Charlie Rich was professional and courteous in all of his interactions. He listened closely to my explanation of the furnace problem symptoms. He thoroughly checked out both the furnace and AC unit. After completing diagnostics on the furnace and problem solving, he isolated the problem to the control board on my furnace. He clearly explained the nature of the problem, what may have caused it, and the cost to repair. He interacts effectively and gains the confidence of his clients. Mr. Rich efficiently corrected the problem and ensured all of my questions were answered. Thank you for the excellent service!
