Unlock Up to $10,000 in Instant Mass Save® Rebates with Denommee’s Whole-Home Heat Pump Upgrades

For Massachusetts homeowners looking to transition to high-efficiency, all-electric home heating and cooling, there's never been a better time to act. Thanks to the Mass Save® program, homeowners may now qualify for up to $10,000 in rebates when upgrading to a whole-home heat pump HVAC system. But here’s the part many don’t know:

Denommee Plumbing, HVAC & Electric offers these rebates as instant savings—helping you skip the long wait and reduce your upfront investment dramatically.

Unlike many HVAC contractors in the Mass Save® Heat Pump Installer Network (HPIN), Denommee is among the few who are actively offering instant rebates at the time of installation, not weeks or months later. Plus, with our exclusive partnerships and streamlined processes, we can expedite Home Energy Assessments (HEAs) and coordinate weatherization improvements, speeding up your entire project timeline.

Here’s how we do it—and why it matters.

What Are Mass Save® Instant Rebates?

The Mass Save® program offers generous financial incentives for Massachusetts homeowners who install qualifying high-efficiency heat pump systems. These rebates can cover up to $16,000 of your project costs—especially when you fully convert to a whole-home heat pump solution and weatherize your home accordingly.

While most contractors help homeowners apply for the rebate after installation—resulting in wait times of 6 to 12 weeks or more—Denommee delivers these rebates instantly, applying them directly to your quote and reducing the cost from day one.

Benefits of Instant Rebates:

• No waiting for checks or reimbursements

• Lower upfront costs = less financing or out-of-pocket spending

• Improved affordability for full system upgrades

• Quicker project approvals and installations

Why Not All HPIN Contractors Offer Instant Rebates

The Mass Save® HPIN (Heat Pump Installer Network) includes a wide range of contractors across Massachusetts. While all HPIN members must meet certain training and performance standards, not all of them are willing or equipped to deliver instant rebates.

This added layer of service requires:

• Deep knowledge of the Mass Save® rebate structure

• Advanced administrative coordination and documentation

• Relationships with program sponsors and energy efficiency partners

• A commitment to simplifying the process for homeowners

Denommee has invested in these capabilities—and it’s why more homeowners choose us when making the switch to a high-performance, energy-efficient heat pump system.

Denommee's Advantage: Expedited HEAs and Weatherization

To unlock the full value of the $10,000 rebate, your home must meet weatherization requirements (like proper insulation and air sealing), and you must complete a Home Energy Assessment (HEA) through Mass Save®. This process ensures your home is ready to fully benefit from an all-electric heating and cooling system.

The problem? HEAs and weatherization projects often cause delays, with some homeowners waiting weeks—or even months—to complete these critical steps.

Denommee Solves That Problem.

Thanks to our strategic partnerships with authorized weatherization contractors and energy assessment providers, we can:

• Schedule your HEA quickly

• Coordinate required weatherization work faster

• Keep your project timeline on track

• Ensure full rebate eligibility from day one

You don’t have to worry about chasing down multiple companies or navigating confusing requirements. Denommee manages it all—start to finish.

• Efficient heating—even in cold New England winters

• Powerful, reliable air conditioning in summer

• Zero emissions on-site (great for decarbonization goals)

• Whisper-quiet operation

• Smart, zoned comfort control
