There are many reasons why your AC system freezes up.
Checking the air filter is clean and airflow isn’t restricted are the only tasks you can safely fix yourself. If you need to replace the filter, you can hasten the melting process by turning off the equipment and using the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.
After the ice melts, move settings back to normal. If your equipment freezes a second time, get in touch with Service Experts Heating & Air Conditioning to take care of the malfunction.
Here are a couple other other reasons why your equipment could be freezing up.
Low refrigerant—Freezing can be created by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Friction from piping rubbing against other parts
- Cracked valves
- Slack fittings
How long your system has been installed and the location of the leak play a role in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil attracts dirt and leads to problems similar to a dirty filter. You’ll slowly receive lower airflow until your equipment freezes or quits cooling. You’ll need to call Service Experts Heating & Air Conditioning to fix the malfunction.
Broken blower motor or relay—A blower motor running at an incorrect speed or not running at all can result in freezing. It may also be irregular, going at top speed and slowing down after it heats up. Or a relay might cause it to work one time and not the subsequent time. In either state, you will need to contact Service Experts Heating & Air Conditioning to correct the issue.
Scheduling yearly AC maintenance can help you skip this malfunction. Our professionals will meticulously check and clean your equipment, which typically allows us to find minor issues before they become major issues.
