Technician told my wife he could not install a wired thermostat because there was no way to route a new wire that was needed. He installed a wireless thermostat that has been a problem since installation. In a follow-up visit, asked a different technician to look at the wiring and he agreed that the previous technician was wrong and wrote in his visit notes that a wired thermostat could be installed. I signed those notes. Asked for a copy of the visit notes that they always send electronically. Received notes that were not signed by me and the words about the previous technician being wrong were missing. Asked again for the signed notes and have not received a response. I'd done with One Hour Heating after several years. They can no longer be trusted.
