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 San Antonio. Unfortunately, it’s more likely than you might think for your air conditioner to become overworked, and actually restrict 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 it has happened and if you should schedule air conditioner service to deal with the situation.

If your air conditioner becomes frozen, the culprit is the evaporator coil within the condenser unit. There are two likely reasons the coil might freeze. First, the airflow through the coil is restricted. The air conditioner is trying to push more cold air through the space than it can handle and therefore frost starts to build up on the system and slow the process even more. Eventually the frozen water may cause damage to the key parts 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 completely move the air through the coil and the coil and the parts around it 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 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 totally.
  • Look at 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 cleared off.
