Quick answer
Furnace replacement typically runs $3,200 to $7,800 installed in 2026. 80% AFUE entry-tier units $3,200-$4,800; 90-95% AFUE high-efficiency $4,800-$6,200; 96% AFUE premium modulating $6,200-$7,800. SoCalGas rebates apply to 95%+ AFUE installs. Propane installs (HD higher-elevation homes) add $500-$1,500.
Furnace replacement pricing across our service area — Hesperia, Apple Valley, Victorville and the wider High Desert plus Riverside, San Bernardino, Rancho Cucamonga, Jurupa Valley, and Rialto in the Inland Empire — lands within national HomeGuide ranges of $3,200-$7,800 installed in 2026. Final price depends on AFUE efficiency tier (higher AFUE = lower monthly bills but higher upfront), BTU output (sized to your home via Manual J load calculation), ductwork condition (replacements may need return-air resizing), and gas line work (propane installs in the higher-elevation HD areas run a slight premium). Permits are pulled and final inspection coordinated as part of every install.
What it costs
Real numbers, not estimates.
| Range | Tier | What it covers |
|---|---|---|
| $3,200-$4,800 | 80% AFUE standard | 60-80k BTU, single stage, base efficiency. No SoCalGas rebate. |
| $4,800-$6,200 | 90-95% AFUE high-eff | 80-100k BTU, two-stage, variable blower. SoCalGas rebate eligible. |
| $6,200-$7,800 | 96% AFUE premium | 100-120k BTU, modulating, smart controls. Highest rebate tier. |
| +$500-$1,500 | Propane premium | Phelan, Wrightwood propane installs (orifice + regulator work). |
| +$1,000-$3,000 | Ductwork upgrade | Return-air resizing or full duct replacement when needed. |
Range based on actual JC Energy Solutions install invoices. SoCalGas natural gas rebates can offset $200-$800 on 95%+ AFUE installs.
What drives the price up
Why your quote might be higher.
-
Higher AFUE efficiency tier
80% AFUE is the entry baseline. 90-95% AFUE adds $1,000-$1,500. 96% AFUE modulating adds another $1,500-$2,000. Higher tiers pay back via lower gas bills over 15-20 year furnace lifespan.
-
Propane vs. natural gas
Propane requires propane-rated equipment, different orifice sizing, and regulator work. Adds $500-$1,500 to install cost vs. natural gas equivalent. Affects Phelan, Wrightwood, parts of Oak Hills, and Lucerne Valley installs.
-
Ductwork condition
Older HD homes often have undersized return ducts that strangle modern variable-speed blowers. Return-air resizing adds $1,000-$3,000. Full duct replacement runs $25-$55 per linear ft.
-
Larger BTU output
Bigger homes (3,000+ sq ft) need 100-120k BTU furnaces vs. 60-80k for tract homes. Bigger units cost 15-25% more in equipment alone, plus larger gas line and venting.
What drives the price down
How to save money.
-
SoCalGas rebates on 95%+ AFUE
SoCalGas runs ongoing rebates of $200-$800 on qualifying high-efficiency natural gas furnaces. We pull current rebate sheets at quote time and apply automatically.
-
Like-for-like swap
When existing ductwork, gas line, and electrical are already sized correctly for the new furnace, install time drops to one day. No rebate-chasing or system upsizing complications.
-
Off-season scheduling
Spring and early summer (April-June) are the cheapest months to replace a furnace. Fall and winter have higher demand and fuller schedules.
Rebates that apply in 2026
Real rebates.
SoCalGas runs ongoing rebates of $200-$800 on qualifying 95%+ AFUE high-efficiency natural gas furnaces. Federal IRA 25C tax credits expired December 31, 2025 and no longer apply. Manufacturer rebates (Carrier Cool Cash, Trane, Lennox) appear seasonally with $200-$1,000 instant savings. We pull every applicable rebate at quote time and apply to your final price. SCE electric rebates apply to heat pump installs but not gas furnace installs.
Honest take from the owner
Joey's straight answer.
Joey's honest take: most High Desert homes do not need a 96% AFUE premium furnace. The payback period on the highest-efficiency tier rarely beats 8-10 years vs. mid-tier 90% AFUE. For most Hesperia, Apple Valley, and Victorville tract homes, 90-95% AFUE is the right balance of upfront cost, monthly bill savings, and rebate capture. Premium 96% modulating units make sense for larger custom homes (3,000+ sq ft) where heating is a year-round dominant cost. We will lay out the payback math at quote time using your actual past 12 months of gas bills.
