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.
