Louie the owner installed a new high efficiency furnace in my house. His crew did an excellent job in the installation and gave me a price significantly lower than other quotes I received. I've saved a ton of money on my heating bills. Louie was professional, courteous, and extremely knowledgeable. 10 stars without hesitation.

Yes, I would recommend this company to my mother. In fact, when my elderly parents' AC conked this past summer, my father insisted that I call Mario at Dupont. He had done service work at their house before (replace furnace humidifier and tune-ups on their ancient furnace), and they were very happy with the personal care received. The AC was installed within 2 days, nice clean job. The service technician took the time to explain how to maximize the component's efficiency and extend its life. Absolutely no complaints.

I chose Dupont to install a new high- efficiency gas furnace and humidifier after comparison with other contractors, based on the total heating solution offered with compatibility for future HVAC enhancements (e.g. tankless water heater, air conditioning), product line (Carrier), pricing and job scheduling. The work was completed efficiently and on time, including duct work, new venting, new thermostat, provision of a chimney liner to ensure that the existing hot water tank would operate properly alongside the new furnace, and removal and disposal of the old furnace. The Dupont service technicians were professional and courteous, finished the job in one day, and left the new furnace area clean and free of debris. Dupont also arranged for the application of the government rebate and registration of the new furnace and humidifier to the product company so that the warranties would be in effect. Altogether, Dupont delivered excellent services under this contract.

We recently moved into our house and noticed a faint smell of gas in our basement. Enbridge arrived and confirmed the gas leak, shut off the gas but due to their company policy were not able to fix the pipe. We noticed that Dupont Heating & Air had installed a new furnace with the previous owner and we decided to contact them. Mario assessed our situation immediately, gave us a quote and assigned someone to replace a section of our pipe the next day. Thanks for making our home safe for us again!

MY AC went down just before the July long weekend. I got it going again myself, but it struggling to keep up and considering it was 14 or so yrs old it was time to change it out. I emailed Mario late in the evening with the specs of the current unit, size of house and he got back to me with his suggestions right away. I did a price check and his price was fair and it was a quality Carrier unit. The team came two days later to install. Clean install and same team that did a combination hot water for me at a condo last fall. Mario and team did a great job and was fair on a previous job so I used them again this time. I plan to use them in the future and would highly recommend

This was a big job. We had another quote for this project but their's came in under and for better parts. They had to remove all of our existing pipes and replace it with flexible pex pipe. The job was done really well. It did need a service call to adjust once the cold weather came as we did the job in July. They were prompt and really considerate and fixed the noise that was coming from the new system as it just needed tweeking. I would definitely call on them again.

We had our furnance and air conditioner installed by Dupont last fall, We found the team under Mario's direction to be extremely professional. The heating system worked beautifully during the winter. This spring we discovered that the air conditioner was not functioning correctly and failed totally on the hottest day this May. Mario arranged for a Saturday visit by the first technician but no success so the office send Eric :) to be that second set of eyes. Eric was fantastic he went right to work and problem solved, in short our air conditioner was repaired. Eric's knowledge of systems is uncanny. Eric is an amazing technician who really knows his stuff. Well done and thank you. Jim and Joan/Toronto

We had an amazing experience with Dupont. Our air conditioner broke down on a hot humid Saturday and we were in need of a quick replacement! Mario pulled out the stops to schedule us in as soon as possible on a Sunday afternoon so we would not need to miss work and importantly would have air conditioning ASAP. Marcus came to install our new unit and despite a complex job where he had to get access to our condo roof through another building, he was pleasant, upbeat, kind and wonderful to deal with. He worked quickly without interruption, cleaned up and was delightful to work with. Mario followed up later in the day to make sure all was ok and that everything was to our satisfaction! I could not ask for better service and would highly recommend this company!

