There are lots of reasons why your AC system freezes up.
Making sure the air filter isn’t dirty and airflow isn’t restricted are the only things you can safely fix alone. If you need to install a new the filter, you can speed up the melting process by turning off the system and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.
After the ice disappears, move the temp back to normal. If your unit freezes a second time, call Strogen's Service Experts to correct the problem.
Here are a couple other other reasons why your equipment could be freezing up.
Not enough refrigerant—Freezing could be caused by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Resistance from piping vibrating against something
- Cracked valves
- Unsecured fittings
How long your unit has been installed and the location of the leak play a part in whether you should repair or replace your AC system.
Dusty evaporator coil—Throughout the seasons, the evaporator coil becomes dirty and creates troubles resembling a clogged filter. You’ll gradually get lower airflow until your equipment freezes or stops cooling. You’ll need to contact Strogen's Service Experts to take care of the malfunction.
Defective blower motor or relay—A blower motor going at the wrong speed or not turning on at all can cause freezing. It might also be intermittent, going at maximum speed and slowing down after it gets warm. Or a relay might cause it to work one time and not the following time. In either case, you will need to contact Strogen's Service Experts to repair the issue.
