Air Conditioning – Why Evaporator Coil Cleaning is Crucial for Your Business

Evaporator coils are key components in heating, ventilation, and air conditioning (HVAC) systems, and play an important role in heat exchange.  Keeping these coils clean is important because it helps the system work efficiently, saves energy, and reduces costs. In short, well-maintained evaporator coils are key to effective and economical air conditioning.

Coil Condition

The Impact of Coil Condition on System Performance

The condition of evaporator coils directly influences your HVAC system’s efficiency. Clean coils ensure optimal heat absorption, leading to reduced energy consumption and lower utility bills.

Benefits of Regular Coil Cleaning

  • Energy Efficiency and Cost Savings: Clean coils operate more efficiently, reducing energy costs. This is a key aspect of HVAC system maintenance.
  • Consistent Cooling Performance: For businesses where the working temperature is critical and the cool temperature is required to be consistent. Ensuring coils are cleaned regularly is essential to maintain this.
  • Prevention of Ice Formation and System Damage: Regular cleaning helps prevent issues like ice formation, which can damage the unit and may lead to costly repairs.
  • Extended HVAC System Lifespan: Consistent maintenance, including coil cleaning, prolongs the life of your HVAC system.
  • Indoor Air Quality Improvement cleaning of evaporator coils is crucial in preventing the build-up of mold, bacteria and allergens. This is especially important in humid climates where there’s a higher risk of these harmful elements growth.
  • Enhancing Airflow and Efficiency: Clean coils ensure better airflow and system efficiency, which directly impacts indoor air quality. Improved air quality is beneficial for health, particularly in reducing respiratory issues and allergies.

Neglecting Coil Maintenance:

Overlooking regular cleaning can lead to decreased efficiency, increased operating costs, and potential system breakdowns. In environments with unique climatic conditions, this neglect can be particularly detrimental.

Recommended Cleaning Frequency

  • Bi-annual Cleaning: This is commonly recommended, especially in environments with high dust or pollen levels.
  • Tailored service: The frequency may need to be increased based on the specific location and air quality required or if the cool temperature is critical to business operations.


What are the symptoms of a dirty evaporator coil?

Symptoms of a dirty evaporator coil include reduced cooling efficiency where the air conditioner may not cool effectively, increased energy bills due to the system working harder, ice build-up on the coil caused by restricted airflow, and poor indoor air quality resulting from dust and mold on the coil.

How do I know if our evaporator coil needs cleaning?

You can tell if your evaporator coil needs cleaning if there’s visible dirt or debris on the coil, unusual noises from the HVAC unit indicating airflow blockages, a decrease in the coldness of the air coming from the AC, or an unexplained increase in energy bills.

Is AC coil cleaning worth it?

Absolutely. Cleaning the coils improves the efficiency of your AC, reduces energy costs, and extends the lifespan of the unit. Cleaning your AC coil also helps maintain good indoor air quality.

How long does it take to clean evaporator coils?

The time can vary depending on the system’s condition and accessibility.

How long do AC evaporator coils last?

With proper maintenance, evaporator coils can last 10-15 years. However, this can vary based on usage, environmental conditions, and the quality of maintenance.
