Commercial HVAC Replacement Las Vegas, NV
Short answer: Commercial HVAC replacement in Las Vegas is the right call when repair costs exceed 50% of replacement value, when a system runs R-22 refrigerant (now production-banned), or when age and efficiency losses are raising your operating costs. We handle the full scope: load calculation, permitting, equipment procurement, removal of the old unit, and installation with minimal disruption to your operations.
When to Replace, Not Repair
Property managers and facility decision-makers face a clear decision threshold: at some point, continued repair spending on an aging system costs more than a planned replacement. In Las Vegas, commercial systems reach that threshold faster than the national average. Summer heat runs equipment harder, refrigerant leaks increase with age, and R-22 refrigerant (still found in systems installed before 2010) is now available only as expensive recycled stock.
The practical benchmarks for replacement:
- Annual repair costs exceed 30-50% of replacement cost
- System age is 15+ years (commercial rooftop units average 15-20 years in moderate climates; in Las Vegas, expect 12-17)
- System uses R-22 refrigerant, which is no longer manufactured and costs $50-$150/lb for recycled supply
- Capacity has degraded: the unit can no longer maintain setpoint during peak summer hours
- Multiple compressor failures or a failed heat exchanger on a gas heating section
- Tenant or employee comfort complaints that are persistent and not resolved by repairs
What We Replace
Packaged Rooftop Units (RTUs)
The most common commercial HVAC system in Las Vegas. Rooftop units consolidate the entire HVAC system in one self-contained package, making swap-outs straightforward for a licensed contractor. We remove the existing unit, inspect and repair the curb (the roof mounting frame), and install the new unit with reconnected ductwork, electrical, and controls. One-day replacement is typical for standard tonnage units.
Split Systems
Commercial split systems separate the condensing unit (outdoor) from the air handling unit (indoor). Common in smaller commercial spaces, strip malls, and professional offices. Replacement involves removing and disposing of both components and installing matched replacement equipment calibrated to the building's load requirements.
VRF/VRV Systems
Variable refrigerant flow systems serve multiple zones from a single outdoor unit. Replacement or expansion of VRF systems requires matching refrigerant type and system generation. We assess existing infrastructure before recommending full replacement versus partial system upgrades.
Dual-Fuel and Hybrid Systems
Some larger commercial applications use dual-fuel configurations pairing electric heat pumps with gas backup. We handle replacement across all commercial heating configurations, including gas furnace sections in packaged rooftop units.
Our Commercial Replacement Process
- Site assessment and load calculation: We measure the actual thermal load of your space, not just match the existing tonnage. Many commercial replacements are the opportunity to correct an oversized or undersized system installed years ago.
- Equipment recommendation: We recommend replacement units matched to your efficiency targets, refrigerant type (R-410A or R-32/R-454B for newer equipment), noise constraints, and budget. We provide options at multiple efficiency tiers with honest payback analysis.
- Permitting: Commercial HVAC replacement requires a mechanical permit in Clark County. We pull the permit, schedule the inspection, and handle the closeout. Never work with a contractor who skips permits on a commercial job.
- Scheduling around your operations: We coordinate replacement timing to minimize disruption. For retail and hospitality, early morning or overnight installs are available. For office buildings, planned weekend or after-hours work is standard.
- Removal and disposal: We remove and dispose of the old unit per EPA regulations. R-22 refrigerant must be recovered by a certified technician before disposal; we handle this as part of the job.
- Installation and commissioning: The new unit is installed, wired, charged with refrigerant, and commissioned. We verify airflow, temperature differentials, and controls before sign-off.
- Post-installation support: We register the manufacturer warranty, provide documentation for your maintenance records, and set up any smart controls or BMS integration.
Why Las Vegas Commercial Replacements Are Different
Commercial HVAC replacement in Las Vegas involves challenges not typical in other markets:
- Peak capacity requirements: Equipment must be sized for 115-120°F ambient conditions, not standard 95°F test conditions. Systems rated at nominal capacity in a lab may be running at 80-85% capacity in July in Las Vegas. Proper load calculation accounts for actual peak conditions.
- Roof access and equipment weight: Many Las Vegas commercial properties have low-slope flat roofs with utility penetrations. Crane access, roof weight limits, and curb compatibility must be assessed before equipment is ordered.
- Tight timelines in summer: A commercial system failure in July cannot wait for a multi-week lead time. We maintain relationships with distributors to prioritize replacement equipment. For critical failures, we can provide temporary cooling while replacement equipment is procured.
- R-22 system transitions: Properties with R-22 systems cannot simply recharge. Replacement with modern R-410A or R-454B equipment eliminates ongoing refrigerant cost exposure and brings the system into current code compliance.

Frequently Asked Questions
How long does a commercial HVAC replacement take?
A standard rooftop unit replacement for a 5-25 ton unit typically takes one day. Larger equipment (30+ tons) or systems requiring crane lifts may take two days. We provide a specific timeline during the site assessment.
What is the cost of commercial HVAC replacement in Las Vegas?
Commercial HVAC replacement costs depend on tonnage, system type, equipment tier, and site conditions. A 5-ton rooftop unit replacement typically ranges from $8,000-$18,000 installed. Larger or more complex systems (15-30+ tons, VRF) range from $20,000-$60,000+. We provide detailed written estimates before any work begins.
Do I need a permit for commercial HVAC replacement?
Yes. Clark County requires a mechanical permit for commercial HVAC replacement. The Cooling Company pulls the permit, schedules the inspection, and handles the inspection sign-off as part of the installation scope. Never work with a contractor who suggests skipping permits on a commercial job; it creates liability exposure for the property owner.
Can I replace just the outdoor unit on my commercial system?
Partial replacement (outdoor unit only) is sometimes possible when the indoor air handler is relatively new and matched in refrigerant type. However, mixed-age systems often underperform because modern condensing units are designed to work as a system. We assess both components during the site visit and advise whether a matched-system replacement provides better value.
What refrigerant do new commercial HVAC systems use?
Most new commercial HVAC equipment uses R-410A refrigerant. Newer equipment released in 2025 and 2026 is transitioning to lower-GWP refrigerants (R-454B, R-32). R-22 systems cannot be recharged with modern refrigerants; they require full system replacement. We can advise on refrigerant compatibility during the assessment.
What happens to my old commercial HVAC unit?
We remove and dispose of the old unit as part of the replacement scope. Refrigerant is recovered by an EPA-certified technician before disposal. We handle disposal logistics including coordination for rooftop crane access when required for larger units.
