Short answer: When a commercial system in Paradise is past its service life, leaking R-22, or losing efficiency every season, replacement is usually cheaper over five years than chasing repairs. The Cooling Company assesses your existing rooftop or chiller equipment, right-sizes the replacement with a fresh Manual N load calculation, reuses your curbs and ductwork where it makes sense, and schedules phased or after-hours swaps so high-occupancy buildings near the Strip, the Convention Center, UNLV, and the airport keep running.

Paradise is the unincorporated township that holds most of the Las Vegas Strip, the Convention Center, UNLV, Harry Reid International Airport, and the Sunrise and UMC medical corridor. That footprint means a heavy concentration of older, high-occupancy buildings: hospitality-adjacent properties, mid-century office towers, medical office buildings, and commercial blocks that have cooled Las Vegas heat for decades. A lot of that equipment is now at or past end of life, and replacing it correctly is a very different job than installing a system in a new shell.
When to replace instead of repair
Repairing a commercial unit makes sense right up until it doesn't. The honest break point is usually a combination of age, refrigerant, and the trend line on your repair invoices. A few signals that point firmly toward replacement on a Paradise property:
- Age past the service window. Most commercial rooftop units and split systems are engineered for roughly 15 to 20 years of Las Vegas duty. Our climate is brutal on compressors and coils, and units running long, hot cooling seasons age faster than the brochure suggests. Past that window, you are buying time, not reliability.
- R-22 in the system. R-22 has been phased out of new production. There is no fresh supply, only reclaimed refrigerant at steadily climbing prices. If your aging unit still runs R-22 and it springs a leak, you are paying a premium to recharge a system that is already obsolete. That math almost always favors replacement with a modern R-410A or R-454B platform.
- Efficiency decline you can measure. Older equipment loses capacity as coils foul, compressors wear, and components drift out of spec. If your energy bills keep climbing while the building stays the same, you are paying for that decline every month. A right-sized, modern high-efficiency unit recovers a meaningful share of that loss.
- Repair costs stacking up. When a single repair approaches a large fraction of replacement cost, or when you are calling for service two or three times a season, the repair path has quietly become the expensive one.
- Comfort and humidity complaints. Hot spots, long recovery after a busy lunch rush, and stuffy conference rooms often signal the system can no longer hold the load it was sized for years ago.
We will tell you plainly when a targeted repair is the smarter move. The goal is the lowest total cost of ownership over five years, not the biggest invoice today.
Assessing your existing high-capacity equipment
Paradise's older high-occupancy buildings often run high-capacity rooftop package units, split systems feeding multiple zones, or central chiller plants serving an entire structure. Before we quote anything, we assess what is actually on your roof or in your mechanical room. That includes the condition of the existing curbs, the layout and integrity of the ductwork, the available electrical service, and how the current equipment is staged and controlled.
This assessment matters because the wrong assumption is expensive. A replacement that ignores a corroded curb, undersized electrical, or duct restrictions either fails inspection or underperforms from day one. We document existing conditions so the plan reflects your real building, not a generic spec sheet.
Removing and disposing of old equipment on tight Strip-corridor sites
Getting the old unit off the building is half the job, and on Paradise sites it is rarely simple. Refrigerant has to be recovered and handled per EPA rules before anything comes down. Heavy rooftop equipment usually needs a crane, and crane logistics on the Strip corridor mean tight setbacks, limited staging, pedestrian traffic, valet and rideshare lanes, and buildings that sit shoulder to shoulder with neighbors.
We plan the lift before the swap day: confirm the crane footprint, coordinate permits and lane control, time the work to avoid peak traffic where we can, and stage the new unit so the old one comes off and the new one goes up in one controlled sequence. Old equipment is hauled off and disposed of properly, with refrigerant reclaimed rather than vented. You are left with a clean roof and a working system, not a logistics headache.
