There are many reasons why your AC system freezes up in Belleville. Almost all of them typically require skilled AC repair.
Double-checking the air filter isn’t dusty and airflow isn’t lowered are the only work you can safely take care of yourself. If you need to replace the filter, you can hasten the thawing process by switching off the unit and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice is gone.
After the ice is gone, move the temp back to normal. If your unit freezes repeatedly, call D & K Heating Service Experts to repair the issue.
Here are several other reasons why your unit might be freezing up.
Insufficient refrigerant—Freezing can be caused by a refrigerant leak.
What leads to a leak?
- Weak solder joints
- Grating from piping rubbing against other components
- Broken valves
- Loose fittings
How long your system has been working and the spot of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—As time passes, the evaporator coil attracts dirt and leads to issues resembling a dirty filter. You’ll gradually receive lower airflow until your unit freezes or halts cooling. You’ll need to call D & K Heating Service Experts to repair the malfunction.
Malfunctioning blower motor or relay—A blower motor going at an inaccurate speed or not running at all can lead to freezing. It may also be intermittent, going at full speed and slowing down after it heats up. Or a relay can force it to work one time and not the next. In either case, you will need to call D & K Heating Service Experts to repair the issue.
Booking annual AC maintenance or heat pump maintenance can help you avoid this issue. Our techs will fully inspect and clean your system, which frequently allows us to discover small problems before they become major problems.
