Carrier vs. Lennox vs. Trane: Which Is Best for Las Vegas? (2026 Comparison)

Why This Comparison Matters for Las Vegas Homeowners

Carrier, Lennox, and Trane are the three brands that appear on the shortlist of almost every serious HVAC buyer. They are the oldest names in residential air conditioning, they all manufacture premium variable-speed systems, and they all have active dealer networks in the Las Vegas Valley. When homeowners come to us asking which of the three to choose, the honest answer is that all three are capable of delivering excellent performance and 15-20 years of service in our climate.

That said, each brand has real differences in efficiency ceiling, compressor technology, coil design, warranty structure, dealer support, and pricing. Those differences matter more in Las Vegas than in most markets. When your system runs 2,500-3,500 hours per year in temperatures exceeding 115 degrees Fahrenheit, a 2-SEER2 efficiency difference produces hundreds of dollars in annual savings. A coil that corrodes three years earlier costs you a $1,500 repair you would not have needed with a better design. A warranty claim denied for a technicality on a $2,500 compressor is a gut punch that better fine-print reading could have prevented.

This comparison is built around Las Vegas-specific performance data, real installed pricing, actual warranty terms, and our field experience with all three brands across thousands of installations in the Las Vegas Valley. We are a Lennox Premier Dealer, which means we have the deepest expertise with Lennox. But we also install and service Carrier and Trane systems, and we will give you the same honest assessment we give every homeowner who walks through our door.

Flagship Models: The Best Each Brand Has to Offer

The fairest way to compare three premium brands is to start with their top products, then work down through the lineup to understand the full range of options and value propositions.

Lennox SL28XCV — The Dave Lennox Signature Collection Flagship

The Lennox SL28XCV is the most efficient residential central air conditioning system sold in the United States in 2026, rated at 28.0 SEER2. It uses a variable-speed inverter compressor that modulates between approximately 35% and 100% capacity in small increments, maintaining whatever output is needed to hold the thermostat setpoint rather than cycling on and off. The result is stable temperatures, excellent dehumidification, and electricity bills roughly 50-55% lower than a system operating at the federally mandated minimum efficiency of 14.3 SEER2.

The SL28XCV uses Lennox's proprietary Quantum Coil — an aluminum spine fin design with no copper tubing, which eliminates the formicary (formic acid) corrosion that affects standard copper-tube coils in environments with off-gassing from adhesives, cleaning products, and other household chemicals. In desert homes that tend to be tightly sealed during summer, this matters more than most buyers realize. The unit operates at 56 dB at maximum output, the quietest in its class, and 52 dB at partial load. That is roughly the sound level of a quiet conversation at six feet.

The SL28XCV requires pairing with a compatible Lennox air handler or coil and the iComfort S30 or E30 thermostat to achieve its rated efficiency. Installed in Las Vegas, a properly sized SL28XCV system with matched air handler runs $12,500–$17,000+ for a 3-ton application, depending on the contractor and any required ductwork modifications.

Carrier Infinity 26 (24VNA6) — The Infinity Series Flagship

The Carrier 24VNA6, sold under the Infinity 26 name, achieves 24 SEER2 with a variable-speed compressor that operates on Carrier's proprietary Greenspeed Intelligence control technology. The system modulates in very small steps — Carrier claims up to 700 incremental operating positions — which delivers the kind of steady temperature and humidity control that traditional two-stage systems cannot match.

The Infinity 26 uses Carrier's WeatherArmor Ultra cabinet, which is designed for corrosion resistance in coastal and hot/humid environments, and has performed well in Las Vegas's combination of UV exposure, dust, and occasional monsoon moisture. The unit uses a high-efficiency scroll compressor and requires pairing with an Infinity-compatible air handler and the Infinity Touch thermostat to achieve rated efficiency. At its operating range, the 24VNA6 produces 58-72 dB depending on load level — slightly louder than the Lennox SL28XCV but still well within comfortable outdoor noise levels.

Installed in Las Vegas, a properly matched Infinity 26 system runs $11,500–$16,000+ for a 3-ton application. Carrier's larger dealer network in Las Vegas often produces more competitive pricing than the Lennox equivalent.

