These ceiling-mounted units are designed with stylish features that blend seamlessly into interior spaces, making them popular for their sleek design and efficient cooling.


They are ideal for larger rooms and open spaces. Before you make a decision, here’s what you need to know.


What Is a Cassette Aircon?


A cassette aircon is installed in the ceiling, with only a stylish grille visible below. Often featuring a thin body design, it is ideal for installation in confined areas like ceiling cavities or drop ceilings.


It distributes cool air evenly in multiple directions, making it a great choice for spacious areas like living rooms, offices, and retail spaces.


Key Benefits of Cassette Aircons: Energy Efficiency


  • Space-Saving: Doesn’t take up wall or floor space.

  • Even Cooling: Airflow is distributed in multiple directions.

  • Quiet Operation: The main unit is hidden, reducing noise.

  • Aesthetic Appeal: Blends seamlessly into ceilings.

  • Energy Efficiency: Many models use inverter technology to save on electricity bills.

  • High Ceilings: Particularly effective in rooms with high ceilings, as they enhance comfort by ensuring cool air circulates effectively in spacious environments.

Preparing for Installation


Installing a cassette aircon requires proper planning. Here’s what you need to do before installation:

  • Prioritize energy-efficient models with good energy ratings.


3. Installation Considerations


  • Clear furniture and cover items to prevent dust.

  • Ensure proper drainage to avoid water leaks.

  • Check if your home’s wiring supports the unit’s power requirements.

  • Confirm with your condo or HDB management if permits are required.

  • When budgeting for installation, be aware that the listed prices may not include Goods and Services Tax (GST) and additional charges may apply for installation and other services.


Step-by-Step Installation Process


  1. Choose the Best Ceiling Spot – Ensure central placement for even cooling.

  2. Cut the Ceiling Opening – Measure carefully before cutting.

  3. Install the Indoor Unit – Secure the unit properly in the ceiling.
