Can I Turn Off My Furnace During Winter if I’m Going on Vacation?
Turning off your furnace during winter when you’re going on vacation can be a good idea, but it’s essential to take certain precautions to prevent damage to your home and the furnace itself. If you plan to be away for an extended period, consider setting your thermostat to a lower temperature, around 50°F to 60°F, instead of completely turning off the furnace. This will help prevent pipes from freezing and keep your home warm enough to prevent moisture buildup and potential damage to your home’s structure.
