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 energy efficiency raters in the state of Louisiana. By starting on the home performance assesment 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 permance 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.

    Customer service was absolutely outstanding! The entire crew of Chad, Marc, Fredrick, and Dedrick were the best! They all displayed a high level of professionalism and were very knowledgeable. I had a lot of questions as to what the affects of the weatherization would be outside of just the "lowering of my energy costs." The entire team went into great detail of how the HVAC system works and how this process would impact it. They also gave me some great tips as to how to maximize my energy savings going forward when using my units. You can tell that these guys take pride in their work. They were punctual, timely, and most of all very neat. Upon their completion there is no sign s of them being here, as everything is how it was when they arrived. They were also very respectful to all of the items that were present in my home. Some things had to be moved for access and they all treated my items as if it was their own. You just don't come across this level of great customer service often anymore. I would highly recommend not only this service but this crew in particular to anyone. I am referring 4 other family members for this service and I'll be sure to specifically request this crew! Great job guys and keep up the great work!
