A gas furnace replacement in Vancouver WA runs $6,400 to $13,300 installed in 2026. Standard 80% AFUE: $6,400 to $8,400. High-efficiency 95%+ AFUE two-stage: $8,600 to $11,400. Premium variable-speed modulating: $9,600 to $13,300, depending on home size. These are real installed ranges including equipment, labor, permits, and commissioning, reviewed August 2026. Venting, gas line work, and filtration add-ons are what push a quote toward the top of its range.
A furnace changeout is one of the most predictable jobs in HVAC, which is why we publish our pricing instead of hiding it behind a sales visit. The table below comes from the same pricing table our online estimator uses, and it is the same math our quotes are built on.
Real installed ranges by home size and tier.
These are turnkey Clark County numbers: equipment, labor, code venting, the gas connection, the permit, and full commissioning. They are real installed ranges, reviewed August 2026, not teaser pricing. Final pricing requires a 30-minute in-home measurement.
| Home size | Standard (80% AFUE) | High Efficiency (95%+ AFUE) | Premium (modulating) |
|---|---|---|---|
| Under 1,500 sq ft (60k BTU) | $6,400 to $8,000 | $8,600 to $10,900 | $9,600 to $12,000 |
| 1,500 to 2,500 sq ft (80k BTU) | $6,400 to $8,100 | $8,700 to $11,000 | $10,000 to $12,600 |
| 2,500 to 3,500 sq ft (100k BTU) | $6,600 to $8,300 | $9,000 to $11,300 | $10,200 to $12,900 |
| 3,500+ sq ft (120k BTU) | $6,700 to $8,400 | $9,100 to $11,400 | $10,600 to $13,300 |
The three tiers in plain terms:
- Standard (80% AFUE): single-stage heat, the lowest upfront cost. American Standard Silver 80. It turns 80% of the gas you buy into heat and sends the rest up the flue.
- High Efficiency (95%+ AFUE): two-stage heat, wastes far less gas than an 80% unit. This is the tier we install most and the one we recommend for most homes staying on gas.
- Premium (variable-speed modulating): modulating heat, the quietest and most even comfort. American Standard Platinum 95. It adjusts output continuously instead of cycling on and off.

What drives the price up or down.
1. Venting.
An 80% furnace vents hot exhaust through a metal flue. A 95%+ furnace runs cool enough to vent through PVC pipe, usually out a side wall, and it produces condensate that has to be drained properly. If your home is moving from an 80% unit to a 95%+ unit, the vent path changes, and if the old metal flue also serves a water heater, that flue sometimes needs rework too. A simple changeout with a clean vent path sits at the bottom of the range. New venting runs, long horizontal runs, or flue rework push a quote toward the top.
2. Gas line work.
Every install gets the gas connection done properly: a new sediment trap and a regulator as needed are routine and included. What adds cost is when the line itself needs attention, rerouting to a new furnace location, upsizing an undersized line, or replacing corroded pipe. We pressure-test and check for gas leaks before we leave regardless, that part is commissioning, not an add-on.
3. Filtration add-ons.
A furnace changeout is the cheapest moment to upgrade filtration, because the return side is already open. A media filter cabinet or a deeper filter rack takes a much thicker filter that lasts longer and catches more than the standard 1-inch throwaway. These are optional, priced as their own line items on the quote, and easy to say no to. If you are curious what the right filter schedule looks like afterward, see how often to change a furnace filter.
4. Size and sizing.
Bigger homes need more BTU, which is why the rows in the table step up. But the right size comes from a Manual J load calculation, not square footage alone. Oversized furnaces short-cycle, heat unevenly, and wear out faster. We run the load calculation on every quote.
Paying for it.
Monthly payments are available on approved credit, and many homeowners run a furnace replacement that way rather than paying the full installed price up front. See the financing page for how it works, or ask for the payment option on your quote.

What the installed price includes.
Every number in the table above covers the complete job, the way we actually run it:
- The furnace itself, sized from a Manual J load calculation, not a guess.
- Code-compliant venting, including condensate handling on high-efficiency units.
- The gas connection, with a new sediment trap and regulator as needed.
- Electrical hookup.
- The permit, pulled and inspected, with our license number on the quote.
- Commissioning and safety checks, including a combustion and gas-leak test before we leave.
A standard changeout is usually done in a single day. Jobs with new venting or gas-line work can take a bit longer, and we confirm the timeline in the written quote. For the play-by-play, read what to expect during an HVAC changeout.
Questions homeowners ask.
How much does a furnace replacement cost in Vancouver, WA?
$6,400 to $13,300 installed in 2026. Standard 80% AFUE runs $6,400 to $8,400, high-efficiency 95%+ AFUE runs $8,600 to $11,400, and premium modulating runs $9,600 to $13,300, depending on home size. These are real installed ranges including equipment, labor, permits, and commissioning, reviewed August 2026.
What drives the price up or down?
Beyond size and tier: venting (moving from 80% to 95%+ changes the vent path, and old flues sometimes need rework), gas line work (rerouting or upsizing the line adds labor and materials), and optional filtration add-ons like a media filter cabinet, which show up as separate line items.
Does the installed price include permits and commissioning?
Yes. The ranges here are turnkey: equipment, labor, code venting, the gas connection, the permit, and full commissioning with a combustion and gas-leak test. Monthly payments are available on approved credit, and a free 30-minute in-home measurement turns a range into a firm written quote.
The bottom line for Vancouver homeowners.
For most Clark County homes staying on gas, plan for $8,600 to $11,400 installed for a high-efficiency 95%+ AFUE furnace, the tier we install most. Standard 80% units start at $6,400 and premium modulating tops out at $13,300 for the largest homes. If a quote lands far outside those ranges in either direction, ask why before signing.
