Great people and a pleasure to work with. I had my AC system installed by Duncklee years ago and now they keep it running perfectly. Will never go anywhere else.

Installation of HVAC system was done fast and efficiently. Crew was informative, friendly and professional. Highly recommended.

I had booked a maintenance appointment through Home Depot where I assumed my Mitsubishi unit was purchased. They canceled last minute and were very rude. I then called Duncklee and they were very friendly, much quicker to get me an appointment, and I love that they are a local business. Today Andy came to my house and was lovely. He was great to chat with, thorough in his work, kind to my dog, and also educated me on my AC system. They were more expensive, but worth it. I highly recommend and will definitely be calling them from now on.

We had an outstanding experience working with Jonathan and the Duncklee team. Their installation of our AC units was incredibly smooth and professional from start to finish. Jonathan was responsive, knowledgeable, and made the entire process seamless.

As a nonprofit arts organization, we deeply appreciate working with businesses that show integrity and a true commitment to the community. Duncklee exemplifies that. Their support means a great deal to us, and we’re grateful for the partnership.

Highly recommended!

Very dependable company, stands behind their work

Glen, Dan, Jonathan, & the Duncklee crew altogether were great! Made a service call and they were able to come out next day. Part was needed, they immediately gave me a quote and ordered. Glen was our tech and he made sure we had heat for the start of the weekend! Appreciate all your hard work. Great company and highly recommend!

I had an excellent experience working with Duncklee. They recently installed a new high efficiency boiler to replace my aging one. Jonathan was quick to answer any questions, the front office staff was kind and helpful, and the install team was friendly and efficient. I’d highly recommend them to anyone.

We've used Duncklee 3 times for major work (HVAC, water, heating). First time we found them professional, tidy, quick, and 30% cheaper than other bids. The next two times we didn't shop around! Highly recommended.

Absolutely impressed with the service! The AC unit installed works perfectly and is of great quality. The owner is very friendly and provided detailed and helpful advice. Thank you for the excellent service. Highly recommend!

I cannot recommend Duncklee Cooling and Heating enough! From start to finish, my experience with this company was absolutely top-notch. Jonathan, in particular, deserves special recognition for his incredible attention to detail and outstanding customer service.

My furnace died unexpectedly while I was away on business, and the situation could have been a nightmare. But knowing Jonathan and the team at Duncklee were handling it gave me complete peace of mind. I wouldn’t have trusted anyone else to replace my furnace while I was out of town. Jonathan took care of everything with such professionalism and care that I felt like I was there overseeing the work myself.

He took the time to thoroughly assess the situation, kept me informed every step of the way, and made sure everything was done to the highest standard. His meticulous attention to detail and commitment to quality were evident throughout the entire process. What truly sets Jonathan apart, though, is his genuine care for his customers. He not only solved the problem but went above and beyond to ensure everything was perfect when I returned home.

Thanks to Jonathan and the team at Duncklee Cooling and Heating, my home is now more comfortable than ever, and I have complete confidence in the quality of their work. If you’re looking for a company that combines expertise, precision, and exceptional service, look no further. They’ve earned a customer for life!

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.

Duncklee installed a new York a/c unit at our home . Did great job . Very well run professional company. Their technicians that service our home are all experienced and do great job .

Highly recommend!! 10/10!!
The team is extremely kind, helpful and professional. They were able to fix our A/C unit fast and efficiently. I definitely plan to use them again with any more heating or cooling issues I have in the future.

Great customer service ! Excellent communication by their team! Fixed our AC splits! Highly recommended to anyone with cooling Or heating issues!! 10/10!!

Excellent customer service! During the last heat wave, our AC would not come on. Barb immediately made calls to customers that did not have such a dire need for service in order to get us an earlier appointment than the maintenance call we originally had scheduled. We are up and running and very grateful to Jonathan and team!

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.

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!

Excellent sales and install staff! Very professional, flexible, thorough and great with pricing and customizing!

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.

Guys were very nice and professional and our service was prompt for our replacement unit. We have used Duncklee for our heating and air for 14 years and they are always great.

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.

Congratulations on 50 years in business.

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.

We have been with this company for 5 years and they have been super in responding to our calls and needs. Can't say enogh good things. I would hesitate to buy this excellent product and know the servicing will be followed through if need be.

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.

If you ever need A/C or heat in your house.... call Duncklee.... Very profressional, arrive on time, never leave a mess in your house. Highly recomened!!

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.

Extremely helpful, honest and great support. System has been working great for years.

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!

Very fast, professional and reliable, Jonathan Duncklee saved my business! He was able to get new commercial HVAC unit and have it installed in less than 2 weeks when other companies quoted me months. Definitely highly recommended!

Pro crew, excellent work

Through, courteous, attention to customer's property.

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.
