Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Making sure the air filter isn’t clogged and airflow isn’t restricted are the only tasks you can safely take care of yourself. If you need to put in a new the filter, you can accelerate the melting process by switching off the equipment and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice disappears, turn settings back to normal. If your equipment freezes again, contact Service Experts Heating & Air Conditioning to fix the issue.

Here are several other reasons why your system might be freezing up.

Low refrigerant—A frozen system could be a result of a refrigerant leak.

What leads to a leak?

  • Weak solder joints
  • Grating from piping rubbing against other components
  • Broken valves
  • Unsecured fittings

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

Filthy evaporator coil—As time passes, the evaporator coil gets dirty and creates issues resembling a clogged filter. You’ll progressively get lower airflow until your system freezes or quits cooling. You’ll need to call Service Experts Heating & Air Conditioning to take care of the problem.

Broken blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can lead to freezing. It may also be sporadic, running at top speed and going slower after it gets warm. Or a relay can force it to run one time and not the next. In either situation, you will need to call Service Experts Heating & Air Conditioning to repair the trouble.
