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 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!
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!
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.
Great tech, good communication and people skll s along good technical trouble shooting and diagnostic skills
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
The technicians that came today were professional and explained the problem clearly. We are looking forward to implementing the new system.
Fantastic service, very friendly, prompt.. overall they're just fantastic! Highly recommend!
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 .
Great Job!! I was really impressed with the in-depth knowledge that tech had with my system. Clean and thorough!
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!
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!
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!
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.
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.
I recently had two HVAC units installed in my home by Dual Temp Home Services, and I have to say, they exceeded my expectations in every way. I’m not easily pleased, but from start to finish, their team went above and beyond. The installers were professional, efficient, and took great care to keep my house clean. They were also mindful of my pets, which I truly appreciated!
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.
Very good service. Very reasonable and explains all issue and problems well. Very thorough and caught extra stuff
This was our first experience with Dual TempPatrick serviced our Two air conditioner units, he was very thorough and explained everything that he was doing took lots of pictures to share the condition of our units with us. We will definitely be using Dual Temp for other services
Absolutely incredible experience. First HVAC company to ask me if my airflow is comfortable. They did a thorough review and adjusted the dampers to provide better air flow and comfort. They did a really nice job installing a new humidifier for me. And also they installed a Reme Halo Air Purification in my home. They were professional and clean. Highly recommend.
