Is it better to leave your thermostat at a constant temperature?
The startup process for a furnace consumes more energy than simply running the entire time at one set temperature, costing you additional money. To maximize efficiency, it’s best to keep your furnace (or AC) at the same consistent temperature for long periods of time.
Is it cheaper to keep your house at constant temperature?
Keeping your home at a constant temperature generally means that your HVAC system will run constantly to meet it. This means that your furnace or air conditioner may run when you’re asleep, at work, or out of the house. This wastes more energy than the minimal amount that you might save by having it constantly run.
