Q: We recently had our house inspected and repaired to save money on our heating and cooling bills. We were promised savings if we would let the company insulate, add new windows and tune up our furnace. Even though this has been a mild winter we have not noticed a significant savings and, in fact, the last electric bill was about the same as last year's bill. We are senior citizens and were given a seniors' discount, but I'm starting to think it was all a waste of money. Am I expecting too much too soon?
