Why is my AC system freezing up?

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

Double-checking the air filter isn’t clogged and airflow isn’t lowered are the only things you can safely handle without professional help. If you need to replace the filter, you can accelerate the thawing 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 is gone.

After the ice melts, move the temp back to normal. If your unit freezes repeatedly, contact Calverley Service Experts to correct the malfunction.

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

Low refrigerant—Freezing up can be caused by a refrigerant leak.

What leads to a leak?

  • Weakened solder joints
  • Resistance from piping jarring against other parts
  • Broken valves
  • Slack fittings

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

Filthy evaporator coil—As time passes, the evaporator coil gets dirty and creates issues similar to a dusty filter. You’ll slowly receive lower airflow until your unit freezes or quits cooling. You’ll need to get in touch with Calverley Service Experts to repair the malfunction.

Broken blower motor or relay—A blower motor going at the wrong speed or not turning on at all can create freezing. It might also be sporadic, running at full speed and decelerating after it heats up. Or a relay could cause it to run one time and not the next. In either state, you will need to contact Calverley Service Experts to repair the trouble.

Scheduling annual AC maintenance can help you bypass this malfunction. Our techs will comprehensively inspect and clean your equipment, which usually allows us to pinpoint minor troubles before they become huge issues.
