When you consider that many homes have 30 or 40 of these fixtures, it’s easy to see why researchers at the Pennsylvania Housing Research/Resource Center pinpointed them as a leading cause of household air leaks. Most recessed lights have vents that open into the attic, a direct route for heated or cooled air to escape. Finally, seal air leaks in the rest of the house. Then tackle the basement to prevent cold air that enters there from being sucked into upstairs rooms. Start in the attic, since that’s where you’ll find some of the biggest energy drains.
