One effective way to enhance your home's energy efficiency is by sealing your windows and doors. Start by inspecting the caulking around your exterior window frames and doors. Over time, caulking can deteriorate, leading to gaps that allow cool, conditioned air to escape while letting hot air in. To combat this, consider applying new weatherstripping. This simple step not only helps to maintain a comfortable indoor temperature but also reduces energy costs by preventing air leaks. By ensuring that your windows and doors are properly sealed, you can create a more energy-efficient home environment.
