There are a lot of reasons why your AC system freezes up in Houston. Almost all of them frequently need professional AC repair.
Making sure the air filter isn’t dirty and airflow isn’t lowered are the only work you can safely handle yourself. If you need to put in a new the filter, you can speed up the melting process by disabling the system and switching on the fan. If you have a heat pump, you can switch it to heat mode until the ice has melted.
After the ice melts, move the temperature back to normal. If your unit freezes again, contact Church Services to correct the malfunction.
Here are several other reasons why your system might be freezing up.
Low refrigerant—A frozen system may be caused by a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Resistance from piping rubbing against something
- Broken valves
- Loose fittings
How long your unit 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—Over time, the evaporator coil attracts dirt and leads to issues similar to a dirty filter. You’ll progressively get lower airflow until your equipment freezes or quits cooling. You’ll need to contact Church Services to take care of the problem.
Defective blower motor or relay—A blower motor going at the wrong speed or not running at all can lead to freezing. It may also be irregular, running at full speed and decelerating after it gets too hot. Or a relay could cause it to run one time and not the following time. In either case, you will need to call Church Services to repair the problem.
