AC replacement cost calculator
Data last verified July 24, 2026· cost data
An estimate range, not a quote. Base ranges are national 2026 figures, adjusted by SEER2 tier and state labor costs. Published sources disagree by 40–50% at the same tonnage — which is why this is a range and why anyone giving you a single number is guessing. How we estimate.
Assumptions: national base ranges per tonnage (2026, synthesis of 9 sources, confidence: estimate); efficiency multipliers ×1.15 (16–17 SEER2) and ×1.35 (18+); state adjustment = BLS HVAC-trade wage index. Straight-cool split system, existing compatible ductwork, no electrical upgrades.
