For Almost 2 Decades, Jeff Haag & Diversified Energy Have Been Providing Home Performance Solutions To The Greater New Orleans & Gulf South Region

Jeff Haag & Diversified Energy have been a part of the Greater New Orleans business community for almost two decades providing home performance diagnostic testing, and home energy efficiency improvements for thousands of customers.

It all started in 1999 when Jeff became one of the first energy efficiency raters in the state of Louisiana. By starting on the home performance assessment side of the business, this experience provided Jeff with unique insight into how a home energy efficiency works as an entire system. And to understand implement energy efficiency improvements that work together to not only lower energy bills, but also increase the overall comfort throughout a home.

Since these humble beginnings, Diversified Energy has expanded to include a wide array of home performance diagnostic testing services, indoor air quality services, and home energy efficiency improvements.

Diversified Energy has also expanded into partnerships with regional & national solar energy companies, non-profit organizations, and electric utility rebate programs to deliver customized energy efficiency solutions for their clients.

How Diversified Energy Is Different Than The Rest

We examine all the performance aspects of your home. We note your insulation levels, air infiltration, and heating/cooling equipment. We perform forced and passive duct leakage tests in order to create a plan to maximize your family’s comfort, increase your home’s energy efficiency, provide cleaner interior air quality, and uncover any potential health and safety concerns.

    Jack, Chad, and Aaron were fast at their task at hand but very thorough in explaining the project. Did not waste any time setting up the equipment and Jack , probably the Team Leader, really know the program by heart.
