What Causes an Air Conditioner to Freeze – 4 Reasons You Should Know About
- Low Level of Refrigerant: If you are wondering what causes an air conditioner to freeze up, one of the most common reasons is low refrigerant levels. Refrigerant is the cooling substance that is used to cool down the air in your air conditioner. When there is not enough of this cooling substance, the evaporator coil can get too cold and freeze up. If you notice ice formation on your AC, it may be low on refrigerant. So, be sure to get in touch with a professional HVAC technician to get it refilled and determine the source of the AC refrigerant leak.
- Dirty or Clogged Air Filters: Dirty and clogged air filters restrict the airflow, which makes the evaporator coil get too cold and freeze. To avoid this, make sure to switch out your air filters every one to three months, depending on how much you are using your AC.
- Blocked Air Ducts: Another reason that can cause your air conditioner to freeze up is blocked air ducts. If your air ducts are clogged or blocked, it can affect the cooling system in your home. This can lead to your evaporator coil freezing up. To make sure your air is flowing properly, consider calling a professional HVAC company like Galmiche & Sons and have their technicians inspect and clean your air ducts.
- Issues with the Blower Fan: A faulty blower fan can also cause your air conditioner to freeze up. If the blower fan isn’t working properly, the cool air won’t be circulating around your home as it should and the evaporator coil could freeze up. If you notice that your AC unit is freezing up, consider getting the blower fan inspected and fixed up by a professional HVAC technician.