Trane XV20i — The TruComfort Variable-Speed Flagship

The Trane XV20i reaches 21.5 SEER2 — lower than the Lennox and Carrier flagships — but delivers it through a TruComfort variable-speed inverter-driven compressor that Trane engineers for extreme durability. The XV20i features Trane's Spine Fin coil, a corrugated aluminum design that Trane claims maintains structural integrity and heat transfer efficiency better than traditional round-tube plate-fin coil designs under long-term thermal cycling. In desert conditions where condenser coils expand and contract with extreme daily temperature swings, the Spine Fin design's resistance to fin-tube separation is a meaningful durability advantage.

The XV20i requires the Nexia or Trane ComfortLink II thermostat for full variable-speed operation and integrates with Trane's smart home ecosystem. It produces 72-76 dB at full load, which is the loudest of the three flagships — a real consideration for units installed near windows, patios, or neighbor property lines. Installed in Las Vegas, the XV20i runs $11,500–$15,500+ for a 3-ton application with a matched Trane air handler.

Head-to-Head Comparison: 10 Categories

1. SEER2 Efficiency Range

Brand	Minimum (Base Model)	Mid-Range	Flagship
Lennox	14.3 SEER2 (Merit ML14XC1)	18.0 SEER2 (Elite XC18)	28.0 SEER2 (SL28XCV)
Carrier	14.3 SEER2 (Comfort 24ACC4)	17.0 SEER2 (Performance 24ACC7)	24.0 SEER2 (Infinity 26)
Trane	14.3 SEER2 (XR14c)	17.0 SEER2 (XR17)	21.5 SEER2 (XV20i)

Lennox's efficiency ceiling is substantially higher than either Carrier or Trane. The SL28XCV's 28.0 SEER2 versus Carrier's 24.0 and Trane's 21.5 is not a marginal difference. For a 3,000-square-foot Las Vegas home running 3,000 cooling hours per year, that gap translates to roughly $350-$550 in annual savings compared to the Carrier flagship and $550-$900 compared to the Trane flagship. At current Las Vegas NV Energy electricity rates (approximately 11-13 cents per kWh), the Lennox flagship pays back its premium over the Carrier Infinity in 4-6 years on electricity savings alone.

At the base model tier, all three brands are required to meet the federal Southwest minimum of 14.3 SEER2 and deliver similar real-world performance. The base-tier differences are less about efficiency and more about build quality and warranty structure.

2. Compressor Technology

Brand	Base Model	Mid-Range	Flagship
Lennox	Single-stage scroll	Two-stage scroll	Variable-speed inverter scroll
Carrier	Single-stage scroll	Two-stage Copeland scroll	Variable-speed Greenspeed inverter scroll
Trane	Single-stage scroll	Two-stage scroll	Variable-speed TruComfort inverter scroll

All three brands use scroll compressors from their base through flagship tiers, which is appropriate and expected at this quality level. Reciprocating compressors have no place in a premium system. The meaningful differentiation is at the flagship tier: Lennox's inverter uses a very broad modulation range (35-100%), Carrier's Greenspeed claims up to 700 discrete operating positions, and Trane's TruComfort modulates across its rated range with a focus on long-term durability over absolute efficiency ceiling.

In our field experience, Trane compressors show the lowest failure rate at the 10-15 year mark, followed closely by Carrier's Copeland-sourced compressors, with Lennox variable-speed compressors close behind. The difference at the compressor level is small among all three premium brands. The larger reliability differentiator tends to be control board quality and capacitor specifications — and there Lennox has improved substantially since the early iComfort generation issues of the early 2010s.

3. Warranty Comparison

Coverage	Lennox	Carrier	Trane
Compressor (base model)	10 years (registered)	10 years (registered)	10 years (registered)
Compressor (flagship)	10 years (registered)	10 years (registered)	Lifetime (XV20i, registered)
Parts (all models)	10 years (registered)	10 years (registered)	10 years (registered)
Labor (Premier/Factory Auth.)	5 years (Premier Dealer)	1 year standard / extended available	1 year standard / extended available
Registration deadline	60 days	90 days	60 days
Unregistered warranty	5 years parts	5 years parts	5 years parts

Trane's lifetime compressor warranty on the XV20i is the strongest single-item warranty in this comparison — a compressor that costs $2,000-$3,500 to replace is covered forever as long as you registered within 60 days of installation. That is a genuinely compelling warranty term for a homeowner planning to stay in their home long-term. Lennox's advantage is the 5-year labor warranty available through Premier Dealers, which reduces out-of-pocket repair costs during the first five years of ownership far beyond what Carrier or Trane's standard 1-year labor terms provide. Carrier's 90-day registration window is the most forgiving, which matters because a surprising number of homeowners miss registration deadlines during the chaos of a new installation.

