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 Knoxville. Unfortunately, it’s fairly common for your air conditioner to become overworked, possibly restricting the airflow to your home. As hot as it may be outside, your air conditioner can actually ice over. If this has happened to your air conditioner, don’t panic. Continue reading this post to find out why this happens and if you should schedule air conditioner service to address the situation.

If your air conditioner freezes up, the culprit is the evaporator coil within the condenser unit. There are two likely reasons the coil might freeze. First, the airflow through the coil is restricted. The air conditioner is trying to push 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 may cause damage to the inner workings of the air conditioner.

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 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 keeping your home from receiving the cool air it needs.

If your air conditioner has stopped cooling 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 all the way.
  • View 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 cleared off.
