Why is my AC system freezing up?

There are many reasons why your AC system freezes up in the Wasatch Front region. Nearly all of them typically require pro AC repair.

Making sure the air filter is clean and airflow isn’t lowered are the only things you can safely handle yourself. If you need to install a new the filter, you can speed up the melting process by disabling the system and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.

After the ice disappears, move the temp back to normal. If your equipment freezes repeatedly, get in touch with Barlow Service Experts to correct the problem.

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

Insufficient refrigerant—Freezing can be created by a refrigerant leak.

What leads to a leak?

  • Fragile solder joints
  • Friction from piping rubbing against something
  • Ruptured valves
  • Unsecured fittings

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

Dirty evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and creates problems resembling a clogged filter. You’ll gradually get lower airflow until your system freezes or halts cooling. You’ll need to get in touch with Barlow Service Experts to repair the issue.

Defective blower motor or relay—A blower motor running at the wrong speed or not working at all can lead to freezing. It might also be sporadic, running at maximum speed and slowing down after it gets too hot. Or a relay may make it start one time and not the subsequent time. In either situation, you will need to contact Barlow Service Experts to repair the problem.

Requesting regular AC maintenance or heat pump maintenance may help you avoid this problem. Our techs will comprehensively examine and clean your equipment, which usually allows us to locate small troubles before they turn into large issues.
