What’s the most common mistake people make in trying to save energy around the house?
Common mistakes people make include:
- letting the furnace or air conditioner salesperson sell them a unit that’s much bigger than they need,
- not getting the ducts checked for leakage when installing a new heating and cooling system,
- thinking that “since heat rises, we only need to insulate the attic.” Floors over a basement or crawlspace, walls and windows also matter.
