Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Champaign. Nearly all of them typically call for professional AC repair.

Checking the air filter is clean and airflow isn’t restricted are the only tasks you can safely handle without professional help. If you need to replace the filter, you can hasten the defrosting process by switching off the unit and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.

After the ice melts, turn the temperature back to normal. If your system freezes repeatedly, get in touch with Chief/Bauer Service Experts to fix the malfunction.

Here are several other reasons why your unit could be freezing up.

Insufficient refrigerant—Freezing up could be caused by a refrigerant leak.

What leads to a leak?

  • Weakened solder joints
  • Grating from piping rubbing against an object
  • Broken valves
  • Slack fittings

How long your equipment has been installed and the spot of the leak play a part in whether you should repair or replace your AC system.

Filthy evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and causes issues much like a dirty filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to contact Chief/Bauer Service Experts to take care of the problem.

Defective blower motor or relay—A blower motor working at an inaccurate speed or not working at all can result in freezing. It can also be intermittent, running at top speed and going slower after it gets warm. Or a relay might cause it to work one time and not the following time. In either case, you will need to get in touch with Chief/Bauer Service Experts to repair the trouble.

Requesting yearly AC maintenance or heat pump maintenance may help you avoid this issue. Our professionals will comprehensively examine and clean your unit, which typically allows us to discover small problems before they cause large issues.
