Randall and his team were very professional and thorough. My property was spotless
upon completion. I am very impressed with their commitment to quality and customer
service. I highly recommend this company to anyone in the market for a generator.
Very friendly and professional. I called when our generator was not working during our
extreme cold spell and they helped troubleshoot over the phone. Excellent customer
service. Would recommend them to all my friends and family
It was a thorough pleasure dealing with the "Generator Supercenter of Western Mass"…
reasonable, knowledgeable, and swift. Their crew deserves a five star rating.
Randall and his team from the Generac Supercenter have been an awesome company
to work with. The first time my wife and I met with him, we knew this was the company
to go with. If there was a sixth star, I would give it to this company.
Our experience was amazing. The superstore staff was professional, and the install
went without a hitch. Randall was very personable and checked in during every phase
of the process. I would highly recommend them if you are looking for a generator.
