There are many reasons why your AC system freezes up.
Double-checking the air filter is clean and airflow isn’t restricted are the only tasks you can safely handle without professional help. If you need to replace the filter, you can hasten the melting process by switching off the equipment and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice is gone.
After the ice disappears, move the temperature back to normal. If your system freezes a second time, call Chief/Bauer Service Experts to fix the malfunction.
Here are a couple other other reasons why your unit could be freezing up.
Not enough refrigerant—A frozen system may be caused by a refrigerant leak.
What leads to a leak?
- Weakened solder joints
- Resistance from piping vibrating against other components
- Broken valves
- Unsecured fittings
How long your unit has been installed and the spot of the leak play a part in whether you should repair or replace your AC system.
Dusty evaporator coil—Throughout the seasons, the evaporator coil gets dirty and causes troubles much like a dirty filter. You’ll gradually lose airflow until your system freezes or halts cooling. You’ll need to contact Chief/Bauer Service Experts to take care of the problem.
Defective blower motor or relay—A blower motor working at an inaccurate speed or not working at all can result in freezing. It can also be irregular, going at top speed and going slower after it gets warm. Or a relay might cause it to work one time and not the next. In either case, you will need to call Chief/Bauer Service Experts to fix the issue.
