Ventilation System Inspection

Assess the condition and performance of HVAC and ventilation equipment supplying fresh air to occupied spaces.

  • Are all HVAC air supply and return vents free from obstruction?
  • Have HVAC air filters been replaced within the manufacturer's recommended schedule?
  • Is the outdoor air intake free from visible debris, pests, or contamination sources?
  • Is the HVAC system operating and maintaining comfortable temperature ranges?
  • What is the date of the last professional HVAC maintenance service?

Carbon Dioxide & Air Exchange Monitoring

Measure and document CO2 concentrations as an indicator of adequate fresh air ventilation and occupant density.

  • Has CO2 concentration been measured in occupied areas today?
  • What is the measured CO2 level in the primary occupied zone (ppm)?
  • Are windows or supplemental ventilation available in high-CO2 zones?
  • Have occupants reported symptoms such as headaches, fatigue, or difficulty concentrating?
  • Describe any occupant IAQ complaints received in the past 90 days.

Chemical Contaminant Assessment

Identify potential sources of volatile organic compounds (VOCs), cleaning chemicals, and other airborne chemical pollutants.

  • Are all cleaning and chemical products stored in properly sealed, ventilated areas away from occupied zones?
  • Have any new building materials, furniture, or carpets been installed in the past 6 months?
  • Are any photocopiers, printers, or laser equipment located in adequately ventilated spaces?
  • Is there any detectable chemical odor present in occupied areas?
  • Are Safety Data Sheets (SDS) available for all chemicals used in or near occupied spaces?

Moisture, Mold & Biological Contaminants

Inspect for visible moisture intrusion, mold growth, and conditions that support biological contaminant proliferation.

  • Is there any visible mold growth on walls, ceilings, vents, or surfaces?
  • Are there any signs of water intrusion, staining, or leaks on ceilings or walls?
  • What is the current relative humidity level in occupied spaces (%)?
  • Are HVAC drip pans and condensate lines clean and free from standing water?
  • Are restrooms and kitchen areas adequately ventilated to prevent humidity buildup?

Thermal Comfort & Temperature Control

Evaluate whether temperature and humidity conditions meet acceptable comfort standards for occupants.

  • What is the current ambient temperature in the primary work area?
  • Are thermostats functioning correctly and accessible to facility management?
  • Have occupants reported consistent complaints about being too hot or too cold?
  • Are personal heating or cooling devices (space heaters, fans) being used by occupants?

Occupant Awareness & Reporting Procedures

Verify that employees are aware of IAQ concerns and know how to report issues appropriately.

  • Is there a documented procedure for occupants to report IAQ concerns?
  • Have occupants received IAQ awareness information or training in the past year?
  • Is an IAQ contact or building manager identified and accessible to all occupants?
  • Are previous IAQ inspection records maintained and accessible for review?
  • Provide any additional notes or corrective actions identified during this assessment.

Photographic Documentation

Capture visual evidence of IAQ-relevant conditions, deficiencies, and equipment status.

  • Has a photo of the primary HVAC supply and return vents been captured?
  • Has a photo of any identified mold, moisture damage, or visible deficiency been captured?
  • Has a photo of the air filter condition or recent maintenance record been captured?
  • What is the overall IAQ risk rating for this inspection?
