Blower Door Testing in Pensacola

Blower Door Testing is like having an MRI performed on your house!

At Air & Energy of NWFL, we understand that in the Pensacola climate—where humidity and sea breezes are ever-present—your home’s comfort and efficiency matter. That’s why we specialize in comprehensive blower door testing throughout the Pensacola, Florida area.

Using state-of-the-art diagnostics, our blower door service measures exactly how much conditioned air is escaping your home through hidden gaps and air leaks. The result? You’ll learn where your building envelope is letting your hard-earned cool air escape, and how sealing those leaks can improve comfort, reduce utility bills, enhance indoor air quality, and help protect your home from moisture- and draft-related issues.

Blower Door Testing is like having an MRI performed on your house!

We’ve been doing blower door testing for over 12 years and have the tools and expertise to help you solve any building science-related concerns.

Air Leakage Diagnostics

Blower Door Testing is the most comprehensive and thorough diagnostic test that can be done on your home to find and fix issues related to dust, humidity, duct leakage, uneven temperatures in rooms, attic insulation, leakage in the building envelope, airflow, ventilation, and more!

Find & Repair Air Leakage

This test is like having an MRI performed on your house! As of July 2017, the State of Florida now requires a Blower Door Test to be performed on ALL new construction.

Questions? Call us.

The purpose is to verify that new homes fall within the Florida Building Code requirement of 3 to 7 Air Changes per Hour (ACH). If a house is too tight it needs “fresh air” or mechanical ventilation to be brought in. If it exceeds 7 air changes the builder is required to tighten the house up via gaps, cracks, and holes until it meets the state's criteria.

  • How to interpret the results of a blower door test?

    The results of a blower door test will be delivered in the form of two readings: CFM50 (leakage rate measured in cubic feet per minute at a 50 Pa) and ACH50 (air changes per hour at 50 Pa).

    The CFM50 reading is taken from the manometer on the conclusion of the test. The ACH50 is then calculated by multiplying the CMF50 reading by 60 (minutes per hour) by the volume of the building (including the basement) in cubic feet and then dividing the number by the building’s volume.

  • When should I get a blower door test?

    The most common time to perform a blower door test is at the final stages of building construction when all wall finishes, fixtures, doors/windows, and appliances have been installed.

    Blower door tests are also commonly carried out to test the airtightness of older buildings. Over time, seals can wear out, and cracks can open up in the structure envelope, which allows an increase in infiltration and exfiltration. If you begin to feel drafts or notice any unexplained increases in your energy bill, you should consider the option of investing in a professional blower door test.

  • What is infiltration/ exfiltration?

    Infiltration is the uncontrolled inward leakage of outdoor air that enters a building through cracks, gaps, and other unintentional breaks in the structure.

    Exfiltration is the opposite—it describes the uncontrolled outward leakage of indoor air from a building through these cracks and openings.

  • Is blower door testing required in Florida?

    As of 1 July 2017, Florida law (Section 402.4.1.2, Florida Building Code, 5th Edition 2014 Energy Conservation) stipulates that all new residential constructions must pass a blower door test to ensure compliance with energy code.

    Specific requirements are that each new home must have 7 ACH50 or less to pass a blower door test. Existing buildings are not subject to this law but reducing a building’s ACH50 reading is recommended to increase energy efficiency and cut down on energy costs.

  • What is the average time that it takes to perform a blower door test?
    The time a blower door test takes depends on the size of the home. Generally speaking, it shouldn’t take longer than 30 minutes or so to complete a blower door test from start to finish. If combined with a whole home audit, the entire process should take approximately 1 - 2 hours.
