What's specific to Somerville
Winter Hill and the corridor stretching toward Davis Square are dominated by wood-frame Somerville-style triple-deckers and two-families on narrow 2,500–4,000 sq ft lots. The City Council voted in 2023 to fully re-legalize triple-decker construction. Tiny lot setbacks, shared walls, and condenser placement constraints make ductless mini-splits the dominant heat-pump retrofit pattern.
Somerville climate & sizing
Norwood Memorial reads 8.8°F design winter, but dense urban Somerville often tracks closer to Boston Logan (12.4°F) due to heat-island effect. Limited yard space favors wall- or roof-mounted condensers over ground installations.
99% winter design temperature: 8.8°F (Norwood Memorial — nearest ASHRAE 2009 station (Boston Logan 12.4°F applied where urban heat-island dominates)). 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 Somerville 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 Somerville
Residential HVAC permits in Somerville are issued by the Somerville Inspectional Services Department, Building Division, 1 Franey Road. Gas work requires a separately-pulled gas permit; your licensed installer files both. Full per-city permit fees, inspection process, and timelines: Somerville HVAC permits guide.
The Somerville Historic Preservation Commission administers six local historic districts including Westwood Road, Powderhouse Boulevard, and parts of Spring Hill; exterior changes visible from a public way that would irreversibly alter design, materials, or appearance require review.

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.
