There are many reasons why your AC system freezes up.
Making sure the air filter isn’t clogged and airflow isn’t decreased are the only tasks you can safely fix on your own. If you need to replace the filter, you can speed up the melting process by switching off the system and turning on the fan. If you have a heat pump, you can move it to heat mode until the ice has disappeared.
After the ice is gone, turn the temperature back to normal. If your system freezes again, contact Roland J. Down Service Experts to repair the problem.
Here are a couple other other reasons why your unit might be freezing up.
Low refrigerant—A frozen system may be a result of a refrigerant leak.
What causes a leak?
- Weak solder joints
- Friction from piping vibrating against an object
- Ruptured valves
- Unsecured fittings
How long your system has been working and the spot of the leak play a part in whether you should repair or replace your AC system.
Dirty evaporator coil—Throughout the seasons, the evaporator coil gets dirty and creates problems much like a clogged filter. You’ll progressively lose airflow until your system freezes or stops cooling. You’ll need to call Roland J. Down Service Experts to fix the problem.
Defective blower motor or relay—A blower motor working at the wrong speed or not turning on at all can lead to freezing. It might also be intermittent, running at top speed and decelerating after it heats up. Or a relay might make it run one time and not the following time. In either state, you will need to contact Roland J. Down Service Experts to correct the trouble.
