Coil Cleaning

Are certain rooms in your business receiving less heat or cold air than others?

Heating and cooling coils may be blocked with dirt and debris. If not equipped, we can install cam-lock doors on each side of coils to allow you to inspect them on a routine maintenance schedule.

Do you have a routine cleaning schedule for air handler unit coils? It is typically a “self-liquidating decision” to clean coils on a six month schedule because of energy savings and prolonged coil life.

How do we clean your coils?

CLEANING OF COILS - Any cleaning method may be used which will render the Coil Visibly Clean and capable of passing Coil Cleaning Verification. The following is a typical coil cleaning procedure:

1. Turn off and lock out the main power switch to the unit and open all access panels.

2. Record any pre-existing damage. We are not responsible for problems resulting from prior careless/inappropriate cleaning techniques of others.

3. Remove Surface Loaded Fibers. If applicable, use a HEPA vaccum with a soft brush. A soft non-metallic bristle brush may also be used. The tools are to be applied in the direction of the fins.

4. Wet finned surfaces with clean water and a low velocity garden hose.

5. Mix coil cleaner as required with 100-degree water.

6. Thoroughly apply to all coil surfaces including finned area, tube sheets and coil headers. Spray in a vertical, up-and-down, motion ensuring the coil cleaner thoroughly penetrates into the fins.

7. Cleaning solution should remain ‘wet’ on fins for 5-10 minutes (reapply as necessary).

8. Thoroughly rinse surfaces with low velocity clean water in a vertical, up-and-down motion. Back flush towards the entering airside of the coil.


POST PROJECT REPORT - At the conclusion of the project, the Contractor shall provide a report to the owner indicating the following:

1. Success of the cleaning project. This is verified through visual inspection and/or gravimetric analysis.

2. Any known areas of the system found to be damaged and/or need of repair.
