Furnace replacement by home size: Indianapolis vs Sunnyvale
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 | Sunnyvale |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,350–$6,000 | $3,750–$6,750 |
| 1,500 sq ft (≈68,000 BTU) | $3,900–$6,900 | $4,350–$7,700 |
| 2,000 sq ft (≈90,000 BTU) | $4,450–$8,050 | $5,000–$8,950 |
| 2,500 sq ft (≈110,000 BTU) | $5,150–$9,150 | $5,750–$10,200 |
| 3,000 sq ft (≈130,000 BTU) | $5,800–$10,300 | $6,500–$11,450 |
| 3,500+ sq ft (≈150,000 BTU) | $6,450–$11,400 | $7,200–$12,700 |

What hvac pros earn in each metro
Labor is about 60% of a furnace replacement bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

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?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
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 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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.
