What is a Blower Door Test?
A blower door test is a diagnostic procedure performed by a certified professional to identify air leakage in a building. The test simulates a 20-mile-per-hour wind blowing on the top, the bottom, and all sides of a home or building. Wherever air can enter through gaps, cracks, or other voids, it will.
The blower door test can help you identify:
- Areas where air is entering or exiting your home
- Opportunities for air sealing
- The amount of air leakage in your home
- Whether your home is within the recommended flow standard
The blower door test is an important tool for improving the energy efficiency of your home. By identifying and sealing air leaks, you can reduce your energy bills and improve your comfort.
How Does a Blower Door Test Work?
A blower door test is performed by a certified professional. The professional will install a blower door in an exterior door or window. The blower door creates a negative pressure inside the home, forcing air to leak out through any gaps or cracks.
The professional will then use a smoke pen or other tool to identify the areas where air is leaking. They will also measure the amount of air leakage in cubic feet per minute (CFM).
The results of the blower door test will be used to make recommendations for air sealing upgrades. These upgrades can include caulking, sealing around windows and doors, and weatherstripping.
Why is a Blower Door Test Important?
Air leaks can waste energy and make your home less comfortable. A blower door test can help you identify and seal air leaks, which can lead to:
- Lower energy bills
- Improved comfort
- Increased indoor air quality
- Reduced noise levels
Who Should Get a Blower Door Test?
Anyone who wants to improve the energy efficiency of their home should consider getting a blower door test. This is especially important for homes that are drafty or that have high energy bills.
Blower door tests are also required for new construction homes in many areas. This is because air leaks can lead to moisture problems and other issues. A blower door test is a valuable tool for improving the energy efficiency of your home. If you are looking for ways to save money on your energy bills and improve your comfort, consider getting a blower door test.
