There are a lot of reasons why your AC system freezes up.
Checking the air filter isn’t dirty and airflow isn’t restricted are the only things you can safely handle on your own. If you need to replace the filter, you can accelerate the defrosting process by switching off the equipment and using the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.
After the ice disappears, move the temp back to normal. If your system freezes a second time, call Peitz Service Experts to repair the problem.
Here are several other reasons why your unit may be freezing up.
Not enough refrigerant—Freezing up could be caused by a refrigerant leak.
What creates a leak?
- Weak solder joints
- Resistance from piping jarring against an object
- Ruptured valves
- Unsecured fittings
How long your system has been installed and the area of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—Throughout the seasons, the evaporator coil gets dirty and causes troubles resembling a clogged filter. You’ll gradually receive lower airflow until your system freezes or halts cooling. You’ll need to call Peitz Service Experts to repair the problem.
Broken blower motor or relay—A blower motor going at the wrong speed or not running at all can create freezing. It may also be intermittent, going at full speed and slowing down after it heats up. Or a relay may force it to start one time and not the following time. In either case, you will need to contact Peitz Service Experts to correct the trouble.
