How this number is built
We start from a 2026 national baseline for HVAC replacement and apply a Michigan cost factor of 0.98, which reflects local labour, permitting and material costs. That puts Michigan 2% below the national average — ranked #29 of 51 from cheapest to most expensive.
That covers a full replacement — typically a 3–4 ton heat pump or AC-and-furnace pairing — installed and hauled away, before utility rebates. In Michigan, where electricity is 19.2¢/kWh, efficiency rating changes running cost more than most people expect.
What moves the price
- System size (tonnage) for your square footage
- Efficiency rating (SEER2)
- Ductwork condition and any modifications
- Heat pump vs traditional AC and furnace
