Before a school district spends money on IAQ upgrades, it helps to know what the HVAC system is doing.
Not what it was designed to do.
That means checking things like:
• Outdoor air delivery
• Filter performance
• Classroom airflow
• CO₂, temperature, and humidity trends
• Whether controls are responding the way they should
Without that baseline, school districts can end up fixing the wrong problem.
Adding more equipment
More airflow
More cost
Yet still the same complaints
