I have been using Mike Graham HVAC and Plumbing for 10 years now and I tell you truthfully that I have never had a problem with them. They installed my HVAC when my house was built in 2008 and performed all the maintenance on it. When I upgraded my HVAC in 2016 to zoned heating and air they installed that also. This company hires only the best professionals to do the work and stands behind their work 100 percent. Josh Davidson is wonderful on the HVAC side and Andrew Weed is the best plumber around. As long as they are in business is how long I will be their customer.
