Coils in the air handler unit become covered with dirt and grime and it makes the system work much harder to produce the same result. This translates to higher energy costs to cool and heat your building. These coils are typically housed in rooftop units which exposes them to the elements as they work to heat and cool the building. Condenser coils release the absorbed heat outdoors they come directly into contact with the outdoor air which then causes them to become clogged with dirt, grime and debris. The clogged coils limit the efficiency for both energy and cooling. 

Our recommendation is to have the coils cleaned at least every six months and depending on the climate and air pollution in the area they may need to be cleaned more often. We recommend cleaning at the beginning of the cooling season and at the end of the cooling season, before the cooling system starts up and after cooling system shutdown. These measures help refurbish existing machinery and aid in extending the working life of the unit.

Our team is well-versed in coil cleaning and uses a no-rinse formula to get the job done. This allows us to complete the job faster and keep your building cleaner in the process. The no-rinse formula works by breaking down dust and debris, evaporating off the unit when it cleans. We start by turning off the unit to be cleaned and cutting the power to it for safety precautions. We will remove access panels so that we can get into the unit to begin the cleaning process. We will then clean all debris from the coils following NADCA-ACR Standards. Once complete, we will reinstall the access panels, turn the power back on to the unit and restart it for use. Depending on the size and number of units, this process may be half a day or take a week or more. We will give you a schedule estimate upon completion of your inspection.

Coils need to be cleaned at least twice a year, possibly more depending on a variety of other factors such as the part of the country, length of the cooling season, typical cooling season weather and more. It is important to keep up with coil cleaning so that you can avoid unnecessarily high energy costs, lowered lifespan of your equipment, poor air quality and airflow, system failures, expensive repairs due to damage to the system from built-up debris and increased emissions.
