Air conditioners usually freeze when refrigerant levels are low, when airflow circulation is restricted, or when the system is not draining properly. Other situations that can cause air conditioners to freeze include problems with the thermostat, running the air conditioner during cold weather, or an improper fit on a window unit. Keeping your heating and air conditioner healthy is the most important way of keeping an air conditioner from freezing in Jacksonville. Here are a few tips on how to keep your air conditioner from freezing.

1. Check the refrigerant level. Low refrigerant levels are the most common cause of air conditioners freezing. A heating and air specialist can tell you if the refrigerant is leaking in your air conditioner.

2. Change the filter. Air conditioner filters need to be changed regularly, especially when the system if being used daily. If the filter is not changed regularly, the air cannot circulate properly and the coil will freeze. Changing the filter is one of the simplest things you can do to keep your air conditioner from freezing.

3. Opening most of the vents and increasing fan speed. Closing too many vents prevents air flow, which causes the evaporator coil to freeze. Similarly, a fan speed set too low will not circulate the air properly through the system. If the freezing is not caused by a refrigerant leak, it is most likely due to an air flow problem. A heating and air specialist in Jacksonville can help you diagnose the freezing problem and help you establish the right settings to prevent the system from freezing again in the future.

4. Check the drain pipe. If the drain pipe is blocked, the moisture that continues to accumulate will freeze. If you do not know how to check the drain pipe, a simple maintenance call is all you need to get the air conditioner fixed.
