AfterHow Much Does Furnace Replacement Cost in Las Vegas?
A full furnace replacement in Las Vegas typically runs between $3,800 and $7,200 for most single-family homes, with the average homeowner paying around $5,400 in 2026. That price includes the furnace unit, removal of the old system, installation labor, and a written guarantee. High-efficiency models or homes needing ductwork modifications can push the total toward $9,000 or more.
The final number depends on furnace size (measured in BTUs), efficiency rating, and whether your existing ductwork and gas lines are compatible. We’ll break down every line item below so you know exactly what you’re paying for before you sign anything.
Key Takeaways:
- Entry-level furnace replacement: $3,800 – $4,800
- Mid-range replacement (most common): $4,800 – $6,500
- High-efficiency replacement: $6,500 – $9,000+
- Labor alone: $1,200 – $2,400
- Old furnace removal and disposal: $150 – $400
Furnace Replacement Cost Breakdown (2026)
Here’s what a typical furnace replacement in Las Vegas looks like, item by item. These are real market ranges based on what we see across the valley, from Summerlin to Henderson.
| Line Item | Typical Range | Notes |
|---|---|---|
| Furnace unit (80% AFUE, single-stage) | $1,600 – $2,400 | Goodman, Rheem, York tier |
| Furnace unit (96% AFUE, two-stage) | $2,400 – $3,800 | Trane, Carrier, Lennox tier |
| Furnace unit (97 – 98% AFUE, modulating) | $3,800 – $5,500 | Top-efficiency models |
| Installation labor | $1,200 – $2,400 | Includes gas line connection, venting, electrical wiring, testing |
| Old furnace removal and disposal | $150 – $400 | Haul-away and proper disposal |
| Thermostat upgrade | $80 – $300 | Smart thermostats run higher |
| Ductwork modification or repair | $400 – $2,500 | Only if needed; many homes skip this |
| Permits | $75 – $250 | Required in Clark County |
In Las Vegas, most homes need a furnace in the 60,000 to 100,000 BTU range. A 1,500-square-foot single-story home typically needs 60,000 – 80,000 BTUs, while a 2,500-square-foot two-story might need 100,000 BTUs or more. Because our winters are mild compared to the Midwest, many Vegas homeowners can get away with a mid-efficiency unit and still stay comfortable through January’s cold snaps.
What Drives the Price Up or Down?
The single biggest variable is efficiency rating. An 80% AFUE furnace costs less upfront but wastes 20 cents of every gas dollar. A 96% AFUE furnace costs more now but cuts winter heating bills by 15 – 20%. For most Las Vegas homes, we recommend sticking with 90 – 96% AFUE. Our heating season is short, so the ultra high-efficiency modulating units rarely pay for themselves here the way they do in Minnesota or Michigan.
Location matters too. Homes in Summerlin and parts of Henderson with newer construction often have code-compliant venting and gas lines already in place, making the job straightforward. Older homes in the central valley or downtown neighborhoods may need venting retrofits, which add $300 – $1,200.
What Affects Furnace Replacement Pricing in Las Vegas
- Furnace size and BTU output. Bigger homes need bigger furnaces. A 100,000 BTU unit costs $400 – $900 more than a 60,000 BTU unit. But here’s what matters in Las Vegas: oversizing is a real problem. A furnace that’s too large short-cycles, wastes gas, and wears out faster. We see this constantly in tract-home neighborhoods where builders installed one size for every floor plan.
- Efficiency rating (AFUE). The jump from 80% to 96% AFUE adds roughly $800 – $1,400 to equipment cost. Over a 15-year lifespan in Las Vegas, that premium usually gets recovered through lower gas bills, but the payback window is longer here than in colder climates.
- Brand and equipment tier. Goodman and York are the value tier. Trane, Carrier, and American Standard sit in the mid-to-premium range. Daikin and Lennox fall in between. The same-size furnace can vary by $1,000 solely on brand. We service all of them and will tell you straight: the installer matters more than the badge on the cabinet.
