HVAC costs by state: where homeowners pay the most
A typical 2026 HVAC install — averaging a furnace replacement and central AC — runs about $7,100 nationally. But state by state the bill swings hard: Hawaii tops the list at roughly $8,150 (+15%), while North Dakota is the most affordable at about $6,800 (-4%).
What the data shows
- The most expensive state for HVAC work in 2026 is Hawaii, at about $8,150 for a typical furnace-plus-AC project.
- The most affordable is North Dakota at roughly $6,800 — a 20% gap between the two.
- Figures are population-weighted across each state's cities, so they reflect where people actually live, not just one metro.
- High-cost states are driven by elevated local labor rates; climate plays a secondary role since furnace and AC costs partly offset between cold and hot zones.

How we calculated this
Figures are localized 2026 planning estimates — not quotes. We start from researched national price ranges, then adjust each location for local labor rates (U.S. Bureau of Economic Analysis Regional Price Parities), climate zone (IECC) and typical permit fees. Full method on our methodology page.
