Look For Air Leaks
Here's a tip you may have read about but never tried: On the next windy day, turn off your HVAC system and all fans, and then light a stick of incense and hold it near doors, windows, and outlets on exterior walls. Watch how the smoke drifts — you should be able to see where drafts are costing you money.

Weatherstripping doors and windors gives you one of the best returns on investment you can get. Don't forget other not-so-obvious trouble zones such as fireplaces, attic access, and electrical outlets on exterior walls — all of these need to be sealed up as well.

If incense isn't your thing, another way to discover where you need some more weatherstripping is to have your house pressure-washed. Any gap in the weatherstripping around your windows and doors that will let water in will also let air out as well.
