How do I perform an energy audit on my home?

Start with a DIY walkthrough: check for drafts around windows, doors, and outlets with a candle or incense stick. Inspect attic insulation depth and look for gaps. Examine ductwork for visible leaks. Check your furnace filter and water heater age. Many utility companies offer free or discounted professional energy audits that include a blower door test and thermal imaging. A professional audit provides the most accurate results and targeted recommendations.
