HeatingThe Importance of Cleaning the Heating Coil

The evaporator coil is an important component in your heating system, as it helps provide the warm air that blows into your home. Even though it is a large component, it has delicate, intricate parts that can be adversely affected when coated with dust and dirt. As such, it’s important to keep the coil clean to ensure comfortable, consistent heating. The trained professionals at G&S Heating, Cooling & Electrical, Inc., are heating experts, and can help with any heating repair issues you may have.

Why Dirty Coils Are a Problem

Coils become dirty during regular use. Dirt and dust settle in many places in your system, and they can collect on the coils because of condensation. When your coils aren’t cleaned bi-annually, the dirt and dust can become a thick layer. Several problems can develop from this, including:

  • Mold and mildew development – mold and mildew thrive in moist, dark places, and a dirty coil makes a great home. Having these contaminants on the coils can decrease your Indoor Air Quality as the spores are blown into your home; these contaminants also produce unpleasant odors.
  • Problems with refrigerant cycle – during the summer, the evaporation coil helps cool the refrigerant, and during winter, it does the opposite. Excess dirt and dust accumulation can act as an insulating layer on the coil, preventing the refrigerant from releasing heat as needed. This can disrupt the heat transfer process and reduce the temperature of the air blown into your home.
  • Icing – if the refrigerant cycle is disrupted enough, ice can build up on the coils. Icing occurs when the warm parts of the system stay too warm and the cool parts stay too cold. The disparity in the temperatures creates condensation, which quickly freezes on the cold parts, creating ice.

The Best Prevention: Maintenance

During a bi-annual maintenance appointment, the components in your system are cleaned, including the coils. Bi-annual cleaning helps ensure that dust and dirt don’t build on the coils, greatly reducing the possibility of the problems listed above.
