Air Conditioning Repair FAQ: Why is My System Icing Up?

Monday, May 13th, 2013

We need our AC systems for a lot of the year in Savannah, GA, so it’s important to take note of any problems, and to call for repair as soon as possible. One of the most common air conditioning problems  we see  occurs when your evaporator coil ices up. There are various reasons for frost in the system, and we’d like to review some of them in this post. Remember, there’s no substitute for professional service, so when you need Savannah, GA air conditioning repair services, make sure you call a certified technician at  AAction Air.

Here are a few possible reasons for your system icing up:

  • Clogged air filter: Your air filter is designed to prevent the accumulation of dust and debris on AC system components. Such materials can negatively affect the effectiveness and efficiency of your cooling system. The air filter is therefore a vital preventive measure. But when it becomes clogged, it becomes an obstruction. By blocking the cool air that the air handler emits, the cool air becomes trapped within the evaporator and this can quickly cause the coils to freeze over. Remember to check your air filter about once a month during peak cooling times to ensure that it’s not causing any airflow problems.
  • Duct leak: Your cooling system relies on the integrity of sealed ductwork to distribute the conditioned air throughout your home. But when there’s a duct leak, it can cause a system imbalance. Depending on where the duct leak is, it may lead to ice building up on your coils as a result of high humidity.
  • Low refrigerant: Your AC relies on the efficiency of the refrigerant cycle. Your outdoor compressor pressurizes the refrigerant and sends it through the coils. This process relies on a specific amount of refrigerant to function properly. When your refrigerant is low, typically caused by a leak, it can cause your system to work harder and this system imbalance may cause your coils to ice up.

There are still other reasons for your system icing up, including high humidity levels that can overwhelm your air conditioner. For exceptional Savannah, GA air conditioning services, call the experts at AAction Air Conditioning & Heating today!
