Short answer: Replacing your AC and furnace together in Las Vegas typically costs $9,500-$14,500 — saving $1,000-$2,500 compared to replacing them separately ($10,325-$17,275 total). The bundle saves money through reduced labor, one permit instead of two, shared ductwork assessment, and matched-system efficiency gains of 5-15%. It makes the most sense when both systems are 10+ years old or when you are converting to a heat pump. But if your furnace is under 5 years old and working well, replacing only the AC is the smarter move. NV Energy PowerShift rebates of $300-$2,000 can reduce the net cost further.

Key Takeaways
- Bundling saves $1,000-$2,500 over separate replacements because one crew handles both units in a single visit — eliminating duplicate labor, a second permit fee, and redundant ductwork inspection. The savings increase with system complexity.
- Matched systems are 5-15% more efficient than mismatched ones. An AHRI-certified matched pair (same manufacturer, tested together) delivers its rated SEER and AFUE because the components are engineered to communicate and optimize together. Mismatched systems lose efficiency at the handoff points.
- The best time to bundle is when both systems are 10+ years old, or when one fails and the other is past its midlife. Replacing a 12-year-old furnace now — while the crew is already on-site — costs far less than calling for a separate emergency furnace install two winters later.
- Do NOT bundle if your furnace is under 5 years old and working well. You would be throwing away 10-15 years of remaining furnace life. Replace the AC alone and revisit the furnace when it actually needs replacement.
- NV Energy PowerShift rebates ($300-$2,000) are your primary financial incentive for 2026. The federal Section 25C tax credit was terminated for 2026 installations under the One Big Beautiful Bill Act. NV Energy rebates apply to qualifying high-efficiency equipment and can be stacked across both units when you bundle.
- The heat pump alternative eliminates the furnace entirely. A single heat pump system replaces both your AC and furnace for $7,500-$12,650 (3-ton), which is less than the combined cost of separate AC + furnace replacement. For most Las Vegas homes, a heat pump handles 95%+ of heating needs.
Why This Decision Matters More in Las Vegas
In milder climates, the furnace question is almost an afterthought. The AC does 90% of the annual work, and the furnace sits idle for 10 months. In Las Vegas, the math is different — and understanding it saves you thousands.
Your air conditioner runs 2,400-3,000 hours per year here, far more than the national average of 1,000-1,200 hours. That extreme runtime means AC efficiency matters enormously — every SEER point translates to real dollars on your NV Energy bill. But Las Vegas also gets 40-60 winter nights below 40 degrees, and December through February nights regularly dip into the 30s. Your furnace is not decorative. It runs 600-900 hours per year, and an aging, inefficient furnace paired with a new high-efficiency AC creates a system that underperforms in both seasons.
The question is not whether you need both systems. You do. The question is whether replacing them together — right now — makes more financial sense than doing them one at a time. For many Las Vegas homeowners, the answer is yes. But not for everyone, and not in every situation.
This article gives you the actual numbers, the scenarios where bundling wins, the scenarios where it does not, and a clear decision framework so you can make the right call for your home and your budget.
The Complete Cost Comparison: Separate vs. Bundled
Here is where most of the confusion lives, so let me lay out the numbers side by side. These are real Las Vegas installed prices for a typical 3-ton system in a standard single-story home with existing ductwork. Prices include equipment, labor, materials, permits, and a standard thermostat.
Replacing Each System Separately
| Component | Price Range (Installed) | What's Included |
|---|---|---|
| AC only (3-ton, 14-20 SEER2) | $6,325 - $9,775 | Condenser, evaporator coil, refrigerant lines, labor, permit |
| Furnace only (80,000 BTU) | $4,000 - $6,500 | Furnace unit, venting, gas line connection, labor, permit |
| Total if done separately | $10,325 - $16,275 | Two separate crews, two permits, two ductwork assessments |
Replacing Both Together (Bundled)
| Component | Price Range (Installed) | What's Included |
|---|---|---|
| AC + Furnace bundle (3-ton, 80k BTU) | $9,500 - $14,500 | Matched condenser + furnace, coil, lines, venting, one permit, one crew |
| Bundle savings | $825 - $1,775 | Reduced labor, single permit, shared ductwork assessment |
The savings come from several places. A single crew doing both installations in one visit eliminates 4-6 hours of redundant labor (accessing the same mechanical closet, the same attic, the same ductwork twice). One permit instead of two saves $150-$350 in Clark County. The ductwork assessment, which must happen with any equipment change, only needs to be done once. And HVAC distributors typically offer package pricing when a contractor orders the matched indoor and outdoor units together.
