"Hired West Mechanical to install a bathroom exhaust fan and light fixtures. Exhaust fan was left with duct disconnected and wiring exposed. Called Customer Service multiple times over 3-week period to get an estimate to reconnect the duct and address the wiring, still unresolved with open permit. UPDATE: I received a call from one of the company owners when he was made aware of the issue. He apologized for what I experienced and said it was very atypical for the company. He arranged to have an electrician complete the work the next day. The work included installation of a new duct transition that was not in the original scope, which was done at no charge. West Mechanical also sent a Supervisor the day after the work was completed to verify that the work was done to my satisfaction. Although I was unsatisfied earlier, I recognize that not every job will go as planned and I have been very impressed by how West Mechanical has responded. I would not hesitate to use them in the future."

"I am extremely pleased with my services from Tripped Electric. From working with their administrative staff (Tessa) on scheduling, to the 4 electricians who worked at my home (Jacob, Skyler, Marcus, and Justin) -- this business could not be better at what they do or more professional. I would 100% work with Tripped again for any of my electrical needs."
