Noticing ice buildup on your air conditioner is more than just a curiosity—it’s a sign that your system is struggling. An icy AC can mean trouble for both performance and energy efficiency, and if left unchecked, it can cause lasting damage. Here’s what to do if you see ice on your system, and how to know when it’s time to call in our team for expert AC repair in Edina, MN.
Step 1: Turn Off the AC Immediately
First things first—shut the system down. Continuing to run your AC while it’s frozen can strain the compressor and lead to major system damage. Set the thermostat to “off” or turn the system off at the breaker, then switch the fan setting to “on” to help the indoor unit circulate warm air and speed up the melting process.
Step 2: Let the Ice Melt Naturally
Patience is key here. Do not try to chip away the ice manually, as this could damage delicate components like the refrigerant coils or fins. Let the ice thaw on its own. Depending on the extent of the buildup, this process could take a few hours or longer.
Step 3: Check for Proper Drainage
As the ice melts, make sure water is draining properly. A clogged or damaged condensate drain line or an overflowing drain pan could lead to water damage around your system. Keep an eye out for puddles or leaks, and ensure your condensate pan is catching and draining the meltwater correctly.
Step 4: Clean Both Indoor and Outdoor Units
Once the system is thawed, give both the indoor evaporator coil and the outdoor condenser unit a good visual check. Clear away dust, dirt, and debris that may be blocking airflow. This is a good opportunity to remove anything that could be restricting the system’s ability to operate efficiently.
Step 5: Change the Air Filter
A dirty or clogged air filter is one of the most common causes of AC freezing. It restricts airflow, which can cause the evaporator coil to get too cold and begin to freeze. Replace the filter with a clean one before restarting your system to ensure proper airflow.
Step 6: Restart and Monitor
After completing the steps above, try turning your AC back on. Monitor its operation closely over the next few hours. If the system cools as expected and no ice forms, you may have caught the issue early enough to resolve it with these maintenance steps.
When to Call in the Pros
If the ice returns after restarting the system, it’s time to bring in the experts. Persistent freezing may indicate more serious issues such as low refrigerant levels due to a leak, a failing blower motor, or problems with the thermostat or control board. These are not DIY repairs—they require the skill and tools of a licensed HVAC technician.
