Dennis Marshman was our service tech. He was very pleasant, informative and understanding. Took the time during the tank inspection to explain what happened to the tank and confirmed the replacement and date and time the replacement would occur. He also installed our tank the next day. Continued with being very informative, polite, helpful and very professional. Took the time to explain other services available from Reliance as well as the protection plans available.

We had an issue with our furnace, in a panic we called Keenan heating. The on-call service was quick and brief, within 5 minutes I had a reply phone call and a technician was en route. He was friendly, honest and described in full detail on what was happening with our furnace. After he left, I felt well educated and confident on the repair job done. I would recommend Keenan to anyone who's having a difficult time with their furnace.

Alex and his crew came in to replace my Furnace and Hot Water Tank, as well as install an Air Conditioner. They were extremely professional and explained what they were doing and why they went on to explain the units thoroughly. I was very satisfied with all the work done.
