Quick answer
Heat pumps cost $4,500-$11,000 installed; gas furnaces $3,200-$7,800. Heat pumps win on 10-year operating cost (20-30% lower energy bills) and qualify for SCE and RPU rebates of $300-$1,500. Gas furnaces win on upfront cost. For homes replacing both an aging AC and an aging furnace at once, the heat pump math usually wins.
The cost question between heat pumps and gas furnaces is not just the install price — it is the 10-year total of upfront install plus monthly energy bills minus rebates. For most homes across our service area (Hesperia and the wider High Desert plus our Inland Empire cities) with both an aging AC and an aging furnace, replacing both with one heat pump beats replacing them separately. For homes where only the furnace is at end of life, the math is more nuanced. This guide lays out both paths with real numbers from current local invoices and current SCE / RPU / SoCalGas rebate sheets.
What it costs
Real numbers, not estimates.
| Range | Tier | What it covers |
|---|---|---|
| $3,200-$7,800 | Gas/propane furnace install | Replaces furnace only. AC stays separate. SoCalGas rebates on 95%+ AFUE. |
| $4,500-$11,000 | Heat pump install | Replaces both AC and furnace. SCE rebates $300-$1,500. |
| $2,500-$5,500 | AC replacement only | Standard SEER2 14-16, used when furnace stays. |
| $8,500-$13,000 | Dual-fuel system | Heat pump + backup gas/propane furnace. Belt-and-suspenders winter reliability. |
Heat pump install includes both heating and cooling capability. Furnace install does not include AC. For full system replacement on aging-AC + aging-furnace homes, heat pump is the cost-effective consolidation play.
What drives the price up
Why your quote might be higher.
-
Heat pump variable-speed inverter equipment
Cold-climate variable-speed heat pumps (Mitsubishi Hyper-Heat, Daikin Aurora, Carrier Infinity) cost $1,500-$3,000 more than standard SEER2 14 heat pumps but maintain capacity at sub-30°F temperatures and last longer.
-
Electrical panel upgrade
Heat pumps require dedicated 240V circuits and pull more amps than gas furnaces. Older 100A panels often need upgrading to 200A, adding $1,500-$3,000 to heat pump installs. Most newer (post-2010) HD homes already have 200A.
-
Premium 96% AFUE furnace tier
On the furnace side, jumping from 80% AFUE to 96% AFUE adds $3,000-$4,500 and shifts the comparison math toward heat pump.
What drives the price down
How to save money.
-
SCE rebates on heat pumps
Southern California Edison runs ongoing rebates of $300-$1,500 on qualifying heat pumps. Tier depends on equipment type and SEER2 rating. Pulls heat pump install cost closer to gas furnace cost in real dollars.
-
Heat pump consolidation savings
When both AC and furnace are at end of life, replacing both with one heat pump avoids two separate installs over 10-15 years. Saves $3,000-$5,000 in total replacement cost.
-
20-30% lower monthly energy bills with heat pump
Heat pumps run 200-400% efficient (HSPF 8-10) vs. 80-96% for gas furnaces. Total monthly energy cost (electric + gas combined) typically drops 20-30% with heat pump conversion. Pays back $3,000-$5,000 over 10 years for most HD homes.
Rebates that apply in 2026
Real rebates.
SCE heat pump rebates: $300-$1,500 depending on SEER2 tier and unit type. Active for 2026, no expiration announced. SoCalGas furnace rebates: $200-$800 on 95%+ AFUE. Federal IRA 25C / 25D tax credits expired December 31, 2025 (these used to add $2,000+ for heat pump installs). Manufacturer rebates seasonally available. We pull current rebate sheets at quote time.
Honest take from the owner
Joey's straight answer.
Joey's honest read: for most High Desert tract homes built 1995-2010 with aging R-22 AC + 80% AFUE gas furnace both nearing end of life, heat pump conversion is the smart long-term move. SCE rebates close the upfront cost gap, and 10-year monthly bill savings deliver real dollars. For homes where only the furnace is at end of life and the AC has 5+ years left, replacing the furnace is usually cheaper short-term but locks in two separate replacement cycles. Dual-fuel systems (heat pump + backup gas furnace) are the third option for homeowners who want belt-and-suspenders winter reliability without giving up heat pump efficiency. We will run all three scenarios at quote time using your actual past 12 months of bills.
