I'm in the process of totally going over my house to save some $ this year in heating costs...Here in SC last jan/feb my heating bills were over $350 for a 2600 sq ft older home and this year the costs are supposed to go up at least 30%.
I'm gonna do the 3M plastic thing on most of the windows and liberally caulk them (most windows haven't opened in years).
Add insulation in attic
weatherstrip my ancient doors
go on a caulk frenzy to all cracks/holes in foundation/brick
setup my automatic thermostat to a lower setting (will probably have to get some rugs to cover some hardwood flooring)
any other suggestions?
