Why is my AC system freezing up?

There are a lot of reasons why your AC system freezes up in Boise. Almost all of them frequently need skilled AC repair.

Making sure the air filter is clean and airflow isn’t decreased are the only work you can safely fix without professional help. If you need to replace the filter, you can speed up the thawing process by turning off the system and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.

After the ice is gone, switch settings back to normal. If your system freezes a second time, get in touch with TML Service Experts to correct the issue.

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

Low refrigerant—Freezing may be caused by a refrigerant leak.

What causes a leak?

  • Weak solder joints
  • Resistance from piping jarring against other components
  • Ruptured valves
  • Loose fittings

How long your equipment 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 becomes dirty and leads to troubles similar to a clogged filter. You’ll gradually receive lower airflow until your equipment freezes or stops cooling. You’ll need to call TML Service Experts to repair the issue.

Malfunctioning blower motor or relay—A blower motor working at the wrong speed or not running at all can cause freezing. It might also be irregular, starting at full speed and slowing down after it gets warm. Or a relay could make it work one time and not the next. In either situation, you will need to contact TML Service Experts to repair the trouble.

Requesting regular AC maintenance or heat pump maintenance could help you avoid this problem. Our Experts will thoroughly examine and clean your equipment, which frequently allows us to spot small troubles before they cause large issues.
