There are many reasons why your AC system freezes up in Winnipeg. Nearly all of them usually require skilled AC repair.
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 install a new the filter, you can speed up the defrosting process by turning off the system and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.
After the ice melts, switch settings back to normal. If your equipment freezes a second time, call Winnipeg Supply Service Experts to repair the malfunction.
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?
- Fragile solder joints
- Resistance from piping jarring against something
- Ruptured valves
- Loose fittings
How long your equipment 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 troubles much like 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 repair the problem.
Defective blower motor or relay—A blower motor running at an incorrect speed or not running at all can result in freezing. It can also be irregular, starting at maximum speed and slowing down after it gets too hot. Or a relay can cause it to start one time and not the next. In either state, you will need to call Winnipeg Supply Service Experts to repair the problem.
Requesting annual AC maintenance or heat pump maintenance can help you avoid this issue. Our professionals will meticulously check and clean your system, which typically allows us to notice small issues before they cause huge issues.
