There are many reasons why your AC system freezes up.
Making sure the air filter isn’t dirty and airflow isn’t lowered are the only things you can safely take care of alone. If you need to install a new the filter, you can hasten the melting process by disabling 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, move the temp back to normal. If your equipment freezes a second time, contact Climate Control Service Experts to fix the issue.
Here are a couple other other reasons why your equipment might be freezing up.
Low refrigerant—Freezing up could be created by a refrigerant leak.
What creates a leak?
- Weakened solder joints
- Grating from piping vibrating against other parts
- Ruptured valves
- Loose fittings
How long your unit has been working and the spot 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 attracts dirt and creates issues much like a dirty filter. You’ll progressively lose airflow until your equipment freezes or halts cooling. You’ll need to call Climate Control Service Experts to repair the issue.
Malfunctioning blower motor or relay—A blower motor going at an incorrect speed or not running at all can create freezing. It may also be intermittent, running at maximum speed and going slower after it gets too hot. Or a relay can force it to run one time and not the following time. In either situation, you will need to call Climate Control Service Experts to repair the issue.
Booking annual AC maintenance might help you avoid this malfunction. Our pros will comprehensively examine and clean your equipment, which often allows us to catch little troubles before they become major troubles.
