of qualifying insulation upgrades, set by the Mass Save program administrator at assessment, not by Complete Home Comfort.
What Mass Save Home Energy Services actually is
Mass Save Home Energy Services is a Massachusetts energy-efficiency program funded and run by the state's participating utility companies, not by Complete Home Comfort. This company is an approved insulation contractor working within that program as part of its wider energy programs work, which means Complete Home Comfort can enroll a home, carry out the approved measures, and file the incentive paperwork. The program administrator, not Complete Home Comfort, decides what qualifies and what incentive level applies.
For the homeowner, that structure turns into three concrete things. The first is a no-cost home energy assessment that identifies what the house actually needs. The second is the incentive itself: through Mass Save Home Energy Services, eligible homeowners can receive incentives covering up to 75 percent of qualifying insulation upgrades. The third is that Complete Home Comfort files the enrollment forms, the scope submission, and the close-out documentation in house, so none of that paperwork falls on the homeowner to track down.
The path from a phone call to an installed rebate
The steps below run in the order Mass Save Home Energy Services requires. Select any step to see what it involves and what it means for eligibility or for the incentive.
-
1
Book the assessment
A Massachusetts homeowner in the company's service area calls or books online, and Complete Home Comfort schedules a no-cost home energy assessment. Booking does not create any obligation.
The assessment covers the whole house, not just insulation, so the visit also flags anything else relevant to comfort or safety before any scope gets written.
-
2
The visit and the scope
A technician walks the house, tests it, and writes a proposed scope of insulation and air sealing work matched to what the house needs.
Knob-and-tube wiring, vermiculite, mold, and active water are checked for at this visit, because any of them can stop a scope from moving forward until resolved.
-
3
Program review and approval
The proposed scope goes to Mass Save Home Energy Services. The program administrator reviews it and decides what is approved and at what incentive level.
Approval depends on the scope itself, which measures are involved, and the current incentive level the administrator has set, which can change between enrollment periods.
-
4
The number in writing
Once approved, the incentive amount and the homeowner's remaining share come back in writing, before any work is scheduled.
Nothing is scheduled for installation and no work order gets signed until this written number is in hand. That is a standing rule, not a suggestion.
-
5
Install
Complete Home Comfort schedules and installs only the approved measures, using the scope that was already approved.
Air sealing is completed before insulation goes in on any job that includes both, matching the sequence used across every insulation service the company performs.
-
6
Close-out documentation
After the install, Complete Home Comfort files the completion paperwork with the program administrator to close out the rebate.
This step is what actually releases the incentive, so it gets filed promptly rather than left for the homeowner to chase down later.
-
7
Post-install inspection
Some scopes include a program-required inspection after the work is finished, confirming the installed measures match what was approved.
Not every scope requires one, but where Mass Save Home Energy Services does ask for a post-install inspection, that visit is what finalizes the file.
What Mass Save insulation rebates typically cover
The program approves specific insulation and air sealing measures, not every improvement a house might need. What applies to a given home gets decided at the assessment, not guessed at ahead of time, but these are the general lines the program works within.
Typically included in scope
- Attic insulation, including knee wall and sloped ceiling areas
- Air sealing at the attic top plate, chases, hatch, and rim joist
- Wall insulation and basement or rim joist insulation
- Removal of old or damaged insulation where the approved scope calls for it
Outside the program's scope
- Cosmetic finish work and general home renovations unrelated to the building shell
- Structural repairs that are not part of an insulation or air sealing measure
- Any work outside the approved measures list, quoted and scheduled separately from the Mass Save number
The barriers that can pause a project before it starts
A handful of conditions common in older Massachusetts homes have to be resolved before Mass Save Home Energy Services will approve work, because the program will not fund insulation installed over an unresolved hazard. Finding one of these does not end a project. It changes the order of operations.
None of this is unusual. The housing stock in Franklin and the towns around it is old enough that one of these shows up on a meaningful number of assessments, and finding it before work starts, not after, is exactly what the visit is for.
What decides your share, and why there is no single number
No two Mass Save insulation rebates come out the same, because a few different variables move independently on every house. These are the factors that decide the homeowner's share, not a price.
A house that needs attic, wall, and rim joist work together has a larger approved scope than one that only needs the attic addressed.
The program approves specific measures for a specific house. What gets approved shapes what the incentive can apply toward.
Mass Save Home Energy Services sets its own incentive level, up to 75 percent of qualifying work, and that level is confirmed at assessment, not fixed in advance.
Where knob-and-tube wiring, vermiculite, mold, or active water has to be resolved first, that work sits outside the insulation scope and changes the total picture.
Why the order matters, and what the license means here
The order is not a formality. Assessment comes before scope, because the scope cannot be written until someone has actually looked at the house. Scope comes before schedule, because Mass Save Home Energy Services has to approve the scope before any date gets set. And no work order gets signed before the incentive number is in writing, because that number is what makes the homeowner's share knowable in the first place. Skipping any of that order is how a homeowner ends up committed to work before knowing what it costs them.
