“I was treated more like a friend/neighbor than a customer by Marty. My pilot light went out on a Friday morning and I called for service before they were open and gat an immediate call back and he came right over. Needed a part, it was installed the same day. Next day, pilot went out again and once again,, he came over to see what was needed (Sat.) Need new furnace to be installed on Monday but Marty was concerned for my comfort and told me to call him on Sunday if I needed to and he will come right over. Matt & Nate were very courteous, friendly and helpful. Quickly installed furnace and made sure I understood everything. I recommend this company to everyone I talk to.”
