There are lots of reasons why your AC system freezes up.
Double-checking the air filter isn’t clogged and airflow isn’t restricted are the only things you can safely take care of without professional help. If you need to install a new the filter, you can accelerate the melting process by turning off the system 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 unit freezes a second time, contact Midland Air Service Experts to repair the issue.
Here are a couple other other reasons why your equipment may be freezing up.
Insufficient refrigerant—A frozen system can be caused by a refrigerant leak.
What causes a leak?
- Weak solder joints
- Friction from piping rubbing against other parts
- Ruptured valves
- Loose fittings
How long your unit has been working and the area of the leak play a role in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil gets dirty and causes troubles similar to a clogged filter. You’ll gradually get lower airflow until your system freezes or stops cooling. You’ll need to get in touch with Midland Air Service Experts to take care of the problem.
Malfunctioning blower motor or relay—A blower motor working at an inaccurate speed or not turning on at all can lead to freezing. It may also be sporadic, going at top speed and going slower after it gets warm. Or a relay can force it to run one time and not the following time. In either state, you will need to call Midland Air Service Experts to correct the problem.
