  • Q: How can I become a qualified blower door tester?
  • A: FSEC offers a one-day Residential Building Air Leakage [Blower Door] Testing course, however, this does not guarantee that a local building official will consider you qualified. Blower door testing is only one step towards understanding building science, and testers should consider further education, such as becoming an Energy Rater. FSEC also offers Energy Rater Training.


  • Q: Who is eligible to perform duct leakage tests?
  • A: According to the 2017 Florida Building Code Energy Conservation, Sixth Edition Section R403.3.2 Sealing (Mandatory).
    "All ducts, air handlers, filter boxes and building cavities that form the primary air containment passageways for air distribution systems shall be considered ducts or plenum chambers, shall be constructed and sealed in accordance with Section C403.2.9.2 of the Commercial Provisions of this code and shall be shown to meet duct tightness criteria below.

    Duct tightness shall be verified by testing in accordance with ANSI/RESNET/ICC 380 by either individuals as defined in Section 553.993(5) or (7), Florida Statutes, or individuals licensed as set forth in Section 489.105(3)(f), (g) or (i), Florida Statutes, to be “substantially leak free” in accordance with Section R403.3.3.
    R403.3.2.1Sealed air handler.
    Air handlers shall have a manufacturer’s designation for an air leakage of no more than 2 percent of the design airflow rate when tested in accordance with ASHRAE 193.

    R403.3.3 Duct testing (Mandatory).
    Ducts shall be pressure tested to determine air leakage by one of the following methods:
    1.Rough-in test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the system, including the manufacturer’s air handler enclosure if installed at the time of the test. All registers shall be taped or otherwise sealed during the test.
    2.Postconstruction test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the entire system, including the manufacturer’s air handler enclosure. Registers shall be taped or otherwise sealed during the test.

    Exceptions:
    1.A duct air leakage test shall not be required where the ducts and air handlers are located entirely within the building thermal envelope.
    2.Duct testing is not mandatory for buildings complying by Section 405 of this code.

    A written report of the results of the test shall be signed by the party conducting the test and provided to the code official.

    R403.3.4 Duct leakage (Prescriptive).
    The total leakage of the ducts, where measured in accordance with Section R403.3.3, shall be as follows:
    1.Rough-in test: The total leakage shall be less than or equal to 4 cubic feet per minute (113.3 L/min) per 100 square feet (9.29 m2) of conditioned floor area where the air handler is installed at the time of the test. Where the air handler is not installed at the time of the test, the total leakage shall be less than or equal to 3 cubic feet per minute (85 L/min) per 100 square feet (9.29 m2) of conditioned floor area.
    2.Postconstruction test: Total leakage shall be less than or equal to 4 cubic feet per minute (113.3 L/min) per 100 square feet (9.29 m2) of conditioned floor area."

  • Q: How do I become an Energy Rater?
  • A: Energy Raters are expected to understand a reasonable amount of building science, including:
    • Building pressures.
    • How to test for leaks in ductwork
    • How to ensure the house is safe for testing from any combustion sources
    • How to inspect houses for thermal and air infiltration barriers, and
    • How to conduct blower door testing.
    FSEC is one organization that provides this training. Check out the Energy Rater Training Track.


  • Q: How do I become a Provider for EnspectorPro?
  • A: You will need to Create a Provider
    Note:
    • If you are already logged in as a provider type of user account, the account you're logged in with will be able to select the newly created Provider once it has been approved by an EnspectorPro Administrator.
    Additional Important Notes:
    • You will need a policies URL which is a webpage containing information about your provider's policies regarding QA.
    • You will also need to be manually approved by an EnspectorPro Administrator.
    • Your user account associated with the provider cannot already be a Tester type of account. (We apologize for any inconvenience in this matter)


  • Q: When should a blower door test be performed?
  • A: "Testing shall be performed at any time after creation of all penetrations of the building thermal envelope."

    Exception: Testing is not required for additions, alterations, renovations, or repairs, of the building thermal envelope of existing buildings in which the new construction is less than 85 percent of the building thermal envelope.


  • Q: What are the DEFINITIONS of the approved professionals?
  • A: Definitions are provided by 553.993(5) or (7), Florida Statutes or individuals licensed as set forth in Section 489.105 (1) (2) (3) (f) (g) (i)

  • Q: Why does my PDF report cut off text from the top?
  • A: For best results when printing any PDF file, we recommend using Adobe's PDF Reader software.


  • Q: How come my pressure is showing as positive when I entered it as negative?
  • A: We store all the building pressure numbers as positive numbers to properly reflect the way the numbers are used in calculations.
