There are many reasons why your AC system freezes up in Tempe. Most all of them usually require skilled AC repair.
Checking the air filter isn’t clogged and airflow isn’t lowered are the only tasks you can safely take care of yourself. If you need to replace the filter, you can hasten the thawing process by turning off the unit and using the fan. If you have a heat pump, you can switch it to heat mode until the ice has disappeared.
After the ice disappears, turn the temperature back to normal. If your unit freezes repeatedly, get in touch with Bob Brown Service Experts to correct the issue.
Here are a couple other other reasons why your equipment might be freezing up.
Not enough refrigerant—Freezing may be created by a refrigerant leak.
What creates a leak?
- Fragile solder joints
- Friction from piping rubbing against other parts
- Broken valves
- Loose fittings
How long your system has been running and the spot of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil attracts dirt and causes problems much like a clogged filter. You’ll gradually get lower airflow until your equipment freezes or quits cooling. You’ll need to get in touch with Bob Brown Service Experts to take care of the problem.
Defective blower motor or relay—A blower motor running at the wrong speed or not working at all can create freezing. It can also be sporadic, starting at full speed and going slower after it gets too hot. Or a relay might force it to work one time and not the next. In either case, you will need to contact Bob Brown Service Experts to correct the issue.
Requesting annual AC maintenance or heat pump maintenance could help you bypass this problem. Our technicians will fully inspect and clean your unit, which typically allows us to spot small problems before they cause large troubles.
