What's New in 2026 That Affects Cost

R-454B Refrigerant Mandate

As of January 2025, the EPA requires newly manufactured residential AC equipment to use low-GWP refrigerants like R-454B or R-32 instead of R-410A. However, existing R-410A equipment that was manufactured before the cutoff can still be legally sold and installed. In practice, most new systems you'll see quoted in 2026 use R-454B, but R-410A units may still be available from existing stock. The new refrigerant is similarly priced, though newly certified R-454B equipment may cost slightly more as manufacturers continue updating 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

1. Get 3+ quotes — Prices can vary 30-50% between contractors for the same equipment.
2. Buy in the off-season — Spring and fall installations often come with lower labor costs and manufacturer rebates.
3. Check utility rebates — Your electric company may offer $200–$1,000+ for high-efficiency systems.
4. Don't oversize — An oversized unit costs more to buy and more to run. Use our AC sizing calculator to find the right size.
5. Consider a heat pump — In moderate climates, a heat pump handles both heating and cooling, potentially replacing two systems with one.
6. Ask about financing — Many contractors offer 0% APR financing for 12–60 months.
