There are many reasons why your AC system freezes up in Charlotte. Almost all of them frequently call for skilled AC repair.
Double-checking the air filter isn’t dusty and airflow isn’t lowered are the only work you can safely fix without professional help. If you need to install a new the filter, you can speed up the defrosting process by disabling the unit and switching on the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.
After the ice melts, turn the temperature back to normal. If your system freezes repeatedly, get in touch with Komfort Air to repair the problem.
Here are a few other reasons why your equipment could be freezing up.
Insufficient refrigerant—Freezing up may be created by a refrigerant leak.
What causes a leak?
- Weak solder joints
- Grating from piping rubbing against an object
- Cracked valves
- Unsecured fittings
How long your unit 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 becomes dirty and causes issues much like a dusty filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to contact Komfort Air to repair the malfunction.
Broken blower motor or relay—A blower motor working at an incorrect speed or not working at all can result in freezing. It might also be irregular, starting at maximum speed and slowing down after it gets too hot. Or a relay could force it to work one time and not the subsequent time. In either situation, you will need to contact Komfort Air to fix the trouble.
Booking annual AC maintenance or heat pump maintenance can help you avoid this malfunction. Our pros will meticulously inspect and clean your unit, which frequently allows us to notice little troubles before they become major problems.
