Commercial HVAC mold remediation: define the duct-cleaning scope first.
A report near a register, duct, air handler, coil, or drain pan does not establish where mold is located or how far it extends. TRC scopes mold remediation for coils, drain pans, and air handlers and can perform or subcontract duct cleaning. HVAC shutdowns, operating decisions, and equipment repairs remain separate responsibilities.
A condition reported at a register does not identify the source or the responsible trade.
A visible condition or odor near an HVAC component may involve the duct, nearby building materials, a moisture condition, or mechanical equipment. The location of the report should guide further scoping without being presented as proof of system-wide distribution.
TRC can include mold remediation for coils, drain pans, and air handlers and confirmed duct cleaning in its written scope. HVAC shutdown, restart, operating decisions, and equipment repair should remain with the property's responsible HVAC contractor. Any requested testing remains independent of TRC.
Separate remediation, duct cleaning, mechanical work, and independent testing.
The proposal should identify the responsible party for each scope before work that depends on it begins.
Document the reported location
TRC records where the condition was reported and which accessible areas are included in the requested assessment. A report at one component is not described as proof that the full system is affected.
Confirm who controls the HVAC system
The property's HVAC professional remains responsible for shutdown, restart, operating decisions, and mechanical repairs. TRC does not decide when equipment is ready to operate.
Define TRC's mold and duct-cleaning scope
Work performed to IICRC S520 standards. TRC provides mold remediation for coils, drain pans, and air handlers and may perform or subcontract duct cleaning when it is included in the written scope.
Keep any testing independent
If ownership requests testing, the client may retain an independent company or TRC may arrange one that does not work for TRC. TRC does not sample the air or certify the result.
Provide separate project records
We document losses and coordinate with insurance carriers. TRC's remediation documentation, the HVAC contractor's records, and any independent testing report remain attributable to the party that performed that work.
Bring the system history without treating it as a diagnosis.
These details help separate the mold-remediation request from duct cleaning and mechanical service.
Where the condition was reported
Note the register, duct section, mechanical room, or nearby building material involved. Location narrows the discussion but does not establish the full extent.
When the condition appears
Record whether an odor or visible condition is constant or associated with system operation. That observation is project information, not a species or air-quality conclusion.
Known leak or condensate history
Provide available maintenance records for prior leaks, condensate events, or repairs so the HVAC and remediation scopes can be discussed by the responsible parties.
Who maintains the equipment
Identify the property's HVAC contractor or facilities contact before shutdown, access, repair, or restart responsibilities are assigned.
Commercial HVAC mold-remediation questions.
The carrier decides coverage under the policy and reported cause of loss. We document losses and coordinate with insurance carriers. We bill your insurance directly. Direct billing does not promise coverage.
Yes. TRC handles duct cleaning in-house and through subcontractors. The proposal should identify who performs the duct-cleaning scope for the specific project.
Yes. TRC provides mold remediation for coils, drain pans, and air handlers. The property's HVAC contractor remains responsible for shutdown, restart, operating decisions, and equipment repairs.
The property's responsible HVAC professional and ownership make that decision. TRC does not determine when equipment is ready for operation.
The client may retain an independent company or TRC may arrange one that does not work for TRC. TRC does not perform the sampling or issue a post-remediation determination.
Work timing is confirmed after access, HVAC responsibilities, and the written scope are known; after-hours completion and uninterrupted operation are not promised.
