There are lots of reasons why your AC system freezes up.
Checking the air filter isn’t clogged and airflow isn’t restricted are the only work you can safely handle yourself. If you need to replace the filter, you can hasten the melting process by switching off the system and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice has melted.
After the ice disappears, switch the temp back to normal. If your unit freezes a second time, get in touch with A1 Chesney Service Experts to fix the malfunction.
Here are a couple other other reasons why your equipment might be freezing up.
Low refrigerant—Freezing may be caused by a refrigerant leak.
What leads to a leak?
- Weakened solder joints
- Grating from piping vibrating against an object
- Ruptured valves
- Loose fittings
How long your equipment has been working and the spot of the leak determine whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil attracts dirt and leads to troubles similar to a dusty filter. You’ll gradually receive lower airflow until your unit freezes or stops cooling. You’ll need to call A1 Chesney Service Experts to fix 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 sporadic, going at full speed and going slower after it gets too hot. Or a relay might make it start one time and not the subsequent time. In either situation, you will need to call A1 Chesney Service Experts to repair the trouble.
Requesting yearly AC maintenance could help you avoid this issue. Our technicians will meticulously check and clean your system, which frequently allows us to find little troubles before they become large problems.
