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.

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.
