Optimization

Duct leakage testing helps improve energy efficiency, indoor air quality, HVAC system performance, and overall comfort while also contributing to the longevity of your HVAC equipment. This test measures unintentional air leaks in the HVAC duct system that can cause energy loss and poor airflow throughout the home.

HVAC systems are designed to regulate indoor air for comfort, including temperature control, airflow, and air filtration. When a duct system are properly designed and sealed, it distributes conditioned air efficiently and helps maintain consistent comfort in every room. However, when ducts are poorly sealed or leaking, they can pull in dust, pollutants, and unconditioned air while wasting energy and increasing utility costs.

Professional Duct Leakage Testing

TruResults Home Services offers expert duct leakage testing and airflow diagnosis to determine how this system can and will perform. Atlanta area homeowners are plagued with horrible HVAC contractors that just box swap or use high static pressures as a sell pitch to meet a quote. The duct system must be evaluated. So expecting a new $15,000 upsized HVAC to do the job only creates a worse issue and only benefits the company in meeting their financial goals. Before replacing a existing system or doing system upgrades the system should be performance tested. Technology has out grown the rule of thumb diagnosis.

The Ductwork Is Your Home's Circulatory System

Duct leakage testing identifies where air is being lost within the duct system and measures how much leakage exists. With proper testing and diagnostics, these issues can be corrected through duct sealing and system optimization. A tight, properly functioning duct system improves HVAC performance, increases energy efficiency, and helps maintain consistent comfort throughout the home.

TruResults Home Services provides professional duct leakage testing and HVAC airflow diagnostics throughout Central Georgia to help homeowners and builders improve comfort, efficiency, and indoor air quality.


Testing, Cleaning & Optimization

“Our duct services begin with duct leakage testing to diagnose issues. If needed, we offer thorough duct cleaning, and for more extensive problems, we provide duct renovations and adjustments. Whether it’s diagnosing, cleaning, or optimizing airflow, we ensure your system runs at its best every step of the way.”


Duct Leakage Testing

Duct systems return air to the heart of the home’s HVAC system. When ducts leak inside the building envelope, it leads to wasted energy, comfort issues, pressure imbalances, indoor air quality concerns, and potential moisture or mold problems.

While cleaning flex ducts is often not recommended, we begin with a thorough inspection. We evaluate your duct system to determine if cleaning is appropriate and safe. If so, we proceed with a professional cleaning process. After cleaning, we make any necessary adjustments and perform a final duct leakage test to ensure the system is performing at its best.

Duct renovations & Adjusments

When duct leakage testing reveals significant issues, we offer a full duct renovation solution. This may include reworking duct layouts, replacing damaged sections, upgrading insulation, and fine-tuning airflow. Proper airflow is essential for system efficiency and home comfort, so once the adjustments are made, we test everything to ensure your system is performing at its best.

D.E.T Verifying

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


 D.E.T Verifying(Duct and Envelope Tightness) Verifying is required in new constructions and retrofits projects to meet energy efficiency and local code compliances. This is a pass or fail test that evaluates both the ductwork and the building envelope for air tightness, ensuring that any leakage is within acceptable limits or targeted goals. By performing a D.E.T Verifying Test, builders and homeowners can identify potential problem areas that may compromise the building's energy efficiency comfort and indoor air quality. The test not only aids in compliance with state regulations but also enhances the overall comfort and longevity of the building by preventing unwanted air infiltration and energy loss. If the building does not pass the test, TruResults Home Services collaborates with stakeholders to implement solutions that will help achieve a passing score and ultimately, a more efficient and comfortable living space.

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


TruResults Home Services, emphasizes the importance of conducting these tests before the completion of drywall and insulation. Early testing allows for adjustments and air sealing, preventing costly and labor-intensive corrections at later stages. D.E.T. (Duct and Envelope Tightness) Verifying is a pass or fail test designed to meet these standards. If a test fails, TruResults works with homeowners, builders, and contractors to achieve a passing score.

 Failing a test could delay obtaining a Certificate of Occupancy and inflate project costs. Blower door testing is a key component in achieving airtightness in building standards which is crucial for meeting and exceeding energy efficiency standards.

By identifying and repairing air leaks, builders can ensure compliance with local and state regulations, enhancing the building’s comfort, efficiency, health, and structural integrity.


  • 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.
