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!
Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.
We have been using Dual Temp for several years now and we are very satisfied with the service. Reactionary maintenance and/or emergency items are hard to manage from a remote site. Dual Temp does a GREAT JOB of taking care of our maintenance needs and they react in a timely manner.
We will definitely use Dual Temp again. From Joe doing the estimate to Patrick installing new baseboard heat registers they were friendly, professional and we were very happy with the price. Patrick did a great job, so happy we chose them!
Just wanted to give a special thanks to Patrick Boyle of Dual Temp for coming out today and fixing my gas furnace in a speedy and efficient manner, from diagnoses to fixing the issue went very well , he knows what hes doing !
Dual Temp is a dependable and customer focused organization. They quickly respond and the scheduling process is user friendly. Patrick has been to our home on multiple occasions and is thorough, explaining the work he’s doing, what he finds, and recommendations for repairs and/or upgrades.

Patrick Boyle, my Technician, went above and beyond to complete my furnace tuneup to my Total Satisfaction. From the text to inform me that he was on his way, to a follow-up phone call to explain what work was preformed. This was my first time using Dual Temp, And they are now the ONLY HVAC company that I will ever use! Thanks Patrick…. And Dual Temp.
Service was excellent. The technician Patrick Boyle showed up on time, check over other contractors work to make sure it was right, install the new part continued to make sure everything was correct before adding the refrigerant. He also explained everything that he was doing to me and answer all my question in detail, and I had a lot of questions. Would recommend to anybody needing HVAC work.
Although we weren’t able to solve the problem during his visit, Patrick was very helpful in explaining the issue and course of action needed.

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.
I can’t say enough good things about our experience with Dual Temp. After several issues with our AC over the last several months it was determined that it was time to start looking for a new system. I called on a Friday morning to request a quote. They were able to have someone come out the same day. Joe was great. He was very nice and answered my husband’s questions as well as address a concern we had with air flow to our bedroom due to a smashed piece of ductwork that’s been that way apparently since the house was built. I had an estimate in my email around 5 PM that same evening. We were provided with 3 options in the quote. Sort of a good, better, best option. We had a few additional questions which I emailed Joe about and he was very quick and responsive to my questions. After getting one other quote from another company we decided to go with Dual Temp. After only 2 weeks from the initial quote our new system was installed this week. Patrick and David were the technicians that came to install and they were just as amazing to work with. They were polite, knowledgeable and explained the system and new thermostat very well. I am not one to typically write reviews but I do read them while doing my research. I can only suggest that you give them a chance at addressing your needs. Thanks again for the great service. I look forward to the same great service in the future for routine maintenance as needed.
Patrick was very helpful. He told us exactly was he was doing and what was going on with our system. I would recommend Dual Temp for your home services needs.
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!
I have the joy of working with the Dual Temp home services team on a regular basis. From Patrick in service, to David and Shawn in install, to Joe and Kim in the office, I can tell you these guys are truly top notch in their trade and even better human beings. They genuinely care for their customers and demonstrate it every day.
Patrick did a nice job, very thorough, explained everything, streamlined a few items, pleasant and efficient.
