There are a lot of reasons why your AC system freezes up.
Double-checking the air filter isn’t clogged and airflow isn’t decreased are the only tasks you can safely fix on your own. If you need to replace the filter, you can accelerate the thawing process by disabling the system 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 is gone, move the temperature back to normal. If your unit freezes again, contact Air Engineers Service Experts to repair the malfunction.
Here are a couple other other reasons why your system may be freezing up.
Not enough refrigerant—Freezing may be a result of a refrigerant leak.
What leads to a leak?
- Weak solder joints
- Friction from piping jarring against something
- Ruptured valves
- Slack 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.
Filthy evaporator coil—Throughout the seasons, the evaporator coil gets dirty and causes troubles resembling a dusty filter. You’ll gradually receive lower airflow until your equipment freezes or stops cooling. You’ll need to contact Air Engineers Service Experts to fix the malfunction.
Malfunctioning blower motor or relay—A blower motor running at the wrong speed or not working at all can create freezing. It may also be sporadic, running at full speed and decelerating after it heats up. Or a relay could force it to work one time and not the next. In either state, you will need to contact Air Engineers Service Experts to correct the problem.
Requesting regular AC maintenance can help you bypass this problem. Our technicians will meticulously check and clean your equipment, which typically allows us to locate little problems before they turn into major troubles.
