Blower Door Testing For Homeowners
If your home feels drafty, unevenly heated, or expensive to keep comfortable, a blower door test helps pinpoint why.
A blower door test measures how much outside air is leaking into your home. By depressurizing the house, we can identify where conditioned air is escaping and where unconditioned air is getting in—often through places you can’t easily see.

What Homeowners Get Out of It
Clear answers about energy loss
Leaky windows and doors, poorly sealed attics, aging insulation, rim joists, and hidden gaps all contribute to wasted energy. A blower door test helps identify the source of those leaks rather than guessing.
Improved comfort
Air leaks are often the reason for cold rooms, hot upstairs spaces, or drafts in the winter. Sealing them can make your home feel more consistent and comfortable year-round.
Lower energy bills
When heated or cooled air stays inside where it belongs, your HVAC system doesn’t have to work as hard—often leading to noticeable savings over time.
A focused alternative to a full energy audit
Full energy audits can be useful, but they’re not always necessary. If your primary goal is to understand where air and heat loss are happening, a blower door test delivers targeted, actionable insight without the complexity or cost of a comprehensive audit.
This test gives you practical information you can act on—whether that means sealing, insulating, or prioritizing upgrades more confidently.
