Founded in 1994 by Al Powers, installing and servicing generators has been at the core of our business for 28 years and counting.

We have grown from a one-person operation to a company of over 70 valuable staff members and technicians who align together on our values of integrity, service and communication.

We keep our word to our customers by consistently epitomizing these values on each and every job we perform.

Superior Service

Our A+ standing with the Better Business Bureau is evidence of our top-quality customer service.


We never come to you with just one product, so you have a full range of options that will suit your budget and needs.

Al Powers

Al began his career as an electrician and started his own business at 21 years of age. Faced with the building recession of the late 80s, Al went to work as a maintenance director. He returned to his own business about 5 years later and decided to focus on standby generators. Al had no previous experience with generators, but it seemed to him like a niche for the taking. It became the first generator company that also provided turn-key installations in Central and Northern New England. In 2020, Powers Guaranteed Services celebrated it’s 25th anniversary with 45 employees and growing.