- Venting and gas line condition. Older Las Vegas homes built before 1990 often have galvanized venting that needs replacement when a new high-efficiency furnace is installed. High-efficiency units vent through PVC rather than metal, and retrofitting that costs $300 – $1,200 depending on furnace location.
- Furnace location and accessibility. A furnace in a ground-floor closet is an easy install. A furnace in a cramped attic with limited clearance adds labor time. Attic installs in Las Vegas are common in houses built in the 1990s and 2000s, and summer heat makes that workspace brutal. Expect $200 – $500 in extra labor for difficult access.
- Code compliance and permits. Clark County requires a mechanical permit for furnace replacement. A reputable contractor pulls it every time. The permit costs $75 – $250, and skipping it can void your homeowner’s insurance if something goes wrong.
How Long Does a Furnace Replacement Take?
Most furnace replacements in Las Vegas are finished in one day. A straightforward swap in a home with compatible venting takes 4 to 8 hours. That includes shutting off gas, removing the old unit, setting the new furnace, connecting gas and electrical, testing combustion, and walking you through the new thermostat.
If ductwork modifications or venting retrofits are required, expect a second day. We always give you a written timeline and a written price before any work starts. No surprises at the end of the day.
What Happens on Installation Day
- Technician introduction. You get the technician’s name and photo before they arrive, through the Threshold Verified standard. When they knock, they’ll show photo ID at the door before stepping inside.
- Workspace protection. Drop cloths and shoe covers go down. The furnace area gets sectioned off from the rest of the house.
- Gas shutoff and old unit disconnect. Gas is cut at the shutoff valve. The old furnace is disconnected from gas, electric, and venting.
- Old furnace removal. The dead unit is hauled out and properly disposed of. This is included in the quote.
- New furnace placement and connection. The new unit is set, leveled, and connected to gas, electrical, and venting. A new filter goes in.
- System testing and commissioning. We fire the furnace, check gas pressure, verify the flame sensor and heat exchanger, and confirm the thermostat cycles correctly.
- Walkthrough and paperwork. You get a written summary of what was installed, what the guarantee covers, and exactly what you paid. Every Brandt HVAC job includes a written price and a written guarantee. If anything fails within the guarantee period, we come back free under the 365-Day Done Right Promise.
How to Save on Furnace Replacement
You don’t have to overspend on a furnace replacement in Las Vegas. Here’s what actually works:
- Replace during spring or fall. HVAC companies in Las Vegas are at their busiest in December and January, when furnaces fail during cold snaps. Scheduling a replacement in March or October often means better availability and occasionally better pricing, since shops are slower.
- Get a manual-J load calculation. The cheapest mistake is buying the wrong size. A contractor who sizes by “rules of thumb” may sell you a furnace that’s too big. A proper load calculation tells you exactly how many BTUs your home needs. It prevents paying for capacity you’ll never use.
- Skip the ultra high-efficiency tier. In Las Vegas, a 96% AFUE furnace is the sweet spot. The 98% modulating units cost $1,500 – $2,500 more and rarely justify that premium in a city where the furnace runs for maybe 1,000 hours per year.
- Ask about manufacturer rebates. Trane, Carrier, and others run seasonal rebates that can knock $100 – $400 off the equipment cost. A good contractor files the paperwork for you.
- Check your gas utility for efficiency incentives. Southwest Gas occasionally offers rebates for high-efficiency furnace installations. These change year to year, but it’s worth five minutes to check.
- Get a written estimate before you agree to anything. Every Brandt HVAC job starts with a written price. You see the full cost, line by line, before any work begins. Call (725) 502-1353 for a free estimate and we’ll walk you through the numbers in plain language.
Furnace Replacement vs. Furnace Repair: Which One Do You Need?
This is the question every Las Vegas homeowner faces when a furnace acts up in December. Here’s the honest math:
- Repair costs under $700 and the furnace is under 10 years old: Repair it. A furnace repair in Las Vegas typically runs $150 – $700, and a unit that’s under a decade old usually has years of life left in the heat exchanger.