On higher-end installations — variable-speed systems, homes requiring ductwork modifications, or multi-zone setups — the savings from bundling are even more pronounced, often reaching $2,000-$2,500. The more complex the job, the more you save by doing it once.
Pricing for Larger Systems
The numbers above reflect a 3-ton system, which covers most Las Vegas homes between 1,200 and 1,800 square feet. Larger homes need larger systems, and the costs scale accordingly.
| System Size | Typical Home Size | AC Alone | Furnace Alone | Bundled | Bundle Savings |
|---|---|---|---|---|---|
| 2-ton | 800-1,200 sq ft | $5,200 - $7,800 | $3,500 - $5,500 | $7,800 - $11,500 | $900 - $1,800 |
| 3-ton | 1,200-1,800 sq ft | $6,325 - $9,775 | $4,000 - $6,500 | $9,500 - $14,500 | $825 - $1,775 |
| 4-ton | 1,800-2,400 sq ft | $7,500 - $11,500 | $4,500 - $7,500 | $10,800 - $16,800 | $1,200 - $2,200 |
| 5-ton | 2,400-3,200 sq ft | $9,000 - $14,000 | $5,200 - $8,500 | $12,500 - $20,000 | $1,700 - $2,500 |

When Replacing Both Together Makes Clear Financial Sense
Not every homeowner should bundle. But in these five scenarios, the math strongly favors replacing AC and furnace at the same time.
Scenario 1: Both Systems Are 10+ Years Old
This is the clearest case. A central AC in Las Vegas lasts 12-18 years, and a gas furnace lasts 15-25 years. If both systems were installed at the same time (common in new construction) and are now past the 10-year mark, you are approaching the window where failures become likely and repair costs escalate.
Replacing a 12-year-old AC now while leaving a 12-year-old furnace in place means you will likely need to replace that furnace within 3-8 years — paying for a second installation crew, a second permit, and a second round of ductwork disruption. The $1,000-$2,500 you save by bundling today is money you would otherwise spend on redundant labor later.
Scenario 2: Your AC Failed and Your Furnace Is Past Its Midlife
This is the most common scenario we see. The AC dies in June (as they do), and the homeowner calls for emergency AC repair only to learn the compressor is shot and the system needs full replacement. The furnace, meanwhile, is 8-12 years old and still running — but it has already consumed more than half its useful life.
Replacing the furnace now, while the crew is already in your mechanical closet and the ductwork is already exposed, adds $3,000-$5,000 to the project. Waiting and doing it separately in a few years costs $4,000-$6,500 — plus you miss out on matched-system efficiency gains for the intervening years.
Scenario 3: You Are Converting to a Heat Pump System
If you are considering a heat pump instead of a traditional AC + furnace setup, you are inherently replacing both systems. A heat pump provides both cooling and heating in one unit, eliminating the furnace entirely. This is a natural bundle — and the economics are compelling for Las Vegas homes. More on this in the heat pump section below.
Scenario 4: Your Current Systems Are Mismatched
If a previous homeowner or contractor replaced the AC but not the furnace (or vice versa), your indoor and outdoor units are almost certainly not an AHRI-matched pair. Mismatched systems lose 5-15% of their rated efficiency because the components were never tested or engineered to work together. The refrigerant metering, airflow rates, and communication protocols may all be suboptimal.
Replacing both with a matched set from the same manufacturer restores the rated efficiency and often improves comfort (more consistent temperatures, better humidity control, quieter operation).
Scenario 5: You Want to Maximize NV Energy Rebates
NV Energy's PowerShift program offers rebates on qualifying high-efficiency equipment. When you replace both units at once, you can stack rebates — claiming the AC rebate and the furnace rebate on the same project. The combined rebate can reach $1,500-$3,000 depending on the efficiency tier of the equipment you choose. Doing them separately in different years still qualifies for individual rebates, but you miss out on contractor package pricing and bundled labor savings.
