Affordable Energy Now is the way to go if you want to determine any areas of concern with energy loss. They are a professional company there to help you create a "plan of attack" to get your home, energy efficient. A great part is they are not trying to sell you a specific product so you get unbiased facts. Another company offered free home audit, I had them come in they were selling specific product and that just happened to be what I needed. The other company pointed out one window that was of poor energy quality...the worst in the house. When affordable energy came out and setup equipment, that window showed to be very well sealed.
