My standby generator was displaying a master caution light. I called Casco Bay Gen. at about 10AM and spoke with Steven. He arranged for a service tech to check out my problem on the same day. Adler showed up at my door at about noon(a very pleasant and polite young fellow). He went straight to work , diagnosed and corrected the problem and got us back in service by 12:30. What more could you possibly ask for than this?

Casco Bay Generators are terrific. We had a complex install - location, power source, large property with electric heat, many details to get right, and they did a terrific job. All their personnel from the estimator to the installer were competent, kind and intelligent people. I highly recommend them!

We had a generator and heat pumps installed about 4 weeks ago. Both crews did an outstanding job. So professional and courteous. And despite the sweltering heat completed the install for each unit in less than a day! From the beginning of this project to the end we would highly recommend Casco Bay.
