When You Should Consider an IAQ Assessment
An indoor air quality evaluation is often helpful when:
-
Occupants experience unexplained symptoms (headaches, fatigue, irritation, or respiratory issues) that improve when away from the building
-
Persistent odors, stuffiness, or “stale” air are present
-
Recent renovations, new furnishings, or chemical use have occurred
-
Humidity problems, poor ventilation, or condensation are noticeable
-
A real estate transaction, tenant concern, or employee complaint requires documentation
-
You want baseline data or verification after changes to the building or HVAC system
-
Sensitive individuals (children, elderly, or those with allergies/asthma) occupy the space
Proactive IAQ assessment helps protect health, comfort, and property value.

Frequently Asked Questions
Is this the same as a mold inspection?
No. Our dedicated mold inspection page focuses specifically on fungal growth and moisture sources. IAQ assessments take a broader look at overall indoor air conditions, which may include chemical, particulate, and comfort factors in addition to biological concerns when relevant.
Do you perform remediation or sell air-cleaning products?
No. SouthTech Environmental Group provides independent assessments and testing only. We do not offer remediation, cleanup, or product sales.
Can you test for specific chemicals or particles?
Yes. We select appropriate sampling and measurement methods based on the concerns identified during the assessment.
Do you serve both homes and businesses?
Yes. We provide IAQ services for residential properties and commercial facilities throughout our service area.
