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 Wheeling. 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 ice over. If this has happened to your air conditioner, don’t panic. Continue reading this post to find out why it has happened and if you should schedule air conditioner service to deal with 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 may freeze. First, the airflow through the coil is restricted. The air conditioner 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 could cause damage to the inner workings 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 completely move the air through the coil and things start to freeze up, giving your air conditioner a layer of ice and preventing 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 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.
