There are lots of reasons why your AC system freezes up in Toronto. Most all of them frequently need professional AC repair.
Checking the air filter isn’t dusty and airflow isn’t restricted are the only work you can safely handle on your own. If you need to put in a new the filter, you can accelerate the defrosting process by disabling 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, move settings back to normal. If your equipment freezes repeatedly, contact Service Experts Commercial HVAC to fix the problem.
Here are a couple other other reasons why your system might be freezing up.
Insufficient refrigerant—A frozen system may be created by a refrigerant leak.
What creates a leak?
- Weakened solder joints
- Resistance from piping jarring against other components
- Ruptured valves
- Slack fittings
How long your system has been working and the spot of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—Throughout the seasons, the evaporator coil gets dirty and creates issues resembling a dusty filter. You’ll gradually lose airflow until your system freezes or quits cooling. You’ll need to call Service Experts Commercial HVAC to fix the problem.
Broken blower motor or relay—A blower motor working at an incorrect speed or not running at all can result in freezing. It may also be irregular, going at top speed and slowing down after it gets warm. Or a relay could make it run one time and not the next. In either case, you will need to contact Service Experts Commercial HVAC to repair the trouble.
