What Our Customers Say
"Outstanding is the best word I can use in describing JB Mechanical's design and installation of my new heating and hot water system. I have worked with industrial mechanical contractors for over 40 years... but have never come across a residential contractor that has spent more time to the attention to detail as Jeff."
Louie Boy
a year ago"Jeff at JB Mechanical was fantastic! Jeff came to my home to replace some thermostats... He was also able to run wires such that we could replace two separate thermostats for heating and cooling into one that controls both. It was a great experience and I will use him for all of my future HVAC needs. He is great! Thank you Jeff!!!"
