Because of his knowledge, we decided to go with a new heater. He helped us get financing quickly and it was installed by two awesome techs he has. They were so considerate, putting down tarps so they wouldn't damage the floor as they came in and out. At one point, the tech redid all the wiring so it would "look cleaner". They were so nice and quick. Cleaned up everything before they left. I would highly recommend Jack.

My sister bought a house outside of Princeton in 2023. Prior to the sale, the owner had Condon…read moreTotal Comfort install ductwork through the second floor to the attic in order to get AC and heat to the upstairs bedrooms. As a general contractor with over 20 years in business, I was not impressed with their work. They ripped out whatever was in their way and left a mess that had to be fixed/covered up. In one instance, they only needed a couple inches and they could have installed the duct behind a closet wall/bi-fold door but instead they busted up the trim and tore out framing to do their install directly in the way of the door. I understand that the owner who was selling the house probably didn't care - they likely just wanted the "cheapest" thing done to get the sale, but it showed a distinct lack of foresight AND a lack of respect for the new owners (my sister, brother-in-law and their kids). It really isn't THAT much more difficult to CARE about one's work! Based on that, I cannot recommend them.

Called for service on my leaking well cap. I explained the issue over the phone and they said,…read more"Yes, we can fix that." So I setup an appointment. When the guy gets to my house I show him the leaking well cap and my questions were, "Is it supposed to do that? How does it need to be fixed?" His exact answer was, "I don't know". I explained the issue over the phone for this exact reason!!! Since I was already paying the service fee for him to come out to my house, and he wasn't able to fix my real issue, I thought I might as well have him replace my sink drain. He replaced my sink drain and as he was leaving he specifically said, "I'll figure out what needs to be done about the well cap issue, so we'll get back to you." I never heard from him or the plumbing company again except for a bill in the mail for the sink drain and service fee which totalled over $100.00 for a single sink drain!!! I called them with a specific issue that they said they could resolve. They didn't even question it. Automatically said, "Yep, we can fix that". Not only was it misleading when they told me they could fix my well cap issue, they completely lied when they said they would figure out what needs to be done and get back to me. I was expecting them to hold true to their word, like a normal good standing business would do. That never happened until I finally gave up and called a real plumbing company that was actually able to help me. Let me repeat that...I never heard back from them again except for a bill in the mail. They lied about being able to fix my issue only to get the service appointment. Then lied again when they said they would figure out what needs to be done and get back to me. Koch is the worst plumbing company I have ever dealt with!!!
