Dupont Heating & Air Conditioning Ltd

Used this company based on the excellent ratings it received on this site. The gas stove installation was done right with the technician being fast, courteous and considerate enough to show me all the details of his work. I recommend them highly and already have booked an appointment with the firm for my annual furnace maintenance.

We recently purchased a new Carrie Infinity ultra high efficiency furnace from Dupont. Pat's in home consultation was excellent. He didn't try to sell us more than we needed and pointed out a few problem areas with our return ducting.

Mario and his team showed up on the Friday of a long weekend. They had to rip out the old furnace, do some duct work elsewhere in the house, install piping to our gas dryer, hook up a gas stove and install a new hot water heater. Most of the work was done in a very small space on a very hot day. They worked til 8pm. Mario then stayed and took another 45 minutes to explain how to use and maintain all the gas appliances. All this on a long weekend.

Well done Dupont. I wouldn't hesitate to recommend them.

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.

When I called Dupont Heating they scheduled and in-house free of charge quote immediately. Pat came to my house and gave me a very educational info session on Carrier air conditioners and furnaces. I was extermely grateful for all the info since it allowed me to make an educated decision as to which units I was going to purchase. Other companies gave me quotes over the phone (not in writing) or never described exactly which units they were going to install. The following week the Dupont Heating installers came to my house at 8:30 am promptly. Mario, Sam and Samy installed my air conditioner and furnace quickly and neatly. They went above and beyond their responsibility by reinstalling some exhaust pipes to allow for more headroom in my furnace room. I would highly recommend Dupont Heating to anyone who needs a new air conditioner or furnace. THANKS GUYS!

We had to have Dupont in to fix an issue with our boiler just as the temperatures outside started to drop. They made themselves available for us and were prompt and polite, fixing the boiler and agreeing to come back for a complete cleaning/service in the following days. We will use them from now on.
