Very responsive and thorough which is hard to find these days. The service was definitely worth the value.
After using another company to try to figure out an issue with our mini splits over the course of several visits, we called Dual Temp - they sent 2 people out the same morning who identified the issue within an hour, explained how the whole system worked, and explained the needed repairs. We’re very happy to move forward with Dual Temp and appreciate the professionalism and expertise!

This was our first experience with Dual TempPatrick serviced our Two air conditioner units, he was very thorough and explained everything that he was doing took lots of pictures to share the condition of our units with us. We will definitely be using Dual Temp for other services
Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
Excellent trouble shooting and great remedial proposals. Knowledgeable and efficient technician
Patrick was very knowledgeable and thorough. He did a great job servicing our heating and air conditioning units.
We moved into an old home with an old oil furnace that we knew was on its way out. Joe, David, and crew were great and replaced our old furnace with a new one. We had only one issue which was that the additional room that was added onto this house in 2010 didn’t include a way to bleed out the baseboards. They found a solution and fixed the issue. Dual temp is a great company with great people!
Hi ,we Hired Dual Temp to install a new gas furnace and new water Heater, They did an excellent job! They are very professional and the price was very reasonable. I would definitely hire them again in the future.Thank you !! Sincerely Harry R.

Great service! This company repaired my air conditioning unit this week . David is an awesome technician. He’s polite respectful and thorough. I’m incredibly happy with the companies service this week and David is a great representation of your company…. Thank you
David called to ask if he could arrive a little earlier than he was expected. He was coming to do my routine yearly service on my furnace. Once he was there he did an excellent job and I would definitely recommend Dual Temp!
Always timely, polite, professional and informative. Makes making decisions easy. Great to work with outstanding service. I can highly recommend.
The technician was very professional. I had annual service on my AC, furnace and water heater. The tech reviewed findings with me and discussed options. He gave honest feedback even when the answer was probably not worth it considering the expected life of my water heater. That showed they are a company you can trust. Not one that just looks to sell unnecessary modifications. Very pleased and will continue to use their services .
Joe was a number 10 .clearly a good guy! Very pleasant,friendly,answered my guestions and calmed me down! Das is good! Thank-you Thank-you! God wins!
David came out and did a great job and was done within an hour. didn’t try to sneak in any kind of fees or charge for extra time.
Needed a new heating/ac system installed. Received a few estimates and had a friend refer me to Dual Temp because she had a great experience. Joe came out promptly and provided us with 4 options. Very knowledgeable in helping with our unique situation. Installation was prompt and quick. The young men who came out were extremely professional and very considerate. Would highly recommend them!
Patrick is amazing. So is the entire dual temp team. They really take their customer service to the level of extraordinary. I highly recommend dual temp for any and all HVAC needs. So happy they are doing residential now. Just amazing updated June 2025
