Missing insulation in attics or walls primarily leads to lower energy efficiency. Insulation serves a crucial role in regulating temperature within a home by preventing the transfer of heat, which means that in winter, the desired heat stays inside, and in summer, unwanted heat is kept out. When insulation is inadequate or absent, homes are likely to experience greater temperature fluctuations.

This lack of adequate insulation means that heating and cooling systems must work harder to maintain comfortable indoor temperatures, resulting in increased energy consumption. Consequently, homeowners may notice a rise in their utility bills due to ineffective thermal management.

Inadequate insulation can also lead to issues such as increased drafts, discomfort in various parts of the home, and a higher likelihood of moisture-related problems, which can further degrade energy efficiency and overall comfort. Overall, proper insulation is essential for maintaining energy efficiency and minimizing costs associated with heating and cooling a home.
