First Quality Debunks “Urban Legend” about Winter Thermostat Settings
Some household myths have been around so long and have spread so wildly that they're no longer myths; they've become urban legends. One such legend is that homeowners should not dial down their heat before leaving the house during the fall and winter. The thought is that the furnace will have to work harder to warm your house once you return. The warning is clear: a furnace that works harder will cost you more money to operate, so leave that dial where it is before you walk out the door.
