How do I stop my air conditioner from freezing up?
To sum up, here’s what you need to do to prevent the A/C from freezing:
- Have the refrigerant level checked.
- Change the filter monthly.
- Keep the supply vents open.
- Have the fan speed increased.
- Have the thermostat checked out.
- Inspect the condensate drain weekly.
- Make sure any window units you have are angled correctly.
What is wrong with my air conditioner if it keeps freezing up?
The short answer is that whenever there’s blocked airflow through any of the air conditioner’s components, a portion of the AC will freeze. There are several things that could cause blocked airflow: dirty air filters, clogged condensate line, dirty coils, refrigerant leak, a faulty fan, among others.
What do you do when your AC freezes over?
The first thing you should do once you notice your air conditioner is frozen is to turn it off and let it defrost completely. Once it has defrosted, check the airflow. Clean or replace dirty filters or remove any visible dirt or obstructions; in some cases, this could be all that is needed.
Will too much Freon cause AC to freeze up?
If there is an excess of refrigerant, it can flood the compressor and damage the mechanical components. The extra amount of refrigerant in the system may cause the evaporator doesn’t complete the gasification process and that the compressor could work with liquid.
Can your AC freeze in the summer?
Unfortunately, it’s possible 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 become frozen. If this has happened to your air conditioner, don’t panic.

- Inspect & Replace Dirty Air Filters.
How do I know if my AC is low on Freon?
Five Signs your AC is Low on Freon
- It takes much longer than it should to cool off your home.
- Your utility bills are higher than usual.
- The air coming out of your vents isn’t cold.
- Ice has started to build up on your refrigerant line.
- You hear loud or unusual noises coming from your unit.
Why does my AC freeze up when it’s hot outside?
It’s due to pressure changes in the refrigerant coil, which change the warm airflow and/or the refrigerant amount in the coil—and you get a freeze-up. The best way to avoid this problem is to routinely schedule air conditioner maintenance.
How often should you add Freon to AC?
If everything is working properly, your AC should never need refrigerant. In fact, a central air conditioner should never need refrigerant added unless there’s a refrigerant leak. We’ll explain how an AC uses refrigerant and what to do if you think your system is low on refrigerant.
Why does my air conditioning unit freeze up?
If your air conditioner is low on refrigerant, then your air conditioner can freeze up. This is due to lower pressure inside the system itself . This is because now there is less Freon in your system, but it is still being forced to expand the same amount – more expansion equals a cooler temperature.
Why do central air conditioning units freeze up?
Causes for Central Air Conditioner Freezing Up Clogged Air Filter, Coils, or Obstruction in Front of Return Grille. Low on Refrigerant. Another major cause that makes air conditioning units freeze up. Bad TXV Valve. Non Functioning Blower Motor. Low Ambient Temps. Pitted Contactor on Condensing Unit.
