Why Is My AC Freezing Up? Causes, Fixes & When To Call a Pro


Air Conditioning

While it might sound surprising, an air conditioner can actually freeze up under certain circumstances. Cold, rainy weather, poor airflow, or refrigerant issues can cause your system’s outdoor unit to freeze, making it unable to function properly. If left frozen for too long, it can lead to serious damage and expensive repairs.

In this post, we’ll cover the common causes of a frozen AC unit, how to fix it, and when to call a professional to get your air conditioner running smoothly again.

Causes of a Frozen AC Unit

If your air conditioner is freezing up, several issues could be to blame. Here’s a closer look at the most common causes:

  • Clogged air filters: Airflow needs to be clear throughout the AC system to prevent freezing, and clogged air filters will stop that quickly.
  • Low refrigerant levels: Improper refrigerant levels can stop the AC from running correctly and cause issues for your system.
  • Dirty evaporator and condenser coils: Debris and dust can build up on the coils and lead to bad airflow.
  • Damaged air ducts: When air can’t flow properly through the air ducts, the system can freeze up and experience other issues.

These are just a few issues that could lead to your air conditioner having frozen parts. It’s best to call a professional to safely repair the damaged parts and ensure that your AC system can run properly and efficiently once again.

What To Do if Your AC Freezes Up?

If you notice your air conditioner freezing up, act quickly to avoid long-term damage. Here’s what you can try:

  • Replacing your air filters
  • Running your AC for short periods
  • Cleaning your outdoor unit with water
  • Cleaning away debris from around your outdoor unit

If these techniques don’t fix anything with your air conditioner, it’s time to call an expert. Professional HVAC technicians can get to the bottom of the problem fast and perform the proper repairs to your system. Working with an expert, you can rest easy knowing that your air conditioner will work properly again.

Why You Should Act Quickly

A frozen AC unit isn’t just an inconvenience — it can cause long-term damage to key components like the compressor and coils. If left unchecked, you may face higher energy bills, poor cooling performance, or even a full AC system replacement.
