What hvac pros earn in each metro
Since labor accounts for around 60% of what a furnace replacement job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

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 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 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
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
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.
