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 customers can get rebates on 92%+ AFUE installs through Dec 31, 2026 or until funds run out. 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 utility rebate. |
| $4,800-$6,200 | 90-95% AFUE high-eff | 80-100k BTU, two-stage, variable blower. SoCalGas rebate eligible (92%+). |
| $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). |
| + | Ductwork upgrade | Return-air resizing or full duct replacement when needed. |
Range based on actual JC Energy Solutions install invoices. For SoCalGas customers, 2026 rebates can offset part of the cost on 92%+ AFUE installs. Southwest Gas customers (most of the Victor Valley) should expect no utility furnace rebate unless a new program opens.
Altitude sizing
Furnace cost at elevation.
A gas furnace loses about 4% of its rated output for every 1,000 ft above 2,000 ft (NFPA 54). That changes the furnace you should buy in the High Desert: a unit sized by a sea-level rule of thumb comes up short on the coldest nights, and one oversized to compensate short-cycles and wears out the heat exchanger. We size every High Desert install with a Manual J load calculation and then apply the derate for your elevation. The full altitude guide has the math. Inland Empire cities sit under about 1,200 ft and need no correction.
| City (elevation) | Output derate | What it means for your quote |
|---|---|---|
| Victorville (2,700 ft) | 2.8% | Minor correction. Usually the same size class as a sea-level install. |
| Apple Valley (2,900 ft) | 3.6% | Minor correction. Manual J decides whether to step up. |
| Hesperia (3,200 ft) | 4.8% | Borderline homes often move up one BTU step. |
| Phelan (3,800 ft) | 7.2% | Plan for the next BTU step on most homes. Many are propane. |
| Oak Hills (4,200 ft) | 8.8% | Next BTU step is typical. Propane common in parts of Oak Hills. |
| Wrightwood (6,000 ft) | 16% | Largest correction in our area. Propane plus high-altitude equipment settings. |
Gas vs electric
Furnace vs heat pump replacement cost.
When the furnace dies and the AC is also near the end, the real question is gas furnace or heat pump. A gas furnace replacement is the lower upfront number. A heat pump replaces both heating and cooling in one system, which narrows the gap when both are near the end. Dual-fuel pairs a heat pump with a gas or propane furnace for the coldest nights, which is the setup we recommend for Wrightwood and high-elevation Phelan. See the heat pump vs furnace cost comparison for the operating-cost side.
| System | Typical installed cost | Best fit |
|---|---|---|
| Gas furnace only | $3,200-$7,800 | Heating only. Keeps your existing AC. Gas utility rebates on 92%+ AFUE where offered. |
| Standard ducted heat pump | $4,500-$11,000 | Heating and cooling in one system. Rebates checked at quote time. |
| Cold-climate heat pump | $6,500-$13,000 | Phelan, Oak Hills, Wrightwood. Holds capacity below 30°F. |
| Dual-fuel add-on | +$3,000-$5,000 | Gas or propane backup over a standalone heat pump. Wrightwood default. |
Repair or replace
When to replace instead of repair.
Most gas furnaces last 15 to 20 years. Replacement makes sense when a combustion test finds a cracked heat exchanger (it can leak carbon monoxide into the supply air and is not a safe repair), when the furnace is past 15 years and needs a major part like a gas valve or inducer motor, or when repairs are coming every season. Short of that, a repair is usually the better money. We give you both numbers on the same visit. Start with furnace repair or a fall tune-up if you are not sure where your furnace stands.
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. 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.

Gas utility rebates on high-efficiency furnaces
Gas utility rebates depend on who supplies your gas. SoCalGas (most of the Inland Empire) pays 2026 rebates on 92%+ AFUE furnaces, scaled to the furnace size, through Dec 31, 2026 or until funds run out. Most Victor Valley homes (Hesperia, Victorville, Apple Valley, Adelanto) are on Southwest Gas, whose California furnace rebate program ended in 2025, so we check at quote time whether a new one has opened.
-
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.
Gas utility rebates depend on who supplies your gas. SoCalGas (most of the Inland Empire) pays 2026 rebates on 92%+ AFUE furnaces, scaled to the furnace size, through Dec 31, 2026 or until funds run out. Most Victor Valley homes (Hesperia, Victorville, Apple Valley, Adelanto) are on Southwest Gas, whose California furnace rebate program ended in 2025, so we check at quote time whether a new one has opened. Federal IRA 25C tax credits expired December 31, 2025 and no longer apply. Manufacturer rebates (Carrier Cool Cash, Trane, Lennox) appear seasonally as 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.
