How can homeowners benefit from addressing insulation issues?

Homeowners can greatly benefit from addressing insulation issues primarily by decreasing energy bills. Proper insulation acts as a barrier to heat flow, keeping homes warmer in the winter and cooler in the summer. When insulation is inadequate or damaged, it allows heat to escape, leading to an increased demand on heating systems in cold weather and cooling systems in hot weather. This added strain on HVAC systems results in higher energy consumption and consequently higher energy bills. By improving insulation, homeowners can create a more energy-efficient home, ultimately reducing their utility costs.

In contrast, the other options do not reflect the advantages of addressing insulation. Reducing property value is not a positive outcome homeowners seek, and increasing indoor humidity levels could lead to comfort and health issues, rather than benefits. Furthermore, having a colder home in the summer goes against the goal of making a home comfortable, as effective insulation should help maintain a pleasant indoor temperature rather than allowing excessive heat to penetrate during hot weather.
