What Is a Blower Door Test?
A blower door test measures the airtightness of your home or building — ultimately showing how well it’s built. By using a powerful calibrated fan mounted in an exterior doorway, we pull air through any leaks in the structure. This test pinpoints hidden gaps and weaknesses in the building envelope that waste energy, raise utility costs, and reduce comfort. It’s a simple, critical step to ensure efficiency, durability, and code compliance.
Why Is Blower Door Testing Important?
Air leakage isn’t just a code requirement — it affects comfort, efficiency, and long-term durability. A tight home means lower utility bills, fewer drafts, better indoor air quality, and compliance with energy codes. For builders, it’s the difference between smooth inspections and costly delays. For homeowners, it’s peace of mind that the home is built to last.
Why This Test Is Required — and Worth It?
Code Compliance:
Simply put, you cannot pass final inspection without a successful blower door test showing the home is under the ACH50 limit. It’s a mandatory step for new builds and many renovations. We help you avoid failed inspections by catching major leaks early and verifying compliance.
Energy Efficiency for Homeowners:
A blower door test reveals where conditioned (heated or cooled) air is escaping. Uncontrolled leaks drive up utility bills and strain your HVAC system. By identifying and sealing these leaks, you can significantly reduce energy waste and lower costs.
Comfort and Health:
A leaky home can mean cold drafts in the winter, hot spots in the summer, and unwanted dust, pollen, or moisture sneaking indoors. Tightening your home’s envelope leads to fewer drafts, better indoor air quality, and improved comfort. It can also help prevent issues like condensation and even pest entry.
Quality Assurance for Builders:
Blower door testing serves as a quality check on construction, verifying that insulation and air sealing were done correctly. We provide a clear, detailed report — an excellent reference for your records and for meeting certifications.
