Furnace Prices (2026): By Brand & Size

By HomeCost Guide · Updated October 2026 · unit-only average for a mid-tier gas furnace; $4,800 is the typical installed all-in price

Furnace prices for the equipment alone run $1,700 to $6,000 depending on brand tier, size, and efficiency — and $2,800 to $10,000 once professional installation is included. Understanding the unit price matters because it's roughly half of every installed quote, and knowing what the box should cost is your best defense against an inflated bid. The price ladder has three rungs: budget-tier brands ($1,700–$3,000 for the unit), mid-tier workhorses ($2,800–$5,000), and premium lines ($4,000–$7,000+) — with size (BTU capacity) and efficiency (AFUE) moving prices within each tier. Here's the uncomfortable truth the industry won't volunteer: reliability differences between major brands are modest, and installation quality predicts your furnace's lifespan better than the name on the cabinet. This guide breaks down real unit prices by tier and size, so you can spot a fair quote and stop overpaying for a badge. We also explain why installation quality matters more than the brand badge, and how to split any quote into equipment versus labor so you can see exactly what you're paying for.

1. Furnace Prices (2026): By Brand & Size cost breakdown

Two things to notice: price climbs with size in fairly predictable $300–$600 steps per 20,000 BTU, and the brand-tier premium is real but buys you mostly warranty length and features — not a fundamentally different machine. A mid-tier 80,000 BTU furnace from a reputable installer beats a premium unit from a sloppy one every time. Spend your comparison energy on the installer's quote detail, not the brand brochure.

Where the money goes: labor vs materials vs fees

• Furnace unit (equipment)$1,700–$6,000Budget tier: $1,700–$3,000. Mid-tier: $2,800–$5,000. Premium: $4,000–$7,000. The unit is typically 40–55% of the installed total — if a quote's equipment line looks wildly off these bands, ask for the model number and check it.
• Installation labor$1,000–$2,500A full day for a two-person crew on a standard swap. This is the part of the price that varies most by contractor — and the part where quality differences actually live.
• Venting, gas, and electrical$300–$2,000High-efficiency venting conversions, gas line work, condensate drains, and any panel upgrades. Often the fuzziest part of quotes — demand line items.
• Permits, removal, thermostat$250–$900Mechanical permit ($100–$400), old-unit haul-away ($50–$300), and thermostat ($0–$300 depending on what's included). Small individually, but they add up to real money.

2. Signs you're overpaying for a furnace

Signs you're overpaying for a furnace

• The quote lists only a brand name with no model number — you can't verify the specs or the fair unit price.
• Equipment is priced 50%+ above the unit bands in this guide with no explanation of what's special about it.
• You're quoted a premium-tier unit when a mid-tier matches your needs — the badge premium rarely pays back.
• The BTU size jumped two tiers above your old unit with no load calculation to justify it.
• A single combined price with no equipment/labor split — bundling hides equipment markup.
• The 'discount' expires today. Real equipment pricing doesn't work that way.

3. How to price-shop a furnace correctly

How to price-shop a furnace correctly

1. Determine your BTU need. Get a Manual J load calculation (or at minimum, a careful assessment) so you know your target size range — 60,000 vs 100,000 BTU is a $1,000+ unit-price difference. Never price-shop without knowing your size.
2. Pick your tier and efficiency. Decide budget/mid/premium and 80% vs 95%+ AFUE based on climate and how long you'll own the home. This narrows the field from dozens of models to a handful.
3. Get model-specific quotes. Ask each contractor for the exact model number they're quoting. Identical model numbers across bidders is the only true apples-to-apples comparison — same box, different installer, different labor price.
4. Split equipment from labor. Ask each bidder to break out equipment cost versus labor and extras. The equipment should land in similar bands across quotes; big divergences reveal who's marking up the box.
5. Verify and negotiate. Check model numbers against manufacturer spec sheets (AFUE, staging, warranty). Then negotiate on the labor portion and extras — that's where legitimate margin lives, and where honest contractors have room to move.

4. What affects the cost

Brand tier: budget vs mid-tier vs premium

Budget-tier brands price units at $1,700–$3,000 — solid basic equipment with shorter warranties and fewer frills. Mid-tier lines ($2,800–$5,000 per unit) add better warranties (usually 10-year parts), quieter operation, and more staging options; this is the value sweet spot for most buyers. Premium lines ($4,000–$7,000+) bring the longest warranties and top-end fit and finish. The honest assessment: core components are comparable across tiers from major manufacturers. You're paying for warranty length, features, and dealer network — worthwhile at the mid-tier step, diminishing returns above it.

