"Chris and his assistant did an excellent job of explaining the situation and options for repairing or replacing our hot water heater. In the end we chose to replace it and they were able to secure a new unit and install it within 3 hours. Would definitely recommend Chris and Tri-County Services and will use them again if another situation arises."

"Services were solid but prices are ridiculous with this company. It was a $20 part that took less than 30 minutes to install. They charged me $337.00. I should have researched before agreeing to the service. Way better values out there in NE Ohio."

"The job was done very well. Our lower level was a major problem and it turned out that our fuse box was in serious trouble. The team explained the problem and quickly fixed the lower level issues and fuse box. The bathroom fan needed parts in order for the installation to be completed to my satisfaction, the technician showed me exactly what to order and I have, he is coming back out to install them. We are pleased with the work, how easily it is to make an appointment and they were on time, in addition I received an email with the a photo of the technician and name therefore I knew ahead who was coming to my house."
