Coils trap dust, soil, grime and other deposits that act as a blanket to reduce the heat transfer efficiency. This buildup interferes with proper system operation because air can't pass through the coil properly which reduces efficiency and shortens system life.
Here is an example of damage caused by improper cleaning.
Damaged coils restrict airflow and decrease efficiency.
Our coil cleaning process:
Both sides of the coil are vacuumed using a HEPA (high-efficiency particulate arresting) vacuum to remove any large surface debris.
A need-specific coil cleaner is applied to both sides of the coil bank and is allowed to penetrate for the recommended amount of time. The cleaner foams and brings debris caught in the fins to the surface.
The coil is rinsed to remove the cleaner and any remaining debris.
