2nd Generation Family Business

Established 1979

A. Charpentier Power Systems

Founded by Andre Charpentier in 1979, we are now a second generation, family-owned and run business, with daughter Anne and son-in-law Peter taking over the reigns in 2005. Peter has worked in the family business since 1983.

Old-fashioned business principles are still at the forefront today – quality equipment, quality workmanship, at a fair price. We are proud to say that our business and customer base has been increasing significantly every year and the majority of our advertising is by “word of mouth”.

What do we do?

Generators are our only business! We sell and service emergency generators, they are no longer a luxury, these days with all the power outages, storms and hurricanes in the Northeast, they are a necessity. Our customers include both residential and commercial businesses. We sell Kohler and Winco generators and service all brands from a 5Kw to 500Kw.

Customer Testimonials

Stephen Blanche

I highly recommend A. Charpentier Power Systems to service any generator requirements. Peter Viens and his staff serviced my older ‘stand alone’ generator for many years in a very professional manner.

This year I required a replacement unit and Peter once again was quick to respond. He installed the new generator and had me back on-line in a very short time. He can totally be trusted to manage my service needs.
