The 3 Mass Save Designations Explained
Mass Save (the consortium funded by Eversource, National Grid, Unitil, Cape Light Compact, Berkshire Gas, and the MA municipal aggregators) maintains three distinct contractor authorizations. Each unlocks different program filing capabilities:
- 1. General Mass Save Approved
- Base-level authorization. Required to file rebates on: gas boilers, gas furnaces, central air conditioners, gas water heaters, smart thermostats, HVAC tune-ups. Application requires basic insurance, MA HIC registration, and program orientation. Typical contractor capabilities: standard HVAC equipment swaps within existing fuel category.
- 2. Heat Pump Coach (HPC)
- Specialized authorization layered on top of General Approved. Required to file: whole-home heat pump rebates ($10K-$16K), partial heat pump rebates ($1,250/ton), heat pump water heater rebates. Requirements include manufacturer-specific training (Mitsubishi, Fujitsu, Bosch certifications common), AHRI matched-pair documentation discipline, Manual J load calculation capability, and annual recertification. The HPC ID is a numeric identifier published in the Mass Save contractor directory.
- 3. Income Eligible Enhanced Authorized
- Additional authorization for contractors handling income-qualified rebates (below 60% Area Median Income). Requires income verification process training, additional documentation discipline, and willingness to work with longer payment cycles. Many HPCs hold this designation; some hold only standard-tier HPC. Required to file Income Eligible Enhanced rebates ($16K heat pump, 100% weatherization coverage).
What Each Tier Lets a Contractor File
Knowing which rebates a contractor can file before signing prevents the surprise of an uncollected rebate after the install. Capability by tier:
| Rebate program | General | HPC | IE Enhanced |
|---|---|---|---|
| Gas boiler $400-$700 | ✓ | ✓ | ✓ |
| Central AC $250-$750 | ✓ | ✓ | ✓ |
| HVAC tune-up $50-$100 | ✓ | ✓ | ✓ |
| Smart thermostat $100 | ✓ | ✓ | ✓ |
| Heat pump water heater $750 | — | ✓ | ✓ |
| Partial heat pump $1,250/ton | — | ✓ | ✓ |
| Whole-home heat pump $10,000 (standard) | — | ✓ | ✓ |
| Whole-home heat pump $13,000 (moderate income) | — | partial | ✓ |
| Whole-home heat pump $16,000 (IE Enhanced) | — | — | ✓ |
| 100% weatherization (IE Enhanced) | — | — | ✓ |
| Panel upgrade $4,000 (paired) | — | ✓ | ✓ |
How to Verify a Contractor's Tier in 60 Seconds
Mass Save publishes a public contractor directory with tier information. Verification takes 60 seconds:
Total time: PT2M
- Step 01
Visit masssave.com/find-a-contractor
Mass Save's official contractor lookup. Free, no account required. Updated by the program administrators within 48 hours of any tier change. - Step 02
Search by ZIP code or contractor name
ZIP-based search returns all authorized contractors serving that area, with their tier designations visible. Name search confirms a specific contractor and shows their exact authorization level. - Step 03
Confirm the HPC ID matches the contractor's claim
Real HPC contractors quote their numeric HPC ID on request. The number shown in the directory should match the number the contractor recites. Mismatch = the contractor is misrepresenting status. - Step 04
Check for Income Eligible Enhanced flag
If you qualify for Income Eligible Enhanced tier, verify the contractor holds that specific authorization. Many HPCs do not — they can file standard heat pump rebate but not the IE Enhanced version. - Step 05
Cross-reference the AHRI Reference Number on the proposal
Real HPCs include the AHRI Reference Number on every heat pump proposal — proves the equipment is a verified matched pair. Skipping this means the rebate filing will fail post-install verification regardless of contractor authorization.
Red Flags That a Contractor's Tier Doesn't Match Their Claim
Common patterns from contractors who claim Mass Save authorization they don't actually hold:
- 'We work with Mass Save' — vague language. Real contractors say their specific designation: 'We are a Mass Save HPC contractor, our HPC ID is 12345.'
- HPC ID not in the public directory — search masssave.com/find-a-contractor. If the contractor isn't listed, they aren't authorized at the level claimed.
- Quote without AHRI Reference Number — heat pump quotes without AHRI matching cannot file the rebate. Real HPCs include it on every proposal.
- 'We'll help you file the rebate' — the rebate is filed by the contractor on the contractor's account. Homeowners do not file Mass Save rebates directly. Contractors who promise to 'help you file' typically subcontract the install to a real HPC and take a margin.
- Heat pump rebate quoted with non-HPC tier — only HPCs file heat pump rebates. A contractor with only General Mass Save authorization who quotes a heat pump rebate is misrepresenting either the rebate or their authorization.
- No income tier verification offered — IE Enhanced authorized contractors proactively check income tier before quoting because it changes the rebate stack. Contractors who never mention income tier usually don't hold IE Enhanced authorization.
