Q: How is generator sizing calculated?

Sizing by home + electrification: 8-14 kW : essential circuits (heat, fridge, sump pump, well pump, select outlets). 14-22 kW : whole-home including AC + heat pump with load shedding. 22-26 kW : fully electrified home (heat pump + EV + induction range). Pro Build runs load calc during the on-site visit.

What Makes a Ashland Generator Project Specific

Generator installation in Ashland drives three critical decisions:

Generator sizing for whole-home vs essential circuits. Whole-home (14-26 kW) backs every circuit; essential circuits (8-14 kW) backs heat, fridge, sump pump, well pump, select outlets. Pro Build runs load calculation per appliance + critical needs to size correctly.
Fuel type selection. Natural gas (where available) — unlimited runtime, no tank to maintain. Propane — works anywhere but requires 250-500 gal tank ($1.5K-$3K added). Generators run 4-7 days continuous on propane tank, indefinitely on natural gas.
Transfer switch type. Automatic transfer switch (ATS) starts generator when power fails, transfers load. Manual transfer switch requires homeowner action. ATS standard for whole-home; manual common for portable + essential circuits.

Greater Boston / MetroWest generator installations serve high-volume single-family market. Whole-home Generac, Kohler, Briggs & Stratton standby generators (14-26 kW) standard.
