There are many reasons why your AC system freezes up.
Double-checking the air filter isn’t clogged and airflow isn’t decreased are the only things you can safely take care of yourself. If you need to install a new the filter, you can accelerate the thawing process by disabling the equipment and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.
After the ice melts, turn settings back to normal. If your unit freezes repeatedly, contact Teays Valley Service Experts to fix the malfunction.
Here are several other reasons why your system could be freezing up.
Insufficient refrigerant—Freezing may be created by a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Friction from piping vibrating against something
- Ruptured valves
- Loose fittings
How long your system has been running and the location of the leak play a part in whether you should repair or replace your AC system.
Dusty evaporator coil—As time passes, the evaporator coil becomes dirty and leads to issues similar to a dirty filter. You’ll slowly lose airflow until your system freezes or quits cooling. You’ll need to contact Teays Valley Service Experts to take care of the malfunction.
Broken blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can lead to freezing. It can also be intermittent, going at top speed and decelerating after it gets too hot. Or a relay might force it to work one time and not the next. In either case, you will need to contact Teays Valley Service Experts to fix the problem.
