Duncklee installed a new high-efficiency furnace in my home, along with a smart thermostat. They did great work and were very professional and knowledgeable. And when I had questions afterwards, they responded right away and were happy to help.

Duncklee Cooling & Heating's team removed my oil furnace, electric hot water heater, and an old central A/C and installed an LP Gas furnace, LP tankless hot water heater and a new central A/C unit. Needless to say there was a LOT of work to be done, and the team (Jason, Noah and Malcolm) were the ultimate professionals! They were very knowledgeable about every aspect of the installation process and continually updated me every step of the way.This pandemic caused a national shortage of HVAC equipment, and Jonathan Duncklee was always so gracious in keeping me informed of the estimated delivery/installation date for this project.This company has my ultimate respect and I STRONGLY recommend them to anyone!

I was so happy with the installers and the Install went really well. They’ve really got some great people on your team!

Thank you Jonathan Duncklee for all your help and expertise. I am very happy with my four Mitsubishi wall units and to say, “Goodbye”, to those ugly window AC units for good. I am looking forward to having the heat function, too, as my kitchen in this 1850 house was always chilly. Your installation staff, Jim and Walter, were very nice and neat as a pin.

Jonathan,The install went really well. Jim and Walter did a beautiful job not to mention great guys to interface with, very professional. We enjoyed our first evening of A/C this summer and are very thankful for that. We appreciate your work pulling the job together and the effort it took to obtain the equipment. We are looking forward to learning, experimenting with and enjoying the system.Regards,Scot and Yolanda Bowes

I was very impressed by the service technicians’ attention to detail to ensure that the installation worked properly and was aesthetically pleasing. My wife and I are extremely happy with the workmanship and A/C unit. We highly recommend Duncklee to all of our friends and family.

Duncklee installed a sophisticated heating/AC system that enabled us to override an outdated and inefficient system that existed in a house we bought. Jonathan Duncklee was accessible and answered our questions in a way that made the installation and workings understandable to lay people. I would recommend Duncklee and would use them again.

We have a Mitsubishi split system and after issues with the original installing company I gave up and called Duncklee. It turns out the other company is not Mitsubishi diamond certified. Duncklee is and after their work I can see the difference.They responded quickly to emails to get a rough idea of the system before they made the on site visit. The technician was on time and quickly discovered the problem, the compressor lines were leaking. He came to show me, I have no idea how the other company missed it. He put some coolant back in as a temporary fix and had to come back for a full afternoon a week later.After he fixed the leak he flushed the system to get any water out. He then inspected the rest of the system. He fixed the large unit after some disassembly and now it works great. It's been 2 weeks, no sign of anything leaking and everything is working like new.

Our business recently had Duncklee furnish and install a Mitsubishi Mini-Split System with heat pump and air conditioning. Jonathan was very knowledgeable and patient with all of our many questions. The installation was seamless and the installers were respectful of working in our office during office hours. Could not have asked for a better experience and would highly recommend Duncklee to anyone looking to upgrade or replace their system.Anita Mather - Capalbo Mather Dougherty Accounting Services

Duncklee installed Mitsubishi 6 mini-splits in my house this month. It was a large and complicated job. The men who did the work were terrific. They always arrived on time, were respectful, worked hard all day and were a pleasure to have around. It was hot as hell when they were doing the work. They wore masks and maintained distance from my family members at all times. Best of all they did a great job and in the midst of a terrible heat wave and a pandemic we are cool and happy.
15:22 21 Jul 20
Clean, efficient, friendly, and professional! Thank you for a job well done!
15:20 16 Jul 20
The Duncklee serviceman who installed our new central AC system was friendly and incredibly knowledgeable. We were extremely impressed with the Duncklee service.
21:13 14 Jul 20
Replaced our window air conditioning units with ductless system. These are great! Pricing was extremely competitive. Installation was smooth and professional. Before leaving, installers cleaned up and spent time to make sure we understood fully how to use. Units are quiet and temperature is more consistent than our window units were. Highly recommend the ductless heat & air conditioning units and strongly recommend Duncklee Cooling & Heating to install them.
16:35 13 Jul 20
Working with Duncklee was a great experience and I refer this company to my relatives and friends .The employees from the owner to the service technician were great and could ask for more, thanks Jonathan.
18:51 02 Jul 20
My husband and I just had ductless AC installed in our house. We are very happy with the work that Dunklee did. Jason and Noah took the time to explain everything to us as they installed the units. They worked hard and even cleaned up after themselves. We highly recommend Dunklee.
19:15 01 Jul 20
Jonathan was wonderful to work with. I had 2 mini split units installed and they are working just as they were recommended. The installers were professional and did a great job with no mess left behind. Just in time for the heat wave. Thank you

We had 2 new indoor ductless units & an outdoor condenser installed. The installers, Jim & Walter, were friendly and professional. Installation took 2 days and they cleaned up each day. Jim described the operation of the remotes in simple terms and was patient with our learning curve. Later, Jon answered my questions on how to properly operate the units. Again, we appreciate him being patient with us. Excellent experience. Highly recommend!

