There are lots of reasons why your AC system freezes up in Houston. Almost all of them typically need professional AC repair.
Making sure the air filter isn’t dirty and airflow isn’t decreased are the only things you can safely handle yourself. If you need to put in a new the filter, you can speed up the melting process by switching off 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, turn the temperature back to normal. If your unit freezes again, contact Church Services to correct the issue.
Here are several other reasons why your system might be freezing up.
Low refrigerant—Freezing up could 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 equipment has been installed and the spot of the leak play a part 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 slowly get lower airflow until your unit freezes or halts 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 cause freezing. It may also be irregular, going at full speed and decelerating after it gets warm. Or a relay could cause it to run one time and not the next. In either case, you will need to get in touch with Church Services to repair the problem.
