Why Does My Air Conditioner Freeze in the Summer?

June 30, 2015

Your home’s central air conditioner works hard to keep you and your family cool during the hottest times of the year in Charleston. Unfortunately, it’s fairly common for your air conditioner to become overworked, possibly restricting the airflow to your home. As toasty as it may be outside, your air conditioner can actually ice over. If this has happened to your air conditioner, don’t panic. Keep reading to find out why this happens and if you should schedule air conditioner service to take care of the problem.

If your air conditioner becomes frozen, the culprit is the evaporator coil within the condenser unit. There are two likely reasons the coil may freeze. First, the airflow through the coil is restricted. The system is trying to send more cold air through the coil than it can handle and therefore frost starts to concentrate on the outside and slow the process even more. Eventually the frozen water may cause damage to the components of your AC.

If this is not the case, a frozen AC may be due to a low level of refrigerant. Similarly, if this is the case, there simply isn’t enough “juice” to properly push the air through the coil and things start to freeze up, giving your air conditioner a layer of ice and preventing your home from receiving the cool air it needs.

If your air conditioner has stopped running properly and shows visible signs of frost or ice, don’t worry. Follow these simple steps and your home will be properly cooled again in no time.

  • Go to the thermostat and turn off your air conditioner completely.
  • Look at other areas of your AC through which air flows to make sure air is not restricted. Ensure your air filters are clean and all the registers and vents are free of debris.
