"Michael offered great advice on where to place our new tankless heater and his team did a great job executing. There were a few hiccups that came with replacing the old tank heater and working with the old plumbing of the home, but Jax Mechanical were able to solve any problems that popped up. Michael was also proactive in the initial discussion and found that our PRV needed replacing which was something we were glad he found before it led to any long term issues."

"Do NOT Work With ServiceChampion Unprofessional, Unreliable, Unresponsive I deeply regret choosing ServiceChampion for my HVAC installation. It has been a nightmare from start to finish. They installed a malfunctioning AC unit in October, and despite MONTHS of trying to resolve the issue, it still doesnt work. Heres a breakdown of their failures: Incompetent Installation: The system has been plagued with problems since day one thermostat malfunctions, the heat pump failing, and constant disconnections. Poor Communication: Ive made countless phone calls and emails, often receiving empty responses or no reply at all. The communication has been fragmented and disorganized. Unclear Solutions: Even when they identify a potential issue, they take forever to provide a solution. Technicians seem unsure, and Ive been given conflicting information. Lack of Accountability: Despite promises of a 100% satisfaction guarantee, theyve wasted my time, money, and caused immense stress especially with a new baby in the house. ServiceChampions negligence and lack of professionalism are appalling. They do not value their customers or stand behind their work. If you need reliable HVAC services, look elsewhere. I urge you to avoid ServiceChampion at all costs."

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."
