Best Home Energy Audit Services 2026
by Anonymous
Professional home energy audits cost $200-$600 and identify insulation gaps, air leaks, and inefficient systems that waste 25-30% of energy in a typical home. Blower door tests and thermal imaging reveal invisible problems that drive up utility bills. Many utilities offer free or subsidized audits, and federal tax credits can offset efficiency upgrades recommended by auditors.
