Preparing your home for winter is crucial for energy efficiency and comfort. Start by checking your insulation; ensure it's adequate in attics and basements. Seal gaps around windows and doors with weatherstripping to keep the cold air out. Don’t forget to service your heating system to guarantee optimal performance. Additionally, disconnect hoses from outdoor faucets to prevent freezing. By winterizing your home, you can save on energy bills and enjoy a cozy environment during the colder months.