BTU capacity

Size is priced in tiers: expect roughly $300–$600 more per 20,000 BTU step. A 60,000 BTU unit might run $2,200–$4,000 while the 100,000 BTU version of the same model runs $3,000–$5,500. This is why correct sizing saves money twice — a right-sized smaller furnace costs less to buy and less to run than an oversized one. Contractors who quote without a load calculation often default one size up 'to be safe,' quietly adding $500–$1,000 to your equipment cost for their peace of mind, not your benefit.

AFUE efficiency rating

Efficiency is the second price dimension after size: 80% units are cheapest, 92–96% mid-range, 97–98% premium — roughly $1,000–$2,000 per step for the same brand and size. The premium buys condensing heat exchangers, sealed combustion, and usually multi-stage operation. In cold climates the fuel savings justify it; in mild ones they often don't. One pricing nuance: high-AFUE units also cost more to install (PVC venting, condensate management), so the true step-up cost is equipment premium plus $500–$1,200 in added labor.

Staging and blower technology

Single-stage units are the price floor. Two-stage adds $500–$1,200 to the unit price; modulating burners add $1,500–$2,500. Variable-speed ECM blowers add $400–$800 over basic PSC motors but cut electricity use up to 75% and run quieter — one of the few options that pays for itself in most climates. When a quote jumps unexpectedly between bidders, staging and blower differences are often the hidden cause: make sure you're comparing the same technology, not just the same brand.

Heat exchanger warranty

The heat exchanger is the furnace's core — and its most expensive part to replace. Budget lines typically offer 20-year heat-exchanger coverage; mid-tier offers lifetime; premium lines offer lifetime with replacement-unit guarantees. Since heat-exchanger failure is what usually kills a furnace, warranty length here is the most meaningful spec difference between tiers. Read the registration terms: many lifetime warranties require online registration within 60–90 days, defaulting to much shorter coverage if you forget.

Where you buy: dealer vs distributor vs online

Most furnaces sell through authorized dealers who bundle equipment and installation — the standard and recommended path, since manufacturer warranties often require professional installation. Some homeowners buy units online or through distributors for $200–$500 less, but then face warranty complications (many manufacturers void or limit warranties on internet-purchased equipment) and the challenge of finding an installer willing to warranty labor on customer-supplied equipment. The small savings rarely survive the added risk.

Regional pricing variation

Equipment wholesale prices are fairly national, but installed prices swing 20–40% by region on labor alone. High-cost metros (NYC, Bay Area, Boston) add $800–$1,500 to typical installed totals versus the Southeast or Midwest. Local code requirements — seismic strapping, condensate freeze protection, combustion-air rules — add their own increments. And in oil-heavy New England, gas equipment can carry a small premium simply because fewer dealers stock it. Always benchmark against local quotes, not national unit prices alone.

Time of year

Manufacturers and distributors run promotions in shoulder seasons (spring and fall) to keep installers busy — expect $200–$600 in seasonal incentives on mid-tier and premium lines. Conversely, January emergency replacements pay full sticker plus premium labor. If your furnace is aging but alive in September, that's the buying window: promotions are active, installers have schedule flexibility, and you're negotiating from strength instead of shivering.

What's bundled with the unit

Unit prices aren't always comparable because bundling differs: one quote's '$3,200 furnace' includes a new thermostat, condensate pump, and 10-year labor warranty; another's '$2,800 furnace' includes none of those. Thermostats ($150–$300), extended labor warranties ($200–$500), and IAQ add-ons (media filters, UV lights) are the usual bundle variables. Demand an itemized breakout — 'furnace: [dollar amount], thermostat: [dollar amount], extras: [dollar amount]' — before comparing any two numbers.

Rebates and tax credits

The effective price of a high-efficiency furnace drops meaningfully after incentives: the federal 25C credit returns up to $600 on qualifying models, and utility rebates add $200–$800 in many territories. Some utilities also offer 0%-interest loans for efficiency upgrades. These incentives phase and change — 2026 rules differ from 2024 — so verify current eligibility for your specific model before signing. A mid-tier 96% unit after credits can cost less net than a budget 80% unit, flipping the value calculation entirely.

5. Saving money & hiring right

Questions to ask your contractor

• What's the exact model number, and can I see the manufacturer's spec sheet?
• Break out equipment cost versus labor and extras — what am I paying for the box alone?
• Is this quote for single-stage, two-stage, or modulating — and is the thermostat compatible?
• What are the parts and labor warranty terms, including registration deadlines?
• Which rebates or tax credits does this specific model qualify for?
• If I drop one BTU tier based on the load calculation, how much do I save?

6. How costs vary by state

Unit prices are fairly national at wholesale, so state differences in installed furnace prices come mostly from labor rates, permit costs, and code requirements. The equipment bands in this guide hold everywhere — it's the labor line that moves.
