There are lots of reasons why your AC system freezes up.
Making sure the air filter isn’t clogged and airflow isn’t decreased are the only work you can safely fix without professional help. If you need to replace the filter, you can speed up the thawing 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 is gone, switch settings back to normal. If your system freezes repeatedly, call TML Service Experts to correct the issue.
Here are a couple other other reasons why your unit might be freezing up.
Low refrigerant—Freezing may be caused by a refrigerant leak.
What creates a leak?
- Weak solder joints
- Grating from piping jarring against other components
- Cracked valves
- Loose fittings
How long your unit has been running 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 becomes dirty and creates issues similar to a clogged filter. You’ll gradually get lower airflow until your equipment freezes or stops cooling. You’ll need to get in touch with TML Service Experts to take care of the issue.
Malfunctioning blower motor or relay—A blower motor working at the wrong speed or not running at all can lead to freezing. It can also be intermittent, starting at full speed and slowing down after it gets warm. Or a relay could force it to work one time and not the following time. In either situation, you will need to contact TML Service Experts to repair the issue.
Requesting regular AC maintenance could help you avoid this problem. Our techs will meticulously check and clean your equipment, which frequently allows us to spot small troubles before they turn into large issues.
