If you’ve never had a blower door test done on your home, you’re not alone. Many homeowners don’t realize how valuable this simple test can be in improving comfort, lowering energy costs, and even enhancing indoor air quality.
Blower door testing is one of the most effective—and overlooked—ways to ensure your home is operating at its best. Let’s take a closer look.
What Is Blower Door Testing?
A blower door test is a diagnostic tool used to measure how airtight your home is. During the test, a powerful fan is temporarily mounted into an exterior door frame. When turned on, the fan pulls air out of the house, lowering the indoor air pressure. This causes outside air to seep in through any gaps, cracks, or leaks in your home’s envelope. Specialized gauges then measure how much air is leaking, giving a clear picture of your home’s air tightness.
Why Are Blower Door Tests So Important?
Energy Savings Through Leak Detection
Leaky homes are expensive to heat and cool. When air escapes through cracks in your attic, basement, windows, or walls, your HVAC system has to work overtime to keep up. That means higher utility bills for you. Blower door testing reveals these hidden leaks so you can seal them and prevent costly energy loss.
Increased Home Comfort
Drafts and uneven temperatures are common in homes with air leaks. You might find that one room is always chilly in winter or too warm in summer. Blower door testing helps identify the source of these issues so you can make targeted improvements that result in a more consistently comfortable living space.
Better Indoor Air Quality
Air leaks don’t just let air out—they also let pollutants in. Dust, allergens, moisture, and even outdoor contaminants can enter your home through unsealed areas. This is especially concerning if you or your family members have allergies or respiratory conditions. By identifying and sealing air leaks, you’re helping to keep your indoor environment healthier.
Moisture Control and Mold Prevention
When warm, humid air enters your home through leaks, especially in cold weather, it can condense and create moisture problems behind walls or in insulation. Over time, this can lead to mold growth and even structural damage. Blower door testing can help catch these issues early before they become costly repairs.
How Often Should You Get a Blower Door Test?
We recommend having a blower door test performed:
- When buying or selling a home
- Prior to major renovations or window/door replacements
- When building a new home (required by code)
- If you notice drafts, uneven heating/cooling, or rising energy costs
