Working with the Commander team has been fantastic. Everything went exactly as they said it would on installation and they keep the system running all year round. I’ve recommended them to both family and friends.

Nelson – Setauket, NY

30kW Whole House Generator

Living on Long Island means you have to have a generator, no questions asked. The Commander team was there before Sandy ensuring I was ready and after to ensure I was running. I can’t say enough about their great service!

Vince – Islip, NY

60kW Whole House Generator

A generator doesn’t seem like it would be the topic of everyday conversation, but when you’re house has it’s lights on for 14 days when everyone else has no power, it’s the only thing people want to talk about. Thank you.
