There are lots of reasons why your AC system freezes up.
Double-checking the air filter isn’t dirty and airflow isn’t restricted are the only work you can safely fix alone. If you need to put in a new the filter, you can accelerate the melting process by switching off the equipment and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.
After the ice melts, turn the temperature back to normal. If your system freezes again, call Service Experts Heating & Air Conditioning to take care of the malfunction.
Here are a few other reasons why your system may be freezing up.
Not enough refrigerant—A frozen system could be a result of a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Grating from piping vibrating against something
- Cracked valves
- Loose fittings
How long your equipment has been installed and the location of the leak determine whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil attracts dirt and leads to problems resembling a dirty filter. You’ll slowly receive lower airflow until your unit freezes or stops cooling. You’ll need to call Service Experts Heating & Air Conditioning to fix the malfunction.
Malfunctioning blower motor or relay—A blower motor going at an incorrect speed or not running at all can create freezing. It could also be intermittent, going at maximum speed and going slower after it gets warm. Or a relay may make it work one time and not the subsequent time. In either situation, you will need to contact Service Experts Heating & Air Conditioning to correct the trouble.