When You Should NOT Replace Both Together
Bundling is not always the right call. In these situations, replacing only one system is the smarter financial decision.
Your Furnace Is Less Than 5 Years Old
A furnace that is 2-5 years old has 15-20 years of useful life remaining. Replacing it now means throwing away $3,000-$5,000 worth of remaining equipment value. Even with the $1,000-$2,500 bundle savings, you are still net negative. Replace the AC alone and wait for the furnace to reach its natural end of life.
Only the AC Failed and Your Furnace Has Remaining Warranty
If your furnace still has manufacturer warranty coverage — especially on the heat exchanger, which typically carries a 20-year or lifetime warranty — replacing it early means forfeiting that coverage on the old unit. The warranty has real financial value. Replace the AC, keep the warranted furnace, and revisit when the warranty expires or the unit fails.
Budget Constraints Are Real
If your budget genuinely cannot absorb a $9,500-$14,500 project, replacing just the AC ($6,325-$9,775) addresses the immediate need at a lower out-of-pocket cost. A properly sized and installed AC will function correctly with an older furnace — you just will not get the matched-system efficiency bonus. That is an acceptable trade-off when the alternative is financing more than you can comfortably repay.
That said, HVAC financing can make the bundle accessible for many homeowners who cannot pay cash. We will cover the monthly payment math later in this article.
Your Furnace Was Recently Serviced and Is in Good Condition
If a qualified technician has recently inspected your furnace and confirmed the heat exchanger, burners, and blower motor are in good condition, the furnace may have significant life remaining even if it is 10-12 years old. A well-maintained 80% AFUE furnace that is running safely does not need preemptive replacement just because the AC failed. Get a professional assessment — not a sales pitch — and make the call based on actual condition.
Why Matched Systems Matter: The Efficiency You Are Paying For
This is the part most contractors gloss over, but it is one of the biggest reasons to bundle. When you buy a 16 SEER2 air conditioner, that 16 SEER2 rating was tested with a specific indoor coil and a specific air handler or furnace. That tested combination is registered with AHRI (Air-Conditioning, Heating, and Refrigeration Institute) as a matched system. The efficiency rating only applies to that specific combination.
When you pair a new 16 SEER2 condenser with your old furnace blower, the system is unmatched. The blower may push too much or too little air across the new coil. The refrigerant metering device may not be optimized for the new unit's charge requirements. The result is a system that was rated at 16 SEER2 but actually performs at 13-15 SEER2 in your home.
Here is what that efficiency loss costs you annually in Las Vegas:
| Scenario | Effective SEER | Annual Cooling Cost (3-ton) | Annual Penalty |
|---|---|---|---|
| AHRI-matched 16 SEER2 system | 16 | $760 | — |
| New 16 SEER2 AC + old furnace blower (mismatched) | ~14 | $868 | $108/year |
| New 20 SEER2 AC + old furnace blower (mismatched) | ~16-17 | $715-$760 | $90-$135/year |
Over 15 years, that mismatch penalty adds up to $1,350-$2,025 in wasted energy — which erodes or eliminates the savings you thought you were getting by keeping the old furnace. For homes with high-efficiency systems (18+ SEER2), the mismatch penalty is even more severe because variable-speed and two-stage compressors are especially sensitive to airflow optimization.
The bottom line: if you are spending $7,000-$10,000 on a new AC, spending an additional $3,000-$5,000 to get the furnace matched ensures you actually receive the efficiency you paid for. Otherwise, you are buying a 16 SEER2 rating on paper and getting 14 SEER2 performance in practice.
