In Utah, we can get a free audit, with the funny commercials ThermWise program.
From their website:
Step 1: CONTACTE-mail Questar Gas today at In-HomeAudit@ThermWise.com or call 800-695-7375(Monday through Friday from 7:00 am - 5:00 pm) to schedule a home energy audit appointment with one of our experienced Questar Gas technicians.
Step 2: DISCOVERGet ready to learn about your home as our technician completes a thorough assessment that usually takes about 90 minutes. He will check your windows, doors, water flow and attic insulation. He’ll also check the efficiency of your furnace, boiler and water heater. If it has the potential to use energy, he’ll check it out.
Step 3: RESULTSReceive your comprehensive report and start making changes. The audit is a roadmap; you decide what changes to make and when. Some fixes are simple but effective. Turn your water heater down to 120° and you could start saving today!
As usual, here's a great article at the Christian Science Monitor about people who are doing it and saving money, and energy, and *gasp* being a little green.
We did have attic insulation installed last year and used our credit, but I'm scheduling (right now) to have this audit completed. Might as well let an expert tell me what I need to add to the To Do List.
