Dupont Heating & Air Conditioning Ltd

Terrific technicians in DEE and David. On site visit by supervisor Mario. Terrific service in moving our hot water tank, furnace and getting all of our heating and AC needs up to code. Using them since 1999 and very thankful! George Barron, Beaconsfield Avenue

After reading all the reviews here about Dupont, I decided to call them to fix my furnace problem in this cold winter day. I was so happy for this decision. They came and fixed the problem very quickly and gave us very good advice. And the service price was quite reasonable. They also gave very competitive price for replacing the furnace later.

I'll definitely choose Dupont always and will recommend them to my friends.

I had priced like 10 different contractors for full HVAC and partial duct replacement in my house and their price seemed to me the most fair for Carrier 95 furnace and Keeprite 14.5 conditioner.
The job is done and after a few months i have nothing to complain about, everything works plus i already received government rebate Dupont applied on my behalf.

We have ductless air conditioners one of which had a faulty pump and a lost remote. We called Dupont who were supposed to know how to deal with our brand. The worker came with the required remote but didn't realize it needed batteries so went to a nearby store to buy them. He also didn't realize that one remote would work on all identical units. He looked at the ACs and said the filters needed cleaning - he handed them to me and I washed them. He told my husband to wash the condensing units outside. He didn't touch the pumps at all. He charged $200 for the remote and $99 for the 'service' call. When I called (3 times) to ask for further service (the $99 was supposed to be for 3 months) the company was very polite but never called back. I got someone else to replace the pump and do the required maintenance at considerable expense (this worker told me that the pump maintenance was a regular part of a service call).

After receiving quotes from a number of companies for a high efficiency furnace, I was very happy that I decided to go with Dupont Heating. Their prices were much more reasonable, and even more importantly, they didn't try to upsell me or lay on the gimmicks. The man who gave me the quote was straight-forward and easy to talk to. The install crew was excellent and all my dealings with the company have been equally as good. I highly recommend Dupont Heating and Cooling!

Dupont did a great job with some small but complicated jobs around my house. Duct work, pipe replacement, valve replacements, and securing bathroom pipes. The also did some great work for the in-laws with a heat pump (large job). Very good firm.

Having done alot of research as to furnace mfgr's my next hurdle was finding a reliable install, which is equally important...Dupont went the xtra mile and new they're stuff, Mario provided very competitive pricing and hands on service, he addressed any issues or needs that undoubtedly come with the job..Thanks Mario...thanks Homestars...

Micheal from Dupont Heating came to clean furnace. He spent about 1/2 hour doing this. He did a check list of everything he did: thermostat operating, checked venting, piping, burners, cleaned blower and checked operating, checked heat exchanger, filters checked. and CO levels He said the furnace was working well and that I did not need a new one for a while. Very satisfield with the work.

Mike was great to deal with from the get go. I had called him almost a year ago about a potential problem but he gave me simple directions on the phone to a solution. Remembered this and the reason why I called on them again. Service technician showed up today on time and was very knowledgable. Took his time to explain the system to me and the challenges we were facing. He was very polite and respectful of our home and children. Notice a couple of issues that needed to be addressed and explained thoroughly to me. Called Mike to make arrangements for a follow up service call on the spot and to make sure any needed parts were available to get the job done quickly. A price for follow up work was provided on the spot while technician was on the phone with Mike. So far...very happy.

I had this company install a new gas furnace. Work was completed in a timely manner and installers were very pleasant. I than contacted the company to service my slim jim air conditioner located on my roof. They booked me in and never showed up. Called to see what happened and they gave me an excuse. Rebooked and same thing happened. Tried one more time. Same deal. Called the fellow who does booking and asked what kind of service is this. He advised that their technician didn't want to get a ladder and go on the roof to service the air con. I guess they must have too much business when they treat their customers like this, and after paying for a new furnace. Called their competitor, [ed- competitor removed] who where happy to do the job and now service my furnace as well.
