Auto & Domestic Air Conditioners – new units, installation, and servicing
A single compact unit installed in a window or wall.
Contains compressor, condenser, and evaporator all in one.
Best for small rooms.
Pros: Low cost, easy installation.
Cons: Noisy, not very aesthetic.
Has two units: indoor (evaporator) & outdoor (compressor).
Connected by copper pipes and refrigerant lines.
Pros: Quiet, energy efficient, looks neat.
Cons: Costlier installation.
Subtypes:
Single-split (one indoor + one outdoor)
Multi-split (multiple indoor units on one outdoor unit)
Uses a variable-speed compressor motor.
Adjusts cooling according to temperature, saving energy.
Pros: High efficiency, stable temperature, low electricity use.
Cons: Higher upfront cost.
(Inverter technology is used in split, window, and other ACs.)
Freestanding unit that can be moved from room to room.
Exhaust hose goes out through a window.
Pros: Mobile, easy setup.
Cons: Noisy, less efficient.
Ceiling-mounted type (used in offices, showrooms, restaurants).

Pros: Portable within the room, strong air throw.
Cons: Takes floor space, costly.
Uses ducts to deliver cooled air through vents in each room.
Common in large homes, malls, hotels, and offices.
Pros: Even cooling, aesthetic (no visible units).
Cons: High installation and maintenance cost.
VRF / VRV Systems (Variable Refrigerant Flow/Volume)
Advanced multi-split system used in big buildings.
Multiple indoor units connect to one outdoor unit with variable refrigerant flow.
Pros: Energy efficient, flexible temperature control.
Cons: High initial cost, needs skilled installation.
Used for large complexes, factories, hospitals.
Chilled water is circulated through air handlers.
Pros: Ideal for large-scale cooling.
Cons: Very complex and expensive.
Car / Truck AC
Compact system powered by the engine belt.
Includes compressor, condenser, evaporator, and expansion valve.
Bus / Van AC
Larger capacity, roof-mounted or rear-mounted units.
May use electric or engine-driven compressors.
