About Diversified Energy

Diversified Energy – Providing Air Conditioning, Heating, And Home Performance Solutions To The Greater New Orleans Region

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

It all started in 1999 when Jeff became one of Louisiana’s first energy efficiency raters. By starting on the home performance assessment side of the business, this experience gave Jeff unique insight into how home energy efficiency works as an entire system and a deep understanding of how to implement energy efficiency improvements and air conditioning and heating solutions that work together to not only lower energy bills but also increase the overall comfort and indoor air quality throughout a home.

Since these humble beginnings, Diversified Energy has expanded to include air conditioning & heating system installation and repair services, along with a wide array of home performance diagnostic testing services, indoor air quality services, and home energy efficiency and performance improvements.

Diversified Energy’s professional services include:

Air Conditioning & Heating system installation and repair

High-performance insulation for residential and commercial applications

Home performance and energy efficiency improvements

Home diagnostic testing, performance verification, and code compliance services

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

Niki Aguillard and her crew came out to my house and did a fantastic job! They texted me what time they would arrive and they were on time. They made... sure every crack was sealed in my house and even put door sliders on the doors to keep the air from flowing in. They completely insulated the attic. They were very friendly and kind overall did an amazing job I’m very pleased with how they went over and beyond to ease every concern I had and I really appreciate their hard work. Would definitely recommend Diversified Energy “Plug into Comfort”read more

First off these are some friendly and professional people! They came in to our home and had nothing but respect and explained things in a way that... was more family/friend based than technical. BIG shout out to Mike and Ryan for the amazing help and work! They tested the house and did all the checks as well as made sure we had stuff in place. They hooked us up with a great light package that should help our energy use as well as lighting needs. Everything is top notch and amazing customer service!read more
