The reason for your AC freezing up is probably a combination of factors, but here are some common culprits:

  • Dirty or clogged air filter: Your air filter is designed and specifically placed in your air handler to prevent the passage of pollutants and contaminants into your living space. It also keeps your AC system clean. When it becomes dirty or clogged, however, it can begin to impede the passage of cool air. This cold air can buildup on your evaporator coil and cause it to freeze.
  • Blower motor malfunction: Your blower motor is responsible for sending the recently cooled air in your air handler throughout the ductwork. It is one of the important engines of your AC. Over time, it can become clogged with dust and debris and begin to malfunction. This can dramatically reduce the flow of cool air from your air handler to your ductwork and cause the cold air to build up on your evaporator coil.
  • Low refrigerant: Your air conditioning system requires a precise amount of refrigerant to operate properly. The entire heat transfer process depends on the refrigerant; it is the blood of your cooling system. If there is not enough refrigerant in circulating through the coils, it can cause all sorts of problems to arise, including ice on the indoor coils.

We hope this gives you some sense of how your AC freezes up. It’s important to act quickly. Call Service Doctors for air conditioning repair in Gaithersburg, MD today!
