Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up.

Checking the air filter isn’t dusty and airflow isn’t restricted are the only things you can safely fix alone. If you need to install a new the filter, you can speed up the defrosting process by turning off the system and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.

After the ice is gone, move settings back to normal. If your equipment freezes repeatedly, call Sunbeam Service Experts to repair the problem.

Here are a couple other other reasons why your equipment may be freezing up.

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

What leads to a leak?

  • Weak solder joints
  • Resistance from piping vibrating against other components
  • Ruptured valves
  • Slack fittings

How long your equipment has been working and the location 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 causes troubles resembling a clogged filter. You’ll slowly lose airflow until your unit freezes or quits cooling. You’ll need to contact Sunbeam Service Experts to repair the problem.

Defective blower motor or relay—A blower motor going at an inaccurate speed or not working at all can cause freezing. It might also be intermittent, going at full speed and slowing down after it heats up. Or a relay might cause it to run one time and not the following time. In either state, you will need to contact Sunbeam Service Experts to correct the trouble.

Booking yearly AC maintenance could help you avoid this problem. Our Experts will comprehensively check and clean your unit, which frequently allows us to locate small troubles before they become large troubles.
