There are lots of reasons why your AC system freezes up.
Making sure the air filter isn’t dusty and airflow isn’t decreased are the only work you can safely fix on your own. If you need to put in a new the filter, you can accelerate the thawing process by turning off the equipment and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.
After the ice is gone, move the temp back to normal. If your unit freezes a second time, contact R & M Climate Control Service Experts to correct the issue.
Here are a few other reasons why your equipment could be freezing up.
Low refrigerant—Freezing can be a result of a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Resistance from piping rubbing against something
- Ruptured valves
- Loose fittings
How long your system has been working and the spot of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil gets dirty and creates troubles similar to a dirty filter. You’ll gradually get lower airflow until your unit freezes or halts cooling. You’ll need to call R & M Climate Control Service Experts to fix the problem.
Broken blower motor or relay—A blower motor running at the wrong speed or not turning on at all can cause freezing. It may also be sporadic, starting at full speed and slowing down after it gets too hot. Or a relay could force it to work one time and not the subsequent time. In either case, you will need to get in touch with R & M Climate Control Service Experts to correct the trouble.
Scheduling annual AC maintenance could help you bypass this malfunction. Our technicians will fully examine and clean your unit, which often allows us to catch small troubles before they become large issues.
