A residential audit is an assessment of a home to evaluate its energy efficiency and overall performance. This process typically involves examining insulation, heating and cooling systems, appliances, and windows to identify areas where energy is being wasted. The goal is to provide homeowners with recommendations for improvements that can reduce energy consumption and lower utility bills. During a residential audit, professionals may use tools like blower doors and thermal imaging cameras to detect air leaks and heat loss. Homeowners receive a detailed report outlining findings and suggested upgrades, such as better insulation or more efficient appliances, to enhance comfort and sustainability.