In all three cases, professional installation by an authorized dealer is required to activate the full warranty. A system installed by an unlicensed contractor — or a system installed by a licensed contractor who fails to register it — drops to a 5-year parts-only warranty with no labor coverage. This is one of the most common warranty traps we see when homeowners call us to service a system installed by a non-authorized contractor.

4. Desert Performance and High-Ambient Operation

Standard SEER2 and capacity ratings are tested at 95 degrees Fahrenheit outdoor temperature. In Las Vegas, outdoor temperatures routinely exceed 110-117 degrees during peak summer. All three brand flagships use variable-speed inverter compressors that handle high ambient conditions better than single-stage competitors, but there are real differences in how each system is engineered for extreme heat.

Lennox rates the SL28XCV for continuous operation at outdoor temperatures up to 125 degrees Fahrenheit, with an estimated capacity retention of approximately 85-90% at 115 degrees. The Quantum Coil aluminum design has a larger surface area than traditional copper-tube configurations, which helps maintain heat rejection efficiency at extreme ambient temperatures.

Carrier rates the Infinity 26 for operation up to 125 degrees and publishes high-ambient performance data showing approximately 83-88% capacity retention at 115 degrees. The WeatherArmor Ultra cabinet and corrosion-resistant fan blade design are specifically engineered for harsh outdoor environments.

Trane rates the XV20i for operation up to 115 degrees as its published high-ambient limit, which is lower than the Lennox and Carrier specifications. Above 115 degrees, the XV20i relies on its refrigerant system pressure protection rather than rated continuous operation data. For Las Vegas, where July and August routinely see multiple days above 115 degrees, this is a real difference. The XV20i performs excellently at 110-113 degrees, but its rated ceiling is tighter than the Lennox and Carrier equivalents.

5. Noise Levels

Model	Minimum Load (dB)	Maximum Load (dB)
Lennox SL28XCV	52	56
Lennox XC21	67	72
Carrier 24VNA6 (Infinity 26)	58	72
Carrier 24ACC6 (Performance 17)	70	76
Trane XV20i	72	76
Trane XR17	74	78

The Lennox SL28XCV is in a category of its own at 52-56 dB. That is genuinely whisper-quiet — noticeably quieter than a standard window air conditioner, and not much louder than a quiet refrigerator. The Carrier Infinity 26 is competitive at 58 dB minimum but rises to 72 dB at full load. The Trane XV20i's 72-76 dB range is the loudest of the three flagships and would be noticeable near a bedroom window or outdoor living space. For homeowners with outdoor patios, side-yard units, or bedrooms adjacent to the AC unit location, the noise difference between a Lennox SL28XCV and a Trane XV20i is clearly perceptible and may be a deciding factor.

6. Smart Home and Thermostat Integration

All three brands have proprietary smart thermostat ecosystems, and all three integrate with Google Home, Amazon Alexa, and Apple HomeKit at the platform level. The differences are in depth of integration, app quality, and what proprietary features each thermostat unlocks.

Lennox's iComfort S30 and E30 thermostats integrate with the SL28XCV's inverter system to provide granular modulation control, predictive pre-cooling, and real-time efficiency reporting. The iComfort system shows actual system performance data — compressor speed, airflow, temperature differential — that most homeowners find genuinely useful for understanding what their system is doing. The Lennox app has improved substantially since 2022 and is now competitive with the Carrier and Trane equivalents.

Carrier's Infinity Touch thermostat provides deep integration with the Infinity 26's Greenspeed control system and has historically had the strongest third-party integration options, including native IFTTT and robust API access for home automation enthusiasts. Carrier has also been more aggressive about software updates to the thermostat platform.

