Choosing between a split and window air conditioner is one of the first decisions when buying an AC. Both have distinct advantages depending on your needs, budget, and living situation.
What is a Window AC?
Window air conditioners are self-contained units that fit into a window frame. The entire system—compressor, condenser, and evaporator—is housed in one box.
Pros of Window AC
- Lower upfront cost: 30-50% cheaper than splits
- Easy installation: No professional help needed
- Portable: Can be moved to different rooms
- Simple maintenance: All components accessible
Cons of Window AC
- Noisy operation (compressor inside room)
- Blocks window and natural light
- Less aesthetically pleasing
- Limited to rooms with suitable windows
What is a Split AC?
Split ACs have two units: an indoor unit with the evaporator and an outdoor unit with the compressor and condenser, connected by refrigerant pipes.
Pros of Split AC
- Quieter operation: Compressor is outside
- Better aesthetics: Sleek indoor design
- More efficient: Higher EER/SEER ratings
- Flexible placement: No window required
Cons of Split AC
- Higher purchase price
- Professional installation required
- More expensive repairs
- Permanent installation
Cost Comparison
Window ACs cost 15,000-30,000 THB for most sizes, while split ACs range from 20,000-50,000 THB. However, split ACs save 20-30% on electricity over time.
Which Should You Choose?
- Choose Window if: Budget is tight, you rent, or need portability
- Choose Split if: You own your home, want quiet operation, or prioritize efficiency
