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.

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!

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.

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.

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.

Our home has mini splits installed by Duncklee at a cost of over $17,000. When they all stopped working we called Duncklee to repair them. The technicians from Duncklee told us the units were all installed improperly, by Duncklee and they were unsure how they ever functioned based on the poor installation. They charged us $472 for this information and gave us a verbal quote of $1800+ to 'maybe' fix the problem, and left us with all the units still not working.

We called and emailed Duncklee, trying to get clarification on how they would remedy this situation, since their own admission states it was their poor wormanship that caused them not to work. Not only were our requests ignored but we never received any paper work or receipt for the 'work' that was done. This company is not reputable. Any company that ignores customer contact and doesn't stand behind their work/products is NOT a good company. Hopefully they will respond to the Better Business Bureau.

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.