Trane's ComfortLink II and Nexia thermostats integrate with the XV20i and provide remote monitoring, scheduling, and humidity control. Trane's app interface is functional but less polished than either the Lennox or Carrier equivalents. Trane's Nexia platform has broader integration with other smart home devices including locks, sensors, and cameras, which may matter to homeowners building an integrated smart home system.

7. Price Ranges (Installed, Las Vegas, 2026)

System Tier	Lennox	Carrier	Trane
Base (14.3 SEER2, single-stage)	$5,800 - $8,500	$5,500 - $8,200	$5,800 - $8,500
Mid-Range (17-18 SEER2, two-stage)	$8,500 - $12,000	$8,000 - $11,500	$8,200 - $11,500
Premium (21-24 SEER2, variable-speed)	$11,000 - $14,500	$11,500 - $16,000+	$11,500 - $15,500+
Flagship (25+ SEER2)	$12,500 - $17,000+	N/A	N/A

These prices reflect complete installed system costs including the outdoor condenser, matched indoor air handler or coil, refrigerant lines, electrical connections, and standard installation labor in Las Vegas. They assume no major ductwork modifications. Ductwork repairs, system upgrades (electrical panel work, new disconnect, etc.) or access challenges can add $500-$3,000 to any of these ranges.

One pricing reality that does not show up in these ranges: installation quality is as important as the equipment itself. A proper Manual J load calculation, correct refrigerant charge, and ductwork that actually delivers the right airflow to each room will determine whether a premium system performs at its rated efficiency — or falls well short of it. When comparing quotes, ask every contractor whether they perform a full load calculation and verify refrigerant charge with gauges. The contractor who does this work correctly is worth paying a premium for, regardless of which brand they install.

Carrier's slightly lower pricing at the base and mid tiers reflects the competitive pressure of a larger dealer network in the Las Vegas market. More Carrier dealers bidding for the same jobs pushes prices down. Lennox's premium at the top tier reflects the genuine performance advantage of the SL28XCV's 28.0 SEER2 ceiling over Carrier's 24.0 SEER2 maximum.

8. Parts Availability in Las Vegas

When your system needs a replacement capacitor, contactor, control board, or refrigerant charge on a 110-degree July afternoon, parts availability is not an abstract concern. All three brands have authorized parts distributors in Las Vegas, but the depth and speed of access varies.

Carrier has the largest parts distribution network in Las Vegas. Multiple local distributors stock a wide range of Carrier OEM parts, and the brand's large installed base means that common parts (capacitors, contactors, fan motors, control boards) are usually available same-day. For emergency repairs in peak season, Carrier's parts availability advantage is real.

Lennox parts distribution in Las Vegas has improved significantly over the past five years. As a Lennox Premier Dealer, we maintain an on-truck and warehouse inventory of the most common Lennox parts for our installed base. Specialty parts for older Lennox units can occasionally require 1-2 day shipping, which is a meaningful difference during a peak-heat breakdown.

Trane parts availability in Las Vegas is good for current production models but can be slower for older systems. Trane has fewer authorized distributors in the Las Vegas area than Carrier, and some specialty parts for the XV20i's TruComfort system require ordering from regional distribution centers.

9. Dealer Network and Service Quality

Carrier has the most authorized dealers in the Las Vegas Valley — more competition, which generally means more pricing options and faster response times during peak demand. The downside of a large dealer network is that quality is uneven. There are excellent Carrier dealers and mediocre ones, and without knowing specifically which contractor is doing the work, brand selection alone does not guarantee service quality.

Lennox's dealer structure uses a tiered certification system. Premier Dealers, like The Cooling Company, receive factory training, priority parts access, and are authorized to issue extended labor warranties. The Premier Dealer tier creates a stronger quality floor than Carrier's open authorized-dealer system. There are fewer Lennox Premier Dealers in Las Vegas than total Carrier authorized dealers, but the Premier Dealers tend to be more technically capable.

Trane uses a Comfort Specialist designation for its premium dealers, with requirements similar to Lennox's Premier Dealer program. Trane Comfort Specialists in Las Vegas are a smaller group but generally well-trained. Trane's factory technical support for complex diagnostic issues — particularly on the TruComfort inverter system — is frequently cited by contractors as the strongest of the three brands.

