Discovering ice on your air conditioner can be alarming—especially when it’s the middle of a heatwave and your home’s comfort is on the line. While it may seem counterintuitive for ice to form on equipment designed to cool, it’s actually a common sign that something’s not quite right with your system.
You might need AC repair in Centralia, WA. But you might be able to sort this out yourself! If you see frost or ice on your indoor or outdoor AC unit, don’t panic. Here’s what to do next to protect your system and your home.
Shut It Down and Let the Ice Melt
First things first: turn your air conditioner off immediately. Running an AC that’s frozen over can cause major damage to the compressor and other vital parts. After shutting it down, let the ice melt naturally. Do not try to chip away at the ice, as this can damage delicate coils and fins. Give it time to thaw completely. Depending on how much ice has built up, this might take several hours.
Monitor Drainage to Avoid Water Damage
As the ice melts, be mindful of where that water is going. Place towels or a shallow pan under any indoor unit that might leak as it thaws. Keep an eye on the condensate drain line, too. If it clogs, you could end up with water damage or mold. Once the unit is fully thawed, inspect the area to make sure all the water has drained properly.
Replace the Air Filter
A clogged or dirty air filter is one of the most common culprits for a frozen air conditioner. When airflow is restricted, the coil can get too cold and freeze over. After the system has thawed, replace the air filter with a fresh one. This simple step can do wonders for your AC’s performance and efficiency.
Gently Clean the Coils
While you’re at it, check the evaporator coil inside and the condenser coil outside. Dust and debris can block airflow and contribute to icing problems. Gently vacuum or wipe down any visible dirt. Be careful—these coils are delicate. If you’re not comfortable cleaning them yourself, it’s best to have a professional handle it.
Turn the System Back On
Once you’ve thawed the ice, cleaned the coils, and replaced the air filter, try running your AC again. If it starts cooling properly and no ice forms after a few hours, you may have caught the problem early. However, keep an eye out over the next few days.
If It Freezes Again, Call the Pros
If ice starts to build up again, there may be a deeper issue that needs professional attention. Low refrigerant levels, a malfunctioning blower fan, blocked ducts, or problems with the thermostat can all cause repeated freezing. These issues are not DIY-friendly. Handling refrigerant, for example, requires a certified technician.
