Improving your home’s energy efficiency reduces bills and environmental impact. Start by sealing gaps around doors, windows, and ducts to prevent heat loss. Upgrade insulation in walls, attics, and floors. Use energy-efficient appliances, LED lighting, and programmable or smart thermostats to optimize electricity usage. Regularly maintain your HVAC system, including cleaning filters and servicing AC units. Consider installing energy-efficient windows and solar panels where possible. Simple habits like turning off unused lights, lowering thermostat settings in winter, and using ceiling fans in summer also help. Combining these strategies enhances comfort, lowers costs, and promotes a sustainable home.
