HVAC & Air Duct Quality Testing

Your HVAC system can either support a healthy indoor environment or quietly spread contaminants throughout the entire home. If the system is dirty, leaking, improperly designed, holding moisture, or pulling air from unwanted areas, it can contribute to elevated particulates, microbial growth, poor humidity control, and indoor air quality complaints.

At Building Performance Solutions, we do not just look at the ductwork. We evaluate how the HVAC system is performing as part of the entire building system.

What This Testing Looks For

Our HVAC and air duct quality testing is designed to identify conditions that may negatively impact the air you breathe, including:

  • Dirty or contaminated duct systems
  • Air leakage in the ductwork
  • Poor filtration performance
  • Pressure imbalances affecting the home
  • Moisture issues within the HVAC system
  • Biological buildup in ducts, air handlers, or coils
  • Poor airflow distribution or comfort issues
  • System deficiencies that may worsen dust, odors, or indoor air quality symptoms

Why HVAC Systems Matter So Much

Many indoor air quality issues are not caused by one single source. They are often made worse by the HVAC system continuously circulating dust, insulation fibers, microbial fragments, and other airborne debris throughout the home.

If a duct system is leaking, drawing from unconditioned spaces, or operating under poor pressure conditions, it can introduce contaminants from attics, wall cavities, garages, or other hidden areas. In some homes, the HVAC system is not just part of the problem, it is the delivery mechanism.

What May Be Included in This Evaluation

Depending on the property and concerns, testing may include:

  • Visual inspection of accessible HVAC components and ductwork
  • Airflow and system performance testing
  • Static pressure and pressure relationship testing
  • Filter, coil, and air handler inspection
  • Humidity and temperature readings
  • Identification of visible deficiencies or contamination concerns
  • Evaluation of duct leakage or return-side issues
  • Targeted air quality testing tied to HVAC operation

Common Reasons Clients Request This Service

Homeowners commonly reach out for HVAC and air duct quality testing when they are experiencing:

  • Ongoing dust issues
  • Musty or stale odors
  • Rooms that feel humid or uncomfortable
  • Allergy-like symptoms indoors
  • Concerns about mold or microbial contamination
  • Recent renovation, water damage, or HVAC replacement
  • Concerns that the HVAC system may be making the air quality worse

Our Approach

We approach HVAC and air duct quality testing from a building science perspective. That means we look at the relationship between the HVAC system, pressure, filtration, moisture, airflow, and the building enclosure , not just whether the ducts look dirty.

This allows us to identify underlying causes, not just symptoms.

When This Service Is Especially Valuable

This testing can be especially valuable for:

  • Homes with persistent indoor air quality complaints
  • Occupants with sensitivities to dust, mold, or poor air quality
  • Newer homes with comfort or pressure imbalance issues
  • Older homes with aging duct systems
  • Post-remediation or post-cleaning verification
  • Buyers wanting a better understanding of HVAC-related air quality concerns before purchase
