What Is a Split Type Air Conditioner?
A split type air conditioner is a cooling system composed of two main components: an indoor unit and an outdoor unit. The indoor unit houses the evaporator coil and blower fan, while the outdoor unit contains the compressor and condenser coil. These two units are connected by refrigerant pipes and electrical wiring.
How It Works
- Heat Absorption: The indoor unit absorbs heat from the room air through the evaporator coil.
- Heat Transfer: The refrigerant carries the absorbed heat to the outdoor unit.
- Heat Release: The outdoor unit releases the heat into the outside air.
- Cooling Cycle: The cooled refrigerant returns to the indoor unit, repeating the cycle.
This process ensures consistent cooling without the need for large ducts, making split systems ideal for homes, offices, and small commercial spaces.

Types of Split Type Air Conditioners
1. Wall-Mounted Split Type Aircon
The most common type, wall-mounted units are installed high on a wall and are perfect for bedrooms, living rooms, and small offices. They are affordable, easy to install, and energy-efficient.
2. Ceiling Cassette Aircon
Installed in the ceiling, these units distribute air evenly in four directions. They are ideal for large rooms, restaurants, and conference halls.
3. Floor-Mounted Split Aircon
These units are installed near the floor and are suitable for spaces with limited wall or ceiling space. They provide strong airflow and are easy to maintain.
4. Multi-Split Air Conditioning System
A multi-split system connects multiple indoor units to a single outdoor unit. It’s perfect for homes or offices with multiple rooms requiring independent temperature control.
5. Inverter Split Type Aircon
Inverter technology allows the compressor to adjust its speed based on cooling demand, resulting in significant energy savings and quieter operation.
Advantages of Split Type Air Conditioners
Energy Efficiency
Split type air conditioners, especially inverter models, consume less electricity compared to traditional window units. They maintain consistent temperatures without frequent on-off cycles.
Quiet Operation
The compressor is located outside, reducing indoor noise levels significantly. This makes split systems ideal for bedrooms and study areas.
Aesthetic Appeal
With sleek designs and compact indoor units, split air conditioners blend seamlessly with modern interiors.
Easy Installation
Unlike central air systems, split type aircons require minimal ductwork, making installation faster and less invasive.
Improved Air Quality
Many models come with advanced filters that remove dust, allergens, and bacteria, ensuring cleaner indoor air.
Disadvantages of Split Type Air Conditioners
While split systems offer numerous benefits, they also have some drawbacks:
Higher Initial Cost: The upfront cost is higher than window units.
Professional Installation Required: Improper installation can affect performance and efficiency.
Maintenance Needs: Regular cleaning and servicing are essential to maintain optimal performance.
Limited Portability: Once installed, the unit cannot be easily moved.
Key Features to Consider in 2025
1. Inverter Technology
Inverter compressors adjust their speed automatically, reducing energy consumption by up to 60%. This feature is now standard in most 2025 models.
2. Smart Connectivity
Wi-Fi-enabled air conditioners allow remote control via smartphone apps. Users can adjust temperature, set timers, and monitor energy usage from anywhere.
3. Air Purification Systems
Modern split aircons include HEPA filters, ionizers, and UV sterilizers to improve indoor air quality.
4. Eco-Friendly Refrigerants
R32 and R410A refrigerants are replacing older, ozone-depleting gases. These new refrigerants are more energy-efficient and environmentally friendly.
5. Self-Cleaning Function
This feature prevents mold and bacteria buildup inside the unit, extending its lifespan and maintaining air quality.
6. Energy Efficiency Ratings
Look for models with high Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER) ratings. The higher the rating, the more efficient the unit.
Choosing the Right Split Type Aircon
Step 1: Determine Room Size
The cooling capacity of an air conditioner is measured in BTU (British Thermal Units). The larger the room, the higher the BTU required.
Room Size (sqm) | Recommended BTU |
10–15 | 9,000 BTU |
16–25 | 12,000 BTU |
26–35 | 18,000 BTU |
36–45 | 24,000 BTU |
46–60 | 30,000 BTU |
Step 2: Consider Energy Efficiency
Choose inverter models with high SEER ratings to reduce electricity bills.
Step 3: Evaluate Noise Levels
Check the decibel (dB) rating. Units below 40 dB are considered quiet.
Step 4: Check Brand Reputation and Warranty
Opt for brands with strong after-sales support and at least a 5-year compressor warranty.
Step 5: Budget and Features
Balance cost with features like smart control, air purification, and self-cleaning.
