Excellent. Luke was the Energy Auditor assigned to my home. He was very knowledgeable about building science, the interconnection of various systems in the home (e.g., ventilation, plumbing, indoor air quality), the cause-and-effect interactions of these systems on one another, and the impact of indoor air quality on human health. For example, most of 2019, I had unseen mold issues most of 2019 which negatively impacted my health. This was a result of poor construction on a remodeled home I purchased in November 2018. After much trial-and-error, my own research, x-rays, an MRI, and 7 various contractors, I had mold remediation by another company completed in October 2019. This involved partially exposing the flat roof attic joists and fiberglass insulation that was installed in January 2019. Luke visited my home on October 16, 2019, for a comprehensive energy audit. During his visit, he noted that the exposed fiberglass insulation was improperly installed and could potentially lead to moisture and mold issues down the line. Although the resolution would basically involve tearing down the ceiling, removing the insulation, and installing a new ceiling, I am confident in the advice Luke provided because it coincided with independent research I'd conducted on building science, energy efficiency, and green homes. Home Energy Medics was one of the few companies I've contacted that understand the home is many interrelated systems, is able to articulate this, and has the tools and technology to support their recommendations and observations.
