Duct System

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.

Duct Leakage Testing

TruResults Home Services provides professional duct leakage testing and airflow diagnostics to evaluate the performance of your duct system and identify issues that may be impacting comfort, efficiency, and HVAC operation.

A duct system plays a critical role in how a home heats, cools, and distributes air. Even a high-efficiency HVAC system cannot perform as intended if conditioned air is being lost through duct leakage, airflow restrictions, poor design, or installation deficiencies.

Too often, HVAC equipment is replaced or upsized before the existing duct system has been properly evaluated. While new equipment may be necessary in some situations, replacing equipment without understanding the performance of the air distribution system can leave underlying problems unresolved and, in some cases, create new ones.

Using advanced testing equipment and building science principles, we measure duct leakage, airflow, and system performance to provide objective data about how the system is operating. This information helps homeowners make informed decisions before investing in equipment replacements, duct modifications, or other upgrades.

Technology has advanced beyond rule of thumb diagnosis. Proper testing provides the facts needed to understand system performance and identify solutions based on measurable results rather than assumptions.

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.

Duct Testing, Duct Cleaning & Duct System 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.

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.
