What Efficiency Vermont pays in 2026
Most amounts are instant discounts taken at purchase through a participating contractor or retailer.
Ductless heat pump
$375 for up to 2 tons and $475 over 2 tons, effective January 1, 2026. Integrated controls add up to $600. Ducted systems pay $1,200 up to 2 tons, $1,700 over 2 and under 4 tons and $2,200 at 4 tons or more.
Income bonus on heat pumps
Green Mountain Power low-income customers receive $2,200, VPPSA municipal utility customers $1,000 and all others $200. Rental owners and Burlington Electric customers are not eligible for this bonus.
Heat pump water heater
$400 more for income-eligible households. Effective August 16, 2025.
Home Performance with ENERGY STAR
Covers 75% of insulation and air-sealing cost. Needs a participating contractor and at least a 10% blower-door improvement. Effective July 1, 2026, while funding lasts.
Ground-source heat pump
Plus $500 for income-eligible Vermonters. New systems up to 10 tons.
Thermostats and appliances
Smart thermostat up to $100, dryers up to $400, window air conditioners $150, wood or pellet stoves $400 and dehumidifiers from $25.
Burlington Electric and Vermont Gas customers are paid by their own utility for weatherization, up to $9,500 for a single-family home.
Why the weatherization figure fell
The January 2026 announcement quoted weatherization rebates of up to $4,000 and $9,500. Efficiency Vermont's page now lists $3,000 and $7,000 for offers effective July 1, 2026. The $9,500 figure survives only for Burlington Electric and Vermont Gas customers. We use the page, not the announcement, because the page is what a contractor submits against. If a contractor quotes $9,500 and you are a Green Mountain Power customer, ask for the program page to be shown.
How your utility changes the number
The same heat pump earns a different total depending on who sends your electric bill. A Green Mountain Power low-income customer collects the $2,200 bonus. A customer of a VPPSA municipal utility gets $1,000 at moderate or low income, and everyone else gets $200. Burlington Electric customers sit outside the bonus and instead use Burlington Electric's own post-purchase rebates of up to $2,900 on ductless and $8,750 on ducted systems.
Other utilities add smaller offers: Stowe Electric $250, Vermont Electric Co-op $150, and VPPSA municipalities $200 on weatherization and water heaters.
Ducted or ductless
Ductless mini-splits are cheaper and simpler in a home with no ductwork. Ducted systems pay more because they serve the whole house. Size drives the ducted amount, so a large home with a 4-ton system reaches $2,200 while a 2-ton system gets $1,200. Ask for a load calculation before choosing tonnage.
Financing the rest
Efficiency Vermont lists a Home Energy Loan with rates starting at 0% interest, and free products for income-qualified Vermonters. Weatherization first can reduce the heat pump size you need.
