“Initially when someone came out to look at it, I guess the incorrect information was provided to the technician. Because of that, not all of the parts were in the van. It had to be a special connection, that I didn't know to tell them. Then, there was an issue getting it to work because the power went out just as the installer came. I have a newborn at home, and he went above and beyond to make sure the water heater got connected even though there was no power due to a storm.”

“I feel the company exceeded my expectations in that I asked a lot of questions, and they gave me a lot of information to think about. That was good.”

“All areas except when I had to buy the HVAC system, so the sales. They have been professional, very courteous and take the time to explain things to me since I am technically challenged.”

“Everybody was wonderful. I had a plumbing problem on Super Bowl Sunday and I am 30 miles from Philadelphia and I didn't think I could get anyone to come out. It was snowing, sleeting, and raining. They came right out and it took them a few days since the job was more than they thought it would be. I live out in the country and there is no public water or sewer. They were very honest and told me everything that was going to happen. They got the job done and put grass seed down where they had to dig the yard up.”

“Explaining the scope of work exceeded my expectations.”

“I was most satisfied with their timeliness.”
