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
Terrific experience. Thank you!! Knowledgeable. Not pushy at all. Friendly. Immediately got down to work. Punctual arrival. Professional service.
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!
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.
Joe from Dual Temp was very knowledgable, asked clarifying questions to understand what we want and what we need to get us the best benefit and pricing proposals. Very Satisfied!
Patrick did a nice job, very thorough, explained everything, streamlined a few items, pleasant and efficient.
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 .
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.
Outstanding service and top notch customer service. Patrick came over was super friendly and very professional. He explained all my issues and options to get my home running safely again. I will definitely call again to schedule a full upgrade. Thanks to Patrick and this company I now know how I was blind to the dangerous furnaces I been running in my home. Thanks for coming right away when all the other companies only gave excuses and appointments for a future day.
Great Job!! I was really impressed with the in-depth knowledge that tech had with my system. Clean and thorough!
Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
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.
Great pricing and quick response time with work finished early. The crew was courteous, communicative, and extremely helpful. It was a pleasure doing business with Dual Temp. 5 ⭐️
we were on vacation when our air conditioner went on the fritz with only our dog sitter at our house. We called Dual Temp and they got a guy out there the next morning to work on it. The technicians name was Patrick, who is definitely accredited, his profession, very professional and friendly, got our system up and running in no time answered all our questions Any potential problems that we have that need to be addressed. What a great experience. These guys put us at ease and took care of our problems so it didn’t affect our vacation. Thank you, Dual Temp and Joe
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!
Wow, what a great experience! I had Dual Temp install a Tankless Hot Water Heater in my home. The entire experience and crew was tip top from 1st inquiry call to final install. Dual Temp was professional, experienced, respectful of my home and they worked really hard to make everything PERFECT.. They did such a great job, now i even gained closet space where the old hot water heater was!!! Thank you Dual Temp, I look forward to recommending you to my friends and family. Thanks again!!
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!
