Heat pump installation
Right-sized cold-climate heat pumps. Mass Save rebates filed for you.
Mitsubishi Hyper-Heat and Carrier Infinity cold-climate systems sized with a real Manual J load calculation — not a rule of thumb. Mass Save rebates typically take $5,000 to $10,000 off the price; we file the paperwork. Most installs land 2–4 weeks from a signed quote and finish in one to two days on-site.
Pricing
What it costs.
Heat pump prices reflect the equipment, install labor, electrical, and code-required permits — before Mass Save rebates. We file rebate paperwork for you and net it out of the final invoice.
-
Single-zone ductless mini-split
One outdoor unit, one indoor head. Mitsubishi or Carrier cold-climate (rated to -5°F). Typical for a finished basement, sunroom, or single-room addition.
$4,500–$6,500 -
Two- to three-zone ductless system
One outdoor unit, two or three indoor heads on the same refrigerant loop. Common for whole-floor or two-floor partial-coverage installs.
$9,000–$15,000 -
Whole-home ducted heat pump (2–3 ton)
Air-handler replacement for an existing ducted system, paired with a new outdoor cold-climate heat pump. Typical 1,500–2,500 sq ft MetroWest home.
$14,000–$20,000 -
Whole-home ducted heat pump (4–5 ton)
Two-story 2,500–4,000 sq ft home, often with two-stage or modulating equipment. Includes duct modifications if needed.
$20,000–$28,000 -
Hybrid: heat pump + existing gas furnace
Adds an outdoor heat pump to an existing 90%+ gas furnace, with a smart thermostat that switches between them on price-per-BTU. Best of both fuels.
$8,000–$13,000 -
Manual J load calculation
Done on every install — sizing the system based on your actual home, not its square footage. Included free with a signed install. Available standalone for second opinions.
$350
Mass Save residential heat pump rebates run $5,000–$10,000 on most whole-home installs (whole-home electrification rebate is $10,000 for income-eligible households, $6,000 for everyone else, plus $1,250/ton on hybrid installs). The Inflation Reduction Act federal tax credit adds up to $2,000 on top. We file all rebate paperwork; the credit shows on your tax return the following April. Wisetack financing: 12, 24, 36, or 60 months with no prepayment penalty.
How it goes
From the call to a finished install.
-
Site visit and Manual J
Mike or a senior tech walks the house — measures, looks at insulation, checks the electrical panel, runs a Manual J load calculation. About 90 minutes.
-
Quote with rebate math
Written quote in 2–3 business days. Equipment options, install labor, electrical, permits, and your Mass Save rebate — gross price and net price, both on the page.
-
Permits, scheduling, equipment
We pull the gas, building, and electrical permits, order the equipment, and schedule the install — typically 2–4 weeks out depending on the season.
-
Install, commission, file the rebate
One to two days on-site. Full commissioning per Mitsubishi/Carrier spec, inspection scheduled. We submit your Mass Save paperwork the day after the install.

Questions
Worth asking before you book.
Do heat pumps actually work in a Massachusetts winter?
The cold-climate models we install are rated to provide their full heat output down to 5°F and continue working (at reduced capacity) to -5°F. We've installed Mitsubishi Hyper-Heats that have run through every winter since 2018 in Framingham without backup heat. The math has changed — heat pumps that struggled in 2010 are not the equipment we're putting in today.
Mitsubishi or Carrier?
Both are excellent. Mitsubishi Hyper-Heat has the longest cold-climate track record and slightly better -5°F performance; we install more of them. Carrier Infinity is closer behind every year and the ducted equipment integrates better with existing duct systems. We'll recommend per your home and the math, not per a sales spiff.
How big should my system be?
The right answer comes from a Manual J load calculation, not a rule of thumb. Most MetroWest homes we look at have existing furnaces that are 30–50% oversized — sizing a new heat pump to match would cycle hard and run inefficient. We size to the actual heat loss of your home.
Do I need to upgrade my electrical panel?
Sometimes. A whole-home heat pump typically needs a dedicated 30- or 50-amp circuit. If your panel is 100 amps with no spare slots, you may need a panel upgrade — a separate $2,000–$4,000 line item we'll flag in the quote. About one in four installs we do needs panel work.
How long does the install take?
One day for a single-zone ductless, one to two days for a multi-zone or ducted system, two to three days if duct modifications are involved. Equipment lead times run 2–4 weeks most of the year, longer in early fall when everyone's racing to spend rebate dollars before year-end.
What does Mass Save actually cover?
For most whole-home electrification projects: $10,000 if your household is income-eligible (under 80% area median income), $6,000 otherwise. For hybrid installs that keep a backup furnace: $1,250 per ton, max $10,000. Plus 0% interest financing on the unrebated portion for up to seven years if you want it (most customers go with Wisetack instead — faster paperwork).
Will my heating bill actually go down?
Almost always — but the size of the swing depends on what you're replacing. Going from electric resistance: enormous savings, often 60–70%. From oil: typically 30–45% savings at current oil prices. From gas: usually 5–15% savings on new high-efficiency cold-climate equipment. The IRA tax credit and Mass Save rebate are doing more of the financial heavy lifting than the operating-cost difference for gas-to-heat-pump customers right now.
