Weatherization services are designed to improve the energy efficiency of homes and buildings. These services often include sealing gaps and cracks, adding insulation, and upgrading heating and cooling systems. By reducing air leaks and improving insulation, weatherization helps maintain comfortable indoor temperatures and lowers energy bills. Additionally, weatherization services can enhance indoor air quality and reduce the environmental impact of energy consumption. Programs may be available through local or state governments, often targeting low-income households to help them afford necessary improvements. Overall, weatherization contributes to a more sustainable and cost-effective living environment.
