How this number is built
We start from a 2026 national baseline for HVAC replacement and apply a New Mexico cost factor of 0.90, which reflects local labour, permitting and material costs. That puts New Mexico 10% below the national average — ranked #9 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 New Mexico, where electricity is 14.5¢/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