Matching to existing curbs, ductwork, and electrical
The fastest, least disruptive replacements reuse what is already good. Where your existing roof curb is sound, we match the replacement unit to it or fabricate a transition curb adapter so we are not cutting new roof penetrations and reworking the membrane. Where your ductwork and electrical service are adequate, we tie into them rather than tearing them out.
That said, we never force a match that compromises performance. If the old ductwork is choking airflow, if the electrical can't support a modern unit's draw, or if a curb is too far gone to trust, we say so and price the fix. Reusing infrastructure should save money, not lock in the problems that aged out the old system.
Right-sizing with a fresh Manual N load calculation
One of the most common mistakes in commercial replacement is swapping like-for-like by tonnage without checking whether the original size was ever right, or still is. Buildings change. Occupancy shifts, interior buildouts move walls, equipment loads change, and the original sizing may have been padded or guessed.
We run a fresh ACCA Manual N commercial load calculation rather than copying the nameplate of the dying unit. Oversized equipment short-cycles, struggles with humidity, and wears out early. Undersized equipment runs flat out and never catches up on a hot Paradise afternoon. Right-sizing gets you steady, efficient operation and a unit that lasts. It is the single biggest lever on both comfort and long-term cost.
Phased and after-hours swaps for buildings that cannot close
Hospitality-adjacent properties, 24/7 operations, medical office buildings near Sunrise and UMC, and high-occupancy offices along the Convention Center and UNLV corridor often cannot simply shut down for a multi-day replacement. We plan around that reality.
Depending on the building, that means after-hours and overnight work to keep occupied spaces comfortable during business hours, phased replacement that swaps units zone by zone so part of the building always has cooling, and temporary cooling staged for sensitive spaces while a unit is down. We sequence the work so guests, patients, tenants, and staff feel as little as possible. The point is to make the building better, not to take it offline while we do.
Capital-replacement ROI and redundancy upgrades
A commercial replacement is a capital decision, and we treat it like one. We help you weigh the swap cost against the efficiency you recover, the repair spending you stop, and the risk you retire when an end-of-life unit finally quits in July. For many older Paradise buildings, the monthly energy savings and the end of emergency repair calls change the payback math meaningfully.
Replacement is also the right moment to design in redundancy. If a single failure currently takes your whole building offline, we can stage the swap so critical zones have backup capacity, or split a large load across units so no one failure shuts you down. For medical, hospitality, and any operation where an outage costs real money, building that resilience in during a planned replacement is far cheaper than retrofitting it later.

How do I know whether to replace or repair my commercial unit?
The honest test is total cost over the next five years. If your unit is past its service life, running R-22, losing efficiency, or stacking up repair bills, replacement usually wins. We assess the equipment, show you the numbers, and recommend the path with the lowest long-term cost rather than the biggest invoice today.
Can you replace our rooftop units without closing the building?
In most cases, yes. We use after-hours and overnight work, phased zone-by-zone swaps, and temporary cooling where needed so occupied spaces stay comfortable during business hours. We plan the sequence around your operating schedule before the swap day so high-occupancy and 24/7 buildings keep running.
Why does R-22 push a system toward replacement?
R-22 is no longer produced. Only reclaimed supply remains, and its price keeps climbing. If an aging R-22 unit leaks, recharging it costs a premium to keep obsolete equipment alive. Replacing it with a modern R-410A or R-454B system ends that exposure and recovers efficiency at the same time.
Will you reuse our existing curbs and ductwork?
Where they are sound, yes. Reusing a good curb avoids new roof penetrations, and tying into adequate ductwork and electrical keeps cost and disruption down. Where the existing infrastructure would compromise performance, we tell you plainly and price the fix rather than locking in the problems that aged out the old system.
How do you handle crane work on tight Strip-corridor sites?
We plan the lift before the swap day. We confirm the crane footprint, coordinate permits and any lane control, time the work around traffic where possible, and recover refrigerant and haul off the old equipment properly. The new unit is staged so the old one comes down and the replacement goes up in a single controlled sequence.
