What Is a Blower Door Test?

9 / 9

How much does it cost to get a blower door test done?

You can hire a professional to perform a blower door test and energy audit for approximately $300-$400 for an average sized house. You also have the option to perform your own testing. More and more builders, remodelers, insulations companies, and HVAC companies are choosing to do them in-house. Some municipalities, but not all require a blower door testers to be certified by a HERS Rater or BPI Analyst. Others municipalities only require an IDL ( infiltration duct leakage certificate) or a DET (duct envelope tightness certificate).

A basic blower door starter kit consists of the following:

• Fan/blower
• Frame
• Canvas
• Pressure gauge assembly (color coded hoses and ports to reduce user error)
• Tubing to connect gauge to fan and gauge to outside

The price of a starter kit typically starts around $3000 and goes up from there. You will also need a monitor, smoker and thermal imaging camera. You do have the option to rent these from the manufacture, but this usually happens when larger jobs (commercial buildings) are needing multiple units to do the test.