Mario Gallo and his crew provided exemplary service. The job was done the same week, the work was impeccable. Best though was that Dupont, because of their status with Carrier, was able to "give" me an upgraded Furnace which provided an enhanced OPA rebate, so that the whole deal was cheaper and better technologically than I could have thought. I got a Lincoln for the price of a Focus. Superb, old school, relaible and responsive company. Mel Greif, Annex

I extremely disappointed with the service from this company. We had a new furnace installed just over a year ago and were told after a cleaning in January that a major part was faulty and needed to be repaired. They said it was still okay but should be done as soon as possible and the work would cost $600.00. When we contacted the company because we felt this was a large amount to pay after 1 year that the furnace was installed they agreed to reduce the cost by $150.00. An employee from Enbridge came to our location on Feb 21 and advised us that it was extremely important that the repair be done immediately as it was extremely dangerous and the funance could of blown up. We subsequently called dupont and they came to fix the problem and charged us $850.00. This was absolutely absurd. Never mind the money they put our employees and tenants in danger. When I approached them about the cost they could only say that these things happen and some other pieces were required. We used them because we like to support local businesses but are so disappointed that the owner of the company did not even try to contact us about this matter and left it up to employees to deal with. Be very careful when dealing with this company and research the products they sell.

Company Response:

Here is my response to this person's review. I've included her comments and my response to them below. We had a new furnace installed just over a year ago and were told after a cleaning in January that a major part was faulty and needed to be repaired. They said it was still okay but should be done as soon as possible and the work would cost $600.00. When we contacted the company because we felt this was a large amount to pay after 1 year that the furnace was installed they agreed to reduce the cost by $150.00. An employee from Enbridge came to our location on Feb 21 and advised us that it was extremely important that the repair be done immediately as it was extremely dangerous and the funance could of blown up. The boiler was actually installed over 2 years ago. Your warranty on this boiler expired over 1 year ago. The quote provided to you was not $600.00 but rather $450.00. We advised you that the repairs should be done as soon as possible and we spoke to Nadia a number of times to try and resolve this issue. I even offered a $50.00 discount on the repairs for the expansion tank. We subsequently called dupont and they came to fix the problem and charged us $850.00. This was absolutely absurd. Never mind the money they put our employees and tenants in danger. There was never any danger of anything blowing up. The information that the Enbridge technician gave you was incorrect. If someone from Enbridge advised you on February 21 that there was a dangerous situation there then why did you wait until February 29 in the late afternoon to call us for repairs? We first advised you of problems with your system on January 11 which was almost 2 months ago. The parts that were replaced were not part of your boiler installation. These are external controls and if you check your contract with us it shows that those items were not changed as part of the scope of work that was quoted to you. When we came out to provide you with a quote for replacing the boiler, these items were excluded at your request to keep the cost as low as possible. When I approached them about the cost they could only say that these things happen and some other pieces were required. When you called this morning you didn’t allow the person to speak and explain to you that these items were original to your boiler piping and not replaced during the installation of the new boiler. Again, when we came out to provide you with a quote for replacing the boiler, these items were excluded at your request to keep the cost as low as possible. We used them because we like to support local businesses but are so disappointed that the owner of the company did not even try to contact us about this matter and left it up to employees to deal with. The only request you made to speak to an owner was this morning in an irate phone call and he was not available to speak to you, nor were you willing to let the person on the phone respond to any of your requests and explain to you what I am writing to you now. Be very careful when dealing with this company and research the products they sell. We’ve been in business since 1964 and we have been servicing the entire GTA for years. If we treated our customers like this we would not be here today. When you first called, I went as far as re-arranging my technicians schedule to serve you right away even though we tried to address this matter earlier but received no response. The technician that came out went as far as picking up one of the parts that you needed from one of our suppliers so that your issues would be fixed right away. Both the Enbridge technician and my maintenance technician misdiagnosed the issue as being the expansion tank. When my senior technician showed up to replace the expansion tank, he re-diagnosed the issue and found it to be a faulty tridicator which was caused by a failed backflow preventor and automatic water feed valve. He fixed your problem right away and got you back up and running. What more would you have expected from the service provided?
