Is the price difference a dealbreaker?
A 12% gap is meaningful on a project this size — about $650. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Indianapolis.

Furnace replacement by home size: Apex vs Indianapolis
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 | Apex | Indianapolis |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,000–$5,350 | $3,350–$6,000 |
| 1,500 sq ft (≈68,000 BTU) | $3,500–$6,150 | $3,900–$6,900 |
| 2,000 sq ft (≈90,000 BTU) | $4,000–$7,150 | $4,450–$8,050 |
| 2,500 sq ft (≈110,000 BTU) | $4,550–$8,150 | $5,150–$9,150 |
| 3,000 sq ft (≈130,000 BTU) | $5,150–$9,100 | $5,800–$10,300 |
| 3,500+ sq ft (≈150,000 BTU) | $5,750–$10,100 | $6,450–$11,400 |

What hvac pros earn in each metro
Since labor accounts for around 60% of what a furnace replacement job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

Cheapest time for furnace replacement in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
