Boston neighborhood guides
Boston neighborhoods vary materially on housing stock, historic-review constraints, and install cost. Each guide covers what's specific to that neighborhood — BBAC review in Back Bay, Beacon Hill Architectural Commission in Beacon Hill, South End Landmark District, triple-decker installs in Dorchester, multi-unit logistics in Allston/Brighton.
What's specific to Boston
Boston's South End and Back Bay are dominated by 1850s–1870s Victorian brick and brownstone rowhouses built four to five stories on filled tidelands, with party walls and no rear yards that materially constrain outdoor condenser placement. Triple-deckers are common in Dorchester, Roxbury, and Hyde Park; West Roxbury and parts of Roslindale lean post-war single-family. Most homes do not have original central ductwork, which is why ductless mini-split heat pumps are the dominant retrofit path here.
Boston climate & sizing
Boston Logan's ASHRAE 2009 99% heating design dry-bulb temperature is 12.4°F — milder than inland Worcester thanks to coastal moderation, but humid enough that summer dehumidification capacity (not raw BTUs) often drives equipment sizing. Cold-climate certification is still required for whole-home Mass Save qualification.
99% winter design temperature: 12.4°F (Boston Logan Int'l (ASHRAE 2009)). Heat-pump capacity at this temperature is the number to validate when reviewing a Manual J load calculation.
Mass Save sponsor & utility
Mass Save in Boston is administered through Eversource (electric) and National Grid (gas). That sponsor processes your heat pump rebate (up to $8,500 standard in 2026, up to $16,000 enhanced for income-qualified households) and the HEAT Loan referral. See the full sponsor directory to verify your account.
Note: Boston Gas Company d/b/a National Grid.
Permits & historic review in Boston
Residential HVAC permits in Boston are issued by the Inspectional Services Department (ISD), Building Division. Gas work requires a separately-pulled gas permit; your licensed installer files both. Full per-city permit fees, inspection process, and timelines: Boston HVAC permits guide.
The Back Bay Architectural Commission and Beacon Hill Architectural Commission both require approval for HVAC condensers and mini-split heads visible from any public way; rooftop placement set well back from cornices is the typical approved location for those neighborhoods.

Whole-Home Heat Pump Rebate
$2,650 /ton
Capped at $8,500 per home
The installed heat pump must be the sole source of heating and cooling for the spaces served. Equipment must be ENERGY STAR Cold Climate certified and listed on the Mass Save Heat Pump Qualified Products List (HPQPL). A Manual J load calculation is needed to qualify for the sizing bonus and is industry-standard practice on Mass Save projects.
Partial-Home / Supplemental Heat Pump Rebate
$1,125 /ton
Capped at $8,500 per home
Heat pump installed alongside an existing primary heating system. Equipment must be on the HPQPL. Lower per-ton rebate reflects supplemental rather than sole-source use.
Basic Heat Pump Rebate
$250 /ton
Capped at $2,500 per home
New for 2026. Applies to replacing an existing heat pump with a new qualified HPQPL-listed heat pump, or conditioning a previously unconditioned space.
$500 Right-Sized Equipment Bonus Partial-home
Partial-home installs only. Equipment must be sized to meet 90–120% of the total heating load at the outdoor design temperature, documented via an ACCA Manual J load calculation submitted with the rebate application.
$500 Weatherization Bonus Partial-home
Partial-home installs only. Requires a Mass Save Home Energy Assessment plus installation of the recommended weatherization (typically air sealing and insulation) within one year prior to or up to six months after the heat pump installation.

Status as of 2026-05-27: neither 25C nor 25D has been reinstated or replaced by Congress. Pending bills (e.g. H.R. 616) have not advanced. Pre-2026 §25D installs may carry forward unused credits.
