Indoor Air Quality Testing

EHS Analytical Solutions provides comprehensive indoor air quality assessments for commercial, industrial, and institutional facilities throughout California. Our certified industrial hygienists don’t just test the air—we investigate root causes, evaluate building systems, and provide actionable recommendations to resolve your air quality concerns.

Whether you’re dealing with employee complaints, unexplained odors, or concerns about ventilation effectiveness, we deliver the expertise and analytical data you need to protect occupant health and maintain a safe workplace.

When to Call Us

Our clients typically contact us when they experience:

• Odor complaints from employees or occupants (musty, chemical, or unidentified odors)
• Allergy or respiratory symptoms reported by building occupants
• Visible mold growth or suspicion of mold contamination
• Ventilation concerns including inadequate air circulation or HVAC performance issues
• VOC concerns from building materials, renovations, or off-gassing
• External contamination sources that may affect your building’s air intake (neighboring operations, exhaust stacks, construction activities)
• Cross-contamination risks between manufacturing/laboratory areas and office spaces
• Post-water damage concerns about lingering air quality issues
• Tenant or employee complaints requiring professional documentation
• Due diligence assessments for property transactions or lease negotiations

How We Help

Our approach combines technical expertise with practical problem-solving:

Root Cause Investigation: We don’t just identify what’s in the air—we determine why it’s there. This includes evaluating HVAC systems, building pressurization, potential contamination pathways, and external sources that may impact indoor air quality.

Ventilation System Assessment: We assess whether your building’s ventilation system effectively manages air quality, including identifying if contamination from manufacturing or laboratory areas is reaching office spaces, or if building air intakes are positioned where they may draw in contaminated air from exhaust stacks or external operations.

Comprehensive Analysis: Our certified industrial hygienists use calibrated sampling equipment and accredited laboratories to provide accurate, defensible data on airborne contaminants.

Actionable Recommendations: We provide practical solutions tailored to your facility, including engineering controls, operational improvements, and feasible mitigation strategies.

Detailed Reporting: You receive comprehensive reports documenting our observations, findings, sampling methods, analytical results, and prioritized recommendations.

What We Test For

Our indoor air quality assessments can identify and quantify:

• Mold and Moisture: Airborne mold spores from water damage or high humidity. (For visible mold growth or suspected mold contamination, see our dedicated Mold Testing services.)
• Volatile Organic Compounds (VOCs): Off-gassing from building materials, paints, adhesives, furniture, cleaning products, or manufacturing processes
• Particulates and Dust: Respirable dust, construction debris, renovation particles, or outdoor pollution infiltration
• Chemical Contaminants: Industrial processes, laboratory operations, cleaning products, or hazardous materials
• Carbon Dioxide and Carbon Monoxide: Inadequate ventilation, combustion appliances, or high occupancy levels
• Airborne Allergens: Dust mites, pollen, pet dander, or other biological contaminants
• Asbestos Fibers: From deteriorating building materials or renovation activities
• Ventilation Effectiveness: Fresh air supply rates, air exchange, and HVAC system performance

Our Process

1. Initial Consultation
We discuss your concerns, building history, and occupant symptoms to develop a targeted assessment strategy.

2. Site Inspection
Our certified industrial hygienists conduct thorough visual inspections, evaluate HVAC systems, identify potential contamination sources, and assess building conditions.

3. Air Sampling
We collect air samples using calibrated instruments, following established protocols for the contaminants of concern.

4. Laboratory Analysis
Samples are analyzed by accredited laboratories using appropriate analytical methods.

5. Comprehensive Reporting
You receive detailed reports including findings, laboratory results, health risk assessments, photographic documentation, and prioritized recommendations.

6. Remediation Support
We provide guidance on implementing recommendations and can conduct post-remediation verification testing to confirm effectiveness.

Frequently Asked Questions

Who do you serve?

We work exclusively with commercial, industrial, and institutional clients including office buildings, manufacturing facilities, warehouses, laboratories, schools, medical offices, retail spaces, and business operations. We do not provide residential services.

Not sure if you need Indoor Air Quality or Industrial Hygiene services?

If your concerns involve specific employee exposures to known or suspected workplace hazards—such as welding fumes, solvents, silica, formaldehyde, asbestos, noise, or other occupational health hazards—our Industrial Hygiene Services may be more appropriate. Industrial hygiene focuses on evaluating specific job tasks and worker exposures, while indoor air quality assessments address general building air quality concerns affecting all occupants. Contact us and we’ll help determine which service best fits your needs.

How long does testing take?

Site inspections and sampling typically take 2-4 hours depending on building size and scope. Laboratory turnaround time is typically 3-7 business days, with expedited options available for urgent situations.

What areas do you serve?

We serve clients throughout California, with primary focus in San Diego County, Orange County, Los Angeles County, and Southern California. We also travel statewide for larger projects.

Do you provide remediation services?

No, we maintain independence as consultants. We assess conditions and provide recommendations, but we do not perform remediation work. This ensures our findings and recommendations are objective and in your best interest.
