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 Parrot New London, CT

Excellent overall experience, highly recommended! Jonathan came out quickly to look at installing a Navien Combi Boiler and give me a quote that same day. Technicians (Jason and Kyle) were very knowledgeable, hard-working, courteous and answered all of my questions. They did good quality work, and everything works perfectly.

Duncklee claimed to be a Carrier approved repair organization. They came to my house multiple times as they said their diagnosis was that my pressure valves had to be replaced (under warranty). They replaced the valves yet the system still did not work. They refused to return to my home to continue to try and fix the problem until they received additional money from me yet they still hadn't fixed anything. Meanwhile it is the middle of November and I am W/O heat. Duncklee didn't care- they left me W/O heat for more than month. I refused to pay them for work as they hadn't fixed anything. I had already paid them over $500 and they were requiring $500 more- again- THEY FIXED NOTHING. I brought in a different HVAC Technician who had my system fixed in 20 minutes for less than $300. I'm not sure what was more amazing Duncklee's lack of professionalism or their complete and total incompetence.

Duncklee was the third company I had contacted, and the first to understand how to install a system in a house with a difficult layout. I rely on them for all my heating and cooling needs, and have never had any reason to consider another firm. They sell top-of-the-line products, their service men are professional and well-trained, and the office staff members are always helpful and responsive.

I have been using Duncklee Heating and Air for over 10 years. The most recent encounter was not up to par. I had them out on 4 occasions in a month as my furnace was not working. I paid the $400 Sunday call out fee on the first visit. I had no concern over paying this. Two weeks later, the furnace was out again. They were there on two occasions, the first time on a Thursday, the second time on the Sunday THREE DAYS later. The invoice from the Thursday stated that the problem was fixed and no other problems were noted, yet THREE DAYS later, they were out again and charged a $400 fee plus the charges for parts and labour to fix the problem I asked that the $400 call out fee be waived as the furnace had just been inspected THREE DAYS before. I paid all the bills, never asked for any of the other fees to be dropped except the second $400 call out fee. Mr Duncklee practically accused me of trying to get something for nothing, after 10 years of being a good customer. I had expected them to guarantee their work, and I am most disappointed in the response from Mr Duncklee. I would not recommend them again.

technician jay came out ran test and called manufacture of furnace and determined the wrong size intake and venting pipes were used causing condensation build up in pipes and tripping pressure switch. jay was very professional and very good at what he does. even know it was a service call , he was able to call office and stay and re install the correct venting pipes. i was very impressed with there fast and great service and would definitely recommend them again.

The company gives you a scheduled time window for the technician to arrive, unfortunately for me on the original date of service a technician called in sick so everyone was running behind. Instead of calling early in the window of arrival to inform me of this, it took me calling the company at the end of the time window to find this out. Once I called I was informed of the situation and that a technician wouldn't be able to make it to my house at all that day. I was forced to reschedule for a week later because it was the only time I had available and this time the technician showed up within the time window and fixed the problem in about 10-15 minutes. There was a part that was connected on my A/C unit that was not needed and so the technician removed it and the unit started right up.
The technician was kind enough to show me how to change the filter on the heater/blower for my system. He also took a look at some home repairs I did where I moved a vent and the cold air return and verified that everything I did would have no negative effects on my system.
The company was very upfront about the cost of the visit, where there is a trip charge plus the first hour of labor is charged no matter how long the technician is on site for. After that hour the labor is charged in fifteen minute increments and any necessary parts are in addition to the labor charges.

DO YOU BELIEVE THIS I JUST WANT EVERYONE TO KNOW WHAT KIND OF COMPANY DOES THIS. HONESTLY ....LET ME SEE NO I WILL NOT RETRACT MY REVIEW AT THIS POINT I WILL CONTACT A DIFFERENT COMPANY AND THE COMPANY WHO MADE THE HEATING AND COOLING UNIT-- GUARDIAN. THANKS ANYWAY JONATHON.....


