I want to thanks Nat and Gavin for the awesome job they preformed at my home. I appreciate the call I received in advance of their arrival. They were very professional, courteous and took the time to answer all my many questions. And didn't make me feel that I was being a problem for wanting to know. Thanks to the company that hire such nice people.

I was so impressed with the professional way Alan and Gavin presented themselves. Alan first by telephone and then personally coming to my door and explaining the procedure they would use to help me save energy. Alan immediately assessed the problems and with much work and time they repaired and tested for efficiency. These two gentlemen were very knowledgeable, showed me what exactly needed to be done, and proceeded with their particular protocol. They completed the job and showed me exactly what they had done and cleaned up like they were never here. I can only think Atmos for having diversified energy send what I consider two of the most professional knowledgeable people to address and fix my energy problems.

Nat, Xavier and Derek with Diversified Energy came out to our home today to do a home performance inspection. These three gentlemen were absolutely the best. They were very knowledgeable very respectful and friendly and did everything with a smile. Their work was excellent, our home is energy efficient now, we can actually feel the difference, it’s a lot cooler. I highly recommend this company and these gentlemen to do your inspection.

Ron and Nat came to my home and did a great inspection, sealing any areas that were “leaky” and “defective”! The house is air tight and the “before and after” measurements were amazing. We are energy efficient now!! Thanks for a great service!

Mary Palmer

00:19 02 Oct 24

Honestly, I was wondering how this assessment would go, what they would do, what we would learn from it, etc., and I was totally impressed! Tron and Nat were so professional and knowledgeable, that by the time they left I was amazed at what I learned about my own house!! And, after they finished sealing everything, and repairing things as needed, my air conditioner really seemed to work better!! It was awesome, and I’m hoping to get some insulation work done by them as well to make it even better. Highly recommended!! Thanks!

Shout out to Phazie and Nikki ! These two arrived on time, ready to work. They were super efficient and professional, they explained the process and how they were going to examine my homes AC system. Before they came my home was getting extremely hot, not cooling off until late in the night. They resealed my AC unit, zip tied all my vents and ductwork, also sealed the gaps on my plumbing. Now my home is staying cool throughout the entire day. These guys or life savers!

Late post but I'm finally getting to it but I just want to say that Niki Aguillard and her helper did a great job in securing my home. They really took their time and extra time fixing problems in and around the attic. Then they both explained to me what they were doing step by step. Thank you both so much!

Michael Powers

Couldn’t be happier with the work they did on my home. It started with a consultation, where the individual was extremely knowledgeable and professional, discussed overall energy optimization for my 1900s shotgun home and what would be the best bang for my buck given my specific home and problems. Really took a wholistic approach to energy efficiency rather than just giving 1 solution. After discussion and some quotes, we ultimately ended up with spray foam insulation in the attic and beneath the floors. I asked a lot of questions and all were answered quickly. The work was scheduled and completely relatively on time with minimal impact to my work schedule (much of it was able to be done without me being present). Upon initial inspection they were not happy with their own work (although i could not tell the difference) and redid a portion on their own dime. The commitment to quality work over getting it done quickly was something i was not used to seeing from contractors, and showed a great deal of ownership and pride in their work. Finally some minor damage was done as they completed and it was addressed quickly and at no cost to me. Overall highly recommend and the final product as exactly what i was looking for, as my home is much cooler and ready for a hot summer.

Niki, Allen, & Tron were such a delight to meet. They were so informative, and particular in explaining to me different questions I had to help me understand thoroughly. They did a wonderful job, and they cleaned up after themselves as well. If you’re looking for the BEST, I highly recommend that you go with Diversified Energy.

They came in and did an awesome job. All smiles, made sure the work was being done effectively, explained everything and gave me a couple pointers. My CFM50 Reduction was almost 2000. A massive drop in inefficiency. They even cleaned up everything behind themselves

Nikki and her crew did an excellent job attending to my home energy needs. From the beginning, Nikki was very communicative letting me know exactly what time the crew would arrive. They were very attentive to details, and made sure to keep me informed of everything that was going on throughout their work. They were even so kind as to let me know I had a roof leak, 😔, and notified me of it's location. They were mindful of my home and made sure not to disturb anything and even offered to help vacuum the house when they were done! They were also very aware, and kind, to my pup while going in and out the house, as he likes to dart around. Nikki made sure my gate and front door were always closed! (For those that have pets home while workers are present know how important this is.) I have had quite a few groups of people work on my home over the years and I can tell when someone cares about their work and when someone doesn't. Nikki and her team really cared, and I felt like I got to know them during the time they were working on my home. What a great job! It was a wonderful, EASY experience to work with them!

Jeff and his team were very informative and helped me to understand the way my AC and insulation were contributing to moisture issues I was having. Through an educational approach, we addressed the most pressing issues and will re-evaluate progress over time. We added spray foam over a previous spray foam job that was inadequately done, corrected damaged duct work under my house with insulation, and replaced an oversized AC unit, all of which were contributing to excess moisture and wasted energy costs in my home.Jeff and team were also very friendly and professional, which was refreshing when I was being oversold and pressured by another company. I would certainly recommend Diversified Air to friends and family.

Diversified Energy did a great job at my home for weatherization. The crew was extremely professional and curious. I would highly recommend this company.

Gary Clements

Diversified Energy, from its owner, Jeff Haag, to its team led by Nikki, were thorough, competent, professional, hard-working and cost-effective. We had our attic ductwork sealed and then the entire attic floor insulated with blown-in cellulose fiber, covered completely by sheets of the cutting edge technology of QV Platinum PCM (Phase Change Material) [Diversified Energy is the sole provider of this technology in the metro area]. Our A/C system works less now, even with continuing heat. We recommend Diversified Energy for upgrading your home’s energy efficiency!!

Jeff Haag and Diversified Energy went above and beyond while consulting with my client about insulation and home efficiency. He is very knowledgeable and has insulated multiple homes for me, always with good results. Very responsive too.

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”

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!

I had such a great experience with Jack, Shamone, and Chad! They were extremely friendly and very professional!
