Why is my AC system freezing up?

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

Double-checking the air filter isn’t clogged 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 defrosting process by switching off the unit and turning on 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 equipment freezes again, contact Rob's Albertan Service Experts to take care of the issue.

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

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

What causes a leak?

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

How long your unit has been working and the area 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 slowly get lower airflow until your equipment freezes or stops cooling. You’ll need to call Rob's Albertan Service Experts to repair the malfunction.

Broken blower motor or relay—A blower motor running at an inaccurate speed or not turning on at all can lead to freezing. It might also be irregular, 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 fix the issue.

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