Mini-Split Cost and Rebates in Massachusetts (2026)
Figures checked November 10, 2026. Rebate amounts are from masssave.com; price ranges are from 2026 Massachusetts installer guides.
Short answer: a single-zone ductless mini-split in Massachusetts typically costs about $4,000 to $14,000 installed, and a multi-zone system for most of a home about $9,000 to $25,000, before rebates. Mass Save pays $1,125 per ton if you keep your boiler or furnace, or $2,650 per ton if heat pumps become your only heat, up to $8,500 in 2026. Those rebates drop on January 1, 2027.
Mini-split cost in Massachusetts (2026)
| Project | Typical installed cost, before rebates |
|---|---|
| Single zone (one indoor unit) | About $4,000-$9,000 (MassHVAC) to $6,000-$14,000 (Endless Energy) |
| Multi-zone (several rooms or the whole home) | About $9,000-$24,000 (Endless Energy) to $12,000-$25,000 (MassHVAC) |
The spread is wide because no two homes are alike, and installer estimates vary. Compare quotes for the same equipment and number of zones.
What changes the price
- Number of zones: each indoor head adds equipment and labor.
- Line-set runs: the distance and route between the outdoor unit and each indoor unit.
- Cold-climate equipment: units rated to heat through Massachusetts winters cost more, and rebates require models on Mass Save’s Qualified Products List.
- Electrical work: a new circuit, and sometimes a panel upgrade in older homes.
- Indoor unit style: wall-mounted heads cost least; ceiling cassettes and concealed ducted units cost more.
Mass Save mini-split rebates in 2026
| Your situation | Rebate type | 2026 amount |
|---|---|---|
| Keep your boiler or furnace as backup | Partial-Home | $1,125 per ton, up to $8,500, plus possible $500 weatherization and $500 sizing bonuses |
| Mini-splits become your only heating and cooling | Whole-Home | $2,650 per ton, up to $8,500 |
| Not replacing oil, propane, gas or electric resistance heat | Basic | $250 per ton, up to $2,500 |
| Income-qualified home heating with oil, propane or electric resistance | Income-based enhanced | Up to $16,000, or up to no cost through Turnkey Services |
Tons are the unit’s rated cooling capacity divided by 12,000 BTU, so a 12,000 BTU wall unit counts as 1 ton. You also need a Mass Save Heat Pump Installer Network contractor; Nexis Power is one.
Two examples
- Two rooms, keeping the boiler: two 1-ton units = 2 x $1,125 = $2,250 partial-home rebate, plus up to $1,000 in bonuses if you qualify.
- Whole home, boiler removed: four zones totaling 3.5 tons = 3.5 x $2,650 = $9,275, capped at $8,500.
These are illustrations; your rebate depends on the exact equipment and the program rules. Check yours with our Mass Save heat pump rebate calculator.

Is a mini-split right for your home?
Mini-splits are ideal for homes with radiators or baseboard heat, additions, finished basements, and rooms that are always too hot or too cold. If your home already has good ductwork, a ducted heat pump may cost less per room. Compare both on our ductless mini-split installation page, or see whole-project numbers in heat pump installation cost in Massachusetts.
