There are a lot of reasons why your AC system freezes up.
Checking the air filter is clean and airflow isn’t decreased are the only tasks you can safely handle alone. If you need to put in a new the filter, you can speed up the melting process by disabling the unit and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.
After the ice is gone, switch the temp back to normal. If your system freezes a second time, contact Strand Brothers Service Experts to correct the problem.
Here are a couple other other reasons why your equipment might be freezing up.
Low refrigerant—Freezing up may be a result of a refrigerant leak.
What creates a leak?
- Weakened solder joints
- Grating from piping rubbing against other components
- Broken valves
- Slack fittings
How long your unit has been working and the location of the leak determine whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil gets dirty and leads to issues much like a dusty filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to call Strand Brothers Service Experts to repair the malfunction.
Broken blower motor or relay—A blower motor running at an incorrect speed or not working at all can create freezing. It can also be irregular, running at full speed and decelerating after it heats up. Or a relay could cause it to work one time and not the next. In either case, you will need to call Strand Brothers Service Experts to repair the problem.
Booking annual AC maintenance might help you bypass this malfunction. Our Experts will fully examine and clean your unit, which usually allows us to notice minor problems before they turn into huge troubles.
