There are a lot of reasons why your AC system freezes up.
Checking the air filter isn’t clogged and airflow isn’t restricted are the only things you can safely take care of yourself. If you need to put in a new the filter, you can hasten the defrosting process by switching off the equipment and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice has melted.
After the ice is gone, move settings back to normal. If your unit freezes a second time, call Stallion Heating Plumbing Air Conditioning to fix the malfunction.
Here are a couple other other reasons why your system might be freezing up.
Low refrigerant—A frozen system could be a result of a refrigerant leak.
What creates a leak?
- Weakened solder joints
- Friction from piping jarring against other parts
- Cracked 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.
Dusty evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and causes troubles much like a clogged filter. You’ll gradually lose airflow until your equipment freezes or quits cooling. You’ll need to get in touch with Stallion Heating Plumbing Air Conditioning to repair the problem.
Malfunctioning blower motor or relay—A blower motor going at an inaccurate speed or not working at all can cause freezing. It can also be sporadic, starting at top speed and decelerating after it gets too hot. Or a relay can make it start one time and not the following time. In either state, you will need to call Stallion Heating Plumbing Air Conditioning to fix the trouble.
