Gas Furnace Repair in Farmington Hills, MI 48334
“John G. is a stud! This man rolls up with just a rough idea of what we were dealing with (based on my best non-professional description) and was able to diagnose the problem with my furnace quickly AND ACCURATELY.
Beyond that he provided a level of transparency, knowledge, and clarity that left me with a level of trust I did not get from some of Harriman's competitors. I highly recommend Harriman generally, and John G. specifically.”
