There are lots of reasons why your AC system freezes up.
Making sure the air filter is clean and airflow isn’t decreased are the only work you can safely handle alone. If you need to put in a new the filter, you can hasten the thawing process by switching off the unit and turning 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, move the temp back to normal. If your unit freezes again, contact Robinson Service Experts to fix the issue.
Here are a couple other other reasons why your system could be freezing up.
Insufficient refrigerant—Freezing could be created by a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Friction from piping rubbing against an object
- Cracked valves
- Loose fittings
How long your equipment has been installed 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 issues resembling a dirty filter. You’ll slowly get lower airflow until your unit freezes or halts cooling. You’ll need to call Robinson Service Experts to take care of the problem.
Defective blower motor or relay—A blower motor going at an incorrect speed or not working at all can result in freezing. It may also be sporadic, starting at full speed and slowing down after it gets too hot. Or a relay can force it to start one time and not the subsequent time. In either situation, you will need to call Robinson Service Experts to correct the trouble.
