Why is my AC system freezing up?

There are many reasons why your AC system freezes up.

Checking the air filter isn’t clogged and airflow isn’t decreased are the only things you can safely take care of yourself. If you need to put in a new the filter, you can speed up the melting process by switching off the system and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.

After the ice melts, turn the temp back to normal. If your equipment freezes a second time, get in touch with Service Experts Heating & Air Conditioning to fix the problem.

Here are a few other reasons why your unit might be freezing up.

Not enough refrigerant—A frozen system may be created by a refrigerant leak.

What causes a leak?

  • Weak solder joints
  • Friction from piping rubbing against an object
  • Broken valves
  • Loose fittings

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

Dirty evaporator coil—Throughout the seasons, the evaporator coil becomes dirty and causes problems resembling a dusty filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to contact Service Experts Heating & Air Conditioning to repair the malfunction.

Broken blower motor or relay—A blower motor going at an incorrect speed or not working at all can result in freezing. It can also be irregular, going at top speed and decelerating after it gets warm. Or a relay might cause it to run one time and not the subsequent time. In either state, you will need to contact Service Experts Heating & Air Conditioning to repair the trouble.
