There are a lot of reasons why your AC system freezes up in Knoxville. Most all of them frequently require skilled AC repair.
Making sure the air filter isn’t dusty and airflow isn’t lowered 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 switch 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 unit could be freezing up.
Low refrigerant—Freezing can be created by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Resistance from piping vibrating 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.
Dusty evaporator coil—Over time, the evaporator coil attracts dirt and leads to issues similar to a dirty filter. You’ll gradually get lower airflow until your equipment freezes or quits 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 working at all can lead to freezing. It may also be sporadic, starting at full speed and slowing down after it gets warm. Or a relay could make it work one time and not the subsequent time. In either case, you will need to call R & M Climate Control Service Experts to correct the trouble.
Scheduling annual AC maintenance or heat pump maintenance could help you skip this issue. Our technicians will fully examine and clean your equipment, which typically allows us to notice small troubles before they become large issues.
