:

Don’t neglect maintenance. Change out your air filter every three months at a minimum, more frequently if you have an active household. Be sure there is no debris by your outside unit.

Find a trusted HVAC professional. Finding someone you can trust will help you extend the life of your compressor by making sure all equipment is installed correctly and operating at peak capacity.

Consider a compressor overload protector. This special sensor monitors temperatures and shuts down the compressor temporarily to prevent it from overheating. By turning off your system, it allows the compressor to cool and prevent overload before it happens and causes costly repairs.

If your compressor is overheated, it’s essential to find the root cause and repair it as quickly as possible. We can help.
