3 benefits of installing ducted AC systems for crowded classrooms
Let’s discover what are ducted AC systems!
A ducted air conditioning system uses a central unit to cool or heat air, then spreads it evenly through vents in the ceiling or walls. Unlike a split system that blows air from one unit, ducted AC keeps the whole room steady. So what are the good points of choosing it for crowded spaces?
Keeps everyone comfortable easily
In a room with 30 or more students, the temperature can rise quickly from body heat and sunshine. A ducted AC system keeps the air cool and steady across the whole classroom. This comfort helps students settle in and teachers teach without distraction.
Helps students focus and learn better
When a classroom is too hot, students get sleepy, distracted or restless. In a cool, steady environment, their brains can focus better. For example, in the afternoons when heat usually makes Gold Coast students and teachers sleepy, air conditioning helps keep energy up so lessons run smoother.
Bring healthier air
Ducted systems also filter the air. That means dust, pollen and allergens are reduced. Humidity is also controlled, which lowers the risk of mold and bacteria building up, something that’s really important for students with asthma or allergies.

3 benefits of installing split AC systems for crowded classrooms
Let’s move to split AC systems!
They have 2 main parts: one indoor unit that blows cool air into the room and one outdoor unit that pushes the heat outside. They’re connected by pipes and don’t need any ductwork. Split ACs are usually used for single rooms and are very common in schools, homes and offices.
Direct and fast cooling
Because the indoor unit sits right in the room, a split AC can cool the classroom quickly. This is especially helpful when 30 or more students make the space hot and stuffy. For example, on a summer day, it can bring the room to a comfortable level within 15–30 minutes.
Lower cost to install
Split systems are cheaper and easier to set up than ducted systems. Schools can install them in only the classrooms that get hot, instead of the whole building. For instance, if just a few rooms are crowded, putting split ACs in those spaces saves money while still keeping students comfortable.
Energy efficient
Split ACs only cool the room they’re in, so energy isn’t wasted on empty spaces. Many modern units also adjust power automatically once the set temperature is reached. That means the AC works smarter and uses less electricity over time.

Ducted vs Spilt: What’s the best AC option?
Keeping classrooms cool is not just about comfort, it’s about helping students stay focused and teachers run lessons smoothly. When choosing ducted vs split AC systems, you need to know that each also comes with its own downsides.
Limitations of split AC systems when choosing AC systems for crowded classrooms
- Only cools one room per unit so multiple units are needed for several classrooms.
- Not very effective in large or open spaces like halls or auditoriums.
- Takes up wall space in each classroom and can create a bit of background noise.
- Each unit has its own remote, which can be tricky to manage if a school has many units.
Limitations of ducted AC systems when choosing AC systems for crowded classrooms
- Higher installation costs, especially for older buildings where adding ductwork is difficult.
- Needs enough ceiling or roof space to fit the ducts.
- Not efficient if you only want to cool one or two classrooms, best for large-scale use.
- Maintenance can be more complex if there are leaks or blockages in the ducts.

So when should you choose split AC systems?
Split ACs are a great choice if your school only needs to cool a few crowded classrooms or when budgets are tight. They work well in single rooms and are easy to install without major building changes.
For example: If just three or four classrooms get especially hot in summer, you can simply add split units in those rooms.
So when should you choose ducted AC systems?
Ducted ACs are better for bigger schools where many classrooms, corridors and staff areas need to be cooled at once. They keep the temperature steady across large spaces and run quietly, creating a calmer learning environment.
For example: If most classrooms are packed during summer, a ducted system can cool the entire school efficiently.
Ducted vs split? The right choice depends on how many classrooms you need to cool, your budget and whether your school building can support ductwork. Call DEEPCHILL, your trusted air conditioning Gold Coast to book the best AC systems for crowded classrooms.
