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!

Peter L.

Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff

Kathy D.

Our furnace decided to give us a problem and stop working on one of the coldest days of the year!!! I frantically called/left messages with numerous HVAC companies who either couldn’t help us because we weren’t regular customers or couldn’t get to us for at least two days! Our technician David returned my call, got info he needed to see if he could help and got back to me immediately to say he had the part and could be here in 30 minutes. He was extremely knowledgeable, professional and polite. Our furnace was repaired quickly and kicking out heat again. Price was also much lower than others for emergency call. We are very pleased and highly recommend.

We have only been working with Dual Temp for approximately two months, but we cannot say enough good things about them. Our commercial building has a unique HVAC system, to say the least, and we have already had several occasions on which we have had to make service requests. Dual Temp responds to calls and emails quickly and keeps the customer updated of progress. Nate and his great team of techs—specifically, Noah, Jeff, Bill and the other Noah—are all knowledgeable and very relatable when sharing information and options. It was a very lucky day for us when we connected with Bob, our Dual Tech salesperson, who is diligent about keeping in touch to ensure our needs are being met. Dual Temp now has our finicky HVAC equipment up and running, and we are most appreciative!

Peggy P.

Sandra M.

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!

Chelsea W.

Joe was prompt, professional & helpful! His communication skills are excellent & I appreciate the organization of his work flow. Very glad we were referred to him!

Vicky D.

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 .

Todd P.

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.

Asher S.

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.

S B.

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!

Chris O.

Dual Temp Home Services delivered a great customer experience - easy scheduling, proactive communications, and reasonable pricing. Our technician Patrick Boyle was awesome - arrived on time, friendly, knowledgeable, helpful, and courteous! A true professional! Definitely recommend having Dual Temp and Patrick support your HVAC needs!

Excellent company for a commercial property

Bill W.

Terrific experience. Thank you!! Knowledgeable. Not pushy at all. Friendly. Immediately got down to work. Punctual arrival. Professional service.

Kathryn R.

Patrick is polite and very informed. He shows concern and makes recommendations to address anything that could be problematic or preventative for future issues with our furnace.

Daniella A.

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!

Terry N.

I recently called Dual Temp to fix a broken hose faucet outside my house. I couldn't be happier with the service! Patrick arrived promptly, fixed the issue in no time, and was incredibly polite. He made sure the work was done neatly and left everything spotless. I again have water outside my house! A great experience! I'll definitely use them again!

john J.

Theodore K.

Patrick is extremely knowledgeable and did an excellent job servicing my heating system. I would highly recommend him to anyone!
