Indoor Air Quality (IAQ) Testing VOCs, Formaldehyde, Mold & Organic Dust Inspection / Consulting Services

Dallas, Houston, Austin Indoor Air Quality (IAQ) Testing for VOCs, Mold, Formaldehyde, Organic Dust


ScanTech checks the following key indoor air quality level indicators and can give rapid answers onsite – no waiting for lab results in most cases. (radon testing and mold sampling are some exceptions)

*EFFECTIVE January 1st, 2019 ScanTech will no longer perform residential testing OR consulting for homeowners / tenants – all services are COMMERCIAL ONLY. Here is a page for resources to common questions – CLICK HERE.

We have been testing formaldehyde in the Dallas – Fort Worth area for years and DO NOT require cutting into your laminate floor or charge $525 – $600 per sample and then make you wait for results like some laboratories.


  • Formaldehyde (HCHO) – non-destructive testing – immediate results
  • VOCs (Volatile Organic Compounds) including benzene, toluene
  • Carbon Dioxide (CO2) – general measure of ventilation quality
  • Carbon Monoxide (CO) – deadly gas
  • Respirable Dust Particles in PM2.5 (fine) and PM10 (coarse) size regimes
  • Oxygen Levels (where applicable)
  • HEPA Filtration, MERV rating and other air purifier efficiency metrics
  • Relative ventilation levels – critical to know in newer buildings that are built “tight” for energy efficiency

  • Mold Assessment Consulting (MAC licensed by the State of Texas)
  • Radon Rn-222 Levels (known alpha emitter lung carcinogen)
  • Forensic laboratory field testing (air grab, bulk, tape lift, swab / wipe, etc.) where required for bacterial, viral issues
  • Particulate counts by size channel: 0.3 um, 0.5 um, 1.0 um, 2.5 um, 5 um, 10 um
  • Ozone gas levels and hydrogen sulfide (associated with sewer gas leaks)
  • Positive / negative air pressure checks to confirm tendency for contamination

along with atmospheric factors such as:

  • Temperature
  • Relative Humidity
  • Barometric Pressure (to judge whether the structure is under positive or negative pressure with respect to the outside air)

and for commercial applications such as HVAC metrics, we can also measure:

  • Absolute Humidity
  • Dew Point
  • Mixing Ratio
  • Vapor Pressure
  • Heat Stress (WBGT) & Heat Index Factors

(my personal favorite is Icelandic, very refreshing with a pH of 8.4 which is somewhat alkaline and has a very slight sweet mineral taste)

    Wanting to know what your charge is to test the formaldehyde levels in my travel trailer? I live in Ft. Worth.

  2. EMF Testing Indoor Air Quality Consultant says:

    Mr. Gonzalez,

    I do test for formaldehyde as well as other VOCs, mold and indoor air quality, but due to demand for my services, my rates and clientele are now all commercial.

    I need the indoor air quality tested in my apartment for Formaldehyde and VOC’s. I had to move to a hotel because I was nauseous and had headaches. Can you help me ASAP?

    • EMF Testing Indoor Air Quality Consultant says:

      Mr. Tinker,

      Per the announcement at the top of this page, I only accept air quality testing and other environmental / biomedical / electromagnetic survey projects for commercial customers. Please follow the link in the announcement to find possible alternatives to your scenario.
