Short answer: Commercial HVAC replacement in North Las Vegas makes sense when a rooftop or packaged unit is past 15 years old, still runs R-22 refrigerant, or has repair bills climbing faster than its remaining value. The Cooling Company assesses your existing units, recovers and disposes of old refrigerant, cranes down the failed equipment, recalculates the load so the new system is right-sized for how the building is used today, and schedules the swap after hours or in phases so distribution lines, manufacturing cells, and retail floors keep running. Call (702) 567-0707.
North Las Vegas runs on big roofs. The Apex Industrial Park, the fulfillment and distribution warehouses off the I-15 corridor, the light-manufacturing bays near Cheyenne, and the busy retail strips along Craig Road all carry large rooftop units (RTUs) and packaged equipment that have been working through brutal desert summers for a decade or more. When those legacy units start failing, a like-for-like patch is rarely the right call. Replacement done correctly is a capital decision that can cut energy spend, end the parts chase, and remove the risk of a mid-July outage. We have served Southern Nevada since 2011, and we approach every commercial replacement as an engineering project, not a swap-and-go.
When to replace an aging commercial unit instead of repairing it
Repair is the right answer for a young, healthy unit with an isolated failure. Replacement becomes the smarter spend when several of these signals stack up at once:
- Age past its service life. Commercial rooftop and packaged units typically deliver dependable service for around 15 to 20 years in the Las Vegas climate. Past that, compressors, coils, and cabinets are all aging together, so fixing one component just exposes the next.
- R-22 refrigerant. R-22 production and import ended, so any unit still charged with it depends on a shrinking, expensive reclaimed supply. A single significant leak repair on an R-22 system can cost more than the unit is worth, and there is no long-term fix. Upgrading to a current-refrigerant system removes that dependency permanently.
- Repair costs climbing toward replacement value. When the annual repair total starts approaching a meaningful share of a new unit, you are paying premium prices to keep an obsolete asset limping. We give you the honest math so the decision is grounded, not guessed.
- Efficiency decline. An old unit rated at a low EER quietly costs more to run every year as coils foul and compressors lose capacity. On a large North Las Vegas footprint, that drift shows up as real money on the NV Energy bill.
- Comfort and capacity complaints. Hot zones in a warehouse, a retail floor that never cools down by midday, or a manufacturing area fighting heat load are signs the existing equipment can no longer meet demand.
If you are weighing repair against replacement, we will inspect the equipment, document its real condition, and tell you which path actually protects your budget. If a unit has years of safe life left, we will say so.
Assessing your existing rooftop and packaged units
Replacement planning starts on the roof. North Las Vegas warehouse and big-box roofs often carry multiple large RTUs, sometimes from different eras and different manufacturers, mounted on curbs that were set when the building was constructed. Before we quote anything, we document what is actually up there: tonnage, refrigerant type, voltage and electrical service, curb dimensions, ductwork connections, and the structural path for getting old equipment down and new equipment up.
We also look at how the building is used now versus when those units were installed. A space that was once open warehouse may now hold racking, refrigerated zones, or added office build-out, all of which change the cooling load. That gap between the legacy equipment and the building's real needs is exactly why right-sizing matters on replacement.
Removing and disposing of the old equipment
Pulling a large commercial unit is a regulated, logistics-heavy job. We handle the full removal cleanly:
- Refrigerant recovery. Old refrigerant, including R-22, is recovered and handled according to EPA requirements. Nothing gets vented.
- Crane-down of large RTUs. The big packaged units common on North Las Vegas warehouse roofs come down by crane. We coordinate the lift, the staging area, and the roof protection so the building envelope and parking flow stay intact.
- Responsible disposal. The retired equipment is hauled and recycled properly, with metals and components routed to the right channels rather than dropped in a dumpster.
Matching new units to existing curbs, ductwork, and electrical
The fastest, cleanest replacements reuse what already works. Where a new unit footprint differs from the legacy one, we use adapter curbs so the replacement seats correctly without rebuilding the roof penetration. We retrofit duct connections and transitions so the new equipment ties into existing distribution, and we verify the electrical service, disconnects, and breaker sizing match the new unit's draw. This retrofit-first approach keeps the project shorter, reduces roof work, and lowers cost compared with re-engineering the whole connection.
Right-sizing on replacement
The single biggest mistake in commercial replacement is assuming the old tonnage is the correct tonnage. Legacy North Las Vegas warehouse units were frequently oversized, undersized, or simply installed for a use the building no longer serves. We perform a fresh load calculation following Manual N for commercial buildings, accounting for current occupancy, equipment heat load, insulation, glazing, and how the space is actually operated. The result is a system matched to real demand, which means tighter temperature control, fewer short cycles, and lower operating cost than the unit it replaced.
Phased and after-hours swaps that keep operations running
Distribution centers, fulfillment warehouses, and manufacturing lines in North Las Vegas often run around the clock and cannot simply stop while equipment is changed out. We plan replacements around your operation rather than the other way around. That can mean after-hours and overnight crane work, weekend cutovers, or a phased sequence that replaces units zone by zone so part of the facility always stays conditioned. We coordinate roof access, crane windows, and electrical shutdowns with your site team in advance so production, shipping, and the retail floor keep moving.
The capital-replacement ROI on large North Las Vegas footprints
On a small building, the efficiency gap between old and new equipment is minor. On a 100,000-plus-square-foot warehouse or a multi-unit retail center, it is substantial. Moving from a worn, low-EER legacy unit to a modern high-IEER system meaningfully reduces the cooling energy a large footprint pulls during the long Las Vegas cooling season. Combined with the end of R-22 service costs and emergency repair calls, a planned replacement often pays back through lower operating expense and predictable budgeting. We build the assessment so you can make the capital case with real numbers from your own equipment, not generic claims.

Frequently asked questions
How do I know whether to replace or just repair my commercial unit?
Look at age, refrigerant, and repair history together. A unit past 15 years old, still running R-22, or racking up repair bills that approach a real share of a new unit's cost is usually better replaced than repaired. We inspect the equipment, document its true condition, and give you the honest math so the decision is grounded rather than guessed.
Do you have to replace the curb and ductwork when you swap a rooftop unit?
Usually not. We use adapter curbs to seat a differently sized new unit on the existing roof opening and retrofit the duct transitions so the new equipment ties into your current distribution. Reusing what already works keeps the project shorter and lowers cost. We only rebuild a connection when the existing one genuinely cannot serve the new unit safely.
Will replacing my rooftop unit shut down my warehouse?
No. We plan replacements around continuous operations. That can mean after-hours or overnight crane work, weekend cutovers, or a phased sequence that swaps units zone by zone so part of the facility always stays conditioned. We coordinate the schedule with your site team so shipping, production, and the retail floor keep running.
Why do you recalculate the load instead of matching the old unit's size?
Because the old size is often wrong. Legacy North Las Vegas units were frequently oversized or undersized, and many buildings are used differently now than when the equipment went in. We run a fresh Manual N load calculation so the replacement matches real demand, which means better temperature control, fewer short cycles, and lower operating cost.
What happens to the old refrigerant and equipment?
We recover all refrigerant, including R-22, in line with EPA requirements so nothing is vented. The retired unit is craned down and hauled for proper recycling, with metals and components routed to the right channels rather than landfilled.
