Why is my AC system freezing up?

There are many reasons why your AC system freezes up in Elkhart. Nearly all of them frequently need experienced AC repair.

Double-checking the air filter is clean and airflow isn’t restricted are the only work you can safely handle without professional help. If you need to replace the filter, you can hasten the thawing process by turning off the unit and turning on the fan. If you have a heat pump, you can switch it to heat mode until the ice is gone.

After the ice disappears, switch the temperature back to normal. If your unit freezes repeatedly, contact BW/Cook Service Experts to fix the issue.

Here are a couple other other reasons why your equipment may be freezing up.

Low refrigerant—Freezing could be a result of a refrigerant leak.

What creates a leak?

  • Weak solder joints
  • Resistance from piping vibrating against other components
  • Broken valves
  • Loose fittings

How long your equipment has been running and the spot of the leak determine whether you should repair or replace your AC system.

Dusty evaporator coil—Over time, the evaporator coil attracts dirt and creates problems much like a clogged filter. You’ll gradually lose airflow until your equipment freezes or stops cooling. You’ll need to call BW/Cook Service Experts to fix the issue.

Malfunctioning blower motor or relay—A blower motor working at an inaccurate speed or not running at all can result in freezing. It can also be sporadic, going at maximum speed and going slower after it gets too hot. Or a relay can make it run one time and not the following time. In either situation, you will need to get in touch with BW/Cook Service Experts to correct the problem.

Booking regular AC maintenance or heat pump maintenance may help you bypass this malfunction. Our techs will fully check and clean your system, which frequently allows us to pinpoint little issues before they turn into huge issues.
