There are a lot of reasons why your AC system freezes up.
Making sure the air filter isn’t clogged and airflow isn’t restricted are the only tasks you can safely fix on your own. If you need to install a new the filter, you can speed up the defrosting process by switching off the unit and switching on the fan. If you have a heat pump, you can turn it to heat mode until the ice has disappeared.
After the ice is gone, move the temperature back to normal. If your system freezes a second time, contact Stevenson Service Experts to take care of the malfunction.
Here are several other reasons why your equipment might be freezing up.
Insufficient refrigerant—A frozen system could be created by a refrigerant leak.
What leads to a leak?
- Fragile solder joints
- Friction from piping jarring against something
- Broken valves
- Slack fittings
How long your unit has been running and the location of the leak play a part in whether you should repair or replace your AC system.
Filthy evaporator coil—Over time, the evaporator coil attracts dirt and creates problems similar to a dusty filter. You’ll progressively lose airflow until your system freezes or quits cooling. You’ll need to get in touch with Stevenson Service Experts to repair the malfunction.
Broken blower motor or relay—A blower motor going at the wrong speed or not running at all can result in freezing. It can also be sporadic, starting at maximum speed and going slower after it heats up. Or a relay could force it to run one time and not the subsequent time. In either situation, you will need to call Stevenson Service Experts to repair the trouble.
