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 Calgary. Unfortunately, it’s fairly common for your air conditioner to become overworked, potentially restricting the airflow to your home. As hot as it may be outside, your air conditioner can actually freeze. If this has happened to your air conditioner, don’t panic. Keep reading to find out why an air conditioner freezes and if you should schedule air conditioner service to deal with the issue.

If your air conditioner becomes frozen, the area to focus on is the evaporator coil within the condenser unit. There are two typical reasons the coil could freeze. First, the airflow through the coil is restricted. The air conditioner is trying to force more cold air through the space than it can handle and therefore frost starts to accumulate on the system and slow the process even more. Eventually the frozen water can cause damage to the components of your AC.

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 adequately 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 running properly and has developed a layer 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 completely.
  • View 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.
