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.

Very poor on communication, will not return email requests. Will call and schedule a day then not…read moreshow up. We have been asking for a year to please come out and stop the banging noises in our ducts, it is absolute torture at night to listen to. They came out once, hit the duct with his fist and called it good. It has gotten worse with time I have 6 emails to them to please fix it, no response. Now we are reaching out to other companies to see if they can fix it, litigation will follow if there is a cost. this is not the way to treat someone when they spend a lot of money on a new HVAC system.

He was able to order both motors from the supply house fix the furnace. I was told the furnace has parts that can be ordered and that the parts were not obsolete. I would not recommend OshKosh heating and cooling to anyone. I feel I was lied to to try to sell a new furnace when the gentleman came in to look over our furnace, he said that 21 year old Furnace. Furnace was at the end of its life expectancy. However, when the other gentleman came and looked at the furnace, he told us the furnace is built to last 30 to 40 years and parts are obtainable. All Lenox furnaces have parts that are obtainable from a wholesale house I was completely put out by this conduct I would not recommend Oshkosh heating cooling to anyone.

Most importantly, our transfer switch was working perfectly until Kollmann came and rewired it and fried our coil. Now they refuse to pay for something that they broke. They billed us and are now expecting us to pay for an incomplete job and left us with an nonworking unit. Their employees were also playing pool on our pool table while they should've been working.
