Jeremy: Thank you for sending. As I mentioned to you on Thursday, I appreciate your attention to detail. This report is excellent, and as per your physical inspection, I appreciate the detail in the report.
Peter Denver, CO
Don't know what we'd do without your thoroughness. Your detailed reports & other information has helped immeasurably while working with our builder and HVAC company to have our HVAC system problems corrected.
Thank you for your work and the information and professionalism.
Judy Denver, CO
Andy, Jeremy - I just wanted to let you know I didn't have any questions or concerns with the Audit or HES reports.
Tom Denver, CO
Andy, Thank you, I knew the energy audit would be worth the cost when we first talked. I did not realize how much you did and everything that was checked. Your detailed report was easy to understand, I had never considered several of your comments about leakage and energy loss expense.
Peter Aurora, CO
Have you seen this yet? Wow....what a great report, just stating the facts, with no opinions in the building science of this home.
This is what every house needs, and btw...every new home gets a blower door test, air sealing, etc. because of these principles.

As the owner of an older home in Denver facing high utility bills, I was looking for an expert opinion on how to make my home more energy-efficient. I hired Andy and Jeremy from e3 Power to do an energy audit through the Denver Energy Challenge program.

I just wanted to thank you for your participation with the Denver Energy Challenge and as an Xcel approved home energy auditor. You are extremely knowledgeable and it showed during the audit. This is also reflected in the audit report which is very well done.
I was very impressed by the thoroughness of your report and that you were very nice to work with.

Andy, Thank you for your detailed report and the valuable time you spent with me on the phone and Taylor in the condo. It's a great learning experience. Hopefully we can make a dent in the energy consumption and heating situation!
Thank you for supporting the participation of Andy Wildenberg in the U.S. Department of Energy's Multifamily Job Task Analysis (JTA) Workshop for Building Operator, held on May 9-11, 2013 in Golden, Colorado.
Also, I wanted you to know that I was able to reduce the heat after you insulated and still be very comfortable - so thanks for the good work. Thanks for your help.
Steve came and did my assessment which was absolutely fabulous. I learned a lot! Thanks to all of you for providing such a wonderful service.

First, thank you for a very professional, and exceptional job. We have had a couple of very positive remarks on the job you and Steve did in the crawlspace of the house. I would also like you to know that if you ever need a testimonial Bob and I would be very happy to do so.

We first contacted Andy Wildenberg, owner of e3 Power, through their advertisement on the Internet. We asked Andy to do an energy audit for our 34 year-old house in Indian Hills.

[Andy] and [Steve] were professional, comprehensive in their study of our energy use and our building, and thorough in their explanations of what we have achieved and what we can achieve in terms of efficiency and energy use.
