  • Dave was very helpful in getting an old generac whole home generator up and working at my new house. I am generally very handy and he was very informative and helpful in getting the generator functioning. Dave went out of his way to walk me through the repairs. I have no hesitation in using the company again for service and sales.

  • They fixed my generator right away. The repair was covered by the warranty so I didn't have to pay anything. They did all the required paperwork. I didn't have to do anything. They followed up with me, after the repair, to make sure my generator was still working properly. I strongly recommend you call them.

  • Beyond my expectations. The technician arrived on time and knew the generac generator inside and out. He was friendly and very informed about the product. He could have just left after fixing the problem, but instead he waited to make sure my battery was charging properly. I feel lucky to have found someone that I can trust my maintenance to. I like the Generac generator and it's features and it's good looking design.

  • After using our generator for 12 days straight after hurricane sandy (oct. 2012) our generator went caput! after thinking the repair would be costly it turned out to be an oil change. that was the first time we used dave. the second time (other than regular upkeep) dave had a bigger issue to deal with. since there are many parts that can falter it was a process of elimination that our generator has been confidently fixed. dave is polite, clean, timely, and CAN fix any problem. highly recommended.
