Indoor Air Quality Testing
Full assessment of airborne pollutants, particulates, and allergens inside your property.
The average person spends about 90% of their time indoors, where air can hold several times the pollutant load of outdoor air. Fine particulates, combustion gases, allergens, elevated CO₂, and humidity problems accumulate quietly — showing up as headaches, poor sleep, aggravated allergies, and that persistent "stuffy building" feeling.
Our indoor air quality assessment measures what you're actually breathing. We test across the parameters that matter, review how your HVAC system is performing, and deliver a prioritized improvement plan — from ventilation adjustments to filtration and source control — grounded in measured data rather than guesswork.
Why this testing matters
Health symptoms with no visible cause
Recurring headaches, fatigue, and irritation that improve when you leave the building are classic indicators of an air quality problem worth measuring.
After water, fire, or renovation
Building damage and construction dust change indoor air for months. Testing confirms whether the air is actually back to normal.
Children, elders & sensitive occupants
Asthma, allergies, and respiratory conditions make good air a necessity, not a luxury.
Wildfire smoke intrusion
Southern California fire seasons drive fine particulates indoors, where they linger in ducts and on surfaces long after skies clear.
Workplace comfort & productivity
Elevated CO₂ and poor ventilation measurably impair concentration — a fixable problem in most commercial spaces.
Data before spending
Measurement first means you invest in the fix that addresses your actual problem — not a shelf of air purifiers you may not need.
What's included
- Particulate testing (PM2.5 / PM10)
- CO₂, CO, temperature, and relative humidity measurement
- Allergen and mold-spore sampling as indicated
- HVAC and ventilation performance review
- Source identification walkthrough
- Written report with a prioritized improvement plan
Our process
- 1
Understand the concern
Symptoms, odors, recent events, and building history all shape which parameters we measure and where.
- 2
On-site measurement
We test throughout the occupied spaces — not just one spot — capturing the variation between rooms, floors, and HVAC zones.
- 3
Lab analysis where needed
Samples requiring laboratory work (spores, allergens, targeted pollutants) go to accredited labs.
- 4
Improvement plan
Your report ranks findings by impact and lays out practical fixes — ventilation, filtration, humidity control, and source removal — in the order they'll help most.
Frequently asked questions
How is this different from VOC testing?
IAQ testing is the broad assessment — particulates, gases, comfort parameters, and biologicals. VOC testing zeroes in on chemical off-gassing specifically. Odor or chemical-symptom cases often warrant both; we'll advise honestly on what your situation needs.
Can you test after wildfire smoke got into the house?
Yes. We measure residual particulates and can add smoke-byproduct surface testing to determine whether cleaning and duct work are needed or the levels have already normalized.
Will one bad reading mean expensive fixes?
Usually not. Many IAQ problems resolve with ventilation changes, filtration upgrades, or humidity control — the report is designed to start with the highest-impact, lowest-cost steps.
