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 sweltering summers in North America. Unfortunately, it’s possible for your air conditioner to become overworked, and actually restrict the airflow to your home. As toasty as it may be outside, your air conditioner can actually become frozen. If this has happened to your air conditioner, don’t panic. Keep reading to find out why it has happened and if you should schedule air conditioner service to deal with the situation.

If your air conditioner ices over, the culprit is the evaporator coil within the condenser unit. There are two possible reasons the coil might freeze. First, the airflow through the coil is restricted. The system is trying to send more cold air through the condenser than it can handle and therefore frost starts to build up on the system and slow the process even more. Eventually the frozen water can 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 completely transport the air through the coil and the coil and the parts around it start to freeze up, giving your air conditioner a layer of ice and stopping your home from receiving the cool air it needs.

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

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