It’s summertime, and the warm weather has finally arrived here in Mukwonago. So why is there ice on your air conditioning (AC) system?

Why Is There Ice On My AC System?

Simply put, an icy air conditioner means a problem has occurred during the system’s cycle. The evaporator coils could have gotten too cold and caused any nearby moisture in the air to freeze over them. This may cause your compressor to overheat or even freeze up too.

Maybe it’s just your compressor that has frozen, which could be a result of anything from a dirty air filter to too little or too much refrigerant.

Some other reasons you may have a frozen compressor and/or evaporator coils include an issue with the blower motor or expansion valve, turning your AC system on when it’s too cold outside, and restriction in the coil.

No matter the cause of your frosty AC system, our Midwest Heating & Cooling professionals are here to get your system working properly again.

Is My Air Conditioner Frozen?

If any part of your air conditioning equipment appears icy, your system is likely freezing up. Sometimes, however, the signs aren’t as obvious.

You may notice your AC isn’t distributing cool air, or you may hear an unusual sound, almost as if your system is hissing. Ice could be inside your system.

If you suspect your air conditioning unit has frozen, or if there are any signs of a problem with it, you should reach out to our Midwest Heating & Cooling professionals.

It is always best to address issues before they have the chance to progress. You don’t want to let the problem lead to an expensive repair.

How to Unfreeze Your AC

There are steps you can take to prevent further damage to your air conditioning equipment, such as:

  1. Turn off your air conditioning system: If you believe your air conditioner has frozen, you need to turn off your system—even if it is extremely hot outside. Allowing a frozen air conditioning system to continue running can cause parts to break and may even cause overheating and lead to a complete breakdown.

    Turn off your AC to spare yourself the trouble of greater damage and keep money in your pocket by avoiding a costlier repair or replacement.
  1. Turn the fan on your thermostat to On: This forces warm air to blow over frozen components and will help your air conditioner defrost. Turning the fan On allows for a continuous airflow to help thaw the frozen areas.
  2. Change your air filter: Be sure to replace or clean your AC filter. A clogged air filter can restrict airflow and easily cause your system to freeze—and could be the source of the problem. Be sure to replace or clean your filter every 30 to 90 days. Changing your filter can do more than promote the ideal operation of your air conditioning equipment—it can also help you cut down on energy consumption and expenses. According to the Department of Energy (DOE), you can reduce your air conditioning system’s energy use by up to 15 percent when you replace a dirty or clogged filter.
