60K BTU, 80% AFUE single-stage | $4,200–$5,600 |
80K BTU, 80% AFUE single-stage Most common Utah job | $4,800–$6,400 |
80K BTU, 96% AFUE two-stage | $6,200–$8,200 |
100K BTU, 96% AFUE variable-speed | $7,800–$9,600 |
Variables
What changes the number
These are the specific factors that move your quote up or down within the range above. Knowing them lets you compare quotes apples-to-apples instead of guessing.
AFUE efficiency rating
+$1,400–$2,600 for 96%+ tier80% AFUE = standard, lower upfront cost. 96%+ AFUE = high-efficiency, lower gas bills (~15–20% savings), qualifies for IRA credit + utility rebates. Math usually favors 96%+ for homes that run heat 5+ months/year.
BTU output (size)
$300/15K BTU stepSized via Manual J. Utah elevation requires altitude derating: a 100,000 BTU rated furnace at sea level outputs about 90,000 BTU at 4,500 ft. Most Utah homes need 60,000–100,000 BTU.
Vent type
+$200–$700 for vent reroute80% AFUE uses metal B-vent (existing chimney usually works). 96%+ AFUE uses 2-pipe PVC sidewall vent (we run new pipe through the wall). Switching from metal to PVC adds labor.
Variable-speed vs. single-stage blower
+$400–$900Variable-speed ECM blower runs quieter, dehumidifies better when paired with AC, and reduces electrical consumption. Worth it for new builds and homes with multi-zone setups.
Existing duct + plenum condition
+$300–$1,200If existing supply/return plenum is undersized or rusted, we modify or replace as part of the install.

FAQ
Frequently asked questions
Should I replace my furnace with another furnace, or switch to a heat pump?
+
Depends on your gas vs. electric rate, climate exposure, and whether you have ductwork. Most Utah homes still benefit from a dual-fuel setup (heat pump + gas furnace backup) over heat-pump-only because nighttime winter temps below 5°F are common and gas heat is reliable + cheap. We model the math on every quote.
Do I need to upsize my gas line for a new furnace?
+
Almost never. Most existing 1/2" or 3/4" black-iron gas lines can handle a 100K BTU furnace if the run length is reasonable. We size and pressure-test on every install. The exception is when pairing a furnace with a tankless water heater + range — total demand can exceed the existing line's capacity.
What's the difference between 80% and 96% AFUE in dollar terms?
+
On an average Utah heating bill ($800/year for gas heat), a 96%+ furnace saves about $130/year vs. 80%. Over 15 years that's ~$2,000 in fuel savings. The 96% upgrade costs $1,400–$2,600 more upfront, but stacks $500–$1,100 in rebates + tax credit. Net break-even: 4–6 years.