10. Coil Technology and Corrosion Resistance

Las Vegas's combination of alkaline hard water, year-round UV exposure, dust storms, and occasional monsoon humidity creates a challenging environment for condenser coils and evaporator coils. All three brands have invested in coil technology, but with different approaches.

Lennox's Quantum Coil uses an all-aluminum, spine-fin design with no copper tubing. The absence of copper eliminates formicary corrosion entirely and performs better than copper-tube coils in environments with household chemical off-gassing. The aluminum-only design also avoids galvanic corrosion from dissimilar-metal contact. For long-term desert operation, the Quantum Coil is the strongest standard coil design among the three brands.

Carrier uses a coated copper-tube aluminum fin coil with its WeatherArmor treatment on premium models. The coating provides meaningful protection against standard corrosion, and the WeatherArmor Ultra treatment on the Infinity series adds additional UV and salt protection. The coil performs very well in Las Vegas conditions and has a strong track record over 15-year system lifespans.

Trane's Spine Fin coil uses a corrugated aluminum fin design with copper tubes, similar in principle to other premium coils. The Spine Fin's structural advantage — increased rigidity that resists thermal expansion stress — reduces the tube-to-fin joint failures that occasionally appear in standard coils after years of Las Vegas thermal cycling. The coil performs well, though it does not match the all-aluminum Lennox Quantum Coil design for complete corrosion elimination.

Full Lineup Comparison: Merit Through Signature

Lennox Complete Lineup

Lennox organizes its residential AC products into three tiers. The Merit Series (ML14XC1, ML14XC2) covers the base efficiency tier at 14.3-14.5 SEER2 with single-stage compressors, standard coils, and 10-year parts warranties when registered. These are solid, straightforward systems for homeowners on tighter budgets who still want the Lennox brand. The Elite Series (XC18, XC21) bridges the gap with two-stage compressors achieving 18.0-21.0 SEER2, variable-speed blower motors, and improved sound packages. The Dave Lennox Signature Collection (XC25, SL28XCV) represents the pinnacle — variable-speed inverter compressors, Quantum Coil, iComfort integration, and efficiency ratings that no other brand matches.

Carrier Complete Lineup

Carrier uses a Comfort/Performance/Infinity naming structure. Comfort Series (24ACC4, 24ACC6) covers the 14.3-16.0 SEER2 base tier with single-stage compressors and standard warranties. The Performance Series (24ACC7, 24VNA0) covers 17.0-19.0 SEER2 with two-stage compressors and improved coil coating. The Infinity Series (24VNA6 flagship, plus the 19-21 SEER2 Infinity 20 and Infinity 21 models) uses variable-speed Greenspeed technology with WeatherArmor Ultra protection. Carrier also offers the Bryant brand, which uses Carrier's same manufacturing lines with slightly different model naming and pricing.

Trane Complete Lineup

Trane's lineup runs from XR-series base models (XR14c, XR15c at 14.3-15.0 SEER2 with single-stage compressors) through the XR17 (17.0 SEER2, two-stage) and XL18i (17.2 SEER2, two-stage with variable-speed air handler) to the premium XV18 (18.0 SEER2, variable-speed) and flagship XV20i (21.5 SEER2, TruComfort variable-speed). American Standard, owned by the same parent company (Trane Technologies), uses identical manufacturing with different branding. For comparison, Trane's HVAC business is profiled by Trane Residential directly.

Which Brand Is Right for Which Las Vegas Homeowner

Choose Lennox if:

• Electricity efficiency is your top priority and you plan to stay in your home 10+ years
• You want the quietest possible outdoor unit, especially near patios or bedrooms
• You want extended labor warranty coverage (5 years through a Premier Dealer)
• Your home has an existing Lennox system and you want a matched replacement
• You want the most advanced iComfort smart thermostat integration with real-time performance data
• You are in a newer, well-sealed Las Vegas home where the all-aluminum Quantum Coil's corrosion resistance provides maximum long-term value

Choose Carrier if:

