How much should this gap actually matter?
A 17% gap is meaningful on a project this size — about $900. 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

Cheapest time for furnace replacement in either city
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
How much should you really budget for HVAC in 2026?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
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.
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 brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
