Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Winnipeg. Most all of them usually require professional AC repair.

Double-checking the air filter isn’t dusty and airflow isn’t lowered are the only tasks you can safely handle without professional help. If you need to put in a new the filter, you can speed up the melting process by turning off the system and using the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.

After the ice melts, switch settings back to normal. If your unit freezes repeatedly, call Winnipeg Supply Service Experts to repair the issue.

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

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

What leads to a leak?

  • Weakened solder joints
  • Grating from piping jarring against something
  • Ruptured valves
  • Loose fittings

How long your unit has been running 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 resembling a dusty filter. You’ll slowly get lower airflow until your system freezes or stops cooling. You’ll need to contact Winnipeg Supply Service Experts to take care of the problem.

Defective blower motor or relay—A blower motor running at an inaccurate speed or not running at all can result in freezing. It might also be irregular, starting at top speed and slowing down after it gets warm. Or a relay can cause it to start one time and not the next. In either situation, you will need to call Winnipeg Supply Service Experts to fix the problem.

Booking annual AC maintenance or heat pump maintenance may help you avoid this malfunction. Our professionals will thoroughly examine and clean your system, which often allows us to notice small issues before they turn into major issues.
