Program details

How it works

A homeowner signs up, qualifies, and receives a free home energy audit. The auditor tests insulation and looks for problem areas. A utility-approved contractor then prepares a work proposal with recommended improvements and available incentives. Once the proposal is approved, the work is installed, and a quality control inspector reviews the project.

What the money covers

The page describes a comprehensive weatherization program aimed at optimizing energy efficiency and comfort. It does not list every eligible measure, but it says the contractor will outline recommended improvements and incentives after the audit.
