Indoor Air Quality Service Visit Assessment

This template covers a single IAQ service visit from start to finish: inspection details, environmental readings, visual condition checks, photo evidence, and findings with recommendations. It is designed to document what was observed in the space, not to replace a full engineering study or long-term monitoring program. Use it when you need a defensible record of a complaint response, routine service visit, or targeted follow-up.

Use this template when the main purpose of the visit is indoor air quality, occupant comfort, or source investigation. It is a better fit than a general checklist when you need to record temperature, relative humidity, CO2, PM2.5, and visible indicators like moisture intrusion or HVAC obstruction. If the visit is focused on life safety, fire protection, or a construction site hazard walk, a different inspection form is more appropriate.

The cadence depends on the trigger: complaint-driven visits are documented each time, while routine preventive checks may be weekly, monthly, quarterly, or tied to HVAC service intervals. This template works for both scheduled and unscheduled visits because it captures the date, conditions, and reason for the assessment. For trend tracking, use the same form consistently so readings and findings can be compared over time.

It is typically completed by a facilities technician, HVAC service provider, environmental health and safety staff member, or other trained inspector. The person filling it out should understand how to place the meter, record calibration status, and recognize obvious deficiency indicators such as visible mold, standing moisture, or blocked airflow. If the issue may involve building systems, a qualified HVAC or environmental professional should review the findings.

Yes, it supports documentation commonly used to show due diligence under OSHA general industry expectations and related workplace health programs. It also aligns well with ANSI/ASSP-style occupational health management practices and can support internal corrective action tracking. If the site is foodservice, healthcare, or another regulated environment, you can adapt the findings section to match the applicable hygiene or environmental control requirements.

A common mistake is recording readings without noting where the meter was placed or whether the instrument was calibrated. Another is treating the visit as a yes/no checklist and missing the source condition behind the complaint, such as a wet ceiling tile, clogged filter, or stagnant return grille. Teams also sometimes forget photo notes, which makes later review harder when comparing the deficiency to the recommendation.

Yes, this template is meant to be customized. You can add additional measurements such as air velocity, VOCs, or differential pressure, and you can tailor the visual checks to offices, schools, healthcare spaces, laboratories, or foodservice areas. You can also add site-specific thresholds, escalation rules, or sign-off fields for maintenance and EHS review.

Geotagged photos create a time-stamped record of the area, the meter setup, and the source condition that was observed. That makes it easier to verify the location of the issue, explain the recommendation, and confirm that the same area was revisited after corrective action. Written notes alone often miss the context needed to support a follow-up decision.

Prioritize items that suggest active moisture intrusion, visible mold growth, combustion odors, blocked HVAC airflow, or elevated particulate levels that may affect occupants. Lower-priority items can include minor housekeeping issues or maintenance needs that do not appear to be creating an immediate exposure concern. The template helps separate the deficiency from the recommended action so follow-up can be assigned clearly.
