New York Permits, Efficiency Rules and Rebates
New York falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Expect the contractor to pull a mechanical permit for a replacement job in Mount Vernon. If a bidder suggests skipping it, move on. Also ask for a New York license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
