What is the best temperature settings for my thermostat?
At the lowest (winter) or highest (summer) temperature at which your family is truly comfortable. There is no magic number. The highest purpose of a home comfort system is comfort. If you heat with a heat pump not equipped with a “smart” thermostat, or a programmable thermostat, you should find a comfortable temperature setting and leave it there. With any system, it is easiest to balance comfort and economy with the help of a programmable thermostat.
