I’m turning an out-building into my dream shop, and Dunklee helped with the heating and cooling. They guided me through the process of choosing the right unit, and the installation by Jim & Oscar was done efficiently and quickly.It was a great pleasure to do business with them and I will definitely call them again for any future H/V/AC projects!Highly recommended.

I'm sure this is nothing new to you, but I would like to share how I am/was so very impressed by the professionalism of all your staff. I have not witnessed such dedication, respect and talent in tradesmen in a very long time.I am most at ease that my new boiler will provide unconditional warmth! I highly recommend services rendered by Duncklee Cooling & Heating Inc.

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!

During a brutal heat wave, my A/C stopped working. Called Duncklee and they had a tech out within hours......during a very busy time, for sure! Issue wasn't that easy to find, but the tech realized that the electrical control board was not working. He got on the phone, got the part ordered from the factory, expedited the shipping, and two days later, came out to install the new board. He also did the PM check I'd had scheduled for next month, which saved me another visit. Very pleased with the response and the communication from all the Duncklee staff. It's why I've been a customer for over 10 years!

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.

I purchased a peplacement heat pump and air handler from Duncklee. The instalation was very professional and completed in one day. Although the unit was delayed due to supply issues, they kept me informed about the procurement difficulties they were facing. All in all a very positive experience.

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!

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.

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.

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.

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!!

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.

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.

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

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!!

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.

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

We want to express our utmost satisfaction with the service call this morning from Duncklee Inc. for our Mitsubishi AC system.Glen, the Duncklee technician, performed a thorough assessment of the issue, and with equal thoroughness and expertise, resolved the issue. Glen’s attention to the smallest detail and his professionalism provided us peace mind that our system could resume operation at full capacity. He also offered very helpful insights to our air conditioning system regarding regular care that will help the system to run efficiently going forward. Glen was also very good humored about navigating the measures taken to protect the wood floors in the apartment. : )Our hearty thanks to Glen and the service department at Duncklee, Inc.!Sincerely,Bill Hossack & Elisa Giommi

Duncklee is a great company. Their communication is better than anyone else I've ever dealt with in the contractor field. Their work was done in a great way. Very professional and courteous. Even when their company had someone get not be able to work for a while they were able to fill in and get the job done without any delay. If we ever needed to do air conditioning again we would use Duncklee.

We had a 5 unit Mitsubishi ductless heating & cooling system installed last week by Duncklee Cooling & Heating Inc. The installation went off without a hitch. Jim, the installer, told us the project would take 5 days and it took exactly 5 days. Jim was extremely punctual, very neat, explained everything he was going to do and why it had to be done that way. When everything was installed, Jim went out of his way to clearly answer my many questions about the units. I highly recommend Duncklee for your heating & cooling needs.

Duncklee Cooling & Heating did a great job installing our Mitsubishi ductless cooling system. The work was completed in a timely manner and Jim and crew cleaned everything up each day. When the installation was complete Jim gave us a thorough training on how the units work and made sure we were registered for the warrantee coverage. We are very happy with our new system - it is very quiet and we are enjoying using the heating function on these cool fall mornings.

Jim and Noah could not have been better! I was home for most of the install, and they were both amazing, professional and went through everything thoroughly, answering all my questions! We will absolutely use Duncklee again and recommend them to others.

I've known Jonathan for more than 20 years. He and his company have had the highest level of customer service reviews for as long as I have known him. Prior to the concept of online reviews, Duncklee had a wall of customer postcards glowing about the service he and his company provided. Jonathan, as his father before him, has been a pillar of our community. If you have the need for HVAC installation, replacement, or service, call Duncklee and experience customer service as it should be.

Everything went well today. Much better than I expected. I was very impressed with the service provided by Jason and Kyle the installers from Duncklee.. The install was completed today around 2:30 and they tested the system to make sure it was wired correctly. They did a great job of answering my questions, and did an excellent job of cleaning up. I will definitely refer Duncklee to my neighbors and friends for their heating and cooling systems needs.

It is rare to find a company that actually values its clients in this day and age, and the customer service I received from Duncklee Cooling and Heating was absolutely superb. As a new homeowner looking to install a central air system, I was completely lost and had dozens of questions, and Jonathan was patient and answered every single one! He took the time to explain the different options to me, and followed up several times to make sure I fully understood the system that we decided on and to give me a chance to ask more questions. Thanks to Duncklee Cooling and Heating I have complete peace of mind and a comfortable home!!
