While air sealing is often associated with keeping cold air out during winter, it’s just as important during summer. Tiny cracks and worn weatherstripping allow cool, conditioned air to escape and hot, humid air to seep indoors. This forces your air conditioner to work harder than necessary and increases energy costs.

Take a few minutes to check for drafts, replace weatherstripping and seal leaks. A tighter home keeps you more comfortable and helps manage energy use.
