I just built a new house and had a Carrier 58mvp120 furnace installed. My installer installed a single stage programable thermostat for the system. Would it be worth it for me to have a multi stage thermostat installed. Is it worth it to put in the infinity thermostat. I don't have a humidifier in the system but do plan to add AC next summer.
