As the temperature rises outside, the last thing you want is for your air conditioning system to freeze. Not only is this problem frustrating, but it can also lead to costly repairs and expenses if left unresolved. Thankfully, with this guide, you can learn what causes an AC to freeze up so that you can promptly address the problem and avoid additional issues in the future.
Are you ready to get started? Below, let’s discuss some of the potential reasons why your air conditioner is freezing up.
One of the most common reasons an air conditioning system freezes is poor airflow. If your system cannot circulate air properly, it will cause the evaporator coils to freeze over time. This can be caused by a dirty air filter, blocked air ducts, or even a faulty blower motor. When your air filter is clogged, it restricts the amount of air that flows through your system, leading to reduced airflow and high humidity levels.
It’s plain to see how poor airflow can be what causes an AC to freeze up. If you suspect that you’re experiencing this problem, call an HVAC technician to take a closer look at your system. You can also take steps to fix your airflow. Here are some helpful tips you can use:
The refrigerant in your air conditioning unit is responsible for cooling the air that passes over the evaporator coils. If there is not enough refrigerant in your system, this could be why your air conditioner is freezing up. Low refrigerant levels are often caused by refrigerant leaks, which can happen when there is a hole in the refrigerant line or a faulty connection. Refrigerant leaks can be hard to detect on your own, and it’s important to call an experienced HVAC professional to inspect your system periodically.
Evaporator Coil Problems
The evaporator coils in your air conditioning system are responsible for cooling the air in your home. If they are dirty or damaged, they can become too cold and freeze. Dirty coils reduce airflow and can cause your system to work too hard to cool your home. Damaged coils can also cause a refrigerant leak, leading to low refrigerant levels and a frozen system. To prevent evaporator coil problems, it’s important to change your air filters regularly and schedule routine maintenance to keep your coils in good condition.
Faulty Blower Motor
As mentioned earlier, the blower motor in your air conditioning system plays a crucial role in circulating air throughout your home. If it is faulty, this can lead to poor airflow and can ultimately be why your air conditioner is freezing up. Faulty blower motors can be caused by worn-out belts, dirty bearings, or even burnt-out capacitors.
If you suspect that your blower motor is causing your system to freeze, it’s important to have an HVAC technician inspect it and perform the necessary repair or replacement. Don’t hesitate to turn to Adon for assistance; we can provide you with an air conditioning repair in Sherman, TX, or one of the surrounding communities.
Clogged Drain Line
The drain line in your air conditioning system is responsible for removing excess moisture that accumulates during the cooling process. If the line becomes clogged and cannot drain properly, the moisture can build up and freeze on the coils. Unfortunately, this can be what causes an AC to freeze up.
This particular situation can happen when dirt, debris, or algae block the line or when the line becomes kinked or bent. If you want to prevent clogged drain lines, it’s essential to have your system inspected regularly, especially before the summer months when your system is working harder to cool your home.
