Heat Pump vs Furnace
Heat pumps move heat; furnaces burn gas to make it. Which is right for a Utah home depends on elevation, electric rates, and the up-to-$2,000 utility rebates still on the table.
Heat Pump
Refrigerant-cycle heating + cooling, one unit
- Heating AND cooling from one piece of equipment
- Cold-climate models work efficiently to -15°F (Utah's coldest design temp)
- Rocky Mountain Power wattsmart rebate up to $2,000 — still active in 2026 (federal tax credits ended Dec 2025, the utility rebate did not)
- 2x-3x the heating efficiency of a gas furnace (COP 2.5-3.5 vs 0.92)
- Lower carbon footprint as the Utah grid greens
- Higher upfront cost than furnace
- Backup heat needed below your model's economic balance point (usually 15-25°F)
- Sized differently than a gas furnace — heat pumps benefit from low-and-slow operation
- Electric rates matter — at Rocky Mountain Power's residential tier, the math works; some out-of-state utilities won't
Homes already needing AC replacement, homes on tight building envelopes, customers who want to capture the wattsmart utility rebate and don't mind paying more upfront for lower operating cost.
Furnace
Gas combustion — proven, reliable, cheaper upfront
- Lowest install cost — typically half a heat pump
- Doesn't care how cold it gets — gas combustion is unaffected by outdoor temps
- Familiar — every Utah HVAC tech can diagnose one
- 20-year typical lifespan on a well-maintained 96% AFUE unit
- Single-purpose — you still need a separate AC
- Combustion appliance — requires venting, gas line, CO detector
- Operating cost can be higher than a heat pump on cheap-electricity utilities
- No wattsmart heat-pump rebate (those go to heat pumps) — though Enbridge ThermWise rebates can apply to high-efficiency gas equipment
Homes with an existing gas line, customers on tight budgets, replacing in winter when AC isn't on the priority list, or backup heat for a dual-fuel system.
Our Recommendation
For most Utah homes we install today: a heat pump as the primary, with a 96% AFUE gas furnace as the backup (a 'dual-fuel' system). You get heat pump efficiency above 20°F (which is most of the heating season here), the furnace takes over on the 5°F nights, and you collect the Rocky Mountain Power wattsmart rebate on the heat pump portion. If budget is tight and AC isn't broken, a 96% AFUE furnace alone is still a great install — the math just doesn't favor it long-term.
Common Questions
Will a heat pump actually heat my Utah home in winter?▼
Yes — but you need a cold-climate (CCHP) model rated for low-ambient operation, not the entry-level units sold in Texas. We size for Utah's winter design temp (0°F at sea level, lower in Wasatch/Summit County) and pair with backup heat for sub-15°F nights. A modern Mitsubishi Hyper Heat or Carrier Infinity Variable-Speed will heat down to -15°F without resistance heat.
Are there still rebates for heat pumps in Utah?▼
Yes — the federal 25C tax credit ended December 31, 2025, but Utah UTILITY rebates are very much alive. Rocky Mountain Power's wattsmart program (refreshed February 2026) pays up to $2,000 on qualifying heat pump installs in existing homes, and Enbridge Gas Utah's ThermWise program covers high-efficiency gas equipment and smart thermostats. We confirm the current amounts and file the rebate paperwork as part of every install.
Can I just convert my existing AC + furnace setup?▼
Not 1:1 — heat pumps need a matched indoor coil and a thermostat that knows how to manage refrigerant-cycle heating. If your AC is past 12 years and your furnace is past 15, the replacement window is the right time to switch. If only one is dying, dual-fuel is the better path.

There's a defensible line between 'just fix the capacitor' and 'this unit is done.' Three rules cover almost every Utah AC over 10 years old.
Tankless is more efficient and lasts longer, but only if the install is done right. Here's how the math actually plays out in Utah.
Three different problems, three different fixes. Most Utah homes need at least two of them — here's how to know which.
Trane and Lennox both make excellent equipment. The right pick depends on what you value — long-term parts availability, top-tier efficiency, or proven cold-climate performance.
Three different price points, three different priorities. Goodman wins on budget. Carrier wins on the resale story. Daikin's inverter tech is the efficiency leader.
A 96% furnace burns gas 16% more efficiently than an 80% — but the install is more involved (PVC venting, condensate drain). Does the upgrade actually pay back?
