Copper pipes connect both units. Since the compressor remains outside, the indoor room stays much quieter. Today’s Split ACs also include several modern features like:

Inverter compressor
Wi-Fi connectivity
AI cooling
Convertible modes
Air purification filters
Self-cleaning function

These features make Split ACs the preferred choice in most modern Indian homes.

What is a Window AC?

A Window AC contains all components inside one compact box. The compressor, condenser, evaporator and cooling fan are fitted into a single unit.

The AC is installed in a window or a wall opening because the compressor remains inside the same unit, Window ACs produce more noise compared to Split ACs.

However, they are Less expensive, easier to install and easier to remove when shifting houses. This makes them popular among tenants and budget-conscious buyers.
