PC Air Handling Unit Replacement

24 June 2025

Item No. 8d supp

Meeting Date: June 24, 2025

• 16 Air Handling Units (AHUs) have

burst heating coils. These provide

heating to the aircraft during winter

operations.

• Gates with burst coils include: A9, B1,

B3, B6, B7, B8, B10, B11, B12, B14,

B15, D1, D3, D8, S2, S10 (widebody).

• Replace and refurbish the 16 AHUs

identified as soon as possible, so

aircraft do not need to run jet-fuel

powered aircraft auxiliary power units

while parked at gates.

Gates Affected

• Multiple freeze events contributed to

current heating coil failures (not end of

life). The units are still able to provide

cooling.

• This project restores heating at 16 gates as

soon as possible. Separate from this

project, work continues to identify

solutions to improve PC Air cooling

system-wide.

• A future project is currently being

developed that will consider wholistic

changes to the PC Air system to include

freeze mitigations, programming

adjustments, and a host of infrastructure

and AHU upgrades
