Mass Save Qualified Heat Pumps 2026
Complete QPL guide with interactive model checker. All 12 NuWatt brands verified. HPIN-certified installation for guaranteed rebate eligibility.
Quick Answer: What Heat Pumps Qualify for Mass Save?
Mass Save qualifies heat pumps that meet ENERGY STAR 6.1 Cold-Climate specifications: HSPF2 ≥ 8.5, SEER2 ≥ 15.2, HCR ≥ 70% at 5°F, and COP ≥ 1.75 at 5°F for ductless systems. All 12 brands NuWatt installs have qualifying models on the QPL as of February 2026. To receive the rebate, installation must be performed by an approved Heat Pump Installer Network (HPIN) contractor — NuWatt is an approved HPIN installer.
What Is the Mass Save Heat Pump Qualified Products List?
The Mass Save Qualified Products List (QPL) is a database of over 160,000 AHRI-certified outdoor and indoor unit combinations that meet Mass Save's efficiency requirements for heat pump rebates. Only systems on the QPL qualify for rebates — no exceptions.
The QPL is maintained by Mass Save and updated periodically as manufacturers certify new models and retire older ones. It uses AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certification data to verify that each specific outdoor unit + indoor unit combination meets the minimum performance thresholds.
As of 2026, the QPL exclusively lists heat pumps using R-32 or R-454B refrigerants. R-410A systems were removed from the QPL effective January 1, 2026, due to high global warming potential (GWP 2,088). Any heat pump using R-410A refrigerant receives $0 in Mass Save rebates regardless of its efficiency ratings.

HSPF2
Heating Seasonal Performance Factor 2 measures overall heating efficiency across an entire season. Higher HSPF2 = lower heating bills. Uses the DOE M1 test procedure. An HSPF2 of 10.0 is about 20% more efficient than the 8.5 minimum.
SEER2
Seasonal Energy Efficiency Ratio 2 measures cooling efficiency. Higher SEER2 = lower cooling bills in summer. The minimum 15.2 applies to all equipment types. Top models from KEEN and Fujitsu exceed SEER2 33.
HCR @ 5°F
Heating Capacity Ratio at 5°F measures what percentage of rated heating capacity the system maintains when outdoor temperature drops to 5°F. The 70% minimum ensures the heat pump can handle cold Massachusetts winters.
COP @ 5°F
Coefficient of Performance at 5°F measures instantaneous heating efficiency at 5°F. A COP of 1.75 means the heat pump produces 1.75 units of heat for every 1 unit of electricity consumed — still 75% more efficient than electric resistance heat.

Having a QPL-qualifying heat pump is only half the requirement for receiving Mass Save rebates. The installation must also be performed by a contractor in the Heat Pump Installer Network (HPIN). Without an HPIN-certified installer, you will receive $0 in rebates — even if your equipment is on the QPL.
The Heat Pump Installer Network (HPIN) is the Mass Save-approved network of contractors authorized to install heat pump systems that qualify for rebates. Even if a heat pump system is on the QPL, the homeowner will not receive the Mass Save rebate unless the installation is performed by an HPIN-certified contractor.
HPIN Requirements
- Licensed Massachusetts HVAC contractor
- Completed Mass Save HPIN training and certification
- Maintains proper insurance and bonding
- Submits rebate paperwork through Mass Save portal
- Performs Manual J load calculations for Whole-Home tier

Full rebate guide with calculatorIntegrated Controls Requirement for Dual-Fuel Setups
For dual-fuel installations where a heat pump works alongside an existing gas or oil furnace/boiler, Mass Save requires an approved Integrated Control (IC). The IC manages the switchover between heat pump and backup heating based on outdoor temperature or efficiency optimization. Without an approved IC, a dual-fuel setup will not qualify for Mass Save rebates.
An Integrated Control is only required for dual-fuel setups (heat pump + existing fossil fuel backup). Full heat pump replacements (no backup boiler/furnace) do not require an IC.
Approved Integrated Controllers
Carrier Infinity System Control(Thermostat)
Works with Carrier Greenspeed systems; manages heat pump + gas furnace switchover
Google Nest Thermostat (3rd Gen+)(Smart Thermostat)
Compatible with most brands; uses outdoor temperature for switchover
Cielo Breeze Plus / Pro(Smart Controller)
Infrared controller for ductless mini-splits; manages setpoints and scheduling
Flair Puck Pro(Smart Controller)

