Step 3 | Mass Save® Kickoff
We handle the details so you don’t have to navigate the rebate process alone
Navigating rebates and financing through the Mass Save® program can be complex—but it shouldn’t be your burden to bear. At SumZero Energy Systems, we’ve built an entire Concierge Team to guide you through every step of the process.
From the moment your project begins, we take ownership of your Mass Save® experience—from scheduling assessments to filing every piece of paperwork—so you can focus on getting comfortable in your home.

Mass Save® Assessment Coordination
Once you’re onboarded, our Concierge Team books your Home Energy Assessment (if you haven’t had one yet). This step is required for most rebates and loans and ensures your home qualifies for the available programs.
We coordinate directly with Mass Save® and local partners to make this as simple and hands-off for you as possible.
0% HEAT Loan Application Support
If you’re planning to finance your system, we help you apply for the Mass Save® 0% interest HEAT Loan. Our team walks you through:
- Eligibility requirements
- Bank/lender connections
- Required documents and timing
- Processing steps to get approved quickly
We don’t just point you in the right direction—we walk you all the way there.
Pre- and Post-Installation Documentation
Our office handles all Mass Save® paperwork for your system. That includes:
- Pre-approval forms for rebates
- Equipment eligibility confirmations
- Post-installation submissions and final inspection coordination
- Any follow-ups or corrections requested by the program
Why This Step Matters
Many homeowners underestimate the complexity of Mass Save®. A single form error can delay rebates or HEAT Loan approvals. We remove that risk by doing the heavy lifting ourselves—accurately, completely, and on time.