first review
well to start they came to our condo and they installed the heating and cooling unit after that they told me that they would have to tweek the system and this unit was installed in January of this year. So here it is summer and the weather changed and has gotten warmer we called the company and they came out and found a leak with the Freon and supposedly fixed it and stated if we have any more issues to please call the unit is under warranty. Which leads me to today the temperature outside is 85 degrees and we put the air conditioner on and find that it is not working properly again so we call Duncklee and the receptionist answers and I explain what is going on that the temperature inside is 69 degrees and we want it cooler because inside it did not feel like it was 69 degrees, cooler than outside yes but not 69 degrees so the receptionist tells me to hold on and she talks to a technician who in turns says if we turn the temperature down the unit will freeze up if below 68 degrees and then the tech gets on the phone and we are telling him it does not feel like 69 in the house that something is wrong and again they tell us it will never be cooler than it is in the condo mind you I state CONDO not big house and we had the air conditioner on all day!! So they tell us if they come out and nothing is wrong they will charge us a fee for this service!! At this point I am so upset, and ask to set up a day for them to come out and they give me THREE WEEKS FROM TODAY!!!! Are you kidding me REALLY!! They are so unprofessional for a company they take your money and they don't come out and fix it under warranty!!
So I advise anyone looking to have a heating and cooling unit installed and maintained DON'T CALL THIS COMPANY YOU WILL WISH YOU DIDN'T!!!
Response from Duncklee Inc
"We worked very closely with [member name removed] when they originally purchased the system in September 2012 from us. We held the system here while they made payments, and we didn’t charge any interest charges. Also we worked closely with their friend who made the final payment so they could get their system installed sooner than later. When these two ladies called screaming at our office staff that there system was set at 68 degrees and the room was reading 69 degrees we thought they were kidding about the one degree difference, but as the conversation from these two women grew hostile, they proceed to not only scream obscenities at my staff they left vulgar voice mail messages that I saved and would be happy to share them with anyone who wants to hear the vicious, selfish and belligerent attitude of these two women. We tried to explain to them a few things to them in between their barrage of insults: 1. You have air conditioning, it works, and we have customer who have systems not working and they would need to wait for a service call. 2. That the system will only give you about a 20 degree difference from indoor to outdoor temperature and it was approaching 90 degrees outside. So if its 90 outside you should achieve 70 inside A one degree difference is not a sign the system is broken and that if we come for a service call and nothing is wrong there will be a charge for the service call. In our 40 years of business we have never had anyone call here screaming at us that there is a 1 degree difference and that we must come now! We do not service clients that are abusive and hostile. At this point we told these two women that we will no longer be serving their system. I did reach out to their friend that helped pay for their system so they could get it installed and asked if there was something emotionally wrong with them and her response was I don’t want to get involved, and that they have anger issues. Lastly, we do not respond to messages with such an aggressive and abusive attitude. So I ignored all belligerent messages they left on my voice mail system. Finally, [member name removed] did call to apologize about their irrational behavior. I returned her call only because she took ownership of the situation and then I explained to her we do not conduct business with people that behave that way. And I would appreciate that they retract the unfair negative statement from Angie’s list because we are polite and professional and do not engage in abusive and belligerent transactions"

the initial visit from technician was expensive and did not resolve any problems. I was charged for about two hours so that I could hear what I had told him was wrong with the unit! I was promised to have the unit repaired within 7-10 days. It took more than three weeks! The repair work was okay and the two installers that completed the work were polite and thorough. I just wish that the owners themselves were as responsive to customer as they were quick in charging their very high rates.
Response from Duncklee Inc
"This customer, , whose account was closed out and was in third-party collection because he never paid us for service in the past, presented a unique dilemma. Because of this situation, we required him to pay his previous balance before we could move forward ordering parts or providing additional service. Despite this situation, we informed the customer the work could be done under manufacturer’s warranty; we worked hard and researched this product’s warranty status saving him a considerable amount of money. We quoted him 7-10 business days (which translates to 14 regular calendar days) plus shipping time to receive the new coil. This is what the distributor quotes us. Once the coil arrived, we contacted the customer to schedule the installation. This is fully consistent with our company procedures. Because we have no control over availability or shipping, our policy is to wait until the part has arrived before scheduling work. We dispute the customer’s timeline of more than three weeks to order the new coil and get it installed. Our records indicate the new coil was installed 17 days from the day of diagnosis. We consider this to be exemplary service, especially when you consider the impact his delinquent payments had on the timeline."

Would NEVER recommend company. When the water heater was installed, the hot water relief valve was placed at the top of the water heater, rather than run down the side of the tank toward the floor. If the water heater blew, hot water would be spraying all over. A plumbing company corrected the problem and said Duncklee had done the work improperly. In addition, the crew left wires hanging out of the walls on the lower level -- exposed and uncapped. I had to have an electrician correct that problem. I requested Jonathan Duncklee come over and view the situation and he never came. In addition, the 3/4-inch PVC condensation line was improperly installed in the main vent stack and leaked throughout the upper level. I was informed by other HVAC technicians that the hole was made too large and the line barely inserted, resulting in the line falling out and causing water from the condensation to leak throughout, staining my newly painted ceilings. I was advised by three HVAC persons that one does NOT dump into the vent stack and the imporper installation of the drain pipe caused it to pop out. Mr. Duncklee was unresponsive to my complaints. Other service people had to be hired to correct the situation.
Response from Duncklee Inc
"We are sorry that Member chose to unnecessarily spend money for a plumber, an electrician and three HVAC technicians to perform work we would have done without charge ... If it needed to be done in the first place. If she gave us the opportunity, we at Duncklee Cooling & Heating warrantee all our work and would have been glad to come out to come to the house to explain the work performed (each system is a custom design), answer any questions and rectify any issues or potential issues. Duncklee Cooling & Heating has been servicing the Eastern Connecticut & Rhode Island area since 1973. We stand behind the products we install and our workmanship. Our goal is 100 percent customer satisfaction; all we ask is the opportunity to serve you."

Very well, after a visit when they sized the job to determine which system I would need (I had already researched this and had other people come give me estimates) we agreed on a system and I provided half of the payment (they do also offer financing). I was scheduled to have it installed within a month but they were able to get me in just 2 weeks later. The installer was very knowledgeable and very helpful. He arrived on time, cleaned up each day and let me know where he was at the end of each day. He provided excellent training on the system as well which was greatly appreciated.
