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 Denver. Unfortunately, it’s possible for your air conditioner to become overworked, and actually restrict the airflow to your home. As warm 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 this happens and if you should schedule air conditioner service to address the problem.

If your air conditioner freezes up, the area to focus on 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 force 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 components of the system.

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 cooling properly and shows visible signs of frost or ice, don’t worry. Follow these simple steps and your home will be properly cooled again in no time.

  • Go to the thermostat and turn off your air conditioner totally.
  • Check other areas of your AC 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 free of debris.
