What did the Rancho Cucamonga home furnishings store need replaced on its roof?
A national home furnishings store in a busy Rancho Cucamonga shopping center needed a group of packaged rooftop units replaced in one mobilization, with shared parking and neighboring tenants all around the building.
This national home furnishings store anchors part of a busy Rancho Cucamonga shopping center, with neighboring tenants, shared parking and landscaped islands all around the building. Its sales floor is cooled by multiple packaged rooftop units, and a group of them was being replaced at once.
Replacing several units in one mobilization is efficient, but it raises the stakes on planning. The crane is booked once, the new equipment arrives together on one trailer, and every unit has to come off and go on in a sequence that keeps the work moving and the shopping center usable.
What did the Rancho Cucamonga multi-unit changeout include?
The Rancho Cucamonga scope was a multi-unit changeout: set up the crane in the shopping center lot, receive a trailer of new units, swap each existing unit for a new one, and make up electrical connections.
- Set up the crane in the shopping center lot and brief the crew before lifting
- Receive a flatbed trailer of new packaged rooftop units
- Rig existing units off their curbs and fly them down
- Fly each new unit up, set it on its curb and align it
- Make up electrical connections at the new units
How did REE sequence each rooftop unit swap in Rancho Cucamonga?
REE Mechanical Inc. confirmed the lift plan before the first pick, then repeated one sequence per unit: strap and fly the old unit down, fly the new one up, align it on its curb, and wire it.
The first photo is the crew in hard hats and high-visibility vests watching the crane set up in the parking lot. That pause before the first pick is where the lift plan gets confirmed: who is on the roof, who is on the ground, where the trailer sits and which unit goes first. Behind them, the flatbed carries the new packaged rooftop units for the day.
On the roof, the sequence repeats. An existing unit is strapped with yellow lifting slings, lifted clear of its curb and flown down. A new unit comes up on the same line and the crew guides it onto the open curb, with technicians on each side lining it up as it lands. Several frames show the crew kneeling at the curb to check the fit before the unit is released. Once set, a technician works inside the unit's electrical compartment to make up the connections.
That rhythm is the core of a rooftop unit installation and replacement done by a self-performing crew. If parts or equipment had been delayed, our temporary cooling arrangement through Herc Rentals is how we keep a store trading in the meantime.
What did the Rancho Cucamonga store's roof look like when the changeout ended?
The Rancho Cucamonga record ends with new packaged units set on their curbs across the roof. Tonnage, dates and cost are not published because the client is under NDA.
The final frames show the crane lowering the last units over a roof of new equipment set on their curbs, with the mountains behind the shopping center. We do not publish tonnage, dates or cost for this site; the client is under NDA, and we will not substitute invented numbers for real ones.
With a group of new units installed at once, this is a natural point to tag every asset and start fresh maintenance records. That is what our HVAC asset inspection and testing is for. More on this region on our San Bernardino County page and nearby Ontario page.