Where the Labor Savings Come From
The sticker price of a bundle looks like "equipment cost + labor," but the labor savings from bundling are more substantial than most homeowners realize. Here is the breakdown.
| Labor Component | Separate Installs | Bundled Install | Savings |
|---|---|---|---|
| Site preparation (equipment staging, drop cloths, access) | Done twice | Done once | 1-2 hours |
| Ductwork inspection and testing | Done twice | Done once | 1-2 hours |
| Electrical assessment and disconnect | Done twice | Done once | 0.5-1 hour |
| Thermostat wiring and setup | Done twice (reconfigured) | Done once (clean install) | 0.5-1 hour |
| System commissioning and testing | Tested separately | Tested as integrated system | 1-2 hours |
| Permit fee | Two permits ($300-$700) | One permit ($150-$350) | $150-$350 |
| Truck roll and crew mobilization | Two visits | One visit | $200-$400 |
| Total labor savings | 4-8 hours + $350-$750 |
At Las Vegas HVAC labor rates of $85-$150 per hour per technician, those 4-8 redundant hours represent $340-$1,200 in labor cost alone. Add the permit and mobilization savings, and the total labor-side savings from bundling range from $690-$1,950.
There is also an intangible benefit: your home is disrupted once instead of twice. One day with technicians in your mechanical closet, one day without AC during the swap, one day of post-installation adjustment. If you have done a separate install, you know how disruptive it is. Doing it twice is twice as disruptive.
NV Energy Rebates: Stacking the Savings
NV Energy's PowerShift rebate program is the primary financial incentive for high-efficiency HVAC equipment in 2026. The federal Section 25C energy efficiency tax credit, which previously offered up to $2,000 for qualifying heat pumps and $600 for qualifying furnaces, was terminated for 2026 installations under the One Big Beautiful Bill Act. That makes NV Energy rebates your main tool for reducing net cost.
Here is what is currently available for bundled replacements:
| Equipment | Qualifying Efficiency | NV Energy Rebate |
|---|---|---|
| Central AC | 16+ SEER2 | $300 - $1,200 |
| Gas Furnace | 95%+ AFUE | $300 - $500 |
| Heat Pump (replaces both) | 16+ SEER2 / 9+ HSPF2 | $500 - $2,000 |
| Smart Thermostat | ENERGY STAR certified | $50 - $100 |
| Maximum combined (AC + Furnace + Thermostat) | $650 - $1,800 |
The advantage of bundling for rebate purposes is timing. NV Energy processes one application per project, and getting both rebates approved simultaneously is faster and simpler than filing separate applications months or years apart. Your contractor (that is us, if you call (702) 567-0707) handles the paperwork as part of the installation.
For the full breakdown on what federal incentives are and are not available in 2026, see our 2026 federal tax credit guide.
The Heat Pump Alternative: Replace Both With One System
There is a third option that an increasing number of Las Vegas homeowners are choosing: replace both the AC and furnace with a single heat pump system. A heat pump provides cooling (just like an AC) and heating (eliminating the furnace) in one unit.
Here is how the economics compare for a 3-ton system:
| Option | Installed Cost | Annual Energy Cost | NV Energy Rebate | Net Cost After Rebate |
|---|---|---|---|---|
| AC + Furnace bundle | $9,500 - $14,500 | $1,600 - $2,200 | $600 - $1,800 | $7,700 - $13,900 |
| Heat Pump (replaces both) | $7,500 - $12,650 | $1,400 - $1,900 | $500 - $2,000 | $5,500 - $12,150 |
A heat pump costs less upfront than the AC + furnace bundle, operates more efficiently for heating (because it moves heat rather than generating it from combustion), and qualifies for the highest NV Energy rebate tier. In Las Vegas, where winter temperatures rarely drop below 25 degrees, a modern heat pump handles heating loads efficiently down to outdoor temperatures where furnace backup would be needed only a handful of nights per year.
The trade-offs are real but manageable. A heat pump delivers slightly lower heating output at very cold temperatures (below 30 degrees), so some homeowners add a small electric resistance backup strip for the coldest nights. And if you have an existing natural gas line and gas is significantly cheaper than electricity in your area, the operating cost advantage of a heat pump narrows.
For most Las Vegas homes — especially those built after 2000 with decent insulation — a heat pump is the most cost-effective way to replace both systems at once. Read our full heat pump cost guide or our analysis on converting from gas furnace to electric heating for the complete breakdown.
