As your residential and commercial customers are preparing to turn on their air conditioners for the season, it is important to remind them of the role coil cleaning plays in air conditioner maintenance. While condenser and evaporator coils have different functions within the a/c unit, keeping them clean offers the same benefits.

Benefits of Coil Cleaning for A/C Unit Maintenance
It is recommended that a comprehensive coil cleaning service be performed at least once per year in order to achieve the following benefits:

• Energy Savings – When the coils within an a/c unit are coated with dirt and grime, their energy efficiency drops dramatically. This means the unit has to work harder to run, resulting in higher electric bills among your customers. With coil cleaning alone, your customer can experience a 16% efficiency gain.

• System Performance – The condenser and evaporator coils are key components of an a/c unit, so it stands to reason that if they are dirty, the performance will be impacted. Even the most expensive, top-of-the-line equipment simply can’t function optimally with dirty coils. In fact, dirty coils can cut a unit’s cooling capacity by 7%.

• Equipment Life Cycle – Dirty coils force compressors to work harder, cutting down their lifespan. If there is too long of a gap between coil cleanings, the compressor can even fail completely, requiring a replacement. Additionally, the built-up grime on the coils can cause corrosion, which requires a coil replacement instead of just a coil cleaning.

• Air Quality – Due to the liquids involved in the air conditioning process, the evaporator coil and condensate pan are breeding grounds for dangerous bacteria, mold spores and fungi. As air comes into contact with the coils, it can absorb these harmful substances on its way. This not-so-fresh air is then blown into the building and is breathed in by the occupants.

How to Minimize the Need for Coil Cleaning Going Forward
Clearly, coil cleaning is a crucial aspect of air conditioning maintenance. In addition to the annual coil cleaning that is recommended, you can advise your customer to take additional preventive action during the year. This can include removing any visible debris that appears on the a/c unit or considering future replacement with specialized coils that are pre-treated at the factory to reduce damage and prevent corrosion.
By performing an annual coil cleaning as part of your customer’s air conditioning maintenance, you can help them enjoy increased energy efficiency and improved air quality.
