Wanted to give a shoutout to Oscar and the team at Duncklee. They helped us so much with our mini splits install and really got creative in their solutions. The end product turned out great. The communication through the project was much appreciated from Paige. Looking forward to finishing the rebate process and the heating in our bedroom!

Jon and his team, Dan, Malcolm and Noah, were extremely responsive and professional. We were in a bind with a failed HVAC system and the cold weather was starting to set in. One call to Jon got everything moving very quickly. In a short period of time our new system was installed. If you want professional service, Jon Duncklee is serious about customer service, good quality products and employees that match his values.Jim and Patti

Oscar and Fernando were amazing installers. They were very professional and careful. Could not be more happy with their service. Also Paige was my salesperson and she did a fantastic job explaining everything in easy to understand terms and figuring out what I really needed for my house.

Big fan of the team at Duncklee. John was great to work with up front, helping to spec out a system that met my needs. He communicated well and followed up with everything he said he would.The install team of Oscar and Fernando were excellent as well. They made quick work of the job, communicating what was happening, and were always on time and schedule.The whole team was professional and the job was done efficiently. I’m very happy with my new ductless system! Would definitely recommend.

Duncklee's heating and cooling is an excellent company to deal with. John Duncklee was a pleasure to work with. He answered all our questions and helped us chose what we needed. His crew quickly installed the units in two days. Oscar and Fernando were very professional, courteous, timely and knew what they needed to do. They left our home spotless and took all the time we needed to understand how to safely and efficiently operate the system. I would definitely recommend Duncklee for you heating and cooling concerns.

A well run company with happy capable employees. Just when I needed it Duncklee Heating & Cooling restored my faith and trust in human beings! It is a treat to experience an employer who respects their employees and in turn the employees respect the employer. It is obvious they love what they do because they do it well. From the customer's perspective these folks are highly recommended.

Incredible service. Jonathan walked me through the entire process of getting our new furnace and a/c installed. He’s incredibly thorough and timely in his responses. I had so many questions and he was able to answer all of them and help me make the best decision for my house! Would highly recommend!

My 40+ year old furnace wouldn't heat the house when I started it this fall. Duncklee Cooling & Heating provided a reasonable estimate, and replaced my old furnace with a new Thermo Pride unit. The installation technicians arrived on time and performed a prompt installation. The furnace works great with no issues. Duncklee was great to work with. I would definitely recommend this company for heating and cooling services.

Excellent experience with sales and installation crew of my Mitsubishi Hyper Heat system. The installation crew even answered all my questions (and I had a LOT of questions) during installation. Finished system looks and performs better than expected. Would highly recommend Duncklee.Edit 11/4/22: Unfortunately I must update this review. The brief summary is that I made the wrong choice going with a Hyper-Heat system. I should have chosen a more basic system that did not require a branch box, and just continued to use the wood stove when it got really cold. Anyway, the full story is the system was installed on January of 2020. In December of 2020 I noticed a leak coming from the branch box. Duncklee diagnosed it as an issue with one of their connections to the branch box and fixed the problem at no cost to me. Roughly 20 months later, the system wasnn't cooling well during heat waves and I noticed a leak from the branch box again, similar to the first. This time Duncklee determines that there was an internal failure in the branch box itself. The branch box was covered under warranty, but the labor to remove/install it was not. I knew this was going to be a cost to me, so was not surprised. I was, however, surprised that all 20 pounds of coolant had to be replaced. That came to roughly $1,650! When the system was brought back online, the tech did a quick check to make sure it was working. We both took IR temp readings of the interior unit coils, and both got readings between 55 and 60 degrees. He said that was fine, even though I couldn't see how that could possibly cool effectively. But I'm not a HVAC tech, so I took him at his word. So the first warranty repair came to $3,150... About 4 weeks later the system isn't working well again, so they send out a different tech to diagnose. He determines that the compressor has failed. Part of his determination came from him getting readings of the coils operating between 55 and 60 degrees. He says they should be 35-40 degrees... So he puts in an order to replace the compressor. The following week they tell me that the compressor won't be in until mid-November at earliest. Not a big deal because things have cooled off for the season. Get a call today telling me that the compressor won't ship from the factory until late December, meaning I'll be lucky to have the system operating by late January. This warranty repair will cost me $850 in labor and most likely another $1650 in coolant. Meanwhile I now have to acquire a woodstove and about 3 cords of wood to heat my home from now until then. So that's another cost I'm taking on because of this system. So in summary, other than the first tech giving me incorrect info about coil temp operating ranges, Duncklee has been very good to deal with. It's the Hyper-heat system and it's branch box that I can't warn people enough about. When they work, they are great. But when they fail, the costs will eat up years of savings that this system has over other systems. I will have put more than $5,500 into warranty repairs when this is done. That will take 7 to 10 YEARS to recover in heating cost savings, assuming there are no further failures during that time.

Had the pleasure working with Johnathan Duncklee to purchase our A/C Split Unit. Johnathan came out to our home to discuss options and the process of the installation. He was very polite, knowledgable and efficient. Highly recommend Duncklee Heating & Cooling and the entire team.

Jonathan Duncklee and his crew are too notch. I purchased a Mitsubishi mini split system from Duncklee Heating and plumbing and I could not have asked for a more stress free contractor experience. The installers were so neat, they left absolutely no sign that they had ever been there other than the installed equipment. The lead installer Jim was super nice and very friendly. He answered all of my questions with a smile and left me feeling very comfortable with the entire job. I strongly recommend them!

