Vermont Permits, Efficiency Rules and Rebates
Vermont 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 Essex Junction. If a bidder suggests skipping it, move on. Also ask for a Vermont 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 your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