How to Verify Your System on the Official QPL
While NuWatt handles QPL verification as part of every project, you can independently verify any heat pump system on the official Mass Save QPL. Here is a step-by-step guide.
Visit the Official QPL Page
Go to masssave.com/heat-pump-qualified-list. The QPL is available as a downloadable Excel spreadsheet and an online search tool.
Search by AHRI Number (Most Reliable)
Every certified outdoor+indoor combination has a unique AHRI certificate number. Ask your installer for this number and search it directly. This is the most accurate method.
Search by Outdoor Model Number
If you do not have the AHRI number, search by the outdoor unit model number. Note that model numbers on the QPL include full suffixes — a partial match may not return results.
Verify Equipment Type and Efficiency
Confirm the entry matches your installation type (ductless, ducted mini-split, ducted central, or high velocity) and that all efficiency metrics meet the minimums for that type.
Confirm Refrigerant Type
The entry should show R-32 or R-454B refrigerant. Any entry showing R-410A is from an outdated version of the QPL and no longer qualifies for rebates.
Frequently Asked Questions
What heat pumps qualify for Mass Save rebates?
Heat pumps must appear on the Mass Save Qualified Products List (QPL) to be eligible for rebates. The QPL requires ENERGY STAR 6.1 Cold-Climate certification. For ductless mini-splits, minimums are HSPF2 8.5, SEER2 15.2, HCR 70% at 5°F, and COP 1.75 at 5°F. For ducted central systems, the minimum is SEER2 15.2. All 12 brands that NuWatt installs have qualifying models on the QPL as of February 2026.
Does my heat pump need to be on the QPL?
Yes. The heat pump system (outdoor unit + indoor unit combination) must be on the Mass Save Qualified Products List to receive any rebate. Mass Save verifies the specific AHRI-certified combination, not just the brand or model series. The QPL contains over 160,000 AHRI-certified outdoor+indoor unit combinations that meet the efficiency requirements.
How do I check if my heat pump is on the Mass Save QPL?
Visit masssave.com/heat-pump-qualified-list to search the official QPL. The most reliable way to check is by AHRI certificate number, which your installer should provide. You can also search by outdoor unit model number or manufacturer. NuWatt provides QPL verification as part of every project proposal.
What is HSPF2 and why does it matter for Mass Save?
HSPF2 (Heating Seasonal Performance Factor 2) measures heating efficiency over an entire season using the updated DOE M1 test procedure. Higher HSPF2 means more heat output per unit of electricity consumed. Mass Save requires a minimum HSPF2 of 8.5 for ductless mini-splits and 8.1 for ducted mini-splits to ensure the heat pump performs efficiently in Massachusetts winters. A heat pump with HSPF2 10+ will deliver lower heating bills than one at the 8.5 minimum.
Does Mitsubishi qualify for Mass Save rebates?
Yes. Mitsubishi has 198 AHRI-certified combinations on the Mass Save QPL, including 85 outdoor models. The Hyper-Heat H2i and M-Series multi-zone systems qualify for ductless mini-split rebates with best-in-class HSPF2 ratings up to 12.0. Mitsubishi does not currently have ducted central entries on the QPL. Sample qualifying models include MXZ-SM36NLHZ and MXZ-SM60NLHZ.
Does Goodman qualify for Mass Save rebates?
Yes, but only for ducted central installations. Goodman has 636 entries on the QPL with 10 outdoor models, all in the newer GZV7 series. The older GSZC18 series does NOT appear on the current QPL. Goodman does not have any mini-split entries. If you want a ductless system, consider one of the other 11 NuWatt brands that qualify for mini-split rebates.
What is the Heat Pump Installer Network (HPIN)?
The Heat Pump Installer Network (HPIN) is the Mass Save-approved group of contractors authorized to install rebate-eligible heat pump systems. Having QPL-qualifying equipment is only half the requirement — the installation must also be performed by an HPIN-certified contractor. NuWatt Energy is a fully certified HPIN contractor. We handle equipment selection, Manual J load calculations, installation, and all rebate paperwork.
Do I need an integrated control for my heat pump?
Only if you are keeping your existing gas or oil furnace/boiler as a backup (dual-fuel setup). Mass Save requires an approved Integrated Control (IC) to manage the switchover between the heat pump and fossil fuel backup. Approved controllers include the Carrier Infinity, Google Nest (3rd Gen+), Cielo Breeze, Flair Puck Pro, Bosch BCC100, and Fujitsu UTY-TTRX. If your heat pump fully replaces your old system with no backup, no IC is required.
How much is the Mass Save heat pump rebate in 2026?
Mass Save offers three rebate tiers in 2026: Whole-Home at $2,650 per ton (capped at $8,500), Partial at $1,125 per ton (capped at $8,500), and Basic at $250 per ton (capped at $2,500). Additional bonuses of $500 for proper sizing (Manual J) and $500 for weatherization are available. The 0% HEAT Loan covers up to $25,000 of remaining costs. There is no federal residential tax credit in 2026 — Section 25C expired December 31, 2025.
Can I get Mass Save rebates for a ductless mini-split?
Yes. Ductless mini-splits are eligible for Mass Save rebates as long as the system meets QPL criteria: HSPF2 8.5+, SEER2 15.2+, HCR 70%+ at 5°F, and COP 1.75+ at 5°F. Eleven of the twelve brands NuWatt installs have qualifying mini-split models. The exception is Goodman, which only has ducted central entries on the QPL. Popular qualifying mini-split brands include Mitsubishi, Fujitsu, Daikin, and LG.
What refrigerants do QPL-qualifying heat pumps use?
As of 2026, only heat pumps using R-32 (GWP 675) or R-454B (GWP 466) refrigerants appear on the Mass Save QPL. R-410A systems (GWP 2,088) were removed from the QPL effective January 1, 2026. Any heat pump using R-410A receives $0 in Mass Save rebates. NuWatt only installs R-32 and R-454B systems to ensure full rebate eligibility.
What is the HCR at 5°F and why does Mass Save require it?
HCR at 5°F (Heating Capacity Ratio at 5 degrees Fahrenheit) measures what percentage of rated heating capacity the heat pump maintains at 5°F outdoor temperature. Mass Save requires 70% or higher, meaning the system must deliver at least 70% of its rated capacity when the temperature drops to 5°F. This ensures the heat pump can handle Massachusetts winter conditions without relying heavily on backup heat. A higher HCR means better cold-weather performance and lower backup heating costs.