Duncklee Heating and Cooling recently installed central air conditioning in my home. From the owner Jon Duncklee and his office staff to his installation team (Jason, Noah and Malcolm), all were very knowledgeable in the installation and operation of the system. They all took the time to answer any questions I had and they made sure I was satisfied with the answers. I was really amazed how the installation team was able to get all of that duct work into my attics. Job well done!!
15:23 01 Jun 20
We started using Duncklee a couple of years ago for the ongoing maintenance of our air conditioners (we have two units). They were recommended by our former AC contractor who got out of the residential business.When our AC was not working last week, I called on Wednesday and was pleasantly surprised that Duncklee had availability on Friday.With COVID-19, I was a bit apprehensive because we haven't had anyone in the house but us since February. There was no need. The technician showed up on time wearing a mask; I offered gloves (to protect him).He quickly found the problem of a worn-out part in the compressor and replaced it. I felt the cost was very reasonable.We are grateful because my husband works out in the heat and humidity and he appreciates coming home to a comfortable environment. I highly recommend Duncklee.

Professional, courteous, detailed ant thorough workman. Would use them again without hesitation.

The guys at Dunklee Cooling & Heating are knowledgeable, professional and always do a quality job. I worked alongside them before I opened my own shop and continue to work on projects with them today.

Outstanding!! Personalized service from the President to the on-site technicians. Showed up on-time everyday, provided the perfect amount of communication with customer, and asked questions appropriately to ensure customer satisfaction. Work was performed with a high degree of professionalism. Quality of work exceeded expectations and technicians left the work site cleaner than when they started. All personnel demonstrated a high level of knowledge in regards to installation, operation, and preventative maintenance for the units. Not to mention how accommodating they were during these challenging times...Look no further for your HVAC needs!!

I had Duncklee install a Mitsubishi mini split a/c and heating system at my house in Stonington Borough. The owner, Jonathan Duncklee, was great to work with. Very punctual and professional in manner and very knowledgeable of his products and what would be best for our situation.His crew was likewise very professional and they installed the system in a short time and were meticulous about their work and clean up.No problems whatsoever and the system is working perfectly .I cannot recommend this company more highly.
19:25 15 Apr 20
I should start by saying that there are not enough stars for me to adequately praise Duncklee's!We began using them 12-15 years ago when they first replaced our gas furnace and hot water heater with an on-demand tankless Navien heating system. Now we can take as long of a hot shower as we want!The founder of their company, Les Duncklee was a classmate at Stonington High School with my late wife, and from the beginning, everything was exceptional in terms of explaining, install, friendliness, and performance.Then we decided to have three Mitsubishi wall A/C & Heating units installed in three rooms, running out to a single outdoor fan unit. Same experience of excellence, price, service, and especially beautiful work installing and hiding the pipes going outside to the fan. Very professional install.Since then we have had regular Mitsubishi & Navien maintenance, and a required replacement of the Navien box that failed under warranty, again with prompt, friendly, professional, and expert service EVERY SINGLE TIME.It is a real tribute to Les when I have seen how Jonathan has taken over and grown the company. Also it is a valid measure of a well run company that they have had a high rate of retention of office/service/install staff. Year after year, the same familiar names come to service or fix something that was wrong. Most companies are not able to hang onto their skilled employees like this, so I wanted to bring up this important point.I give my highest possible recommendation with no reservations about using Duncklee's for your needs. 10 Stars!!The final touch to show how they go above and beyond is that Jonathan sent me flowers when he learned that my wife had passed away. What company does that? I was stunned, and so very appreciative at their genuine caring for their customers.Thank you Duncklees--and that goes to each and every employee there.Sincerely,Charles ParrotNew London, CT

Duncklee Cooling & Heating was great to work with for my conversion to a natural gas furnace. Everyone I interacted with was kind and professional. I highly recommend.
14:03 09 Mar 20
Jon and his team did an amazing job updating our HVAC system to the 21st century. We got bids from several companies, and Duncklee was very competitive from a pricing standpoint, and delivered excellent quality and service. Thank you!
15:41 06 Mar 20
Wonderful experience with the new Navien boiler install at my home in Mystic..... John made the entire decision process seamless and with no stress... he and his folks (Jason and Noah) were fabulous to work with respect to the installation and post-installation. Wish more businesses were still run like this...total customer focus and an old fashioned trusting build of a long term service relationship.. thanks, John... next step is to get the A/C units installed.. yeah!!!

