A couple of years ago the furnace was replaced and a new thermostat installed. The new thermostat is identical to the old one. The temperature never reaches the setpoint. Currently the temperature reaches about 70 degrees with the setting at 73. Also the new furnace seems to cycle on and off more frequently than the old one. The new one is a much higher efficiency. Should I try a new thermostat or reinstall the old one? Or just accept the bias? The old one had a wider "span" setting.
