Dupont Heating & Air Conditioning Ltd

I cannot recall exactly what we were charged and they never sent an invoice as they said they would.

What I do remember is that when I checked the what an igniter installed should cost I saw that they had charged a inordinate amount.

The fact that they overcharged and failed to send an invoice puts this company in the bad bad bad books.

I would like to share my experience with Dupont Heating & Air Conditioning.
We went for one week vacation and when we've came back to our horror our house was cold. We have realized that there is something wrong with our furnace. It was late Saturday night!
I've called Dupont Heating & Air Conditioning and left a message. Right away I've received a call back from Mario, who tried to help me over the phone to see if we can fix the problem. I was really appreciative of him taking the time and trying to resolve the issue. Unfortunately, I was not able to fix the problem. Mario got into his car and showed up at my house at midnight! I was so relived to see him, as I was dreading the cold night in the freezing house with two little kids. Mario was very professional, knowledgable and caring! For Mario it wasn't important to charge me extra for late night weekend visit, but to make sure that our furnace was up and running! I was so grateful to him and relived to have the warm house again!

After that we've done the maintenance of our furnace with Dupont Heating & Air Conditioning. Hameed, who came to our house, was also very professional and very precise. He checked every detail and took his time to do his job. Job well done!
(BTW we've done furnace cleaning before the winter with different company and with my own eyes I've saw now that they never cleaned the vents or other parts....it was a joke!) I wish I've found Dupont Heating & Air Conditioning sooner...

Now, knowing that there is Dupont Heating & Air Conditioning I have a peace of mind, as I know that if there is something wrong I can call them and they will be there for our family! They provide a service 24/7 and they mean it!

I had an old roof furnace that was electric and Dupont Heating took it off in the rain and installed a new high efficiency gas furnace.
Mario is a gem to work with and his staff are great. I would definitely use them again.

We had a Carrier gas furnace installed a couple of years ago, and are writing now to share the positive experience we've had with Dupont Heating and owner Mario. Despite what other customers may have experienced, we've personally have had an excellent experience with Dupont Heating, and would recommend them without hesitation. We are very happy to have upgraded our gas furnace unit to a high efficiency unit. What makes Dupont Heating stand out from other heating companies is their post-sales customer service. They have a 24/7 customer service helpline, and it is reassuring to know that you can always speak to someone from the company if you have any concerns you may have. Whenever we had any questions about the operation of our heating unit, or any other HVAC related questions, Mario always responded very quickly and professionally - even showing up to our home when needed. We have found that their team are a dedicated group who are more than willing to answer questions and provide help however they can. They stand behind their products and provide excellent service. We would recommend Dupont to anyone looking for a gas furnace and excellent customer service!

I called DuPont. Their receptionist Nicole took my call. She was very helpful but it seemed there weren't any available service reps to come immediately (we had no heat and its -20 today) Nicole said she had a solution. Louie one of the owners came out to us personally. Louie was at my door in 15min. Identified our minor furnace issue in minutes.
Charged us the minimum service charge!!! We have heat. This all in less than an hour since I first made the call. Unreal. Thank-you DuPont!!

Dupont Heating and Air Conditioning installed my furnace, air conditioner, A-coil and pipes, and humidifier 2 years ago. I bought a Carrier system at a good price. The installers were courteous, tidy and got the job done in one day! Just recently, the owner, Mario, came quickly on a cold night when my furnace was acting up and fixed the problem pronto. The service is great, personal and well-priced. Dupont is right in my own community and serves its community well - much better service than a "big box" or national chain would provide. I highly recommend them.

I have been using Dupont since 2004. I recently had a problem with my water heater and they did an AMAZING job. Their service is impeccable and they are very responsive. I would highly recommend them vs. the big box options.

From my first contact with Nicole in the office to Mario's service visit to the techs Danny and Sam we could not be more thrilled with Dupont! A nightmare carbon monoxide problem was resolved quickly and competently. The pricing was fair and matched our initial quote (which was very comparable to competitor's pricing). The installation was completed in a smooth and timely manner with minimal mess and inconvenience. We would not hesitate to recommend Dupont for any and all heating and air conditioning services. Bravo, you guys!!!

This is a long but very true story; worth the read if you're considering hiring Dupont. DO NOT! TURN AND RUN!

Full credit to Dupont for the worst customer experience in my life. I would give them -10 instead of zero if I could.

I bought two ductless AC units from Dupont years ago because I really liked Mario; he's warm, friendly, and very knowledgeable. Too bad he's not involved on the service side. I've made the mistake of hiring them to service the units since then and have had problem after problem (service issues, overcharging, misleading on costs, being unprepared, etc.), but this recent event takes the cake. I hired them to disconnect two AC units sitting on the ground so I could have new cement put down.

When the disconnecting was done, we had a disagreement on the bill…once again Dupont hadn’t told the serviceman I was getting a discount to compensate for a prior problem. I invited him into my house so we could call Jackie. Big mistake. The discussion became an argument, and he got so angry, he yelled and hovered over me.

I told him several times to get out of my house, I said I would call the police, that I felt physically threatened, but he refused to step outside the door! He just stared at me wide-eyed, hovering over me in a menacing way, huffing and puffing. I had Jackie at Dupont on the phone and asked her to tell him to leave, hoping he would listen. “Do you hear this, Jackie? Do you hear him refusing to leave?” She said “yes, I hear him" but didn't ask to speak to him, didn't try to deal with this.

I finally defused the situation myself without getting punched by a Dupont serviceman who probably weighs 100 lbs more than me. And remember, I’ve bought two AC units from these people! This is how they treat repeat customers of big-ticket items??

I hired a different company to do the reconnection and will never work with Dupont again. The new guy showed me several mistakes Dupont made (cutting the pipes improperly and not draining the refrigerants properly), which also means I overpaid Dupont and that it cost me extra to reconnect the units!

Mario is great, but the rest of the staff…from bad to worse to nearly violent! Frank means well, but he’s very inconsistent and doesn’t prepare the technicians who do the work, leading to confusion and poor service. And Jackie clearly couldn’t care less.

Spare yourself the missed work, the confusion, the terrible service, and feeling physically threatened from a certain unnamed bully of a serviceman. Go with someone else, ANYONE else than Dupont.

I'm committed to doing the best I can in an urban environment to avoid excessive resource use. I have been a Dupont client for more years than I care to share, but I contacted them recently proposing a change to a tankless, gas-powered water heater. They did a great job of explaining my options, offering two manufacturers' solutions, organizing the process, and operating the install with a high degree of sensitivity to minimizing upset. I chose the higher-end manufacturer, Rinnai, because all parts are replaceable, and because of their many years of good reputation. The removal of the old water heater was handled impeccably. I am already observing the reduction in electric power and of course in billing, and the new gas charges still keep me in a net win position. The overall payback will take a few years, but it was the right thing to do! Well done, Dupont, and well done, me! A win-win!
