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 hot summer months in Hillsborough. Unfortunately, it’s possible for your air conditioner to become overworked, possibly 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 this happens and if you should schedule air conditioner service to address the issue.

If your air conditioner ices over, the problem is the evaporator coil within the condenser unit. There are two typical reasons the coil might freeze. First, the airflow through the coil is restricted. Your AC is trying to push more cold air through the condenser than it can handle and therefore frost starts to accumulate on the outside and slow the process even more. Eventually the frozen water may cause damage to the key parts 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 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 working properly and is covered in 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 completely.
  • Look at other areas of your air conditioner through which air flows to make sure air is not restricted. Make sure your air filters are clean and all the registers and vents are free of debris.
