My wife recently watched a bunch of shows on TV about how to do your part to make sure your house isn’t wasting energy. She was immediately ready to call in some kind of expert to go through our house from top to bottom and tell us what we were doing wrong. I have weatherized our house, but I was willing to humor her and call in the expert since she said it could help us save money on heating and cooling costs. But I was not willing to let just any stranger into our house. I did some calling around and it turns out that you should look to find someone who has received an energy auditor certification do this job for optimal results.
