Wellington, FL Air Conditioning Repair: Why is My AC Freezing Up?

A frozen evaporator coil in your AC is a warning sign that something is wrong with your cooling system. This can happen frequently during periods of high humidity, when the natural dehumidification process is overwhelmed by the amount of water vapor in the air. It’s important to seek professional assistance as soon as you notice the freezing. In this post, we’d like to address this concern by explaining some possible causes. For more information, or to schedule Wellington, FL air conditioning repair, call Envirotech Air Quality Services today!

  • Clogged air filter: The air filter on your AC unit is designed not simply to prevent dust and debris from entering your home, but to protect the sound operation of your equipment, which will not work properly if covered in dust. Air filters should be checked at least once per month during the cooling season so that they can be cleaned or replaced when dirty or clogged. If your filter is clogged, it not only affects the cleanliness of your equipment, but it also reduces airflow. This is a common cause of frozen coils.
  • Low refrigerant: You may have come across the word “charge” when your AC was installed. The level of refrigerant running through the cooling cycle is known as its “charge,” and when this becomes low or insufficient, your coils may ice over quickly. Your system needs the correct amount of refrigerant for the heat absorption and dissipation processes to work.
  • Fan motor malfunction: Your air handler has a fan inside that extracts air from your home and sends cooled air throughout the ductwork. If there is a malfunctioning motor or faulty fan motor relay, then this air handler fan will not operate appropriately. The air in your home is an important part of the cooling process—it works with levels of refrigerant to produce the cooling effect. If this part of the process is disrupted, then it can lead to evaporator coil freeze-ups.

We hope this brief explanation gives you some idea of the complexity of your AC system, which relies on the cooperation of its parts. When you need Wellington, FL air conditioning repair, don’t wait; call the experts at Envirotech Air Quality Services to ensure that your system is ready to work all summer long.
