Our many decades-old AC/central heating unit broke down. Not only did the Duncklee team replace everything at a great price, they also went above and beyond to help our child with allergies. Both the built-in humidifier and the heavy duty allergen filter have been extremely helpful in keeping our son healthy.

Duncklee was amazing to work with. From the first quote when Paige came out to look at the house and the set up we wanted all the way through to Oscar getting everything installed with absolutely no disruption to our day to day, and it only took a couple of days. Absolutely easy from start to finish, and amazing education on options and available local and federal rebates for our area that made the cost comparison between having the experts doing it and DIY a no-brainer to go with Duncklee. Highly recommend.

One A/C zone failed, midsummer, ahead of visit in 2 weeks from 8 relatives. Duncklee got a repair person to us in 2 days, only to find that the unit needed to be replaced. Technician measured spaces, found only limited options, and it looked like no time for a replacement.As longtime customers of Duncklee (split system in prior home - very pleased), even we were surprised by how well this is being handled. Needed replacement was ordered ahead of my signing contract, paying deposit, and was expedited in order to get the equipment in time, rescuing us from having four little kids and their parents exposed to extremely hot summer weather/humidity.The project was completed in two days and went perfectly. (They anticipated this, so started four days before our family's arrival). An earlier technician, TC, had speced well, helping the company find a system that fit into a very tight space. The installation team, headed by Justin, was remarkably respectful of our home and two resident cats who sought to be "helpful", but weren't. They checked to make sure everything worked and was clean before leaving, even adding that if anything does go awry, don't hesitate to call. Whole team was pleasant as well.Thanks to Duncklee for a great experience and in time for a comfortable visit from our family.

Excellent customer service! During the last heat wave, our AC would not come on.

Duncklee installed Mitsubishi heat pump minisplit system at my home. The system has worked great since it was installed 6 months ago. It'll be great to use the system to cool the house when it gets really hot this week. No more window airconditioners to lug around and install - my back is very happy for that!Installers did a nice job and were very curteous, attentive & respectful.Lastly, Duncklee's price was great!Highly recommended.

His crew quickly installed the units in two days. Oscar and Fernando were very professional, courteous, timely and knew what they needed to do.

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.
Response from the owner: Hi Bill, Thanks for purchasing your new Thermopride oil hot air furnace from us and your 5 star review. Having no heat isn't fun and I was glad we were able to get your new comfort system installed quickly in your Ledyard CT home

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.
Response from the owner: Thanks Kevin for your 5 star review. The Mitsubishi mini split ductless heat pump system will provide you with year round comfort and significant savings over your electric baseboard heating. Enjoy the comfort this winter and the cooling feature this summer! It was a pleasure working with you and thank you for doing business with us.

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!
Response from the owner: H Jeffrey, Thanks for your compliments ! Delivering a 5 star experience has always been our goal. Enjoy your Mitsubishi ductless mini split heat pumps/cooling system year round for amazing comfort and savings in your Ledyard CT home.

Response from the owner: Hi Jakub, thank you for your review! The Mariner Restaurant in downtown Mystic CT can't operate in the middle of a hot and humid summer right before the Mystic Outdoor Art Festival weekend with the air conditioning down! We made your business a priority to keep you operating and replaced your old system with a Bryant/Carrier heating & air conditioning system.
