How can I prevent hot air from escaping or cold air from entering my home?

To prevent hot air from escaping or cold air from entering your home, you can:

1. Seal any gaps or cracks around doors and Windows with weatherstripping or caulking.
2. Install insulation in walls, floors, and ceilings to maintain a consistent temperature.
3. Use draft stoppers at the bottom of doors to prevent air leakage.
4. Upgrade to energy-efficient Windows and doors.
5. Close curtains or blinds at night to trap heat inside.
6. Use a programmable thermostat to regulate temperature efficiently.
