Winterize

This one is a no brainer. For $20 worth of weather stripping you can save a bundle on you heating bills. Try closing up the cracks and gaps around your windows and doors. You will be amazed at what a difference it will make when the cold weather arrives. All sorts of drafts and air leaks can be beaten this way. You don't need to be much of a handyman to use this stuff either. Most of it is peel and stick self-adhesive these days. Couldn't be simpler. If you have window or wall mounted air conditioners, invest in an insulated elastic cover. An awful lot of heat is lost through uncovered AC units in the winter.
