There are lots of reasons why your AC system freezes up in Hillsborough. Almost all of them typically require pro AC repair.
Making sure the air filter isn’t dusty and airflow isn’t decreased are the only things you can safely fix without professional help. If you need to install a new the filter, you can accelerate the defrosting process by switching off the system and using 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, turn the temperature back to normal. If your unit freezes again, get in touch with Fras-Air/General Service Experts to repair the malfunction.
Here are a couple other other reasons why your unit may be freezing up.
Insufficient refrigerant—Freezing up could be created by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Grating from piping rubbing against something
- Ruptured valves
- Slack 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.
Filthy evaporator coil—Throughout the seasons, the evaporator coil attracts dirt and leads to problems resembling a dusty filter. You’ll slowly receive lower airflow until your equipment freezes or quits cooling. You’ll need to contact Fras-Air/General Service Experts to repair the problem.
Defective blower motor or relay—A blower motor going at an incorrect speed or not turning on at all can lead to freezing. It could also be intermittent, going at top speed and going slower after it gets warm. Or a relay may cause it to run one time and not the next. In either case, you will need to get in touch with Fras-Air/General Service Experts to repair the trouble.
Booking yearly AC maintenance or heat pump maintenance may help you skip this problem. Our technicians will comprehensively examine and clean your equipment, which usually allows us to discover small issues before they cause large problems.
