Got four quotes and not only was Generator Supercenter of NH the cheapest, they were the only ones willing to dig the lines and hook up to the propane tank. Weather was horrible, ground was frozen and the team did a great job. Very quick and thorough responses to questions. Would highly recommend.
We recently selected the Supercenter to install a Generac at a location that, due to local codes, presented a variety of unique problems regarding equipment location. Through endless patience by their rep ‘Casey,’ the problems were solved to our complete satisfaction. Jack, the master electrician, was very knowledgeable solving a variety of historical and vexing electrical problems we had. To conclude, I highly recommend them. They’re the best!
Excellent experience from sales to installation. Seamless all the way. Install team was amazing and very efficient. Great communications along the way. Best prices too. I liked the idea that this is totally what this firm does so they are true experts in their field. Everything went off like clockwork. This is my 2nd Generac due to moving, so I come with some experience in saying this firm is very professional. Highly recommend!
