Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up.

Double-checking the air filter is clean and airflow isn’t decreased are the only work you can safely handle alone. If you need to put in a new the filter, you can accelerate the thawing process by turning off the unit and switching on the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.

After the ice disappears, turn the temp back to normal. If your system freezes repeatedly, call Golden Seal Service Experts to fix the problem.

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

Low refrigerant—Freezing could be a result of a refrigerant leak.

What creates a leak?

  • Weakened solder joints
  • Friction from piping vibrating against other components
  • Broken valves
  • Unsecured fittings

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

Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and causes troubles resembling a dirty filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to contact Golden Seal Service Experts to take care of the issue.

Broken blower motor or relay—A blower motor going at the wrong speed or not turning on at all can lead to freezing. It might also be irregular, starting at top speed and going slower after it gets warm. Or a relay could make it work one time and not the following time. In either state, you will need to contact Golden Seal Service Experts to fix the issue.

Requesting annual AC maintenance might help you skip this issue. Our professionals will meticulously check and clean your unit, which usually allows us to notice small issues before they cause huge problems.
