Commercial Temporary Cooling Rental & Setup in Southern California

What is temporary cooling rental and setup for a commercial site?

Temporary cooling rental and setup puts rental equipment in place to keep a commercial space cool while the permanent repair or replacement is pending. It ranges from a single spot cooler in a stockroom to larger units ducted into a sales floor.

REE Mechanical Inc. has teamed up with Herc Rentals to provide it. The rental is there to bridge a gap, so a store can keep trading at reduced comfort instead of closing while it waits on a part or a new unit.

When is temporary cooling worth arranging?

Arrange it when the space cannot go without cooling and the permanent fix is days or weeks away, because of a back-ordered part, a long equipment lead time, or a heat event the remaining units cannot handle.

• A compressor, coil, or control board is on back order and the unit cannot run without it.
• A replacement rooftop unit is on order but has not shipped.
• A heat wave is pushing the surviving units past what they can hold.
• A planned replacement or crane lift will leave part of the building without cooling for a stretch.
• A critical room, such as a network closet, pharmacy area, or refrigerated stockroom, cannot be left warm while the main unit is down.

Across the inland valleys and the high desert, long summer heat makes a lead-time problem far more likely to become a closure.

How does REE Mechanical work with Herc Rentals?

You choose how involved we are. We can oversee the whole process, installation and removal included, or connect you with the Herc team member nearest your facility if you would rather contract it yourself.

Either way, the diagnosis drives the rental. What failed, which space is affected, and how long the parts are likely to take decide what equipment goes in and for how long. Vanny Weber, our Scheduling and Operations Lead, gets that first diagnostic call on the board and a technician moving.

What kinds of rental cooling equipment are used?

The choice depends on the size of the space and how long coverage is needed. Small rooms take a portable spot cooler; a sales floor usually needs larger equipment placed outside and ducted in.

Equipment	Fits	Planning point
Spot cooler	Stockroom, office, network closet	Warm exhaust has to be ducted out of the space
Larger portable or trailer-mounted unit	Sales floor or large open area	Placement outside and a duct path through a door or opening
Supplemental unit	A space whose rooftop unit is struggling but running	Sized to add capacity, not replace the unit

What has to be planned before the equipment arrives?

Power, condensate, placement, and removal should all be settled before delivery. A rental that arrives without those answers tends to sit on the dock while the space stays warm.

• The cooling load of the affected area, so the equipment matches the space.
• The power source: available building circuits or a separate generator.
• Where condensate goes and, for spot coolers, how hot exhaust air leaves the room.
• Placement and duct routing that keep exits, aisles, and fire equipment clear.
• Delivery and setup timed around trading hours.
• A removal date tied to the permanent repair.

How does the rental run alongside the repair?

Temporary cooling runs in parallel with the permanent fix. It goes in once the lead time is known and comes out when the repaired or replacement unit is running again.

1. The technician diagnoses the failure and confirms the parts or equipment lead time.
2. Jessica Bresciani, our Estimating Operations Lead, turns the findings into a quote for the permanent repair or replacement.
3. The rental is scoped for load, power, condensate, placement, and duration.
4. Equipment is delivered and set up, ideally outside trading hours.
5. The permanent repair or replacement is completed once parts arrive.
6. Rental equipment is removed and the work order is closed out.

Why do temporary cooling plans fall apart?

Temporary cooling plans fall apart when sourcing starts from zero during a regional heat event, when nobody scoped power or placement, or when nobody planned the removal date.

The first is the hardest to fix in the moment, because a heat event sends every facility manager in the region looking for the same equipment at once. An existing rental relationship is the planning answer. The last one is the most avoidable: without a removal date, rental charges keep running weeks after the permanent repair is done. Tracking the rental on the same work order as the failed unit lets your facilities desk see which sites are on temporary cooling and when each is due to come off.

What safety points apply to temporary cooling?

Temporary equipment must never block exits, aisles, or fire equipment, and its electrical load has to suit the circuit or generator feeding it. Generator use and fuel storage can carry local requirements.

Check with the local jurisdiction and your landlord before a generator goes on site. REE Mechanical Inc. is licensed, bonded and insured, and our technicians are factory-trained.