We had Jon Duncklee over for a consultation for our future heating and cooling system as we switch away from oil. He gave us several options, and explained the pros and cons of each in a way that was very easy to understand. The company has been around for a long time and has a great reputation, and I can easily understand why.

Duncklee Cooling & Heating did a quality and professional job on installing our Ductless heating and cooling system. Our sales representative, Paige Remmert was knowledgeable, professional, and friendly. She listened to our needs and coordinated the job. Paige organized the rebates through the town which other companies would not. I would highly recommend them.

We used Dunklee to install split ac units in our 140 year old home,. My only question is "why did we wait so long?"! Paige our Sales Consultant was so professional and knowledgeable, the installation was seamless and my family is enjoying a cool oasis from the summer heat.

Not often enough do we receive praise for a job extremely well done……For 6 years I have battled the heat waves in the most important rooms in the main house namely my bedroom and study and the dining room and kitchen. The system you designed and installed works perfectly and is quiet and unobtrusive. Your lead engineer, and his assistant were professional and thoughtful, and his tutorial on how to use the remotes was concise and complete.Thanks for everything, we will be spreading the good word on a difficult job well done!

The team at Dunklee designed and installed my home HVAC system nearly 20 years ago and has been there with sound advice and great service since then. Their field technicians are top notch. Not only are they experienced and knowledgeable, but I’ve always found them to be friendly and informative.

Jonathan was able to start our estimate prior to onsite visit and provide options/quotes upon home visit. Our home is older split level and partial flat roof. Jason and his install team arrived on time, were positive re. the project challenges, communicated daily and cleaned up behind!

Stephen Castagnaro

I was a little disappointed in the amount of legwork I had to do , specifically I had to go before the Historical Commision twice to get their signoff and I had to go to the townhall to pay the permit, hence the 4 stars. To be fair I do not believe they are the only contracters that leave this to their customers although a neighbor did not have to deal with this for her recent HVAC install.However I could not be more impressed with the professionalism and competence of the installation crew of Noah and Jason as they addressed the challenges of installing on an older home and having to adjust the original installation specs. Their communications relevent to their progress and our endless questions were outstanding. Highly recommended.

Using Duncklee was absolutely fantastic! Jon was so professional as well as personable. He walked me through the entire process and although we had some hoops to jump through as this was for our 2nd home, he was very accommodating. The only note that I had was that I didn't know we needed to hire an electrician until the day we needed one. If I had known earlier in the process I could have coordinated and scheduled accordingly. Luckily one was available and get the work done in a timely manner. We really enjoyed our experience with Duncklee.

*update 05/23/23. Tech called us to take payment and computer didn't work when I tried to pay. Then my wife tried to pay and they tried to take payment from my wife which they inputted numbers wrong. Due to my bad review they posted my personal email, cell phone number and address. We will pay this tomorrow but completely can't believe you would air out your CUSTOMERS PERSONAL information from your database on a public website. This is personal identifiable information that they are willingly putting out for others to contact. We will pay tomorrow if your company can put the numbers in correctly.ANYONE USING THIS COMPANY BE CAUTIOUS AS THEY EXPECT YOU TO ASK SERVICE CALL Prices AND IF YOU DONT THEY BLAME YOU AND THEN PUT YOUR INFORMATION OUT. THEY PUBLICLY DISCLOSED MY PERSONAL CONTACT INFORMATION WITHOUT MY Consent.Originally the company was greatWell 2 years later I have a split system that needs work and I called them to to service the system cause it wasn't working right. After quick troubleshooting and for an hour of work he gives me a 292.00 bill. Because I reset the system there were no longer error codes so I literally paid 292 dollars for a professional to tell me it's fine call back if you need anything. Won't use them again. Not even sure how to use warranty at this point.Call around if you want an honest company

CAREFUL using this company they will share ALL your private information publicly. Name, address, phone number, ectWe had Dunklee service our system. We were caught off guard with how high the price per hour was. So we made a review to inform the public about this. Dunklee response to our comment was sharing our private information. I will not trust them again and am scared for my family now that people have full access to our personal information.

Beware of this company ! I had the misfortune of giving DUNCKLEE HVACa try, big mistake. I've been working with contractors for years never experienced such poor customer service. I called to have this company give me a quote on a new heat pump and air handler. OWNER REFUSED TO COME OUT AND EVALUATE MY HOUSE SAID HE DID ONE ALL THE SAME. THE DAY HIS CREW CAME OUT THEY INSTALLED THE UNITS, TOLD ME THERE WAS A LEAK IN MY LINE SET, COULDN'T DO ANYMORE. THEY ASKED TO GET PAID, SAID THEIR JOB WAS DONE. THEY WERE MORE INTERESTED IN GETTING TO A SOFTBALL GAME. I TRIED TO REACH THE OWNER, HE WOULD NEVER ANSWER THE PHONE. HE HAS HIS OFFICE STAFF SCREEN HIS CALLS AND REFUSED TO CALL ME BACK. ONCE THEY HAD MY MONEY THEY COULD CARE LESS. THIS COMPANY WANTS QUICK IN AND OUT JOBS THAT DONT REQUIRE AND THINKING. I SHOULD HAVE KNOWN BETTER WHEN SHETUCKET PLUMBING WARNED ME NOT TO USE THEM. IF YOUR THINKING OF USING THIS COMPANY THINK AGAIN! I am shocked he's still in business!

I submitted an internet inquiry and have left two messages at the office to have someone contact me for a new heating/AC unit at my home in Stonington. No one has responded. I reached out to two other companies who called me back same day and had quotes to me within two days. To make matters worse when I inquired online it must have added me to their email list so now I get spam mail from them when they couldn’t bother to call me back….
