How to Prevent and Fix an Air Conditioner Freeze-Up

How to Prevent and Fix an Air Conditioner Freeze-Up

Do These Four Things to Fight AC Freeze, Air conditioner freeze-ups in Las Vegas are a common problem, especially on hot days. They can be caused by a number of factors, but the two most common are blocked airflow and refrigerant leaks.

To prevent an air conditioner freeze-up:
• Change your furnace filter regularly. A dirty filter can block airflow to the unit, which can cause the coils to freeze.
• Check the condensate drain line to make sure it is not clogged. A clogged drain line can cause water to back up into the unit and freeze the coils.
• Keep the area around your air conditioner unit clear of debris. Debris can block airflow to the unit and cause the coils to freeze.
• Have your air conditioner unit serviced by a professional on a regular basis. A professional can inspect the unit for any problems, including refrigerant leaks.

If your air conditioner does freeze up:

1. Turn off the thermostat.
2. Set the fan to ON. This will circulate air over the coils and help them to thaw.
3. It may take several hours for the coils to thaw completely. Once they are thawed, you can turn the thermostat back to COOL.

If you suspect that your air conditioner has a refrigerant leak, call a professional immediately. Refrigerant leaks can be dangerous and should only be repaired by a qualified technician.

Here are some additional tips to help prevent and fix an air conditioner freeze-up:

• If you have a window air conditioner, make sure it is installed at a slight angle so that water can drain out of the unit.
• If you have a central air conditioner, check the evaporator coil to make sure it is not dirty. A dirty coil can reduce airflow and cause the coil to freeze.
• If you have a central air conditioner, check the blower fan to make sure it is working properly. A weak blower fan can reduce airflow and cause the coil to freeze.
• If you have a central air conditioner, check the refrigerant level to make sure it is correct. A low refrigerant level can cause the coil to freeze.

If you follow these tips, you can help to prevent your air conditioner from freezing up and keep your home cool and comfortable all summer long.
