Complaint clusters
Symptoms or odors concentrated by room, floor, tenant area, time of day, or HVAC operating period.
Commercial Property & Facility Support
Respond to tenant air complaints, moisture concerns, and building-health questions with a clear investigation and action plan.
We confirm the scope, location, and appropriate specialist support before scheduling.

Methods, criteria & technical scope
Building-health questions
Occupant complaints are operational problems as well as technical ones.
Persistent odors, headaches or irritation, hot and cold calls, visible water damage, musty conditions, construction dust, tenant concerns, and recurring HVAC complaints can affect confidence, leasing relationships, productivity, and risk decisions. The first objective is to define where, when, and under what operating conditions the problem occurs.
Moisture events
Roof or plumbing leaks, condensate problems, wet porous materials, high humidity, and suspected concealed damage.
Ventilation & pressure
Outdoor-air delivery, distribution, exhaust, filtration, operating schedules, pressure relationships, and contaminant migration.
Renovation & source control
Dust, VOCs, coatings, adhesives, cleaning chemicals, pest-control products, loading areas, generators, and adjacent activities.
Standards & guidance
There is no single federal OSHA indoor air quality standard.
Specific OSHA contaminant or ventilation requirements may apply when a regulated workplace hazard is identified. General building investigations more often require a combination of applicable ASHRAE ventilation and thermal-comfort standards, EPA and NIOSH guidance, lease or owner criteria, and careful comparison with outdoor or unaffected conditions. Mold work may also be governed by state or local licensing rules. Prudence states the role of each criterion instead of presenting guidance as law.
How we investigate
Read the building, the timeline, and the measurements together.
Complaint mapping
Interview stakeholders and map locations, timing, symptoms or odors, occupancy, maintenance history, and changes preceding the concern.
Building walkthrough
Evaluate occupied areas, mechanical spaces, outdoor-air intakes, supply and return paths, exhausts, moisture indicators, housekeeping, and potential sources.
Targeted measurements
Select CO₂, CO, particulate matter, temperature, relative humidity, TVOC screening, formaldehyde, pressure, airflow, moisture, or laboratory sampling only where it advances a defined hypothesis.
Trend analysis
Where conditions are intermittent, continuous logging can reveal relationships to occupancy, HVAC schedules, outdoor conditions, or activities that a spot reading would miss.
Mitigation
Correct the pathway—not merely the reading.
Recommendations may include source removal or isolation, ventilation balancing, schedule changes, filtration improvements, exhaust repair, pressure correction, intake relocation, moisture-source repair, drying or removal of damaged material, construction containment, housekeeping changes, and follow-up monitoring. We define how each high-priority action should be verified.