• You want the largest dealer network for pricing competition and parts availability
• You are comfortable with 24.0 SEER2 as your efficiency ceiling (not needing the Lennox 28.0 premium)
• You value the Carrier brand's depth of third-party smart home integrations
• You have an existing Carrier system and want continuity with compatible controls and refrigerant infrastructure
• Emergency repair speed matters most — Carrier's parts distribution in Las Vegas is the fastest of the three

Choose Trane if:

• Compressor longevity and the lifetime compressor warranty on the XV20i are your primary concern
• You are in an older Las Vegas home with established Trane system history
• You want the Spine Fin coil's structural durability advantage for a home with severe thermal cycling exposure
• Budget sensitivity leads you toward the XV20i tier where Trane is price-competitive with Carrier Infinity, but you want slightly different brand exposure
• Your home automation uses Nexia as its platform

Total Cost of Ownership: 10-Year Comparison

Choosing an air conditioner on installed price alone is one of the most common and expensive mistakes Las Vegas homeowners make. The system that costs $1,500 more to install can easily pay back that premium — and then some — through electricity savings over a 10-year operating period.

Consider a typical Las Vegas scenario: 2,000 square feet, 3-ton system requirement, 3,000 cooling hours per year, NV Energy rate of 12 cents per kWh. Comparing the Lennox SL28XCV (28.0 SEER2) against the Trane XV20i (21.5 SEER2) and a base-tier single-stage system (14.3 SEER2):

System	Annual kWh (3 ton, 3,000 hrs)	Annual Cost at $0.12/kWh	10-Year Energy Cost	Installed Cost (est.)	10-Year Total
Base 14.3 SEER2	~7,600 kWh	~$912	~$9,120	$7,000	~$16,120
Trane XV20i (21.5 SEER2)	~5,050 kWh	~$606	~$6,060	$13,000	~$19,060
Carrier Infinity 26 (24 SEER2)	~4,525 kWh	~$543	~$5,430	$13,500	~$18,930
Lennox SL28XCV (28 SEER2)	~3,875 kWh	~$465	~$4,650	$14,500	~$19,150

Note that at a 10-year horizon, the base system's lower installed cost is nearly entirely consumed by its higher energy bills. The three premium systems all land within $300 of each other at 10 years total cost — the key variable becomes maintenance costs, repair frequency, and expected system lifespan beyond year 10. A premium variable-speed system has a strong probability of reaching 18-22 years in Las Vegas. A base single-stage system, with its hard-cycling stress in extreme heat, is more likely to need replacement at 12-15 years.

Federal tax credits add another dimension: qualifying heat pumps earn up to $2,000 in 25C credits, and qualifying high-efficiency AC systems can earn up to $600. See our complete guide to replacing your AC in 2026 for full details on available incentives.

The Verdict: Our Honest Recommendation

We are a Lennox Premier Dealer, and we are going to be honest with you: the best system for your home is not automatically a Lennox. All three of these brands build excellent products. The SL28XCV is the most efficient residential AC available, and we install it confidently knowing it will perform for 18-22 years in Las Vegas when properly maintained. But the Carrier Infinity 26 is a legitimately excellent system at a similar price with better parts availability, and the Trane XV20i's lifetime compressor warranty is a genuinely compelling offer for homeowners who plan to stay in their home for decades.

Our recommendation framework is simple. If efficiency and quiet operation are your top priorities, choose Lennox — specifically the SL28XCV if budget allows, or the XC21 if you want to spend $2,000 less and accept slightly lower peak efficiency. If you want the largest dealer network, fastest parts access, and a premium variable-speed system at slightly lower cost than the Lennox flagship, choose the Carrier Infinity 26. If long-term compressor durability and the lifetime warranty matter most to you, and you can accept a lower efficiency ceiling and slightly louder operation, choose the Trane XV20i.

What matters most is getting the right size system calculated with a proper Manual J load calculation at 115 degrees Fahrenheit design temperature, having it installed correctly by a trained technician, and maintaining it properly with monthly filter changes and annual professional service. A perfectly installed base system from any of these three brands will outperform a poorly installed flagship every time.

Frequently Asked Questions

Is Lennox really better than Carrier and Trane, or is that just because you sell it?

