A home energy audit shows where your home loses energy and which upgrades to do first. Many utility insulation and heat pump programs ask for one. This page lists all 231 HERS rating companies on RESNET's 2026 list in the states we cover, by state, with the 81 we could match to a rated Google Maps listing ranked first.
RESNET's list covers companies that completed HERS Ratings in 2025. Most also do energy code testing and new home certifications; ask whether they audit existing homes and whether your utility accepts their report.
Before you pay for an audit, read which utilities offer their own assessment.
