Patrick was able to fix our furnace issue, including locating the spare parts at an acceptable price level. I appreciate the professionalism and quality of service. Thank you

Antonio P.

Patrick was very professional in his time at my house. Went over my system to troubleshoot the issues I was having with my ac unit. Gave me a great description of what happened and options to repair. He also found an issue with my propane water heater that was a potential safety concern and I was able to get that resolved. It was still under warranty from our plumber so with Patrick find he was able to solve the issue. It was lucky I made the call to Dual Temp for Service.

Penny 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

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!

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.

Stephanie R.

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 quick professional and very knowledgeable and efficient

Peter L.

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

Monica H.

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!

Mike K.

Very pleasant atmosphere. Customer friendly. Has always been a pleasure dealing with any person there, from technicians all the way to the owner himself.

Ralph C.

Patrick Boyle was awesome, straightforward and right to the point. That we didn’t follow through with the plan we knew exactly where we stood with Patrick and Dual Temp . Thank you, Ralph

Ray S.

Staff was courteous, well trained and did an excellent installation

Bill D.

Best commercial HVAC company anywhere!

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!

Bill M.

Very professional and highly qualified. Worked on my commercial freezer and fixed a long time problem no one else has. Highly recommend and thanks!!!!

Bill W.

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

Kris F.

Technician responded quickly on a holiday and we scheduled for a repair the next day. He was commutative and friendly through out the repair process as well as a problem solver when faced with a change. Pricing was more than fair!

Mike S.

HIGHLY RECOMMEND!! On time, friendly, informative, and super efficient. Extremely pleased with Patrick and the job he did servicing our boiler, tankless water htr, & mini-split systems. Great job! 👍
