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 Kitchener. Unfortunately, it’s fairly common for your air conditioner to become overworked, possibly restricting 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 an air conditioner freezes and if you should schedule air conditioner service to address the issue.

If your air conditioner ices over, the culprit 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. The system is trying to push more cold air through the condenser than it can handle and therefore frost starts to accumulate on the system and slow the process even more. Eventually the frozen water could cause damage to the key parts 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 properly 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 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 all the way.
  • Look at other areas of your system through which air flows to make sure air is not restricted. Ensure your air filters are clean and all the registers and vents are cleared off.
