Why was the Coachella Valley department store's rooftop replacement complex?
A Coachella Valley department store needed large packaged rooftop units replaced inside a rooftop screen wall, set well back from the roof edge, in some of the hardest cooling conditions in Southern California.
A department store in the Coachella Valley has two things working against its rooftop equipment: some of the hardest cooling conditions in Southern California, and a customer experience that does not tolerate a warm sales floor. The store's large packaged rooftop units sit inside a screen wall on the roof, which keeps them out of sight from the street but also boxes them in.
Units of that size, set back behind a screen and well in from the roof edge, need more reach than a standard truck-mounted crane provides. That shaped the whole job.
What did the Coachella Valley rooftop unit replacement include?
The Coachella Valley scope covered coordinating a third-party lattice-boom crane assembled on the street, coning off the roadway, and flying large units out of and into the screened rooftop enclosure.
- Coordinate a third-party lattice-boom crane, assembled on the street beside the store
- Cone off the roadway around the crane and assembly area
- Rig large packaged rooftop units inside the screened enclosure
- Fly existing units out and new units in over the screen wall
- Work the units into position within the enclosure
How did REE time the Coachella Valley lift around the desert heat?
The crane company assembled its lattice boom on the street at sunrise, and the REE Mechanical Inc. crew rigged and guided each large unit inside the screen wall before the afternoon desert heat built.
The photos begin at sunrise with the crane truck arriving and the lattice boom sections laid out along the street for assembly. A lattice-boom crane is built on site piece by piece, so the street around it was coned off while it was assembled. Starting early in the desert is practical, too: rooftop work is safer and steadier before the afternoon heat builds.
Up top, the crew worked inside the screen wall, rigging large packaged units with lifting straps, working along the length of each unit and keeping it clear of the screen as it moved. One frame shows a unit flown high on the lattice boom against a clear desert sky; others show new units in place inside the enclosure with the mountains beyond.
Planning a lift like this is part of every rooftop unit installation and replacement we scope: equipment size, crane reach, screen clearance and street logistics come before anything is ordered. In desert markets, we pair that with a coil and condenser maintenance and tune-up plan, because dust and heat work against condenser performance all season.
What did the Coachella Valley department store's roof look like at the end?
The Coachella Valley job ends with large new packaged units set inside the rooftop enclosure. The store's name, tonnage, dates and costs stay unpublished under NDA.
The record ends with large new packaged units set inside the rooftop enclosure. The department store is under NDA, so we are not publishing its name, tonnage, dates or costs, and we will not fill that gap with invented figures.
For equipment this size, long-term value comes from what happens after the crane leaves: a preventive maintenance and tune-up program scoped to ANSI/ASHRAE/ACCA Standard 180. See our Riverside County coverage for more on the region.
