customer testimonials

Ryan Thelin

Used Gilliam Generator for scheduled maintenance, the old company I used was farther away and never on time. Glad to have a company so close now that I can rely on for service on my generator. Prompt, and was able to answer all my questions!

Dave Radford

Pat came today to do a service on my generator. He found things my previous company never spotted, he adjusted my tappets and updated my firmware. I can recommend his services to anyone.

I recently had my generator serviced by Gilliam Generator Service in Neptune, NJ, and the experience was fantastic. The team was incredibly knowledgeable and quickly diagnosed and fixed the issue. Their customer service was excellent, and they kept me informed throughout the process. The maintenance work was thorough and professional. I highly recommend them for any generator maintenance and repairs. Thank you for your outstanding service! Truly thank you.