Financing the Bundle: What the Monthly Payments Actually Look Like
A $9,500-$14,500 project is a significant expense. Most Las Vegas homeowners finance HVAC replacements, and financing options make the bundle accessible even when paying cash is not realistic.
Here are real monthly payment examples for a bundled AC + furnace replacement at different price points and credit tiers:
| Project Cost | Term | Good Credit (5.9-8.9% APR) | Fair Credit (12.9-16.9% APR) | Challenged Credit (18.9-24.9% APR) |
|---|---|---|---|---|
| $9,500 | 60 months | $183 - $196/mo | $216 - $237/mo | $248 - $275/mo |
| $9,500 | 120 months | $108 - $121/mo | $143 - $163/mo | $178 - $204/mo |
| $12,000 | 60 months | $231 - $248/mo | $273 - $299/mo | $313 - $348/mo |
| $12,000 | 120 months | $137 - $153/mo | $181 - $206/mo | $225 - $258/mo |
| $14,500 | 60 months | $280 - $300/mo | $330 - $362/mo | $379 - $420/mo |
| $14,500 | 120 months | $165 - $185/mo | $218 - $249/mo | $272 - $312/mo |
An important way to evaluate these payments: compare them to your current monthly energy waste. If your old, inefficient systems are costing you $100-$175 per month more in energy than new matched equipment would, that energy savings offsets a significant portion of the monthly payment. A $183/month payment on a 60-month loan at 5.9% APR, offset by $125/month in energy savings, has an effective net cost of $58/month. That is $58/month for a brand new, warrantied, efficient system — instead of $125/month in waste going to NV Energy for equipment that could fail any day.

3 Real Case Studies From Las Vegas Neighborhoods
These are composite examples based on real installations we have completed. Details are anonymized, but the numbers, neighborhoods, and outcomes are representative of actual projects.
Case Study 1: Summerlin — 2004 Build, Both Systems Original
Situation: A 2,100 square foot two-story home in Summerlin built in 2004 with the original builder-grade 10 SEER Goodman AC and 80% AFUE furnace. Both systems were 22 years old. The AC had needed two compressor capacitor replacements and a contactor replacement in the past three years. The furnace had a cracked inducer motor housing that was repaired but showing signs of heat exchanger wear.
Decision: Replace both with a matched Lennox 17 SEER2 AC and 96% AFUE variable-speed furnace.
Cost breakdown:
- Bundled installation: $12,800
- NV Energy PowerShift rebate (AC): $800
- NV Energy PowerShift rebate (furnace): $400
- Net cost: $11,600
- Estimated annual energy savings: $1,350 (from 10 SEER/80% AFUE to 17 SEER2/96% AFUE)
- Simple payback on net cost: 8.6 years
If they had replaced separately: AC alone would have cost $8,200. Furnace alone (likely needed within 2-3 years) would have cost $5,800. Total: $14,000 — $2,400 more than the bundle, plus 2-3 years of mismatched system inefficiency.
Case Study 2: Henderson — 2012 Build, AC Failed, Furnace Questionable
Situation: A 1,750 square foot single-story home in Henderson built in 2012 with a 14 SEER Rheem AC and 80% AFUE furnace. The AC compressor failed in August at 14 years old. The furnace was also 14 years old, still operational, but the blower motor was showing signs of wear (intermittent noise, occasional slow start).
Decision: After discussing the options, the homeowner chose to replace both with a matched 16 SEER2 Lennox system with a 95% AFUE furnace.
Cost breakdown:
- Bundled installation: $10,400
- NV Energy PowerShift rebate (combined): $900
- Net cost: $9,500
- Estimated annual energy savings: $680 (from 14 SEER/80% AFUE to 16 SEER2/95% AFUE)
- Avoided future furnace replacement cost: ~$5,200 (saved $1,400 vs. separate)
Why bundling won: The $1,400 in bundle savings plus the avoided risk of a furnace failure during a cold snap made the decision clear. They also avoided the inconvenience and cost of a second installation project in 2-5 years.
Case Study 3: North Las Vegas — 2018 Build, AC-Only Replacement
Situation: A 1,600 square foot home in North Las Vegas built in 2018 with a 14 SEER Carrier AC and 96% AFUE furnace. The AC developed a refrigerant leak at the evaporator coil at 8 years old — repairable, but the repair cost ($1,800-$2,400) was approaching the threshold where replacement made more sense.
