Team PhotoServing our Central PA neigbors since 1968.

Near the end of construction on our new home, we started talking about stand-by generators. Our builder, Earl Weaver Contractors LLC, did a fantastic job of not only building our home, but helping us pick the right fit of generators for us. Since installation, our power has dropped off roughly 6 times. But with the generator, we haven’t missed a beat. We chose a 20 kw Guardian series and it will serve our needs for years to come. Yes, I recommend this dealer.
