There are a lot of reasons why your AC system freezes up.
Double-checking the air filter isn’t dirty and airflow isn’t decreased are the only tasks you can safely take care of on your own. If you need to install a new the filter, you can hasten the defrosting process by disabling the equipment and using the fan. If you have a heat pump, you can move it to heat mode until the ice has melted.
After the ice melts, switch the temperature back to normal. If your equipment freezes a second time, contact A-PLUS Service Experts to fix the malfunction.
Here are a couple other other reasons why your equipment may be freezing up.
Low refrigerant—A frozen system can be caused by a refrigerant leak.
What leads to a leak?
- Fragile solder joints
- Resistance from piping rubbing against an object
- Cracked valves
- Slack fittings
How long your system has been installed and the area of the leak play a role in whether you should repair or replace your AC system.
Dusty evaporator coil—As time passes, the evaporator coil becomes dirty and causes troubles much like a dusty filter. You’ll slowly lose airflow until your unit freezes or halts cooling. You’ll need to contact A-PLUS Service Experts to fix the malfunction.
Broken blower motor or relay—A blower motor working at an inaccurate speed or not turning on at all can lead to freezing. It can also be sporadic, running at maximum speed and slowing down after it gets warm. Or a relay could make it start one time and not the subsequent time. In either state, you will need to contact A-PLUS Service Experts to correct the issue.
Scheduling yearly AC maintenance can help you bypass this malfunction. Our Experts will meticulously examine and clean your unit, which typically allows us to locate small issues before they become huge problems.
