Thermostat not working. Clown came and said i should install a wireless thermostat $900.00 flat rate or rewire old thermostat same price. I refused so he directly wired the second floor zone so it would make furnace call for heat for both floors. Long story short neither floor worked. Wasted $100.00 for service call. Had Fitz Mechanical come and rewired thermostat for $240.00.
