There are lots of reasons why your AC system freezes up in Kitchener. Nearly all of them usually call for professional AC repair.
Checking the air filter isn’t dusty and airflow isn’t restricted are the only things you can safely fix on your own. If you need to replace the filter, you can accelerate the defrosting 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 disappeared.
After the ice is gone, turn the temp back to normal. If your system freezes again, contact Hammond Plumbing & Heating to take care of the problem.
Here are a few other reasons why your system may be freezing up.
Insufficient refrigerant—Freezing can be caused by a refrigerant leak.
What causes a leak?
- Fragile solder joints
- Resistance from piping jarring against something
- Ruptured valves
- Unsecured fittings
How long your equipment has been working and the location of the leak play a part in whether you should repair or replace your AC system.
Dirty evaporator coil—As time passes, the evaporator coil attracts dirt and leads to troubles similar to a dirty filter. You’ll gradually receive lower airflow until your unit freezes or halts cooling. You’ll need to get in touch with Hammond Plumbing & Heating to repair the problem.
Malfunctioning blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can result in freezing. It may also be sporadic, going at full speed and going slower after it gets too hot. Or a relay can make it start one time and not the following time. In either case, you will need to call Hammond Plumbing & Heating to fix the trouble.
Scheduling yearly AC maintenance or heat pump maintenance might help you skip this issue. Our Experts will fully check and clean your unit, which usually allows us to locate small problems before they turn into major problems.
