128 Plumbing, Heating, Cooling and Electric, a family-owned contractor based in the greater Boston area with a new location opening in Seabrook, New Hampshire, has been named the 2026 residential contractor "HVAC All-Star" by trade publication ACHR News. Founded in 1992 by David Williams and now led by his son Ryan, the company has grown to about 170 employees and 120 vehicles while staying privately owned by the founding family, a status it formalized last year through a third-party "Evergreen" certification.
On the home-comfort side, 128 works on hydronic (hot water-based) heating systems, heat pumps, mini-splits, gas furnaces, and even oil-fired furnaces. It holds top-tier certifications with Mitsubishi Electric and Navien, and is an authorized installer of Tesla's solar, battery-storage, and energy-management equipment. The company also installs heat pumps through Mass Save, the Massachusetts utility-run program that helps homeowners pay for efficiency upgrades like insulation and heat pumps.
For homeowners outside Massachusetts, the main takeaway is less about this particular company and more about the broader trend it reflects: heat pumps and home electrification work are becoming a growing, visible part of mainstream HVAC business, alongside traditional systems. If you're considering a heat pump or other upgrade, checking whether your state runs a similar utility rebate program to Mass Save is worth a look, since availability and incentives vary by state.
