"First, they were recommended to us for the whole house generator by home depot. We were so happy with the generator that we had him do a bathroom fan at my house and a bathroom fan at my son's house. I did some checking and that was a reasonable price. With the work he did, it was more than reasonable. The job was a little more involved than he thought it would be and he didn't have any problem with any of it. Without anything to judge the pricing from, other than online and a couple of guys I had come over who weren't on the same page as me, I'd say excellent. The quality was top of the line. As soon as he got the generator, he got over here to put it in. As a matter of fact, I am thinking about calling him again for something."
