Why is my AC system freezing up?
There are lots of reasons why your AC system freezes up.
Checking the air filter isn’t dirty and airflow isn’t restricted are the only tasks you can safely take care of alone. If you need to install a new the filter, you can hasten the thawing process by disabling the unit and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.
After the ice disappears, move settings back to normal. If your equipment freezes a second time, get in touch with Strand Brothers Service Experts to take care of the issue.
Here are several other reasons why your unit might be freezing up.
Low refrigerant—Freezing up may be caused by a refrigerant leak.
What creates a leak?
- Fragile solder joints
- Resistance from piping jarring against other parts
- Broken valves
- Unsecured fittings
How long your system has been running and the area of the leak play a part in whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil gets dirty and creates issues much like a clogged filter. You’ll progressively get lower airflow until your system freezes or quits cooling. You’ll need to get in touch with Strand Brothers Service Experts to fix the problem.
Broken blower motor or relay—A blower motor going at the wrong speed or not running at all can result in freezing. It can also be sporadic, starting at top speed and going slower after it gets too hot. Or a relay might make it work one time and not the following time. In either situation, you will need to contact Strand Brothers Service Experts to repair the problem.
Requesting yearly AC maintenance can help you skip this issue. Our technicians will fully inspect and clean your unit, which usually allows us to discover little problems before they become major troubles.
