Thermostat was uncalibrated & reading higher than what temperature actually is inside home & rising faster than it should realistically causing heating sequence to cycle on & off faster than how it should. Thermostat was replaced. (T705) Only has heater working. They ended up going with a minisplit for the other side of the house, only furnace works. Completed heating maintenance & will only do heating maintenance when we come out. Signed up for membership Placed yard sign & filled comfort survey.
