The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

The three levels of home energy audits include:

Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
