- WholeHome Members get a science-backed look at total home performance. This assessment starts with a blower door test that pinpoints air leaks by putting your home under negative pressure. We use smoke puffers and thermal imaging to find gaps, use flow hoods to measure air flow, inspect your attic and crawl space for insulation challenges, and we test for air duct leaks, ensuring comfort is delivered throughout your home. All findings are analyzed using cutting edge software, and you get a full report with data, photos, and clear recommendations. That means smarter upgrades, better air quality, and real energy savings.
