Energy Efficiency Auditing FAQs, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.
