Code Compliance Duct & Envelope Testing

Blower Door And Duct Testing Is More Than Just That Energy Efficiency Thing. It Is Testing Beyond Guessing!!

GA. Code Compliance

D.E.T Verifying

Georgia’s Energy Code 2015 IECC + 2020 GA Supplements and Amendments require a blower door and a duct leakage test on new builds and some retrofits, according to GA Code. TruResults Home Services recommends that all new construction be tested before drywall and insulation are completed. Air sealing and adjustments are easier to accomplish before the exterior and interior are completed. Oftentimes, mistakes are made that are very expensive and labor-intensive to correct at the final stage. D.E.T Verifying is a pass or fail test. If a test failed we work with homeowners, builders, and contractors to achieve a passing score.

  • Blower Door Test (Envelope leakage 5% or less) 
  • Duct Leakage Test (Duct leakage 6% or less) 
  • Pass or Fail Report and Recommendations 

Blower Door Testing

Building performance issues may not lie in plain sight. They are often invisible in the final stages of construction or possibly hidden on purpose. During a blower door test, overall air leakage is measured on all six sides of the house. Blower door testing is a major hardship for poor construction because nothing can hide. Stop guessing and let's start testing.

Duct Tightness Testing

Duct testing helps improve energy efficiency, indoor air quality, system performance, and comfort while also contributing to the longevity of your HVAC system. Duct testing measures unintentional leaks in the duct system. HVAC systems are designed to regulate indoor air for comfort, including temperature control and air filtration. A properly designed and well-sealed duct system will provide great comfort and optimize your system performance. However, if it’s not sealed properly, it can allow pollutants in the air stream, waste energy, and inflate your energy bills. This is why air duct leakage testing is crucial. This test can be done at various construction stages or post-construction.

Just Build Tight & Right

At Tru-Results Home Services, we understand the importance of meeting building code requirements. A failed test will delay your Certificate of Occupancy and cost you more money from your budget. Blower door testing is essential for ensuring your building’s airtightness, which is a key factor in energy efficiency standards, comfort, and a healthy home. By identifying and fixing air leaks, you can meet and even exceed these standards, ensuring compliance with both local and state regulations while gaining control of your building’s comfort, efficiency, health, integrity, and performance.

It Doesn't Always Lie in Plain Site..

Simple air leakage can cause your investment a catastrophic failure. Air leaks in building science translate to condensation, humidity, and moisture. They can be observed by dripping, puddling, stains, wicking, rot, and components deteriorating over time.

  • Why is a D.E.T Verifying test necessary?

    It is important to know how your home will operate as a system. Also controlling air leaks  is a big deal.  Blower door and duct testing can help you acheive an A+ Home performance status . D.E.T Verification gives us the ability to bring your Builging envelope and ducts past the local Code Official D + or a D- level of approval.  In new constrution a F+ is the new C+ to meet code enforcement  quality installation acheivement standard. 


  • What does the test consist of?

     D.E.T Verifying consist of the following:

    1.  A walk through inspection of the property

    2. Prepping the home for safety and setup

    3. Run the test.

    4. Provide a comprehensive report 

     *Note: this is a pass or fail test. Tru-Results Home Services have no obligations for failed tests. 


  • What if I failed my code compliance test?

    Code compliance D.E.T Verifying is a pass or fail test. Upon receiving a failed test score, our Techs inspect with test equipment and a brief infared scan to obtain an inspection report. We provide you with a  report to assist in obtaining a passing score. We also offer an extended  test that includes  equipment use, testing and air-sealing. 

     ~Our home performance package starts at $325

  • When should a DET/BET Verification test be performed?

    Testing should be performed on new construction before the finished work is done.  This provides an opprotunity to fix any issues that may cause a fail test. After the finished work is done, (drywall placement and insulation installed), its only a pass or fail test. Trying to receive your certificate of occupancy can be a hardship if your builder is waiting until the last day to test.
