What hvac pros earn in each metro
About 60% of a furnace replacement bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

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?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
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.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
