I've also used Action--they…read morewere terrible in comparison. 1st call to Cardinal was in a panic with the sudden loss of AC in a 90 degree day. 5 animals in the home. The person with whom I spoke understood how dangerous of a situation this was and a service person was scheduled that day. 2nd call was for electrical work--not urgent but they happened to be able to squeeze me in on the same day which was probably rare but amazing! Best parts of this experience: 1. Friendly and empathic front team who got me scheduled ASAP. 2. Text prior to the service person's arrival with their pic and some info to help personalize this 'stranger' 3. The service people themselves--extremely competent, focused, and very personable. I only wish they serviced commercial properties so I could have them out to my business!

No way was the…read moreamount of work I was estimating worth the same às a slightly used car! $9k for what is probably 2-3h work is laughable!!! This makes me wonder what they are charging other people who haven't researched the things they want to the same degree I have. It's almost criminal. Their estimator was very pleasant, though. And their communication is quite good. Maybe that's where the extra $5k is required!!!.... Complete BS

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.

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.

The Grenz folks came, carefully looked at the unit, and said, "If it were my furnace, I wouldn't do anything. It is running the way it's supposed to." This second opinion cost me something, naturally, but it also saved me between $5,500 and $19,500 (two quotes from the other two companies). Jim seems like a straight shooter. I'd recommend you give these folks a try.

I've worked with Andy's several times -- Kevin, who may be the only guy? -- and he's great. He…read moreclearly loves solving problems and I really get the impression he's honest. The first time our furnace was leaking water. He fixed it for not much money (I don't remember how much), warned us if it happened again we'd probably have to replace it, and that was like a year or more ago. All has been fine. The second time was the first really hot day of the year. Our AC stopped working. He came out right away, did a great, fast, and very competent job, and fixed our problem for $200. I trust this guy.

There was a listing for Barnard Heating & Cooling (Nathan Barnard), which started business in 2024 and he stated he has 13 years' experience in HVAC and he was open on Thanksgiving Day; so, I called him and explained the situation. He said he would take a look at it on Friday, the following day. He checked it out, knowing that I needed a new furnace, he said he could install a new Heil furnace the following Monday and quoted a fair price. I told him to write it up. So, Monday, he installed the new furnace with no problems. What a difference; heats the house quickly. Nathan "Nate" Barnard is very professional and personable. The absolutely the best contractor I have ever worked with. I highly recommend Barnard Heating & Cooling. Way to go, Nate. 5 stars. Gary P.
