Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Edmonton. Nearly all of them typically require skilled AC repair.

Double-checking the air filter is clean and airflow isn’t restricted are the only things you can safely take care of on your own. If you need to install a new the filter, you can hasten the melting process by disabling the unit and using the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.

After the ice is gone, turn settings back to normal. If your unit freezes again, contact Rob's Albertan Service Experts to take care of the malfunction.

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

Insufficient refrigerant—A frozen system may be a result of a refrigerant leak.

What creates a leak?

  • Weak solder joints
  • Friction from piping jarring against an object
  • Ruptured valves
  • Unsecured fittings

How long your equipment has been running and the spot of the leak determine whether you should repair or replace your AC system.

Dirty evaporator coil—Over time, the evaporator coil gets dirty and causes issues similar to a clogged filter. You’ll progressively get lower airflow until your unit freezes or stops cooling. You’ll need to get in touch with Rob's Albertan Service Experts to take care of the issue.

Broken blower motor or relay—A blower motor running at an incorrect speed or not working at all can lead to freezing. It might also be intermittent, starting at full speed and going slower after it heats up. Or a relay can make it start one time and not the subsequent time. In either situation, you will need to get in touch with Rob's Albertan Service Experts to repair the issue.

Scheduling yearly AC maintenance or heat pump maintenance might help you avoid this malfunction. Our technicians will comprehensively inspect and clean your system, which often allows us to locate little problems before they cause major issues.
