There are a lot of reasons why your AC system freezes up.
Double-checking the air filter isn’t dirty and airflow isn’t lowered are the only things you can safely take care of yourself. If you need to replace the filter, you can speed up the melting process by turning off the system and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice is gone.
After the ice disappears, turn settings back to normal. If your system freezes repeatedly, get in touch with Service Experts Heating & Air Conditioning to fix the problem.
Here are a few other reasons why your unit may be freezing up.
Insufficient refrigerant—Freezing up could be created by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Grating from piping rubbing against other parts
- Broken valves
- Unsecured fittings
How long your equipment has been running and the location of the leak play a part in whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil becomes dirty and causes problems resembling a dusty filter. You’ll gradually get lower airflow until your equipment freezes or stops cooling. You’ll need to get in touch with Service Experts Heating & Air Conditioning to fix the problem.
Broken blower motor or relay—A blower motor going at the wrong speed or not turning on at all can create freezing. It could also be irregular, going at full speed and decelerating after it heats up. Or a relay may cause it to work one time and not the next. In either case, you will need to get in touch with Service Experts Heating & Air Conditioning to correct the problem.
