How much should this gap actually matter?
A 9% spread (roughly $500) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Indianapolis typically recover some of it.

Furnace replacement by home size: Indianapolis vs Oshkosh
Furnace cost scales with the heating capacity (BTU) your home needs — roughly 40–45 BTU per square foot in a mixed climate. Larger homes need a bigger unit and more ductwork.
| Size | Indianapolis | Oshkosh |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,350–$6,000 | $3,050–$5,500 |
| 1,500 sq ft (≈68,000 BTU) | $3,900–$6,900 | $3,550–$6,350 |
| 2,000 sq ft (≈90,000 BTU) | $4,450–$8,050 | $4,100–$7,350 |
| 2,500 sq ft (≈110,000 BTU) | $5,150–$9,150 | $4,700–$8,350 |
| 3,000 sq ft (≈130,000 BTU) | $5,800–$10,300 | $5,300–$9,400 |
| 3,500+ sq ft (≈150,000 BTU) | $6,450–$11,400 | $5,900–$10,400 |

What hvac pros earn in each metro
Roughly 60% of what you pay for furnace replacement is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for furnace replacement in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
