Where does unwanted heat come from your house?

Unwanted heat in a house can come from several sources, including direct sunlight through Windows, inefficient insulation, and heat generated by appliances and electronics. Poor ventilation can trap warm air indoors, exacerbating the issue. Additionally, factors like cooking, heating systems, and even body heat from occupants contribute to elevated indoor temperatures. Addressing these sources through better insulation, shading, and ventilation can help reduce unwanted heat.
