A Home Energy Audit is an assessment of a home's energy use to identify areas where energy efficiency can be improved. During the audit, a professional evaluates insulation, heating and cooling systems, appliances, and lighting. They may use tools like blower doors and thermal cameras to detect air leaks and heat loss. The goal of a home energy audit is to help homeowners understand their energy consumption and find ways to reduce costs and environmental impact. Recommendations may include upgrading insulation, sealing leaks, or replacing old appliances with more efficient models, ultimately leading to lower energy bills and increased comfort.
