Local Reviews in Mt Vernon, MO
Friendly and professional.
We had previously contacted Tim about servicing our furnace when we bought a house 3 years ago. At that time, he fixed it the best he could and recommended we think about purchasing a new furnace. He was not pushy nor “salesman” like. He gave us his honest opinion and did not push when we declined at that time. But we felt comfortable enough with his service and information that we knew then that we would be reaching out to him specifically when it was time to do the replacement.
Absolutely recommend.
