A furnace replacement in Utah typically costs $3,000–$6,500 installed in 2026, with premium variable-speed systems reaching $10,000 — these are the ranges our own recent installs actually sold for, not inflated internet averages. Where your home lands depends on the efficiency tier, the staging, what your venting requires, and whether the installer applies the high-altitude corrections Utah homes need. The ranges below are market-wide — your written quote from us is often lower, and if you already have a bid, we’ll beat it on the same scope or leave.
| System | Typical Utah market range* |
|---|---|
| 80% AFUE single-stage (reuses metal flue) | $3,000 – $4,500 |
| 96% AFUE single-stage | $4,000 – $5,500 |
| 96% AFUE two-stage — the Utah sweet spot | $4,500 – $6,500 |
| Modulating / variable-speed | $7,000 – $10,000 |
| Furnace + AC replaced together (full system) | $9,000 – $12,000 |
*Typical installed ranges based on our own recent Utah jobs — your exact quote depends on your home. Your written AYSP quote is often lower: bring us any competing bid and we beat it on the same scope or leave.
Gas burned for the same heat
Annual fuel input, indexed — lower is better
A 96% AFUE furnace extracts more heat from every therm — roughly 16% less gas for the same warmth.
The Tiers, Plainly
Which tier fits your house is the real question — our staging comparison walks through it honestly.
The Five Things That Move the Price
- Venting. A 96% condensing furnace needs PVC venting and a condensate drain. Converting from a metal B-vent chimney adds real labor — the #1 cause of quote differences between homes.
- High-altitude orifice kit. At 4,500+ ft, furnaces must be derated to burn cleanly. It’s the line item that tells you whether an installer knows Utah.
- Staging. Two-stage is the biggest comfort upgrade per dollar for two-story homes.
- Ductwork corrections. Undersized returns are endemic in 1990s–2000s Utah builds; a return-air fix can matter more than the next equipment tier.
- Warranty depth. Ten-year parts coverage (standard on our installs) beats the base coverage many quotes carry.
Rebates Still Available in 2026
The federal 25C tax credit ended December 31, 2025 — but Enbridge Gas Utah’s ThermWise program is still live for high-efficiency furnaces and smart thermostats installed in 2026. We put the current rebate number in your written quote and file the paperwork, and 0% financing turns the project into a monthly payment.
Repair or replace? The 50% rule
If the repair quote is more than half the cost of a comparable new furnace AND the unit is past 12 years — replace. Under 12 years with a sound heat exchanger — repair. Full logic in our repair vs replace guide.

- A Manual J load calculation with elevation correction — not a “same size as the old one” guess
