Why is my AC system freezing up?

There are lots of reasons why your AC system freezes up in Calgary. Almost all of them frequently need pro AC repair.

Double-checking the air filter isn’t clogged and airflow isn’t restricted are the only work you can safely handle yourself. If you need to replace the filter, you can hasten the defrosting process by switching off the system 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 disappears, switch the temperature back to normal. If your equipment freezes repeatedly, get in touch with A1 Chesney Service Experts to fix the malfunction.

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

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

What leads to a leak?

  • Fragile solder joints
  • Resistance from piping rubbing against other components
  • Ruptured valves
  • Loose fittings

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

Dusty evaporator coil—Over time, the evaporator coil attracts dirt and leads to troubles similar to a clogged filter. You’ll gradually get lower airflow until your equipment freezes or stops cooling. You’ll need to call A1 Chesney Service Experts to fix the issue.

Broken blower motor or relay—A blower motor running at an incorrect speed or not working at all can create freezing. It might also be sporadic, running at full speed and going slower after it gets warm. Or a relay might force it to start one time and not the subsequent time. In either state, you will need to call A1 Chesney Service Experts to repair the issue.

Requesting regular AC maintenance or heat pump maintenance could help you avoid this malfunction. Our technicians will meticulously examine and clean your system, which frequently allows us to pinpoint minor problems before they become large problems.
