HVAC as the distribution system
Growth in air handlers, coils, or ductwork does not stay put; it ships spores to every zone the system serves. Assessment includes the mechanical system whenever odor or complaints outrun visible growth — cleaning a wall while the ducts recirculate the problem is theater.
Indoor air quality complaints and employer duty
Employee IAQ complaints create a documentation duty the moment they are made. A dated response chain — assessment, findings, remediation, clearance — is what separates a handled issue from an OSHA-flavored one. We route crews who treat the paper trail as part of the job.
Clearance before reoccupancy
Under Texas Mold Assessment and Remediation Rules (TMARR), projects over the licensure threshold end with clearance evaluation before containment comes down — and even below it, post-remediation verification is what lets you tell staff the air is clean and mean it. Reoccupancy on test results, not on smell.
Questions office teams ask
Who tests air quality after office mold remediation?
An assessor independent of the remediation crew — in Texas, licensed for projects at or above the Texas Mold Assessment and Remediation Rules (TMARR) threshold. Independence is what makes the clearance letter worth the paper.
Can employees work in an office during mold remediation?
Outside the contained work zone, generally yes with managed airflow; inside it, no. Zoned containment and after-hours scheduling keep the floor working while the problem is removed.
