We recently got Dupont Heating and A/C to install two air conditioners and one new high efficiency furnace in our houise. The installation was somewhat complicated. We were worried about this install because we had some other mechanical contractor do some other work on the house which did not go well. Pat came and met with us. He was very professional. He came up with some sound solutions, was very confident in the abilities of his crew, gave us a written estimate and clearly explained what they would install and how. He made us feel at ease. Their pricing was very reasonable from our experience. The crew arrived as was scheduled, Mario listened to my initial concerns regarding aesthetics and they delivered. Mario and Vito worked very hard. They went that extra step to ensure that the work was done properly. They even fixed a number of items that were incorrectly installed by my previous mechanical contractor at no additional charge. We are both Architects. We work with mechanical contractors all the time. We rarely find a mechanical contractor that tries to see the whole picture and takes pride in those little details that so many other mechanical contractors do not care about. Dupont is one such contractor. We would have no reservation in recomending Dupont to anyone requiring heating and air conditioning work. We will also pass on the same recomendation to our clients in the future. Thank You Pat, Mario, and Vito.
