Home performance refers to how well a house operates in terms of energy efficiency, comfort, and safety. It involves assessing various systems within the home, such as heating, cooling, insulation, and ventilation, to ensure they work together effectively. By improving home performance, homeowners can reduce energy costs and enhance indoor air quality. To evaluate home performance, professionals often conduct energy audits, which identify areas for improvement. This process may include checking for air leaks, assessing insulation levels, and examining appliances. Upgrades based on these findings can lead to a more comfortable living environment and lower utility bills, benefiting both the homeowner and the environment.
