Great service and installation




Review of Wilcox Energy

A beautiful installation with a new pipe to the tank. The pipe that was replaced was crimped which resulted in reduced gas flow to the cooktop.

Review of Wilcox Energy

They show up on time or earlier ready to work. They explained the process and asked if we had any questions. Their work was neat and they cleaned up after them. So friendly and worked great together. Our dog fell in love with them and they were so nice to the dog. I do not have enough good things to say about the whole crew.

Prior to the crew coming out I received excellent service of what I needed as well as options. Day of service the team came on time. They introduced themselves and explained what they were going to do. Answered any questions I had during the installation as well as after. Tested the unit and explained how it works. Everyone was professional and Mike did a wonderful job.
