Generator installation in Duxbury, Massachusetts covers whole-home automatic standby generators (14-26 kW typical scope $8,000-$18,000), essential-circuits standby (8-14 kW $5,500-$11,000), and portable generator + interlock kit installations ($1,200-$2,800). Pro Build holds Massachusetts Master Electrician + Plumbing/Gas Fitting licenses in-house — required for the electrical, gas line, and transfer switch work that generators need.
Why Duxbury Homes Need Backup Power
Generator installation in Duxbury 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.
South Shore generator installations serve mid-century single-family stock — storm-related outages drive demand.
