A Complete AC Buying Guide
India’s diverse climate zones and rising temperatures make air conditioning essential for comfort in most regions. With average summer temperatures exceeding 40°C in many cities and humidity levels soaring in coastal areas, choosing the right air conditioner is crucial for home comfort, energy efficiency, and long-term savings. This comprehensive guide covers everything you need to know to make an informed purchase decision.
1. Types of Air Conditioners
Split Air Conditioners
Split ACs are the most popular choice for Indian homes, consisting of an indoor unit and outdoor compressor.
Advantages:
- Quieter operation with the compressor placed outside

Disadvantages:
- Higher initial cost (₹25,000-₹80,000)
- Requires professional installation
- More complex maintenance
Window Air Conditioners
Traditional single-unit ACs installed in window openings or wall cutouts.
Advantages:
- Lower cost (₹18,000-₹35,000)
- Easier installation and maintenance
- No external piping required
Disadvantages:
- Noisy operation
- Blocks window space and natural light
- Less energy efficient
- Limited inverter options
Portable Air Conditioners
Mobile units suitable for renters or temporary cooling needs.
Advantages:
- No permanent installation required
- Can be moved between rooms
- Ideal for rented apartments
Disadvantages:
- Lower cooling efficiency
- Higher operating costs
- Limited cooling capacity
- Requires exhaust hose placement
2. Essential Features to Consider
Inverter vs Non-Inverter Technology
Inverter Technology: Adjusts compressor speed continuously based on temperature requirements, leading to 30-50% energy savings. Initially costs ₹5,000-₹10,000 more but recovers the difference through lower electricity bills within 2-3 years. Ideal for daily use and regions with extended summers.
Non-Inverter Technology: Operates at fixed speed, cycling on and off. Lower upfront cost but higher electricity consumption. Suitable for occasional use or budget-conscious buyers with limited AC usage.
Star Rating and Energy Efficiency
The Bureau of Energy Efficiency (BEE) star rating indicates energy efficiency on a scale of 1 to 5 stars, with 5 stars being most efficient. As of 2026, new ISEER (Indian Seasonal Energy Efficiency Ratio) ratings provide more accurate year-round efficiency measurements.
Annual Electricity Cost Comparison (1.5 Ton AC, 8 hours daily):
| Star Rating | ISEER | Units/Year | Annual Cost |
| 3 Star | 3.5 | 1,050 | ₹7,350 |
| 4 Star | 4.0 | 920 | ₹6,440 |
| 5 Star | 4.5+ | 820 | ₹5,740 |
Note: Based on ₹7 per unit electricity cost
Tonnage Calculation
Tonnage determines cooling capacity. The right size depends on room area, ceiling height, sun exposure, number of occupants, and heat-generating appliances.
| Room Size (sq ft) | Recommended Tonnage | Typical Room Type |
| Up to 110 | 0.8 Ton | Small bedroom |
| 110-150 | 1.0 Ton | Medium bedroom |
| 150-200 | 1.5 Ton | Large bedroom, living room |
| 200-300 | 2.0 Ton | Large hall, office |
Adjustment Factors:
- Top floor or west-facing rooms: Add 0.5 ton
- More than 3 occupants: Add 0.5 ton
- Kitchen or heat-generating equipment: Add 0.5 ton
- Well-insulated room with minimal sun exposure: Reduce by 0.25 ton
Advanced Features
Copper vs Aluminum Coils: Copper coils offer better heat transfer, durability, and easier repairs. Aluminum coils are lighter and cheaper but less efficient and harder to repair.
Dual Inverter Technology: Uses dual rotary compressors for faster cooling, quieter operation, and 40% more energy savings compared to conventional inverter ACs.
Air Purification: PM 2.5 filters, ionizers, and anti-bacterial coatings help remove pollutants, allergens, and bacteria from indoor air—essential in polluted Indian cities.
Wi-Fi Connectivity: Smart ACs allow remote control via smartphone apps, voice commands through Alexa/Google Assistant, and scheduling for energy optimization.
Stabilizer-Free Operation: Built-in voltage stabilizers protect against power fluctuations (130-290V range), crucial in areas with unstable electricity supply.
Turbo/Jet Mode: Provides instant cooling at maximum capacity, useful for quickly cooling rooms during peak summer hours.
Sleep Mode: Automatically adjusts temperature during night hours, maintaining comfort while saving energy.
