Here are a few tips to help you get started:
1. Check your home for air tightness. On a windy day, hold a lit incense stick next to locations of potential air paths to the outside, like windows, doors, electrical boxes, plumbing fixtures, electrical outlets, and ceiling fixtures. If the smoke blows horizontally, you have found an air leak that can use weatherstripping, sealing, or caulking.
2. Caulk and seal gaps where plumbing, ducting, or electrical wiring penetrate through exterior walls, floors and ceilings.
3. Install rubber gaskets in back of exterior wall outlets and switch plates.
4. Dirty, grimy spots on your insulation can indicate holes where air leaks into and out of your house. Look underneath the insulation batting for holes and gaps and seal them by stapling sheets of plastic over the holes, then caulk the edges of the plastic.
5. In winter, when the fireplace is not being used, keep the flue damper closed tightly. Chimneys are created to allow smoky air to escape, so unless the flue is closed, warm air escapes, and with it, your heating budget.
6. Installing storm windows over single-pane windows or replacing them with double-pane windows is a major savings not to be overlooked. Windows can make up 10% to 25% of your heating bill. Adding storm windows can cut the heat loss in half.
