The significance of routinely inspecting and maintaining HVAC systems in schools cannot be understated. It is crucial for creating secure, cozy, and effective learning environments for both employees and students. Schools have to approach this task responsibly to ensure the equipment runs effectively and dependably throughout the school year, and create the best conditions for the educational process. To do it correctly, they must follow special upkeep guidelines and fully adhere to the standards. In this guide, we’ll look at these regulations, required steps, and best practices implemented by HVAC professionals.
Importance of School HVAC Maintenance
According to the Environmental Protection Agency (EPA), one of the top 5 environmental threats to human health is poor indoor air quality. It can contribute to allergies, asthma flare-ups, respiratory problems, and increased absence due to these factors. Poor IAQ also creates conditions that interfere with learning and concentration. In contrast, good IAQ supports students’ well-being and enhances focus.
Maintaining indoor air quality (IAQ), which has a direct impact on students’ health and performance, requires a well-functioning Heating, Ventilation, and Air-Conditioning (HVAC) system. When it works correctly, this system:
- Improves air circulation and ventilation
- Lowers levels of airborne bacteria and viruses
- Reduces the amount of irritants like dust and allergens
- Helps control odor
- Reduces indoor pollutants buildup
The Role of Preventive School HVAC Maintenance
By employing preventative maintenance to monitor your school’s HVAC system, you can identify issues before they arise. This way, you can dodge the problems that require costly repairs. In general, routine maintenance, cleanliness, and a clear exhaust system allow schools to:
- Prevent major breakdowns by addressing issues right away
- Maintain clean ventilation pathways for consistent airflow
- Avoid unexpected malfunctioning
- Reduce repair and replacement costs
As you can see, schools need to pay attention to preventative maintenance for educational facility HVAC equipment because it has a significant impact on system performance and air quality.
Benefits of Preventative HVAC Maintenance for Schools
When pointing out the importance of preventative HVAC maintenance, we already mentioned some of the beneficial features of this service. Let’s take a look at more advantages that it can bring to educational facilities.
- Enhances the Quality of Indoor Air
Indoor air pollution is 2 to 5 times higher than outside air pollution. Higher concentrations of CO2, mold, pesticides, asbestos, and lead residue from building materials can all be found in indoor air. People who suffer from asthma, allergies, rhinitis, or other respiratory issues should avoid these substances due to the risks of their condition getting worse. Of course, completely healthy students and teachers shouldn’t be in such an environment either. That’s why you need to ensure the proper upkeep of your air conditioning and heating system, which will increase the quality of air in halls and classrooms.
- Improves the Comfort and Creates Encouraging Conditions for Learning
The building’s temperature, noise level, humidity, and ventilation all affect how comfortable people feel. This might sound exaggerated. However, a classroom with the proper humidity and temperature can be more favorable to learning, in addition to being healthier. HVAC preventive maintenance might even boost teacher productivity and student achievement.
- Lowers the Cost of Energy
Depending on the building, the HVAC system is usually responsible for around 40–60% of the overall energy consumption. This same equipment with functional issues uses even more energy. For instance, air conditioning can consume up to 10–20% more energy than normal due to a dirty condenser. A properly operating HVAC system deals with air ventilation and heating more effectively and faster. You save money and consume less energy as a result.
- Prevents Long-Term and Expensive Breakdowns
Preventing lengthy malfunctions with expensive repairs is another benefit of HVAC maintenance for school facilities. Up to 95% of malfunctions can be avoided with regular maintenance that keeps HVAC systems running at their best when money is limited. This helps you avoid the expense and bother of unplanned maintenance as well as breakdowns. Remember that the cost of school HVAC replacement will always be higher than the upkeep expenses.
- Prolongs the Life of the Equipment
With regular upkeep and attention to equipment condition, you can prolong the life of your school HVAC system. It can survive years longer if you maintain it clean and adjusted regularly.
How to Maintain School HVAC Systems
The ASHRAE “Design Guidance for Educational Facilities: Prioritization for Advanced Indoor Air Quality” is a useful resource for school districts to understand required maintenance and equipment verification. To help building operators confirm that equipment is operating properly, the guideline includes work checklists, offers suggestions, and cites other information sources.
The guideline divides school HVAC maintenance tasks by priority levels, making it easier to distinguish the importance of certain operations and develop an effective maintenance plan. Let’s look at these tasks by each level.
Prerequisite HVAC Maintenance Tasks
Understanding the existing circumstances and risk tolerance is necessary before beginning any upgrades. This entails several tasks.
- Creating an IAQ Improvement Strategy. Establish specific goals and evaluate the current building systems to determine priority areas.
- Ventilation Verification. To guarantee that the system operates as intended throughout zones, it requires ventilation verification (also known as testing, adjusting, and balancing, or TAB) of the HVAC components. Gathering thorough information, such as drawings, manuals, and control system details, helps create a precise image of the operational systems on the site.
- Determining Airborne Transmission Risk.To establish performance objectives and determine an acceptable level of airborne transmission risk, a formal risk assessment should be carried out.
Very High Priority Tasks
After the preparation phase, the guide offers the most important steps that must be taken right away to improve IAQ since they provide the greatest immediate impact.
- Filtration Improvement. Upgrading recirculated air filtration to at least MERV 13 and making sure there is little air bypass around the filters are the top priorities.
- High-Risk Area Controls. High-risk places, such as K–12 nurse/health suites, require extra care. These rooms should serve as isolation spaces to maintain negative pressure and 12 air changes per hour (ACH).
- Classroom and Assembly Air Distribution. Air distribution in these areas needs to be managed to prevent direct circulation between occupants, reduce drafts, and guarantee good mixing.
- Clean Air Delivery Targets. Using central HVAC or additional air cleaners, the guide recommends aiming for 4-6 equivalent air changes per hour (clean-air delivery) in classrooms.
High Priority Tasks
The next stage concentrates on monitoring, system enhancements, and supplementary technologies. This entails such high-priority tasks as:
- IAQ Monitoring. Install IAQ sensors and compile the information on a platform to produce an IAQ profile for the entire facility.
- Ventilation System Improvements. Make sure your system upgrades adhere to ASHRAE Standard 62.1’s ventilation standards for suitable ACH and outdoor air introduction.
- Classroom-Level Air Cleaning. Utilize portable HEPA units when central HVAC isn’t able to provide adequate clean air.
- Additional Tasks. Enhancing toilet exhaust and air filtration, educating facility employees, and taking into consideration UV-C/UVGI (Ultraviolet Germicidal Irradiation) as a cutting-edge solution to lower airborne germs are additional crucial steps.
Medium Priority HVAC Maintenance Tasks for Schools
Although they are less urgent or can be carried out over a longer period of time, these steps are advantageous for IAQ, comfort, and energy efficiency.
- Humidity Management. By regulating humidity levels, installing humidification and dehumidification systems improves comfort and indoor air quality.
- Energy Efficiency Controls. Maintain good IAQ without excessive energy waste using energy-efficiency offset control techniques.
- Natural Ventilation Support. Use operable windows as an addition to central ventilation. To prevent drafts and unpredictability, coordinate them with the central HVAC system.
