blocked cooling coil, John Herbert energy audit

The above pictured AHU cooling coil was ‘maintained’ by the term Air conditioning contractor. However, during our energy audit we inspected the AHU, dropped the air filters and found that the cooling coil was plugged, approx. 50% of the face area of the coil completely blocked.

Cleaning the cooling coil will restore lost energy efficiency, and improved comfort conditions in the space.
