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 Nashville. 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. Read on to find out why it has happened and if you should schedule air conditioner service to address the situation.

If your air conditioner freezes up, the area to focus on is the evaporator coil within the condenser unit. There are two typical reasons the coil may freeze. First, the airflow through the coil is restricted. The system is trying to push more cold air through the coil than it can handle and therefore frost starts to concentrate on the system and slow the process even more. Eventually the frozen water can cause damage to the inner workings of the air conditioner.

If this is not the case, a frozen AC may be due to a lack of refrigerant. Similarly, if this is the case, there simply isn’t enough “juice” to completely transport the air through the coil and parts 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 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. Ensure your air filters are clean and all the registers and vents are open.