- Repair costs over $700 and the furnace is over 15 years old: Replace it. Spending half the cost of a new system on a furnace that’s near the end of its lifespan doesn’t make sense. The heat exchanger, the most expensive component, is often the first thing to go on aging units.
- The heat exchanger is cracked: Replace the furnace. A cracked heat exchanger is a carbon monoxide risk. This is a safety issue, not a budget question. Don’t patch it.
For a full walkthrough of what’s involved, see our Furnace Replacement in Las Vegas page. And if you’re unsure whether to repair or replace, we’ll give you a straight answer. We’re happy to tell you a repair is all you need, because the only thing worse than paying for a new furnace you didn’t need is paying for a patch job on a furnace that should have been replaced.
Furnace Brands We Install in Las Vegas
We install and service all major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Here’s the honest breakdown of what you’re paying for with each tier:
- Value tier (Goodman, York): $1,600 – $2,800 for the unit. Solid engineering, fewer bells and whistles, shorter parts warranties. A fine choice for a rental property or a home you plan to sell soon.
- Mid tier (Bryant, Rheem, Daikin): $2,200 – $3,500 for the unit. Good balance of price, efficiency, and warranty coverage. This is where most Las Vegas homeowners land.
- Premium tier (Trane, Carrier, Lennox, American Standard): $3,000 – $5,500 for the unit. Longer parts warranties, better heat exchanger designs, and stronger dealer networks. You pay for the badge, but the badge does mean something in terms of parts availability and build quality.
We don’t push one brand over another. We price the options, explain the differences, and let you decide. The installation quality matters more than the brand name on the cabinet, which is why our technicians are background-checked, identity-verified, and sent to you by name and photo before every visit.
Permits and Code Requirements in Las Vegas
Clark County and the City of Las Vegas require a mechanical permit for furnace replacement. Your contractor pulls the permit, schedules the inspection, and stands behind the work. The permit fee is typically $75 – $250, and it’s a line item on your invoice.
Here’s what the inspector checks: gas line sizing, combustion air supply, venting configuration, electrical connection, and condensate drainage for high-efficiency units. A furnace that fails inspection costs you time and money. Ours pass, and if anything doesn’t, we come back and fix it. That’s covered under the 365-Day Done Right Promise.
FAQs – Furnace Replacement Cost
How much does a furnace replacement cost in Las Vegas?
Most furnace replacements in Las Vegas cost between $3,800 and $7,200. The average is around $5,400. High-efficiency units or homes needing ductwork changes can reach $9,000 or more.
Is it cheaper to repair or replace a furnace in Las Vegas?
If the repair is under $700 and your furnace is under 10 years old, repair is cheaper. If the repair exceeds $700 on a furnace over 15 years old, replacement usually makes more financial sense. A cracked heat exchanger always means replacement, for safety. Call (725) 502-1353 and we’ll give you an honest assessment based on your specific unit.
How much does a high-efficiency furnace cost to install in Las Vegas?
A high-efficiency furnace (96 – 98% AFUE) installed in Las Vegas runs $6,500 to $9,000+, equipment and labor included. The price premium over a standard 80% unit is about $800 – $1,400 for equipment plus possible venting retrofits.
Can you replace a furnace the same day in Las Vegas?
Yes, in most cases. A straight replacement with no ductwork changes takes 4 to 8 hours, and we can usually schedule it same-day or next-day when you call. Furnace failures happen at the worst times, and our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail, no callback queue.
What size furnace do I need for my Las Vegas home?
A 1,200 – 1,500 square foot Las Vegas home typically needs 60,000 – 80,000 BTUs. A 2,000 – 2,500 square foot home usually needs 80,000 – 100,000 BTUs. The only way to know for sure is a manual-J load calculation, which we include free as part of our estimate. Sizing by square footage alone leads to oversized furnaces that short-cycle and waste gas.
