Why Evaporator Coil Cleaning Is Important

Boss and employees meet in NY office and enjoy clean air

Many critical components must work together to make a commercial air conditioner operate correctly, and one of the most essential is the evaporator coil. This part is located near the air handler inside the building; it’s a copper or aluminum coil containing refrigerant.

When the air handler blows warm indoor air over the evaporator coil, the refrigerant inside absorbs the heat, leaving cool air to circulate back into the building. Moisture in the air also condenses on the coil, which drips into a condensate pan and drains away. Since moist air feels warmer than dry air, this dehumidification is another way air conditioning makes indoor air more comfortable.

The Importance of Evaporator Coil Cleaning

  • Better efficiency: A clean coil absorbs more heat, allowing the building to cool down faster. This increases the efficiency of your commercial air conditioner, lowering your cooling bills in the process.
  • Improved indoor comfort: When your building cools off quickly, the inside stays more comfortable, no matter how hot it gets outside.
  • Extended equipment life span: An air conditioner that performs efficiently experiences less wear and tear. This means that cleaning the coil regularly can prolong the service life of your system.
  • No frozen coil: When a dirty coil can’t absorb enough heat, the refrigerant inside may freeze, causing ice to form. This shuts down the system and results in water damage as the ice melts. You can avoid this costly inconvenience by keeping the coil clean.
  • Better indoor air quality: Consider that if mold grows on the evaporator coil, indoor air blowing over it will pick up and transport spores into the building. A clean coil helps to prevent this.

How to Keep the Evaporator Coil Clean

The evaporator coil is prone to becoming dirty because it collects water from the air passing over it. The resulting moisture attracts all kinds of debris, making evaporator coil cleaning an important part of your commercial HVAC maintenance plan. Here’s how to keep the coil clean:

  • Replace the filter: Warm air from inside the building may carry dust, dirt, hair, fibers, and microorganisms. That’s why the first line of defense is a clean air filter. During the height of the cooling season, check the filter monthly and replace it when it starts to appear clogged.
  • Install a UV germicidal system: Specific wavelengths of ultraviolet light are known to deactivate microorganisms such as mold, bacteria, and viruses. Installing a UV germicidal light aimed at the evaporator coil can prevent anything organic from growing there. Hire a commercial HVAC contractor to install one for you.
  • Leave the cleaning to a professional: Evaporator coil fins are extremely delicate and prone to damage. Using the incorrect cleaning products or handling the fins with too much force could cause them to bend. This may decrease the performance of your cooling system and result in costly repairs. Lack of experience could even increase the risk of electric shock. To protect your investment and ensure your safety, leave commercial AC coil cleaning to a licensed technician.
  • Schedule annual commercial AC maintenance: A professional cooling equipment tune-up includes a coil inspection and deep cleaning. We recommend scheduling this service once or twice a year, including once in the spring to set up your air conditioner for an energy-efficient summer.
