What's New in 2026 That Affects Cost
R-454B Refrigerant Mandate
Starting January 2026, all new AC installations must use low-GWP refrigerants like R-454B or R-32 instead of R-410A. The new refrigerant itself is similarly priced, but the transition means slightly higher costs for newly certified equipment as manufacturers update their product lines.
Federal Tax Credit Expiration
The Section 25C federal tax credit expired December 31, 2025. This means the $600 credit for central ACs and $2,000 credit for heat pumps are no longer available for new installations. Read our full tax credit guide for details on what may still be available.
6 Ways to Save on AC Replacement
- Get 3+ quotes — Prices can vary 30-50% between contractors for the same equipment.
- Buy in the off-season — Spring and fall installations often come with lower labor costs and manufacturer rebates.
- Check utility rebates — Your electric company may offer $200–$1,000+ for high-efficiency systems.
- Don't oversize — An oversized unit costs more to buy and more to run. Use our AC sizing calculator to find the right size.
- Consider a heat pump — In moderate climates, a heat pump handles both heating and cooling, potentially replacing two systems with one.
- Ask about financing — Many contractors offer 0% APR financing for 12–60 months.
