There are many reasons why your AC system freezes up.
Checking the air filter isn’t clogged and airflow isn’t lowered are the only things you can safely handle on your own. If you need to replace the filter, you can accelerate the melting process by turning off the unit and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.
After the ice is gone, move the temp back to normal. If your system freezes again, call Service Experts Heating & Air Conditioning to repair the issue.
Here are a few other reasons why your system may be freezing up.
Low refrigerant—Freezing up could be created by a refrigerant leak.
What leads to a leak?
- Fragile solder joints
- Grating from piping jarring against an object
- Broken valves
- Loose fittings
How long your system has been running and the location of the leak determine whether you should repair or replace your AC system.
Filthy evaporator coil—Throughout the seasons, the evaporator coil gets dirty and creates problems resembling a dusty filter. You’ll progressively get lower airflow until your unit freezes or stops cooling. You’ll need to get in touch with Service Experts Heating & Air Conditioning to take care of the problem.
Malfunctioning blower motor or relay—A blower motor running at an inaccurate speed or not working at all can result in freezing. It can also be intermittent, starting at top speed and going slower after it gets too hot. Or a relay can force it to work one time and not the subsequent time. In either situation, you will need to contact Service Experts Heating & Air Conditioning to correct the problem.
Requesting yearly AC maintenance could help you bypass this malfunction. Our Experts will fully examine and clean your unit, which typically allows us to find small problems before they cause huge issues.