Decision: Replace the AC only. Keep the 8-year-old furnace.
Cost breakdown:
- AC-only installation (matched Carrier 17 SEER2 condenser + new coil): $7,600
- NV Energy PowerShift rebate: $600
- Net cost: $7,000
Why AC-only was right: The furnace was only 8 years old, still under the 20-year heat exchanger warranty, and performing at full efficiency. Replacing it would have wasted $4,000-$5,000 in remaining equipment value. The homeowner chose a Carrier condenser that is AHRI-matched with the existing furnace — maintaining matched-system efficiency without unnecessary replacement.
This case illustrates an important point: bundling is not always the right answer. A good contractor will tell you when keeping your existing equipment is the smarter move.
Your Decision Framework: Bundle or Replace One?
Use this step-by-step framework to evaluate your specific situation. Answer each question honestly — the right decision depends on your home, not on what saves the contractor the most on labor.
Step 1: How old is each system?
- Both 10+ years old → Strong case for bundling
- One is 10+ years, the other is 5-9 years → Consider bundling (depends on condition)
- One is 10+ years, the other is under 5 years → Replace only the older one
Step 2: What is the condition of the system you are NOT replacing?
- Recent repair history, unusual noises, declining performance → Lean toward bundling
- Recently serviced, clean bill of health, no repair history → Lean toward single replacement
- Unknown condition (never serviced or inspected) → Get a professional assessment before deciding
Step 3: Are your current systems matched?
- Installed at the same time, same brand, same contractor → Probably matched. Replacing one breaks the match.
- Installed at different times or by different contractors → Already mismatched. Bundling restores matched efficiency.
Step 4: What is your budget situation?
- Can afford the full bundle ($9,500-$14,500) or finance it comfortably → Bundle if Steps 1-3 support it
- Budget is tight, can only afford one system → Replace the failed/failing system now, plan for the other
Step 5: Are you considering a heat pump conversion?
- Yes → This is inherently a bundle (the heat pump replaces both systems)
- No, staying with AC + furnace → Follow Steps 1-4
If you want an expert to walk through this framework with you for your specific home, call (702) 567-0707 or book a free assessment online. We will inspect both systems, give you honest condition assessments, and provide pricing for every option — replace AC only, replace furnace only, bundle both, or convert to heat pump. No pressure, just clarity.
What to Expect During a Bundled Installation
Understanding the timeline helps you plan around the disruption.
Day 1 (Assessment and Quote): A technician visits your home, inspects both systems, performs a Manual J load calculation to confirm correct sizing, inspects ductwork condition, and provides a written quote with all options. This visit takes 60-90 minutes and is free.
Day 2 (Installation): A crew of 2-3 technicians arrives in the morning. For a standard AC + furnace bundle in a single-story home with accessible equipment, the installation takes 6-10 hours. The old condenser, furnace, and evaporator coil are removed. The new equipment is installed, connected, and integrated. Refrigerant lines are brazed or replaced, the gas line is reconnected and leak-tested, and electrical connections are made.
Day 2 (Commissioning): After installation, the crew performs system commissioning: checking refrigerant charge, verifying airflow across the coil, testing all safety controls, calibrating the thermostat, and running the system through heating and cooling cycles to confirm proper operation.
Day 3 (Inspection): Clark County requires a mechanical permit and inspection for HVAC replacements. The inspection typically occurs 1-3 business days after installation and takes 15-30 minutes. You do not need to be home for the inspection in most cases.
For two-story homes, attic installations, or projects requiring ductwork modifications, the installation may extend to a full second day. Your contractor should communicate the expected timeline before work begins.
How to Choose the Right Contractor for a Bundled Job
A bundled AC + furnace replacement is more complex than a single-system swap. The contractor must be proficient with both cooling and heating systems, and the installation quality on one affects the performance of the other. Here is what to look for.
- Licensed for both: In Nevada, HVAC installation requires a C-21 (Refrigeration and Air Conditioning) license. Verify the contractor's license is current and covers both heating and cooling work. See our guide on Nevada HVAC contractor license types.
