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!
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.
Just wanted to give a special thanks to Patrick Boyle of Dual Temp for coming out today and fixing my gas furnace in a speedy and efficient manner, from diagnoses to fixing the issue went very well , he knows what hes doing !
Service was excellent. The technician Patrick Boyle showed up on time, check over other contractors work to make sure it was right, install the new part continued to make sure everything was correct before adding the refrigerant. He also explained everything that he was doing to me and answer all my question in detail, and I had a lot of questions. Would recommend to anybody needing HVAC work.
Hi ,we Hired Dual Temp to install a new gas furnace and new water Heater, They did an excellent job! They are very professional and the price was very reasonable. I would definitely hire them again in the future.Thank you !! Sincerely Harry R.
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.
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.
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
Patrick was considerate and professional in installing our new hot water heater. It was a pleasure dealing with Patrick and everyone at Dual Temp.
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!
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!
