"They were extremely prompt in getting back to me regarding the initial rating. During the course of remained in contact with me and guided me through of insulation and HVAC specifications. They were also prompt and extremely thorough during the final HERS rating blower door test. As the general contractor and builder for this project, I was pleased with Total Green Energy services and pricing relative to other contractors used and would recommend them to anyone in need of rating or other energy solutions."

"As a builder and developer, it is critical for us to have qualified and timely consultation and advice to share with our clients. Equally important is the ability to handle testing professionally. With Total Green Energy as our consultant, we were able to achieve results that were even higher than our planned design. Our client ultimately gained thousands in cash rebates."

"I was happy to learn that Total Green Energy Solution was both knowledgeable and helpful in offering ideas and suggestions toward improving my methods and simultaneously satisfying the "Stretch Code" requirement. I plan on using Bijan again as he directed me towards an optimal approach to maximizing efficiency vs cost containment. This culminated in a "Win/Win" situation for my end users and my Companies! ."

" I have worked with many HERS raters and have found Bijan to be the most helpful in the way he responds to phone calls and emails and in conveying information about installation procedures. He was in inspecting the insulation and duct work at the rough inspection and the blower door and duct testing at the final inspection. Most importantly, he was easy to schedule time with and worked within my project schedule so as to not delay the progress of the project."
