Rooftop equipment, set and commissioned without shutting a building down

Chapter 01
A packaged rooftop unit fails differently than a house does
A residential split system gives you a condenser in the yard and an air handler in a closet. Commercial packaged equipment puts the whole system, compressor, coil and blower, in one cabinet on the roof, feeding the building through curbs and ductwork nobody inside ever sees. When it goes down, the building manager does not get a quiet corner of the house that stops working. They get a floor, a suite, or an entire tenant with no cooling at all, on the manager's schedule, not ours.
That is what a commercial contract has to solve for. The repair has to fit the building's hours, its roof access, and whatever else is already running up there.

Curbs, rigging and a crane, done as one job
Our own photographs show the work end to end. A RUUD Commercial Series packaged unit gets slung and lifted by crane from ground level, set onto the existing curb, and tied into the building's ductwork and controls. On one north Houston job we set and commissioned five units on a single roof in a day, and on another we lifted a new unit onto the curb beside the Carrier equipment it was replacing.
Aaron Mechanical's mission statement covers design, fabrication, installation and service, and commercial rooftop work draws on all four: fabricating transition ductwork and curb adapters on site when a replacement unit does not match the old footprint exactly, rather than bolting on a stock part and hoping it fits.
Chapter 03
Why the paperwork matters as much as the crane
A property manager signing off on rooftop work is exposed if the contractor on the roof is not properly covered, so Aaron Mechanical carries $2,000,000.00 in liability coverage and holds Texas license TACLA023312C. Owner Merle Aaron Jr. sits on the RUUD Product Panel and the Century Supply Dealer Council, serves on the Texas ACCA board, and is a past President of the Houston ACCA chapter, credentials that come from doing this kind of commercial work long enough to be asked onto them.
Refrigeration and ventilation are part of the same mission statement as air conditioning and heating, so a rooftop scope that also touches walk in coolers or exhaust and makeup air stays inside what we actually do, rather than getting handed off to a second contractor. Call the office to talk through a specific building before the crane gets booked.

On the roof
Two frames from the same changeout
The unit comes off the ground on crane slings, then lands on the curb above the occupied building beneath it. Both photographs are from real Aaron Mechanical commercial jobs in north Houston, not stock.
Most rooftop equipment sits next to a system already running the building, so we plan the lift and the changeout together instead of two separate visits. Ask about a maintenance agreement for the equipment once it is set, or see what we install on the air conditioning and heating pages. For coverage questions before you sign off on the work, see our guarantees or contact the office.
