Arrived on site for a no heat. We did a Homecare in December and system was working well until yesterday when the thermostat went blank and they couldn’t restore heat. Upon arrival we got the tour of the property and identified the switch for the furnace was turned off. Once power was restored we checked all system operations and overall system performance. Once we confirmed there were no faults or failures, we stayed to let the house warm up a bit and collected our discounted service call fee. System fully operational, call complete.
