    • Approved Third Party*
    *Note: An Approved Third Party would be at the discretion of the local Building Official. An entity separate from the builder who is "acceptable to the building official" for the purpose given. [2017 Florida Building Code - Residential, Sixth Edition, Chapter 2]


  • 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: 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.
