Air systems
Protect airflow and indoor comfort with coordinated checks of filters, coils, fans, dampers, drainage and controls.
The equipment
An air handling unit conditions and moves air through a building using filters, cooling coils, fans, dampers and controls. Restricted airflow, dirty heat-transfer surfaces or mechanical and control faults can reduce comfort and place extra demand on the wider cooling system.

Diagnosis before decisions
