Founded in 1964, Northeast Generator was started by Louis Holzner as a division of his electrical contracting company. With extensive experience in the electrical field and construction, Lou realized the importance and demand for a turnkey generator company in Connecticut. With the help of his son, Mark Holzner, Lou broke Northeast Generator off as its own company to focus on providing families, businesses, governments, and organizations the reliable home and commercial generators, along with the expertise they deserved.

Northeast Generator has always been responsive to any service requests. This is my second time around with them. For various reasons having nothing to do with their service, I had switched to another service company for a short period of time. The second service company was terrible to work with and didn’t last long with me. I switched back to Northeast Generator, and they have been great; very responsive. I wish I never switched from them!)
Northeast Generator has been servicing our home for over 10 years. Their service technicians have always arrived on time, clearly explained the work they are doing and are very friendly. During a routine service last year, the technician reported a potentially serious issue with our propane gas line. They quickly worked out a solution, scheduled the follow-up visit and resolved the problem quickly and efficiently. Our generator has functioned flawlessly during this period. The office staff is very helpful and has always been able to schedule their regular maintenance visits to fit our schedule.)
We switched to Northeast Generator this past year after having bad service from another company. Northeast came highly recommended and I agree with the recommendation. They are very easy to work with, having great communications and scheduling, and are very knowledgeable. We are very happy that they are servicing our generator)
Great Service, Quality and Prices! I was very pleased with my most recent service by Northeast Generator. Always there to serve us, call with reminders when service is due with great prices and quality service. Highly recommended.)
Northeast has been servicing my older propane generator for several years now. Their representatives always treat me with respect and in a professional manner. They have worked through very hot weather and deep snow. Work has been very good and priced reasonably.
My yearly maintenance was performed this week, the technician was friendly and efficient, after he completed the internal checkup he completely cleaned the outside making it look brand new. Thank you Northeast Generator.
