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.

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.

It takes 5 phone calls to get anything done because all I get is the stupid AI rep who can't solve any problems.

I'm wondering if they are not hiring people to answer phones (or worse - letting people go) because all I get is the AI rep.

They told me they were 99% sure what it was based off how I described the operation and, unfortunately, I'd most likely need a new furnace. But they would send someone out next day to make sure since it was getting cold out. They came out next day and ran through the test with me, explaining what was wrong. We determined I did need a new furnace, why my current one couldn't be repaired, talked options and made an order. They were back out the next week, in peek season, to install my new furnace. I had Heat just in time for the cold snap. Everyone I dealt with was professional and honest and I was so impressed I chose them to do all the heating and cooling work on my new construction the following year. I see negative reviews and cannot even imagine that these are the same people I dealt with.
