There are a lot of reasons why your AC system freezes up.
Checking the air filter isn’t dusty and airflow isn’t decreased are the only tasks you can safely fix alone. If you need to put in a new the filter, you can hasten the defrosting process by switching off the equipment 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 disappears, turn settings back to normal. If your system freezes repeatedly, contact Donelson Air Service Experts to repair the malfunction.
Here are several other reasons why your unit might be freezing up.
Not enough refrigerant—A frozen system could be created by a refrigerant leak.
What creates a leak?
- Fragile solder joints
- Resistance from piping rubbing against an object
- Broken valves
- Unsecured fittings
How long your equipment has been installed and the spot of the leak play a role in whether you should repair or replace your AC system.
Dusty evaporator coil—Throughout the seasons, the evaporator coil becomes dirty and causes troubles much like a dusty filter. You’ll gradually get lower airflow until your unit freezes or halts cooling. You’ll need to get in touch with Donelson Air Service Experts to fix the problem.
Malfunctioning blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can lead to freezing. It may also be sporadic, running at maximum speed and decelerating after it heats up. Or a relay could cause it to run one time and not the subsequent time. In either state, you will need to get in touch with Donelson Air Service Experts to fix the issue.
Requesting regular AC maintenance can help you avoid this malfunction. Our professionals will thoroughly check and clean your unit, which typically allows us to pinpoint minor troubles before they turn into huge issues.
