During an energy audit, which system's performance is typically assessed?

During an energy audit, the efficiency of heating and cooling systems is typically assessed because these systems have a significant impact on a home's overall energy consumption. Heating and cooling represent a large portion of a household's energy use, often accounting for 50% or more of total energy expenses. Evaluating their performance involves checking for factors such as insulation levels, ductwork integrity, thermostat settings, and system capacity to ensure they operate efficiently.

This assessment is crucial for identifying areas where energy loss occurs and for recommending improvements that can lead to enhanced energy efficiency, reduced utility bills, and increased comfort within the home. By optimizing these systems, homeowners can significantly reduce energy consumption, making them a primary focus of energy audits.

While plumbing systems, electrical wiring, and structural integrity are important in their own right, they do not directly pertain to energy efficiency in the same way that heating and cooling systems do.
