Energy-efficient: Especially with inverter aircon Singapore models.
Sleek design: Blends easily with modern interiors.
Zoned cooling: You can install multiple units for different rooms.
Cons
Higher installation cost compared to window units.
Requires professional servicing every few months to maintain efficiency.

2. Cassette Aircon: The Stylish Ceiling Solution
What Is a Cassette Aircon?
A cassette aircon is a ceiling-mounted system often used in offices, retail shops, or larger homes. The indoor unit sits flush with the ceiling, distributing air evenly in four directions.
Pros
360° airflow ensures even cooling throughout the room.
Space-saving: No wall clutter, perfect for rooms with limited wall space.
Powerful cooling: Great for open-plan layouts or commercial spaces.
Cons
Complex installation: Needs ceiling space for ducts and wiring.
Higher maintenance cost: Servicing requires more time and expertise.

Cassette aircons suit large living rooms, commercial buildings, and offices that need uniform cooling and a clean ceiling finish.

3. Window Aircon: Compact and Affordable

Pros
Affordable: Lower upfront and installation cost.
Simple setup: Easy to install or replace.
Compact design: Ideal for small bedrooms or temporary setups.
Cons
Noisy: The entire system is in one box, so it’s louder than split types.
Less energy-efficient: Consumes more power over time.

Window aircons are great for tenants or homeowners who need budget-friendly cooling without permanent installation.
