Cassette type air conditioners are a preferred option among homeowners, businesses, and interior designers for cooling large public areas. These aircons can uphold the design of a sophisticated space. Cassette air conditioners not only provide a sleek look unlike wall-mounted air conditioning systems, but they are also effective, powerful, and energy efficient in both residential and commercial spaces. Are you are thinking about getting a cassette type aircon? Let’s discuss the installation procedures, costs, maintenance, and everything in between.
What Is a Cassette Aircon?
Cassette air conditioners are ceiling-mounted units that distribute conditioned air in four directions. This feature makes the aircon suitable for open areas like offices, restaurants, modern homes, and conference rooms. The units are usually set into a false ceiling with only the cover showing.
Cassette air conditioners are split aircon systems. Both the evaporator and the indoor unit are placed in the ceiling, whereas the condenser unit is located outside of the building.

Benefits of Installing Cassette Type Air Conditioners
Cassette air conditioners have their own unique benefits. Below are the reasons why you should install a cassette type aircon:
1. Aesthetic Integration
If you have a beautifully designed ceiling as part of your interior design, then cassette ACs are the best option. They remain invisible to all eyes when mounted onto the ceiling.
2. 360° Air Distribution
Most cassette aircon models provide cool air in all directions. They eliminate any chances of warm areas within the room.
3. Space-Saving
These air conditioners are perfect for spaces with unconventional floor plans since they don’t require space on the wall for mounting the aircon.
4. Quiet Operation
They are usually quieter than wall mounted aircons. Therefore, they are referable for sleeping rooms and offices.
5. Powerful Performance
They provide very efficient cooling for big rooms. They perform well even when the room is full of people.
Where to Install Cassette Air Conditioners
To choose the right location for cassette type aircon, you can follow below tips:
- Central Location: Install the unit in the center of the room for even air distribution.
- False Ceiling: Cassette ACs must be mounted in a false ceiling. You must have a false ceiling before installation.
- Avoid Obstacles: There should not be obstacles such as lights, beams, or ceiling fans near the aircon.
- Service Access: There should be enough space around the unit for maintenance and cleaning of the unit.

Step-by-Step Guide to Cassette Aircon Installation
Below is the step by step process of installing a cassette type aircon:
Step 1: Site Inspection and Planning
Before anything else, an HVAC technician will inspect the ceiling structure to assess whether it can take the indoor unit’s weight. Additionally, he’ll check if there’s enough space to accommodate the unit.
Step 2: Ceiling Preparation
The technician will cut an opening in the false ceiling according to the indoor unit’s dimensions.
Step 3: Install Indoor Unit
Lift the indoor unit into the ceiling. Secure it with brackets or ceiling rods. Make sure the unit is perfectly level.
Step 4: Connect Drainage
Attach the drain pipe to the designated port. Make sure there’s a downward slope to allow the water flow inward direction.
Step 5: Connect Copper Pipes
Run copper refrigerant lines between the indoor and outdoor units. Insulate both the suction and liquid lines to prevent energy loss and condensation.
Step 6: Wire the Units
Connect the power supply and control wires from the indoor unit to the outdoor condenser.
Step 7: Install Outdoor Unit
Mount the outdoor unit on a flat surface like a balcony, wall bracket, or ground-mounted slab. Ensure good ventilation and avoid direct sunlight if possible.
Step 8: Vacuum and Test
Use a vacuum pump to remove moisture and air from the copper lines. This step is critical to ensure better performance and longevity of the aircon components.
Once vacuuming is done, open the refrigerant valves and use a manifold gauge to check pressure levels.
Step 9: Final Testing
Power on the system and test the aircon’s performance. Check airflow, temperature, and drain function. Listen for unusual noises and check for refrigerant leaks.
Step 10: Close Ceiling Panel
Finally, if the aircon is running smoothly, close the ceiling panel.
The installation is now complete.
How Long Does It Take to Install a Cassette Air Conditioner?
The installation time generally takes 4 to 8 hours. Total installation time depends on:
- Site accessibility
- Ceiling structure
- Distance between indoor and outdoor units
- Electrical and piping complexity
- Type of installation – commercial or residential
