As the hot months of the summer approach, many of us worry about our air conditioner’s ability to keep up with the increased workload.

An air conditioner that is frequently freezing up can be a serious, stressful situation, making it a good idea to learn about some of the common causes of AC freezing.

If you’ve been wondering: Why is my central air conditioning freezing up?

Here are a few of the most common causes of this issue and how you can get help.

Restricted Air Flow

Unrestricted airflow is a key component of a properly functioning air conditioning system. When airflow is blocked, it can cause major problems with your air conditioner, including freezing your unit. The main reason for this has to do with the evaporator coil.

Your air conditioner works by passing air from your home over the evaporator coil so that heat can be removed from the air and then returned to your home. If the amount of air that passes over your evaporator coil is reduced or eliminated completely, the refrigerant in your system will lower the temperature in your unit instead of from the air, resulting in freezing.

If you find that you have a frozen AC unit, check the airflow within your system to make sure your evaporator coil is receiving air as it should.

Leaking Refrigerant

One of the primary reasons that your central air conditioning system is able to effectively cool your home is the use of a refrigerant like Freon. When the amount of Freon in your AC system drops, it reduces the efficiency of your air conditioner and increases the likelihood that you will experience freezing.

While it’s normal for air conditioners to lose a certain amount of refrigerant over time, it is also possible that your system may be experiencing a refrigerant leak, especially if your air conditioner is constantly freezing up. Examine your air conditioner for signs of leaking refrigerant, including excess moisture in and around your AC unit.

If you suspect that your refrigerant is leaking and causing your system to freeze, you need to make sure to call an HVAC professional for assistance.

Get Help from an HVAC Company

Because having an air conditioner freeze up is such a concerning situation, many homeowners try to fix the issue themselves. While this is understandable, it may result in damage to your system if you’re unfamiliar with air conditioner repair.

Instead of trying to handle the repairs yourself, you should consider calling an HVAC repair company. An experienced repair company will be well aware of the different causes of an air conditioner freezing up and will be able to quickly examine your system and identify the problem. They will also be able to schedule quick and effective repair so that your freezing problems end and your air conditioner will be ready for summer.

Finding a company that has a successful track record of servicing air conditioners in Scottsdale is the best way to keep your air conditioner from freezing up.
