AHU 1 (ceiling above office)
AHU 2 Roof-top unit #2
AHU 3 (Closet)
A total of three air handlers were inspected, cataloged and cleaned. Please refer to chart 5 for inspection and cleaning checklist.
Air Handler Unit 1 (AHU 1) was found secured above the ceiling in manager's office. This unit was in good working order. Drip pan contained excessive dust and construction debris, but was dry and free of any biological contaminants. Refer to chart 2 for review system specs and AHU #1 slide deck photos (above).
AHU 2 roof unit and its respective thermostat were not in working order. This unit has a broken/unattached pulley belt which had cut electrical wires upon failure. See chart 3 for system specs and slide-deck photos.
AHU 3 within the mechanical closet was in working order but has a leak resulting from a broken condenser connector. This unit was wet with a relative humidity of 23% within the unit itself. Water was passively spilling to the floor which was resulting in moisture wicking to items stored within the mechanical closet. Please refer to chart 4 for system specs and photo slide deck.
1. Repair Roof top AHU #2, belt & electrical wiring
2. Repair AHU 3 condenser tube attachment
3. Decommissioned roof top unit could be removed (shown in roof-top photo slide-deck above).
4. Replace two stained ceiling tiles in offices
Outside Condenser Units
Two ground-level outside air conditioning condenser units were inspected and cleaned. A third roof-top unit was inspected and coils were cleaned. Refer to slide-deck.
- A moderate amount of debris, mostly leaves, was found in each ground-level system. All debris was removed and unit vacuumed. Coils were cleaned with HVAC Coil System Cleaner. Aluminum fins were re-positioned (combed) back to optimum working position.
The area surrounding the concrete pads should be free of debris, particularly bark mulch.
Infra-red thermal imaging was employed to test for breaks in the system. Excluding two small repairs as noted above, the system was sealed efficiently.