We are a Lennox Premier Dealer, and we acknowledge that creates a potential bias. Here is our honest answer: Lennox is objectively superior in efficiency (28.0 SEER2 vs. 24.0 and 21.5) and noise level (52-56 dB vs. 58-76 dB). Carrier has a meaningfully better parts availability network in Las Vegas and a larger pool of authorized dealers. Trane offers the only lifetime compressor warranty in this group and has a compelling track record for compressor longevity. If you asked us to install any of these three systems in our own homes, we would install the Lennox SL28XCV — but only because our team has the deepest expertise with it, not because it is categorically better than a Carrier Infinity 26 or Trane XV20i installed and maintained properly.

What is the real difference between Carrier and Bryant?

Bryant is a Carrier subsidiary manufactured on the same assembly lines with essentially identical components. Bryant uses different model numbers and a slightly different dealer network (often targeting value-oriented buyers), but the products are functionally the same. A Bryant Evolution system is mechanically identical to the corresponding Carrier Infinity system. The main difference is branding and sometimes pricing. If a Bryant dealer quotes you a lower price than a Carrier dealer for what appears to be an equivalent system, they are likely comparing the same mechanical product with different badge engineering.

How do these brands compare on R-454B refrigerant transition?

All three brands are actively transitioning their product lines from R-410A refrigerant to R-454B (also branded as Puron Advance by Carrier) in compliance with the EPA's AIM Act requirements. New equipment manufactured in 2025 and 2026 increasingly uses R-454B, which has roughly 75% lower global warming potential than R-410A. Carrier was the first to brand its R-454B refrigerant as a product differentiator. Lennox and Trane are on similar transition timelines. For buyers purchasing in 2026, confirm with your contractor whether the system being quoted uses R-410A or R-454B, as this affects long-term refrigerant supply and cost-of-ownership.

Which brand holds up best in Las Vegas's specific desert conditions?

All three brands' premium products perform well in Las Vegas, but with these specific notes: Lennox's Quantum Coil design offers the best protection against formicary and galvanic coil corrosion in tightly sealed desert homes. Carrier's WeatherArmor treatment and proven track record in hot/arid climates makes it an excellent choice for desert longevity. Trane's XV20i operates at a lower published high-ambient limit (115 degrees F) than the Lennox SL28XCV and Carrier Infinity 26 (both rated to 125 degrees F), which is a real consideration in Las Vegas where peak temperatures regularly reach 115-118 degrees during the hottest weeks of July and August.

Can I get a Carrier or Trane system serviced by The Cooling Company?

Yes. We are a Lennox Premier Dealer, which is our deepest area of expertise, but our licensed technicians are trained and equipped to service, repair, and maintain Carrier and Trane systems as well. We carry common Carrier and Trane parts in our service vehicles. For warranty work on Carrier or Trane systems, you will want to confirm with us whether the specific repair falls under a warranty claim that requires authorization through a Carrier or Trane authorized dealer. Call (702) 567-0707 and we will walk you through your options.

How much will I actually save on electricity with a premium variable-speed system?

For a typical Las Vegas 2,000-square-foot home, upgrading from a 14.3 SEER2 single-stage system to a Lennox SL28XCV (28.0 SEER2) saves approximately $400-$900 per year on cooling costs at current NV Energy rates. The wide range reflects differences in home insulation, thermostat setpoints, occupancy patterns, and cooling load. NV Energy occasionally offers rebates for high-efficiency system installations — see NV Energy's heating and cooling rebate programs for current offers. Combined with federal tax credits, the out-of-pocket cost premium for a variable-speed system over a base single-stage model can be reduced by $1,500-$3,500, improving the payback period substantially.

Which brand is most commonly installed in new Las Vegas construction?

New Las Vegas construction is dominated by Carrier, Lennox, and Trane at the production builder level, with Carrier holding the largest share among the major Las Vegas builders (Pulte, DR Horton, Lennar, Toll Brothers). Builder-grade systems tend to be base or mid-range efficiency models — 14.3-16.0 SEER2 single-stage or two-stage units — chosen primarily on initial cost rather than long-term efficiency. If your new construction home came with a builder-grade system, you are a candidate for an efficiency upgrade when that system reaches end of life. Our AC replacement service includes a free assessment and we can match or improve on whatever efficiency the builder installed.
