Greenfield, Massachusetts serves as the county seat of Franklin County and the commercial hub of the upper Pioneer Valley. Situated where the Green River meets the Deerfield River just before they join the Connecticut, Greenfield enjoys a beautiful natural setting -- but that river valley geography also makes it a corridor for powerful storms. Ice events, nor'easters, and summer thunderstorms can all leave Greenfield neighborhoods without electricity for extended periods. Powers Guaranteed Services brings over 30 years of generator expertise to Greenfield from our home base in Swanzey, New Hampshire, less than an hour north.
As the closest major Massachusetts city to our headquarters, Greenfield is a community we know well and serve frequently. Our technicians are licensed in Massachusetts and experienced with the local permitting and inspection process.
From the tree-lined streets near the Common to the rural properties along the town's edges, Greenfield homes and businesses benefit from having backup power they can count on.
Greenfield is a town that supports local businesses and values honest, straightforward service. That is exactly what we deliver.
We provide free in-home consultations where we assess your electrical panel, discuss your priorities, and recommend a system that matches your home and your budget. No pressure, no surprises.
In addition to Greenfield, we serve Northfield, Deerfield, Shelburne, Montague, Turners Falls, Sunderland, and communities throughout Franklin County. Our Swanzey location puts us within easy reach of the entire upper Pioneer Valley, and our crews are in the area regularly for installations and service calls.
Do not let the next storm catch your Greenfield home unprepared. Contact Powers Guaranteed Services at 800-853-7202 or submit a request through our website. We will schedule a convenient time to visit your property and walk you through your options.
