What Is A Frozen AC?

August 24, 2023 | Blog

Air conditioners keep your home nice and cool, but did you know they can get too cold and freeze up? Everyone loves a frozen treat in the summer, but having a frozen air conditioner is not a treat. At Air Tech of Katy, we’re here to help keep your system running as it should!

During sweltering summers, not having a functional AC can make you frustrated and uncomfortable. Here, we discuss why your AC may freeze and why our team should be your preferred Katy AC repair technicians.

What Is A Frozen AC?

When you think of an air conditioner, you may believe that cold air is brought in from outside. That’s not true, instead, these systems remove the heat from inside and transfer it outside. Thanks to the connection between the compressor, condenser and refrigerant, they work together to keep you cool.

However, if your air conditioner freezes up during a hot day when you need it most, that’s not a normal sign. There are several reasons why your unit may have frozen up:

  • Restricted airflow: The flow may be cut off due to reasons such as dirty air filters or blocked vents.
  • Refrigerant leaks: Your refrigerant line may become damaged and leak, changing your HVAC system’s pressure. This can lead to ice formation on your evaporator coils.
  • Frozen evaporator coil: When the coil gets dirty, it freezes up quicker. This is not easy for the average homeowner to work with — it’s best to contact one of our HVAC technicians to give it a look!

Simply put, if there isn’t enough warm air for the AC to circulate and transfer the heat, the unit will freeze up and you may feel hot air going inside your home instead of cool air. 

Thaw Your Air Conditioner 

If you notice that your air conditioner has frozen, here are a few simple tips for you to combat this issue.

If you notice ice or condensation, turn off your AC for a little while. When you turn it off, keep the fan on — with the fan still on, it will blow warm air over the frozen coils, helping it defrost. However, if it ices over again, this may signal a bigger issue such as a malfunctioning AC compressor.

When maintaining your unit, check the filter. If the AC filter is dirty, this may be the culprit for it freezing over. Remember to change your air filter quarterly — at least every three months. A clean filter can help your system run efficiently and maintain good indoor air quality in your home.

If the issue is something different, like low refrigerant levels or a bad evaporator coil, the best step is to call a professional on our team to perform an inspection or tune-up.
