McKenney's replaced nine chilled water coils in air handling units located in an operations center for a public service company. The project had to be completed during limited weekend windows to avoid downtime. New custom drain pans were also fabricated to fit inside the existing pans and support the replacement coils. The project was finished on time and on budget, allowing the air handling units to now run more efficiently and save energy costs.

cKenney’s replaced nine
chilled water coils in 34-year-
old air handling units (AHUs)
located in an operation center for a large,
public service company.
THE CHALLENGE
The facility required zero downtime during
occupied hours, which gave the team
only 30 hours on weekends to complete
the project. The AHUs overhaul took place
in small, 200-square-foot mechanical rooms
and the team knew it had to act quickly
and decisively as it worked alongside other
trades. In addition, an awkward piping
configuration restricted prefabrication work
and the condition of the area under the coils
was unknown.
THE SOLUTION
With design plans and detailed schedules
in place, the McKenney’s team accelerated
AHU replacements. New custom-built
stainless steel drain pans were also fabricated
to fit inside the existing pan to support the
weight of the replacement coils.
THE RESULTS
The project was completed on time and
on budget. The AHUs are now running
more efficiently, saving energy and opera-
tional costs.
