Why Is My Air Conditioner Freezing Up?

There is perhaps no problem more disconcerting than an air conditioner that’s showing ice on the coils. Most homeowners know at this point that our air conditioner does not cool your home by using ice, so this is very clearly a problem. The problem is that homeowners don’t know enough about the intricacies of these systems to tell what exactly is happening.

We’re going to talk in detail about what is happening when you notice ice on your air conditioner. We’ll mention what not to do and tell you that this absolutely requires the help of a trained professional. Give us a call!

How Does Ice Form on My AC?

This is probably the burning question that’s causing you the most distress. What did you do wrong? What happened to your perfectly functioning air conditioner? Don’t worry, we’ll get into it.

Air conditioners cycle refrigerant that constantly drops and raises in temperature. Once the heat is removed from your air, it needs to be blown into your home through your air ducts. If this process is inhibited in any way, the air in your air conditioner’s coils can begin to drop to the point of freezing. And, since those coils are responsible for dehumidifying you air as well, the moisture around them will begin to freeze. This is how ice forms on your air conditioner.

However, you’re not just here to know how it happens. You’re here to understand why ice forms inside your system. So, let’s keep going!

Why Is This Happening?

There are multiple different ways that ice can form on the coils of your air conditioner. Let’s take a look at each one in detail.

  • Clogged air filter. Your AC requires steady airflow to release the cooled air. When the system starts suffocating due to a clogged air filter, the temperature will drop too low and the system will begin freezing. Make sure you change your air filter every 1-3 months to avoid this problem entirely!
  • Insufficient refrigerant charge. When your system starts leaking refrigerant, it starts performing much less efficiently. This could cause wild temperature fluctuations inside your air conditioner to the point of causing ice to form. Make sure you have a technician check the refrigerant charge every time they visit.
  • Poor ductwork. Remember how we talked about airflow? If you’ve got any problems in your air ducts, it’s going to inhibit the flow of air from your system to your home. This could cause the interior of your system to start freezing up. Make sure your air ducts provide an easy and clear route to the various parts of your home.
