When the energy auditor came over for a door test, he used a scanning device around the house to check for leaks. He called a day before and asked us to move all the furniture away from the exterior walls, for the scan.
When he was here, he found most of the leaks on the top of each door frame inside the house and of coarse on the exterior walls. He said that he hasn't been inside a home yet that seals that part up well enough. Some of the doors with adjustable sill plates were leaking until I raised them up.
He did find one wall between the garage and the house that had missing insulation when he scanned it.
Do you have a crawl space? I would love to see how much heat is lost from the floor.