- Manufacturer authorization: A dealer authorized by the equipment manufacturer (Lennox Premier Dealer, Carrier Factory Authorized, Trane Comfort Specialist, etc.) has completed manufacturer training and can offer extended warranties that non-authorized installers cannot.
- Manual J load calculation: Any contractor who quotes you a system size without performing a load calculation is guessing. Oversized systems short-cycle. Undersized systems run constantly. Both waste energy and reduce equipment life. A proper load calculation takes 30-60 minutes and accounts for your home's square footage, insulation, window orientation, and ductwork.
- Written quote with AHRI reference number: The quote should specify the exact model numbers of both outdoor and indoor units and include the AHRI reference number confirming they are a matched pair. If the quote just says "3-ton 16 SEER system" without model numbers, ask for specifics.
- At least three bids: Get quotes from at least three licensed contractors. Compare not just price but scope — what is included in the quote, what is extra, what warranty is offered, and whether the contractor handles the permit and NV Energy rebate paperwork. Our questions to ask before buying a new HVAC system guide gives you the exact checklist.
The Cooling Company is a Lennox Premier Dealer with a 4.9-star rating from 740+ reviews. We provide free in-home assessments, Manual J load calculations, written quotes with AHRI-matched model numbers, and we handle all permitting and NV Energy rebate paperwork as part of every installation. Call (702) 567-0707 or request a quote online.
Maintenance After a Bundled Replacement
New equipment does not mean zero maintenance. Protecting your investment requires a consistent maintenance schedule — and the good news is that maintaining matched systems is simpler than maintaining mismatched ones.
We recommend enrolling in a maintenance plan that covers both systems. A twice-annual tune-up — once before summer (AC focus) and once before winter (furnace focus) — keeps your warranty valid, catches small issues before they become expensive repairs, and ensures your system continues to deliver its rated efficiency.
The most common maintenance items for a newly installed bundled system:
- Filter replacement: Every 30-90 days depending on filter type, pets, and dust levels. Las Vegas desert dust clogs filters faster than average.
- Coil cleaning: Annual professional cleaning of the outdoor condenser coil (desert dust, cottonwood, and landscape debris) and indoor evaporator coil.
- Refrigerant check: Verify charge annually. A new system should not lose refrigerant, but verifying confirms no installation defects.
- Furnace combustion analysis: Annual check of gas pressure, flame characteristics, and carbon monoxide levels at the heat exchanger.
- Thermostat calibration: Verify the thermostat reading matches actual room temperature and that programming is optimized for your schedule.
Neglecting maintenance on a new system voids most manufacturer warranties and can reduce system efficiency by 5-15% within the first two years — undoing the efficiency gains you paid for with matched equipment.
Frequently Asked Questions
Is it cheaper to replace AC and furnace at the same time?
Yes. Bundling typically saves $1,000-$2,500 compared to doing them as separate projects. The savings come from reduced labor (one crew, one visit), a single permit instead of two, shared ductwork assessment, and manufacturer package pricing on matched equipment. The larger and more complex the system, the greater the bundle savings.
How much does it cost to replace AC and furnace together in Las Vegas?
A bundled AC + furnace replacement in Las Vegas costs $9,500-$14,500 for a typical 3-ton system, installed. The price depends on efficiency tier (14-20+ SEER2 for AC, 80-97% AFUE for furnace), brand, and installation complexity. NV Energy PowerShift rebates can reduce net cost by $600-$1,800. For larger homes needing 4-5 ton systems, expect $10,800-$20,000.
Should I replace my furnace if my AC needs replacing?
It depends on the furnace's age and condition. If your furnace is 10+ years old, replacing it with the AC saves money through bundled labor and matched-system efficiency. If your furnace is under 5 years old and in good condition, keep it and replace only the AC. For furnaces in the 5-10 year range, get a professional condition assessment to determine remaining useful life.
Do I need to replace the furnace to get a matched system?
Not always. If your furnace was manufactured by the same brand family as your new AC and the specific model combination is AHRI-certified as a matched pair, you may already have a match. Your contractor can look up the AHRI reference number using both model numbers. However, if your furnace is from a different manufacturer or generation, it almost certainly will not be matched with a new condenser.
