When is it necessary to clean the HVAC system following a fire?

Cleaning the HVAC system following a fire is necessary when the inspection reveals damage because the presence of smoke, soot, and other contaminants can compromise the system's functionality and air quality. An inspection will typically look for residue, blockages, or other signs of damage that may have resulted from the fire. If these issues are detected, it indicates that the system could be circulating harmful particles throughout the environment, which can pose health risks and further complicate restoration efforts. Cleaning the HVAC is crucial for ensuring that it operates efficiently and maintains a safe indoor air quality post-fire.

While a professional recommendation is important—especially in evaluating the need for cleaning—the determination must be based on the inspection findings that confirm damage. If the system was operating during the fire, it may raise concern, but it doesn’t automatically necessitate cleaning unless the inspection substantiates that concern. Damage classification as light does not exclude the possibility of needing cleaning; therefore, the decision should hinge on inspection results rather than the extent of damage alone.
