Dupont Heating & Air Conditioning Ltd

Over-sized our furnace by 50%. Company supposedly is a Carrier dealer but claimed to have no idea there was a legal settlement due to a class action lawsuit of 200,000 Canadians resulting in rebates to customers. Charges $169 as a "warranty labour rate" vs its regular rate of $99/hour, meaning the homeowner gets zero benefit due to "free" warranty parts because the homeowner is charged almost double the labour costs to have them installed, and may even end up paying more than without a warranty.
Jackie - their front office person - is remarkably uninformed and has a lack of diplomacy that together suggest she shouldn't be speaking with customers.

Did a great job with my furnace replacement. They had good prices and good service. I would use them again in the future. Watch out for the scammers in this business I had a few questionable quotes from other companies.

Our 7 year old furnace was producing a burning smell and weird noises so we had to shut it off. We called Dupont after the first company we approached failed to return our calls within 5 hours. Dupont provided us an appointment time for the same day and arrived early portion of the appointment window. The technican was knowledgeable and courteous - and worked really quickly to identify the problem.
Pricing to fix the problem was provided up front.
The first replacement part (located and installed later in the same day) was faulty, but the technian was able to hook up our system so that we could have heating in the interim. A new replacement part was located and installed on the next day during hours that were convenient to us (a bonus!). The technican even provided us with information on how to maintain our heating and AC system AND identified and fixed a small peripheral issue that was resulting in suboptiminal heating performance.

We will definitley consider Dupont Heating and Air Conditioning for our future heating and air conditioning needs.

We just moved in to our place a few months ago, we noticed that our heat was minimal on our upper floors so we had DuPont come out to check that all the duct connection were Ok.

The person who came out was friendly but I was annoyed that he asked me to go and buy a tube of clear color high heat silicon because he only had red color silicon. At the end of the day I didn’t think that he did a whole lot for charging me for 1 hour work and there is only a marginal difference in the heat on our upper floor.

Having recently purchased an old home in Toronto, we knew that work needed to be done. Part of that was getting the AC unit checked-out as it was leaking. I called Dupont as they were the company's who's named was attached to the new furnace in our home. The technician came & detailed that they installed the new Furnace, but the AC unit was leaking onto the new furnace. We were told not to use the AC at all until the leaking evaporator coil was replaced, in order to ensure it did not leak onto the furnace and do any damage. In the middle of a hot August summer, it was hard not to use the AC, but Dupont came in with the part within 72 hours and arranged a quick Saturday appointment for installation. Before I knew it, the problem was fixed & they took time to show me what was done and how to test their work. The AC unit worked perfect since, and no leaks. I am considering calling them for additional work we need done shortly on our duct work.

Found them on homestars. Scheduled a service call and they actually showed up earlier than planned (bonus points there). The technician noticed the service valves were toast so the options are to replace the vales or replace the unit...we'll probably replace the unit. The only down side was they still charged the full service fee for a 2 minute job. They said if we buy through them we get refunded but I feel if they gave a discount upfront, it would make doing business with them again easier. Probably will bring them in for an estimate but seeing how they are using the refund as bait, I'm not sure if that leaves a good impression.

Recently we purchased a new home in the Lawrence/ Avenue Rd. area.
The house being rather large we found the airconditioner was not able to adeequately cool the entire house properly. On the advise of Dupont Heating & Air Conditioning we installed an airconditioner in the master bedroom and now we can sleep cool and comfortable all summer long.

Recently purchased and had installed a new furnace with humidier. Pat came out to give me a quote and was very knowledgeable and professional. He took the time to explain in detail the equipment and how it worked. The installation crew from Dupont was on time as promised. Their installation crew was very courteous and neat. The installation was done efficiently with no mess left behind. The overall experience was wonderful from the time I called to book an appointment right up to the completion of the install. I would highly recommend this company to everyone! Life long customer of Dupont Heating!!

We hired Dupont to purchase and install an AC unit & humidifier to our forced air system. They promised us that we would get a $50 rebate on the AC unit. However, the manufacturer did not want to honour that, and it was an ongoing issue. Then, a month after the installation, the water connection to the humidifier broke while I was in the hospital. We got home from the hospital to find 1/3 of our basement flooded. They came and fixed the connection. On the rebate issue, Dupont finally did help us get the rebate. I felt I really had to pressure them to live up to this part of their commitment to us. $50 is a small amount on a $4,000 job, but they might have been more helpful about it - especially as we never sought damages for the water damage done as a result of the poor connection to the humidifier.

We had just moved into our house and the furnace was not working. The team at Dupont was great! Withing 2hrs of calling a service technicial was by to look at the problem, and 2hrs after that we had a quote and an install date set. They were professional and very knowledgeable, also helping us to take advantage of the various government grants and rebates avialable. They even dropped off space heaters to give us some heat until the new furnace could be installed.