How long does it take to install both an AC and furnace?
A standard bundled installation in a single-story Las Vegas home takes 6-10 hours — typically completed in one day. Two-story homes, attic installations, or jobs requiring ductwork modifications may take 1.5-2 days. The entire process, from assessment to final inspection, takes about 1-2 weeks including permit scheduling.
Can I get NV Energy rebates for both AC and furnace?
Yes. NV Energy PowerShift rebates apply separately to qualifying AC units ($300-$1,200 for 16+ SEER2) and qualifying furnaces ($300-$500 for 95%+ AFUE). When you bundle, you can claim both rebates on the same project, potentially receiving $600-$1,800 total. Your contractor handles the rebate application paperwork.
Is there a federal tax credit for replacing AC and furnace in 2026?
No. The federal Section 25C energy efficiency tax credit was terminated for 2026 installations under the One Big Beautiful Bill Act. Installations completed before the cutoff date may still qualify if they meet the previous requirements, but new installations in 2026 do not. NV Energy PowerShift rebates are now the primary financial incentive for high-efficiency HVAC equipment in Las Vegas.
Should I switch to a heat pump instead of replacing both AC and furnace?
For many Las Vegas homes, yes. A heat pump replaces both systems with one unit, typically costs $7,500-$12,650 installed (3-ton), and qualifies for the highest NV Energy rebate tier ($500-$2,000). Heat pumps are especially cost-effective in Las Vegas because our mild winters (rarely below 25 degrees) are well within a modern heat pump's efficient operating range. The main consideration is whether your home's electrical panel can support the heat pump without an upgrade.
What SEER rating should I get when bundling AC and furnace?
For Las Vegas, 16 SEER2 is the sweet spot for value — offering strong energy savings without premium pricing. Systems rated 18-20 SEER2 make financial sense if you plan to stay in the home 10+ years, as the higher upfront cost is offset by greater annual savings in our extreme climate. Below 16 SEER2, you are leaving significant energy savings on the table. See our SEER2 ratings guide for the full analysis.
How long will a new AC and furnace last in Las Vegas?
A properly installed and maintained AC lasts 12-18 years in Las Vegas (shorter than the national average due to extreme runtime hours). A gas furnace lasts 15-25 years. Variable-speed and two-stage systems generally last longer than single-stage because they operate under less mechanical stress. Regular maintenance is the single biggest factor in equipment longevity.
What is the best time of year to replace AC and furnace in Las Vegas?
Spring (March-May) and fall (October-November) are the best times. Contractors are less busy than during summer emergency season, so you have more scheduling flexibility and may find promotional pricing. You also avoid the risk of being without AC during a 110+ degree day or without heat during a cold snap. Read our best time to buy a new AC guide for seasonal pricing trends.
Can I finance both an AC and furnace together?
Yes. Most HVAC financing covers the full project cost, whether that is one system or two. Bundling actually makes financing more attractive because the monthly payment increase from adding the furnace is modest ($40-$80/month on a 60-month term) while you get the full bundle savings. The Cooling Company offers zero-down financing with terms from 12 to 144 months and options for all credit tiers.
Will replacing both systems increase my home's value?
Yes, but the return varies. A new, matched HVAC system is a strong selling point in the Las Vegas real estate market, where buyers are keenly aware of cooling costs. Industry estimates suggest HVAC replacement recoups 50-75% of its cost at resale. More importantly, an aging or failing HVAC system is one of the most common deal-killers in Las Vegas home inspections — replacing both systems before listing eliminates that risk entirely.
The Bottom Line: Make the Decision That Fits Your Home
Replacing your AC and furnace together saves money, improves efficiency, and reduces hassle — when the timing is right. The $1,000-$2,500 in bundle savings, combined with matched-system efficiency gains and stacked NV Energy rebates, make it the clear choice when both systems are aging. But forcing a bundle when your furnace has years of life remaining wastes money that could be better spent elsewhere.
The right answer depends on your specific equipment ages, conditions, budget, and goals. A good contractor will help you evaluate every option honestly — not just push the most expensive project.
