Turns out, keeping your interior doors open in winter could actually help your home stay warmer! If you’ve got central return vents, closing doors can mess with airflow and make your heating system work overtime (hello, higher bills). Let that warm air flow freely by leaving doors open, especially bedrooms and bathrooms. But if your place has return vents in every room or zoned heating, you’re safe to close them. Who knew doors could make such a difference? #Home #HomeHacks #WinterTips
