Run a Home Energy Audit
Before you fix anything, find out where your money is actually going. A home energy audit — either professional or DIY — identifies your biggest waste points in order of impact. The U.S. Department of Energy estimates a professional audit costs $100–$400 and identifies improvements that typically save 15–30% on energy costs.
