3- to 10-ton light commercial rooftop units
The right size for high comfort.
The lowest installed cost and lowest total
Most Trane Precedent
rooftop units can be
ready in as few as two
weeks—the fastest
delivery time in the
industry—so your
project doesn’t get
delayed while waiting
for equipment.
When it comes to HVAC expenses, every dollar counts. From
your initial investment to monthly utility costs and maintenance,
a light-commercial rooftop unit can have a significant impact
on your bottom line—which is why a Trane® Precedent™ lightcommercial rooftop unit can be the perfect choice.
No competing light-commercial rooftop unit has a lower installed cost than
the Trane Precedent—and with its industry-leading efficiency and low
maintenance requirements, no other unit has a lower total cost of ownership.
And once you’ve made the wise decision that a Trane Precedent lightcommercial rooftop unit is the right solution for your building, it’s good to
know that no other light-commercial rooftop unit can be delivered as quickly
as the Trane Precedent, with most units ready in as few as two weeks—order
to ship.
The lowest costs. The highest efficiency. The fastest delivery time. For all
these reasons and more, a Trane Precedent light-commercial rooftop unit
isn’t just the perfect choice—it’s the only choice to extend the life of your
building and improve the lives of those within it.

Hot gas reheat (Not shown)
Heat energy is recycled from the compressor to reduce
indoor air humidity, eliminating the need for a separate
heat source to do the job—which saves energy and money.
Maintaining proper indoor humidity levels improves indoor
