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 Roanoke. Unfortunately, it’s fairly common for your air conditioner to become overworked, potentially restricting 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. Continue reading this post 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 becomes frozen, the culprit is the evaporator coil within the condenser unit. There are two possible reasons the coil could 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 build up on the air conditioner and slow the process even more. Eventually the frozen water can cause damage to the components of the system.

If this is not the case, a frozen AC may be due to a shortage of refrigerant. Similarly, if this is the case, there simply isn’t enough “juice” to completely move 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 keeping your home from receiving the cool air it needs.

If your air conditioner has stopped working properly and has developed a layer of frost or ice, don’t worry. Follow these simple steps and your home will be feeling good again in no time.

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