Freezing is caused by the refrigerant reaching too low of a temperature and typically there are two common problems. Everyone jumps for check the Freon charge but half the time the flow of air across the coil has been reduced so that it is not taking full advantage of the coil cooling capacity and that can also cause freezing. Check your filter and duct work for blockages or anything that could cause low air flow including something as simple as a common return register which is blocked by a piece of furniture or something else as that is part of the same air flow system. Hope that helps.

What causes an ac unit to freeze up?

The cause of you AC freezing up is not enough air flow over the coils. Iam not sure if you are tlaking about a window air conditioning unit or an outdoor unit. If it is a window unit your filter is plugged or there is something blocking the intake, this could be inside or outside. If it is an outdoor unit then your compressor fan may not be working, the unit may be sized too large or once again your filter needs changing or something is blocking the intake.

What's wrong with your AC if the tubes are freezing and the air is not as cold?

It is freezing up. We find this problem occurs particularly when it cools off somewhat outside. Turn your a/c temperature up, and your fan speed to high. This helps to keep it from freezing. More than likely you are low on refrigerant. Have you had the pressures checked. Also check you filter and ensure it is not dirty.


Central air freezing up?

Why should I choose AC winter storage?

Protection from the elements: During the winter months, your air conditioning unit is exposed to harsh weather conditions such as snow, ice, and freezing temperatures. Storing your AC unit in a designated winter storage space helps protect it from these elements, reducing the risk of damage and extending its lifespan. Prevents debris buildup: When your AC unit is left outdoors during winter, it can accumulate debris like leaves, twigs, and dirt. This buildup can obstruct the airflow, affecting the efficiency and performance of your unit. Storing it in a secure location keeps it clean and minimizes the potential for blockages. Avoids potential damage: Extreme cold temperatures can cause freezing and expansion of moisture within the air conditioning system, leading to cracks, leaks, or other damage. Storing your AC unit indoors or in a climate-controlled environment prevents exposure to freezing temperatures, reducing the risk of such issues. Saves space: If you have limited outdoor space, storing your AC unit elsewhere during the winter can free up valuable space in your yard or patio. This allows you to utilize the area for other purposes or simply keep it clutter-free. Easy reinstallation: Storing your AC unit in a designated winter storage space ensures that it remains in good condition and is readily available for reinstallation when the warmer months arrive. This can save you time and effort compared to having to clean and repair a unit that has been exposed to the winter elements.