Excellent company. Jonathon Dunklee is charming and a true blue businessman. He genuinely cares about his clients and his town. His father would be proud. As for the job, the installation team was great. It was a cold week but they were troopers. Good people. A job well done. No need to shop around. This is a great team. Shop local! 🙂

17:46 19 Feb 20
have used Dunklee Cooling and Heating on a new construction of a commercial building - The installation was flawless and the communication on the job was priceless. Hugh mistake was not using this company on a residential construction I also did - got it cheaper, but no value !!! Would recommend Duncklee's for any job when you want value. On time every day with no excuses. Great team that actually cares
12:54 14 Feb 20
Excellent company to work with, very informative and knowledgeable about there products and services. Duncklee installed an outdoor unit and 3 indoor Mitsubishi heating and cooling units at my house in a timely and professional manner. Neat and clean installation, very pleased with the finished product.
18:55 10 Feb 20
Very professional. I called and had some questions, they came out to my site and walked me through the entire process. The Mitsubishi Ductless units are the best things since sliced bread. I highly recommend using Dunklee Heating and Cooling.

We are restoring a 1796 old house. We were looking for the alternate heating and cooling system addition to the existing hydronic radiators. We were thinking of not having traditional central air system because of the ducts could take up too much space. We were exploring the ideas had ductless system. We had several vendors come to give us advices and proposals. Johnathan from Duncklee stood out as professional and very patient listening to our concerns. He asked to our emails even though he was vacationing in Caribbean Island. We eventually hired him since their price is reasonable, not the lowest or the highest bid that we received.We are glad we did. Their technicians are polite and did quality works. They just spent a week here installing (2) outdoor units and (5) indoor units. Jim was nice and very professional. He spent two hours just to go hours to walk through the spaces to make sure we were fine with the location of the indoor units so that they could be easily connected to the outdoor units and most importantly less visible in the interior space. He was also very meticulous about the level and center of the indoor units. When they left, the jobsite was spotless and everything looks great!! While they were here, we also hired their services for the existing radiators and they also trouble shot the issue of existing boiler.We highly recommend Duncklee. You won't disappointed!!

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.
20:46 20 Dec 19
Well manured and did their job well

We recently contracted Duncklee to install a 42k btu Mitsubishi 5 zone ductless system with hyper-heat and Kumo cloud. After operating and living with the new system for several weeks, we are beyond happy with it. I was concerned about possible dead spots throughout the house, but there's just a warm blanket of heat wherever you go now. The units are whisper quiet and incredibly efficient. You won't even notice they're on.Paige walked us through the project from start to finish. The installers Walter and Jim were total professionals. They even finished ahead of schedule, which is unheard of these days. If you're going to install a system like this, you need real pros installing and servicing it. I highly recommend Duncklee Cooling and Heating.

I knew my 1843 Victorian would pose challenges for the installation of the Mitsubishi split heating and cooling system. But from the beginning to end, it went smoothly, and I could not be happier!Jonathan Duncklee explained the process, designed the placement of units, and gave me a quote for the work. I have 8 indoor wall units and 2 outdoor units.He was available throughout the project to answer any questions, and his techs who did the installation were professional, knowledgeable, and cleaned up each day.The final bill was the same as the initial quote. No surprises.Jonathan was a wealth of information and made great suggestions.I was able to add Wi-Fi thermostats which can be adjusted from my smart phone and give an alert if the temp drops. I no longer have to worry about frozen pipes when I’m away. Also, the Mitsubishi system is a back up if the furnace goes out.They also installed pumps and ducting on my dehumidifiers, so I no longer have to physically empty them.At Jonathan’s suggestion and guidance, I had video doorbells installed. They give a layer of security and convenience I didn’t know existed.Oh, he told me about a Wi-Fi water leak/freeze sensor for the basement which I purchased and set up. Really could’ve used that a six months ago when the hot water tank leaked all over the basement.I’m grateful I chose a local company that really goes above and beyond for their customers.

I love working with Jon. His company always puts the customer first and does a quality installation.

Our house has had the pleasure of work doneby Duncklee employees for many years.Every Spring they've come to get us readyfor the heat of Summer.NOW we have a Misubishi 'device' taking care of bothchill and sweat. Also lowered electric bills. Hooray!Year 2002's Storm Sandy wiped out our central AC service,and it was promptly replaced. Our old half-house withits younger attachment makes for difficult installation,and this was done with skill.Thank you, Jonathan
23:58 05 Sep 19
Thanks to Paige for setting it all up and to Jim and Walter for a great installation...First thing my wife said, "It's too cold!!!"
