I couldn't find anyone to fix my hanging heater unit in the garage. Most places I called didn't even know what a Rezner was. I called KT Mechanical and I was greeted by a friendly guy who immediately knew exactly what I was talking about and needed to check if any of his technicians could come out same day. A tech called me back (John) within 5 minutes and was at the house within 15. He came in, friendly as well, and immediately started poking around and explaining what he was doing while he did it. After about 15-20 minutes the heater came on full force (he cleaned the corroded flame sensor). From first contact to saying goodbye, these guys did a fantastic job. Kudos to John especially. read more
