The New Standard: Is Your Home Leaking Money? As of 2026, Tennessee building codes have reached a new frontier in energy efficiency. Whether you are a builder aiming for a Certificate of Occupancy or a homeowner tired of skyrocketing TVA bills, Blower Door Testing is no longer optional—it's essential. Why Blower Door Testing Matters ASAP: Mandatory Compliance: New code cycles require a maximum air leakage rate (ACH50) that can only be verified through professional testing. Without a passing report, your project doesn't close. Stop the "Invisible" Draft: Air leaks account for up to 40% of a home's heating and cooling costs. We find the leaks you can’t see behind your walls and in your attic. Healthier Air: A properly sealed home prevents humidity, allergens, and Memphis "pollen-season" dust from infiltrating your living space. Instant ROI: Most air-sealing and insulation upgrades pay for themselves in energy savings within 2–4 years. Why Champs Construction? We aren't just inspectors; we are Licensed Contractors. While others just hand you a "Fail" report, we provide the solution. We test, we seal, and we certify.
