Air Conditioning Guide: Tips, Types, and Energy Efficiency
An air conditioner (AC) is an electrical appliance designed to cool indoor air, control humidity, and improve comfort in warm or hot weather. It works by removing heat from inside a room and releasing it outside, making your living or working space cooler and more pleasant.
As temperatures continue to rise in Nepal, air conditioners (ACs) are no longer a luxury they have become a necessity for homes, offices, shops, and commercial spaces. If you’re planning to buy an AC, understanding the air conditioner cost in Nepal, available types, and key buying factors will help you make the right decision.
Summary and Cost of Air Conditioner in Nepal
Detailed Overview

It focuses on high ambient cooling, low voltage operation, and quiet performance important features in Nepal’s varied electricity conditions. It includes basic comfort features like active dehumidifier and antimicrobial filtering. The TATA Vertis 1 Ton Air Conditioner is a non-inverter split AC model designed for comfortable year-round temperature control in residential spaces. It packs standard cooling and key convenience features into a budget-friendly package, making it suitable for bedrooms, living rooms, or offices around 120 sq ft to 150 sq ft under typical conditions.
Chigo 1 Ton Inverter Split AC CS-35V3G-NP
The Chigo 1 Ton Inverter Split AC CS-35V3G-NP is a wall-mounted inverter split air conditioner optimized for medium-sized rooms (120–170 sq ft). Inverter technology adjusts compressor speed for energy-efficient cooling and heating, making it a good choice for everyday home use. This model uses R32 refrigerant, works across a wide temperature range, and includes smart features like auto-restart and defrost functions.
Chigo 1.5 Ton Inverter CS-51H3A-1B170
The Chigo CS‑51H3A‑1B170 is a 1.5 Ton wall‑mounted split air conditioner designed for medium to large rooms (up to 60 m² or 650 sq ft). It offers powerful cooling and heating performance with reliable comfort throughout the year. This model provides fast and uniform cooling thanks to robust airflow and a standard rotary compressor. It uses an eco‑friendly refrigerant (typically R410A) and comes with essential features such as auto‑restart and remote controls for easy use. The indoor unit operates at a moderate noise level suitable for bedrooms and living areas.
Chigo 2 Ton Inverter CS-70V3G
The Chigo 2 Ton Inverter Split AC CS-70V3G is ideal for large rooms or open living spaces. It uses advanced inverter technology and eco-friendly R32 refrigerant to deliver powerful cooling with better electricity efficiency. Smart features include self-diagnosis, auto-restart, and timer settings. consistent cooling for medium-sized rooms, typically around 250–350 ft² (23–33 m²). While this AC is perfect for medium-sized rooms, smaller rooms may benefit more from a 1.5-ton unit for optimal efficiency. Proper installation and room insulation further enhance performance, making the Chigo CS‑70V3G a reliable choice for consistent, efficient cooling.
Chigo 3 Ton Cassette CCA-36HR1-A
The Chigo 3 Ton CCA-36HR1-A Ceiling Cassette AC is designed for commercial spaces, large halls, offices, and open areas. Unlike wall-mount splits, it installs in the ceiling for wide and even air distribution. It uses R410A refrigerant and requires three-phase power. For a medium-sized room in Nepal (about 120–170 sq ft / 11–16 m²), the Chigo 2 Ton Inverter CS-70V3G is generally larger than needed. A 2 Ton AC is better suited for larger living rooms or open spaces.
How Does an Air Conditioner Work?
-
Evaporation: Refrigerant absorbs heat from indoor air at the evaporator coil and changes from liquid to gas.
-
Compression: The gaseous refrigerant is compressed, increasing its pressure and temperature.
-
Condensation: Heat is released outside at the condenser coil, and the refrigerant turns back into liquid.
-
Expansion: The liquid refrigerant passes through an expansion valve, cools down, and the cycle repeats.
Energy Efficiency Tips
To make your AC more efficient and save money:
-
Set temperature around 24–26 °C
-
Use ceiling or pedestal fans along with AC
-
Clean filters regularly
-
Keep doors and windows closed
-
Use timer mode when you’re asleep or away
-
Shade outdoor unit from direct sun
Choosing the Right AC Based on Your Needs
-
Bedrooms / Small Rooms: 1 Ton split AC (ideally inverter)
-
Living Rooms / Larger Spaces: 1.5-2 Ton inverter split AC
-
Offices / Halls: Cassette or multi-split systems
-
Budget-Friendly Option: Window or basic split AC
Types of Air Conditioners
1. Window AC
-
Compact unit installed on a window or wall opening.
-
All components are in one box.
-
Best for small rooms.
-
Usually more affordable but louder.
2. Split AC
-
Two units: Indoor unit (evaporator + controls) and Outdoor unit (compressor + heat exchanger).
-
Quieter operation and better cooling distribution.
-
Available in inverter and non‑inverter types.
3. Inverter AC
-
Uses variable‑speed compressor technology.
-
Adjusts power based on cooling need.
-
More energy efficient and quieter, especially with frequent on/off cycles.
4. Cassette AC
-
Mounted in the ceiling.
-
Ideal for large rooms or commercial spaces.
-
Even 360° air distribution.
5. Portable & Floor Standing AC
-
Movable units (less common in Nepal).
-
Good for temporary cooling without permanent installation.
Conclusion:
Choosing the right air conditioner ensures better cooling, energy savings, and long-term comfort. Select the AC capacity based on room size and prefer inverter models for efficient everyday use. The right choice delivers reliable performance while keeping electricity costs under control.
Air conditioner prices in Nepal usually start from around NPR 50,000 for basic 1 Ton split AC models and can go above NPR 150,000 for commercial cassette AC units. Prices depend on brand, capacity, inverter technology, and features. Inverter ACs cost more initially but save electricity in the long run.
For Nepal’s hot summers and unstable voltage conditions, inverter split ACs are the best choice. They handle temperature fluctuations better, consume less electricity, and work efficiently during long usage hours. Brands like Chigo and TATA offer models designed for high ambient temperatures common in Nepal.
Room size is the key factor when choosing AC capacity in Nepal. A 1 Ton AC is suitable for bedrooms up to 150 sq ft, 1.5 Ton works well for living rooms, and 2 Ton ACs are ideal for large spaces. Oversized or undersized units increase electricity bills.
Yes, inverter ACs are highly energy efficient in Nepal, especially where electricity costs are rising. They adjust compressor speed based on cooling demand, reducing power consumption. In homes where ACs run for long hours, inverter ACs can reduce electricity bills significantly compared to non inverter models.
Popular AC brands in Nepal include Chigo, TATA, LG, Samsung, and Gree. Chigo and TATA are widely chosen for their competitive prices, availability of spare parts, and compatibility with Nepal’s power conditions. Choosing an authorized seller ensures better warranty and after sales service.
