A new furnace is one of the most important investments you'll make in your Utah home. Get it right — correct sizing, proper installation, right efficiency level for your home — and it will keep your family warm and comfortable for 15 to 20 years while keeping your Dominion Energy or Questar gas bill as low as possible. Get it wrong, and you'll spend years dealing with uneven heating, excessive bills, and premature equipment failure.
Salmon HVAC has been installing furnaces in Northern Utah since 1979. As a Daikin Comfort Pro Authorized Dealer, we have access to the full Daikin line — including their 98% AFUE modulating furnaces — as well as the expertise to properly size and install any system we sell. Every installation comes with a 1-year labor warranty and up to 10-year parts warranty on qualifying Daikin equipment.
Signs You Need a New Furnace
- Your furnace is 15+ years old — The average gas furnace lasts 15–20 years with maintenance. If yours is in that range, replacement is worth planning for — ideally before an emergency failure on a January night.
- Facing a major repair on an aging system — A heat exchanger replacement, inducer motor, or control board on a furnace over 15 years old rarely makes financial sense. The repair cost often approaches or exceeds the value of the equipment.
- Your furnace is 80% AFUE or lower — If you have an older 80% AFUE furnace, upgrading to 96% AFUE means you're using 16% less gas for the same amount of heat. Over a Utah heating season, that can mean $150–$300 in annual savings depending on your home's size.
- Uneven temperatures throughout the house — Hot and cold spots can result from a furnace that's oversized, undersized, or has a failing variable-speed blower. A properly sized replacement solves the problem from day one.
- Frequent repairs over the past few years — A furnace that's needed two or three repairs in recent years is giving you signals about what's coming. Replacing before the next failure gives you control over timing and options.
- Your current furnace doesn't have two-stage or variable-speed operation — If you have an old single-stage furnace, you've been living with temperature swings, noisy operation, and excess energy use. Modern variable-speed systems are dramatically more comfortable and efficient.
Choosing the Right Furnace for Your Utah Home
There's no one-size-fits-all answer. Here are the key decisions every Utah homeowner faces when choosing a new furnace:
- AFUE efficiency rating — 80% AFUE units have lower upfront costs but higher operating costs. 96% AFUE units cost more initially but save on monthly bills and qualify for Dominion Energy ThermWise rebates. At Utah's natural gas prices and heating season length, the payback on a 96% vs. 80% unit is typically 4–6 years.
- Single-stage vs. two-stage vs. variable-speed — Single-stage furnaces operate at 100% capacity or off, creating temperature swings. Two-stage furnaces run at 60–65% capacity most of the time and only ramp to 100% on the coldest days — quieter and more efficient. Variable-speed furnaces with modulating gas valves provide the most consistent temperatures and highest efficiency, at a higher upfront cost.
- Correct BTU sizing — An oversized furnace short-cycles, causing uneven temperatures and excess wear. An undersized one can't keep up on the coldest nights. We perform a Manual J heat load calculation on every installation to determine exactly what size your home needs.
- Gas line and venting requirements — High-efficiency (96%+ AFUE) furnaces use PVC condensate venting instead of traditional flue venting. If you're switching from 80% to 96%, new venting is required. We handle all permitting and code compliance.
Our Furnace Installation Process
- Free in-home estimate — We measure your home, evaluate insulation, assess duct system condition, and use Manual J to determine the correct furnace size. This takes about an hour and is completely free.
- Equipment selection — We walk you through options from Daikin and other major brands, explain the efficiency and comfort differences, and give you honest recommendations based on your home's specific needs and your budget.
- Professional installation with permits — We pull all required permits, disconnect the old system, install the new furnace, connect gas, electrical, and venting per code, and handle disposal of the old equipment.
- System commissioning and testing — We verify gas pressure, test ignition and flame sensing, check temperature rise across the heat exchanger, verify limit switches and safety controls, and confirm the system operates correctly across all stages.
- Warranty registration and walkthrough — We register your equipment warranty directly with the manufacturer and walk you through thermostat operation, filter location, and what to expect in the first heating season.

Furnace Installation Cost in Utah
Furnace installation in Northern Utah typically runs $2,500–$6,000 depending on system size, efficiency level, and installation complexity:
- 60,000–80,000 BTU, 96% AFUE, single-stage: $2,800–$4,000
- 80,000–100,000 BTU, 96% AFUE, two-stage: $3,500–$5,000
- 80,000–100,000 BTU, 97–98% AFUE, variable-speed: $4,500–$6,500
- Venting modifications (when switching to high-efficiency): $300–$800 additional
- Ductwork repairs or modifications: $500–$2,000 depending on scope
Dominion Energy ThermWise rebates ($100–$250 for qualifying high-efficiency systems) and federal IRA tax credits of up to $600 for qualifying furnaces can reduce the net cost. We'll walk you through what you qualify for at the time of estimate.
Frequently Asked Questions
How much does furnace installation cost in Utah?
Furnace installation in Northern Utah typically runs $2,500–$6,000, depending on the size of your home, whether it's a single-stage, two-stage, or variable-speed system, and the efficiency rating. A standard 80,000 BTU, 96% AFUE single-stage furnace for a typical Utah home falls in the $3,000–$4,500 range installed. Dominion Energy ThermWise rebates and IRA tax credits can reduce the net cost.
What AFUE rating should I choose for a Utah furnace?
We recommend 96% AFUE or higher for most Northern Utah homes. At 96% AFUE, only 4% of the gas you burn is lost up the flue — compared to 20% with an 80% AFUE unit. In Utah where natural gas heating runs 5–6 months of the year, the efficiency difference is meaningful on your monthly bill, and high-efficiency units qualify for ThermWise rebates.
How long do furnaces last in Utah?
A well-maintained gas furnace typically lasts 15–20 years. Utah's dry climate is actually gentler on heat exchangers than humid climates, but altitude can affect burner performance over time if not tuned properly during installation. Annual maintenance is the single biggest factor in reaching the upper end of that lifespan.
Should I get a variable-speed furnace?
Yes, in most cases. A variable-speed blower motor runs continuously at low speed rather than cycling on and off at full blast. This provides more consistent temperatures throughout your home, better air filtration (because the filter is always running), and lower electricity consumption. It's also significantly quieter. The upfront cost is $500–$1,000 more than a single-stage unit, but the comfort and efficiency gains are substantial over the furnace's lifetime.
