There are a lot of reasons why your AC system freezes up.
Checking the air filter isn’t dusty and airflow isn’t decreased are the only tasks you can safely take care of on your own. If you need to put in a new the filter, you can accelerate the defrosting process by disabling the equipment 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 melts, turn the temperature back to normal. If your system freezes again, contact Niagara Home Services by Enercare to take care of the issue.
Here are a couple other other reasons why your equipment might be freezing up.
Not enough refrigerant—Freezing can be a result of a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Grating from piping rubbing against an object
- Broken valves
- Loose fittings
How long your equipment has been running and the location of the leak determine whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil gets dirty and creates troubles much like a dusty filter. You’ll gradually lose airflow until your unit freezes or quits cooling. You’ll need to get in touch with Niagara Home Services by Enercare to repair the issue.
Malfunctioning blower motor or relay—A blower motor running at the wrong speed or not turning on at all can lead to freezing. It may also be irregular, going at maximum speed and slowing down after it gets warm. Or a relay might make it run one time and not the subsequent time. In either case, you will need to contact Niagara Home Services by Enercare to repair the issue.
