Is the price difference a dealbreaker?
A 10% gap is meaningful on a project this size — about $550. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Indianapolis.

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
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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.
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 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.
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.
