DIY Home Energy Audit
Find Air Leaks
Hold a lit incense stick near windows, doors, outlets, and recessed lights. If the smoke moves horizontally, air is leaking.
Check Insulation
Attic insulation should be 12-15 inches deep (R-38 to R-49 in most climates). If you can see the floor joists, you need more.
Inspect Ductwork
Feel along duct joints for escaping air. Seal with mastic and foil tape.
Window Check
Single-pane windows lose 10x more heat than insulated walls. If replacement isn't in the budget, use window film kits ($3-$5 per window).
