Air-Conditioning & Ventilation Systems Maintenance Checklist

Your HVAC system does more than regulate temperature – it plays a key role in fire safety. Air-conditioning and ventilation systems directly impact how smoke and heat move during a fire, making regular maintenance critical to both comfort and protection. When properly maintained, these systems help prevent smoke spread, support fire control zones, and keep evacuation routes clear.

Over time, filters clog, belts wear, and fire/smoke dampers can fail to close, allowing smoke to travel unchecked. Regular inspection ensures dampers, fans, and control interfaces respond instantly to fire alarms, maintaining air balance and protecting occupants.

Our Air-Conditioning & Ventilation Systems Maintenance Checklist helps facility managers and technicians perform thorough inspections, document compliance, and keep systems working seamlessly with fire safety controls.

What’s Inside the Checklist

Your downloadable checklist includes:

• Monthly Tasks: Filter inspection, fan and blower checks, ductwork condition review, and clearance verification.
• Semi-Annual Inspections: Testing duct smoke detectors, verifying damper operation, and confirming HVAC-fire alarm interface functionality.
• Annual Maintenance: Full system testing with alarm interface, pressure differential verification, and documentation of all findings.
• 5–6 Year Tasks: Complete damper cycling, duct cleaning, and detector recalibration.
• After Fire or Alarm Activation: Damper and detector inspection, system reset, and post-event documentation.
• Maintenance Log: Built-in space for recording all inspection intervals and technician notes.
