My husband and I had a great experience with Generator Supercenter. The staff members were friendly and well informed. Very pleased and it was installed before hurricane season started.

Purchased my generator about 7-8 years ago and have had Generator Super Center service it for me since it was installed. Have never had an issue with it and the service I get from them is outstanding. I highly recommend anyone buying a generator to use these folks.

Great group of people who have kept my generator operating for years. I always send a mental thank you when for whatever reason I lose power and I hear the generator kick on. Grateful for their dependable service.

Generator Supercenter is top-notch! We purchased a whole house generator from them in ~2013 and have been using them for maintenance, monitoring, and service as needed. Highly recommend these folks.

Generator Supercenter is a huge company, yet is dedicated to each individual customer. They price matched, exceeded install time, and have been prompt and responsive with service. I have and will continue to recommend them to our friends!

Our experience with Generator Supercenter was a great experience. Our salesman was very professional, friendly and very knowledgeable. The presentation & process was very quick & easy. I would highly recommend this company.
