Cheapest time for furnace replacement in either city
A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
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 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
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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.

Do hvac pros really charge more in one city?
It's not a myth — BLS data puts installer wages at about $33/hr in the Indianapolis-Carmel-Greenwood area and $36.7/hr in Minneapolis-St. Paul-Bloomington. Given labor is around 60% of a furnace replacement job's cost, that gap explains most of the price spread.

Should I choose where to live based on furnace replacement cost?
Not really — the $450 gap is one-time, and smart timing and tighter quotes in Plymouth can shrink it. Factors that compound over time, like energy prices and home condition, deserve more weight than a single upfront difference.
