Finding out the reason behind the freezing up of your AC can be frustrating, but it is not an uncommon problem. How can something that works all day during summer be prone to freezing? There can be many reasons why your air conditioner may be freezing up. Many homeowners are not well equipped with the knowledge to understand all the reasons and prevent the problem independently.
How to Understand That Your AC is freezing up?
If you can’t fix the freezing problem of your AC on your own, you might need to call an HVAC expert to troubleshoot. But at first, you need to understand how it is like when your AC is freezing up.
When you are in doubt that your AC may be freezing up, check the supply register. If the supply register is warm, the evaporator coil of your AC might be frozen. You can open the panel and check for ice. Remember that if there is a lack of ice, that doesn’t necessarily mean that there is no freezing problem. However, if you see ice in the panel, it surely indicates that your AC is frozen.
Common Causes for Freezing up of AC
There are two top causes that lead to an AC freeze-up. If you are able to understand the causes, you can get in front of them and may never experience an AC freezing problem. We have also included how you can fix them on your own. Keeping your AC in its excellent health and condition will help it to run efficiently while saving you a lot on your utility bill.
1. Blocked Air Flow:
Your air conditioner needs to have a constant airflow so that the coils don’t settle with humidity and freeze. You need to be sure that the air filters of your air conditioning system are clean and are not clogged with dirt or debris. Dirty air filters interrupt the airflow, and it is best to change the air filters if they are old and more soiled. Plus, adjusting the air filters of the air conditioning system enhances its efficiency by 5% to 15%.
How to Fix It?
If you find your air filters are blocked, you may also face an airflow problem. The first thing you need to do is turn off the power supply of the air conditioner and let it defrost. Once it is thawed, turn on the fan only for the next hour. Use the time to clean the air filters with water, mild soap, and a soft-bristled brush.
2. Refrigerant Leak:
The refrigerant line of your AC may get clogged and cause leakage. If the fan of the AC stops moving, it may cause a drop in the pressure, and as a result, the refrigerant expands too much and becomes colder than expected. A low level of the refrigerant can cause a freezing up of your AC. Some of the refrigerant problems may be easier and cheaper to fix. But if any of the issues seem permanent, it is always better to invest in a new air conditioner.
How to Fix It?
If your air conditioner is freezing due to refrigerant leak, it is better to tackle the problem with the help of professional HVAC experts. Though refrigerants can be handled safely at home, it is always better to get it handled under the supervision of a professional.
