Fire Damper Inspections

The inspection and testing of fire and smoke dampers are critical for safety. These dampers are designed to minimize and stop a fire inside an HVAC system, which can help protect both the people within the building and minimize the damage to the structure itself.

Fire and smoke dampers can often collect foreign materials and particulates such as dirt, combustible dust, and debris. These contaminants can impair the proper function of dampers, leaving the building occupants at risk in the event of a fire. Other times, the dampers may be obstructed, damaged, painted over due to new construction. The damper could also have issues with poor hinges or parts, misalignment, bent tracks, rust, damaged frames or blades, resulting in an inoperable actuator.

The mandatory NFPA standards require fire damper inspections 1 year after their installation, then every 4 years after that (except for hospitals, where they must be inspected every 6 years).  The standards also detail specific and mandatory requirements on how the inspections must be conducted and documented. By having an expert perform your required fire damper inspections, you can ensure that all NFPA standards are met.

At Carolina Filters, we provide clients with the highest level of client satisfaction when it comes to inspecting these fire dampers and ensuring that they are in peak working condition. Our team is fully trained and certified to provide clients with Fire Damper inspections. Our services include the following:


We inspect all fire, smoke, and fire/smoke dampers to ensure that their performance is in accordance with the NFPA 80 Standard and NFPA 105 Standard as well as The Joint Commission requirements. These standards and requirements are in place to ensure that each component of the system works optimally.


Testing is important to ensure that the system is in top working condition. At Carolina filters, our fire damper testing procedures include:

  • Operating all dampers to verify they fully close and re-open
  • Checking all damper components to ensure they operate properly
  • Labeling each damper to show the number and the inspection date
  • Documenting any deficiencies
  • Digital photos of the dampers opened and closed
  • Ensuring that dampers are digitally located on Life Safety Drawings, as requested

Our Fire and Smoke Damper reporting system makes it easy for clients to monitor and document how well their damper system is working. Our system offers comprehensive records so that each client can monitor their system and know when it is time for the next scheduled inspection.
