Yesterday, I had an energy audit from the city of Tallahassee. I didn't do anything wrong. In fact, I requested the audit. Just call 891-4YOU and you can schedule one for yourself. They came out and checked on some stuff then told me some things I already know. They also told me a few I didn't. I had them check the level of insulation in my attic because they have a program where you can add insulation to your attic and they will pay 80% of the cost! You should be able to make your money back in under 6 months from energy savings. I'm going to schedule an appointment with a local contractor to come and spray in more insulation in my attic and it will cost me $77 while the city pays the rest.
The city also gave me a sweet goodie bag. It had a couple 20W (75W equivalent) CFLs, 2 thermometer stickers...yeah, stickers that tell you the temperature, some literature, and a low-flow showerhead manufactured by AM Conservation Group. I installed the new showerhead and it has a ton of pressure.
Anyway, my point is that it's worthwhile to schedule an energy audit, especially if your insulation isn't up to par.
