Why is my AC system freezing up?
There are a lot of reasons why your AC system freezes up.
Checking the air filter isn’t clogged and airflow isn’t decreased are the only things you can safely fix yourself. If you need to install a new the filter, you can hasten the melting process by turning off the equipment and switching on the fan. If you have a heat pump, you can switch it to heat mode until the ice is gone.
After the ice is gone, switch the temp back to normal. If your equipment freezes repeatedly, call Service Experts Heating & Air Conditioning to correct the problem.
Here are a couple other other reasons why your system may be freezing up.
Insufficient refrigerant—Freezing may be caused by a refrigerant leak.
What causes a leak?
- Weak solder joints
- Friction from piping jarring against other components
- Broken valves
- Unsecured fittings
How long your system has been working and the spot of the leak determine whether you should repair or replace your AC system.
Dirty evaporator coil—Throughout the seasons, the evaporator coil becomes dirty and creates troubles similar to a dirty filter. You’ll gradually receive lower airflow until your system freezes or stops cooling. You’ll need to call Service Experts Heating & Air Conditioning to repair the malfunction.
Broken blower motor or relay—A blower motor running at an incorrect speed or not working at all can result in freezing. It may also be sporadic, going at top speed and decelerating after it gets warm. Or a relay may make it start one time and not the next. In either state, you will need to call Service Experts Heating & Air Conditioning to repair the issue.
