Joe was professional and personable. He shared all relevant information and added much to our understanding of what was available. A really good interaction.
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.
The technician was punctual, thorough, clean, and friendly. Our home is in good hands with Dual Temp.
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! 👍
Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
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.
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!
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.
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!
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!
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!
We are pleased to post the exceptional experience we received from DUAL TEMP today. From the initial contact with Kim , who professionally and promptly dispatched a skilled tech named Patrick. Between these two 5star team players , our HVAC issue was resolved in a timely manner and at a reasonable rate. We’re definitely going to be repeat customers and highly recommend them.
Joe came over to give me an estimate on a new boiler. He was very professional and knowledgeable. He explained my options and answered all the questions that I had I feel it was a very productive meeting and I walked away feeling comfortable.
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
Patrick was considerate and professional in installing our new hot water heater. It was a pleasure dealing with Patrick and everyone at Dual Temp.
David D'Agostino was very thorough, professional and knowledgeable about my furnace and heat pump. He explained about the failed part, gave me the option to replace or wait. Great service call. I will have Dual Temp and hopefully, David, for future maintenance.
Patrick did a nice job, very thorough, explained everything, streamlined a few items, pleasant and efficient.
Response time is very good. Techs are professional and good to work with. Great at analyzing and repairs.Always glad to see DualTemp onsite making us all look good. Thanks for your Great services.
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!
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
