Back to School HVAC

As the summer break comes to a close, it’s time to prepare your primary school for the much-awaited back-to-school opening. One of the most critical aspects of this preparation is creating a safe and healthy learning environment for our students and staff. One key factor that often goes unnoticed but has a significant impact on the well-being of everyone in the school is indoor air quality (IAQ) and the proper functioning of the HVAC system. This article will provide facility managers with a comprehensive checklist to ensure optimal a well-maintained HVAC system and optimal IAQ for a successful back-to-school opening.

1. Back-to-School HVAC Inspection and Maintenance

Before the school reopens, perform a thorough inspection of the HVAC system. Ensure that:

  • All filters are cleaned or replaced. Dirty filters reduce airflow, leading to decreased IAQ and potential HVAC system malfunctions.
  • The ventilation system is inspected and cleaned of any debris or blockages that might hinder airflow.
  • HVAC ducts are checked for leaks and sealed appropriately to prevent air contamination.
  • Thermostats are calibrated accurately to maintain a comfortable temperature.

2. IAQ Testing and Monitoring

Install or utilize existing IAQ monitoring systems to keep track of air quality throughout the school year. Monitor and maintain records of key parameters, including:

  • Particulate Matter (PM) levels: Dust, pollen, and other airborne particles can impact respiratory health.
  • Carbon Dioxide (CO2) levels: Proper ventilation is essential to prevent stuffiness and maintain alertness.
  • Volatile Organic Compounds (VOCs): These can be released from various materials and affect air quality.
  • Temperature and humidity levels: Ensure they are within the recommended ranges for comfort and health.

3. Ventilation Improvements

Enhance ventilation in classrooms and common areas to improve IAQ:

  • Consider installing air purifiers with HEPA filters to remove airborne pollutants and allergens.
  • Promote natural ventilation by opening windows and doors when outdoor air quality is acceptable.
  • Implement an HVAC schedule that allows for increased fresh air intake during non-peak hours.

4. Regular Custodial Cleaning and Maintenance

A clean environment is vital for good IAQ:

  • Regularly clean all surfaces, especially those prone to accumulating dust and dirt.
  • Keep carpets and rugs clean and vacuumed with high-efficiency filters to reduce allergens.
  • Maintain cleanliness in storage rooms to prevent mold growth.
  • Regularly clean and sanitize restrooms and other high-traffic areas.

5. Mold Testing and Prevention

Mold can significantly affect IAQ and cause health issues:

  • Inspect and address any water leaks or water damage promptly to prevent mold growth.
  • Ensure proper ventilation in areas with high humidity, such as restrooms and kitchens.
  • Educate staff on identifying and reporting potential mold issues.

6. Green Spaces and Plants

Consider incorporating indoor plants into the school environment:

  • Some indoor plants can naturally improve IAQ by absorbing certain pollutants.
  • Ensure proper maintenance and watering to prevent mold growth in the soil.

7. Educating Staff and Students

Create awareness among staff and students about the importance of IAQ:

  • Educate everyone about the benefits of a healthy indoor environment on academic performance and well-being.
  • Encourage staff and students to report any IAQ concerns promptly.


By following this comprehensive checklist, facility managers can ensure that their primary school is well-prepared with optimal indoor air quality and a functioning Back-to-School HVAC system ready for opening. A healthy and safe environment not only improves learning outcomes but also fosters a positive and enjoyable atmosphere for students and staff alike.
