The honest answer: no standalone HRV program in Fall River
Mass Save treats ventilation as a supporting measure in Fall River, not a headline program — here's where the actual money is.
The first is an instant discount: Mass Save pays qualifying equipment vendors and contractors up to $500 off a qualifying HRV or ERV unit at the point of sale, no separate rebate application needed on your end. The second is a weatherization-linked rebate, cited by contractor guides tracking Mass Save's 2026 program at $400 to $800, available when the ventilation unit is installed as part of a broader insulation or air-sealing project through Mass Save. As a National Grid customer, your Mass Save home energy assessment and any resulting HRV/ERV paperwork route through National Grid's program administration — National Grid customers can also reach Mass Save directly at 1-866-527-7283.
Instant discount at point of sale on qualifying HRV/ERV equipment, applied by the vendor or contractor.
Rebate when HRV/ERV is installed as part of a Mass Save insulation or weatherization project.
Ventilation installed with no other Mass Save-eligible project underway — the instant discount still applies to qualifying equipment, but nothing else does.
What the equipment has to meet
- Energy recovery ventilators (ERV) need an enthalpy recovery ratio of at least 75% at both heating and cooling design conditions, tested to AHRI Standard 1060
- Heat recovery ventilators (HRV) need a sensible energy recovery ratio of at least 75% at heating design conditions, tested to the same AHRI standard
- Installation has to go through a Mass Save-authorized contractor who can apply the instant discount and, if applicable, file the weatherization-linked rebate
Why Fall River homes end up needing HRV anyway
Once a Fall River home gets air sealed as part of a Mass Save weatherization job, it stops "breathing" the way older, leakier houses do. That's good for the heating bill and bad for indoor air quality unless something replaces the airflow — which is the job an HRV or ERV does, recovering heat from the outgoing air in the process.
How to claim it in Fall River
- Book a free Mass Save home energy assessment — it's the same required first step as every other Mass Save rebate, including this one
- Ask your assessor or contractor whether an HRV or ERV makes sense for your project, especially if you're already sealing the attic, walls, or basement
- Confirm the equipment meets the AHRI 1060 recovery-ratio thresholds before you buy — your contractor should know which units qualify
- Have your Mass Save-authorized contractor apply the instant discount at purchase, and file the weatherization-linked rebate if the ventilation work is bundled with an insulation or air-sealing project

Common questions
Is there a standalone Mass Save HRV rebate in Fall River?
No. Mass Save has never built HRV/ERV into a dedicated standalone rebate program the way it has for heat pumps. Fall River homeowners can still get a real instant discount of up to $500 on qualifying equipment at the point of purchase, or $400 to $800 when a heat or energy recovery ventilator is installed as part of a broader Mass Save insulation or weatherization project.
What equipment qualifies for the Fall River HRV/ERV discount?
The unit has to meet Mass Save's efficiency threshold under AHRI Standard 1060: an energy recovery ventilator needs an enthalpy recovery ratio of at least 75%, and a heat recovery ventilator needs a sensible energy recovery ratio of at least 75%, both at design heating and cooling conditions. Installation has to go through a Mass Save-authorized contractor.
Compared to the headline heat pump numbers Fall River homeowners see elsewhere on this site, this is minor money — useful, but not a reason to install ventilation by itself.
