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 Niagara Falls. Unfortunately, it’s fairly common 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 freeze. If this has happened to your air conditioner, don’t panic. Keep reading to find out why an air conditioner freezes and if you should schedule air conditioner service to deal with the situation.

If your air conditioner ices over, the area to focus on 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 condenser than it can handle and therefore frost starts to build up on the outside and slow the process even more. Eventually the frozen water can cause damage to the key parts 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 adequately move the air through the coil and things start to freeze up, giving your air conditioner a layer of ice and keeping your home from receiving the cool air it needs.

If your air conditioner has stopped working properly and is covered in 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 completely.
  • View 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 open.
