How to Choose the Right AC Tonnage
AC capacity (tonnage) is the most crucial factor for optimal cooling and energy efficiency. An undersized AC will struggle to cool your room, while an oversized one wastes electricity and creates uncomfortable humidity levels.
Room Size to AC Tonnage Chart
| Room Size | Recommended Tonnage | Ideal For | Power Usage |
|---|---|---|---|
| Up to 120 sq ft | 0.8 Ton | Small bedroom | 600W - 900W |
| 120 - 150 sq ft | 1.0 Ton | Medium bedroom | 800W - 1200W |
| 150 - 200 sq ft | 1.5 Ton | Large bedroom, small living room | 1000W - 1500W |
| 200 - 300 sq ft | 2.0 Ton | Living room, hall | 1200W - 1800W |
Insulation Factor
Poor insulation increases cooling requirements by 20-30%. Consider wall insulation, ceiling fans, and proper sealing for energy efficiency.
Sunlight Exposure
Rooms with direct sunlight need 10-15% higher capacity. West‑facing rooms in Indian climate require special consideration.
Room Occupancy
Add 0.1 ton for every 2 additional people regularly using the room. Each person generates approximately 400 BTU/hour of heat.
Split vs Window AC: Which is Better for Indian Homes?
The choice between split and window ACs significantly impacts your comfort, electricity bills, and home aesthetics. Here's a detailed comparison to help you make the right decision.
Split AC Benefits
Most popular choice for modern Indian homes with separate indoor and outdoor units.
Window AC Benefits
Single unit that fits in window or wall, budget‑friendly cooling solution.
💡 Recommendation for Indian Homes
Choose Split AC if: You prioritize quiet operation, aesthetics, and plan long‑term use. Ideal for bedrooms and living rooms where noise matters.
Choose Window AC if: Budget is primary concern, room has suitable window space, and occasional use. Good for guest rooms or temporary cooling needs.
Star Ratings & Power Savings: BEE Labels Explained
The Bureau of Energy Efficiency (BEE) star rating directly impacts your monthly electricity bills. Understanding these ratings helps you choose ACs that balance purchase cost with long‑term savings.
Understanding Star Ratings
Monthly Bill Impact (1.5 Ton AC)
Annual Savings: 5‑star vs 3‑star = ₹6,000
🎯 Smart Buying Advice
- 5‑star ACs pay for themselves within 2‑3 years through electricity savings
- Choose 4‑5 star for rooms used more than 6 hours daily
- 3‑star acceptable for occasional use guest rooms
Inverter vs Non‑Inverter Technology: Complete Analysis
Inverter technology is revolutionizing air conditioning in India. Understanding the difference helps you make cost‑effective decisions for long‑term comfort and savings.
How Technology Works
Inverter AC Technology
Variable speed compressor adjusts power based on room temperature requirements. Runs continuously at varying speeds, maintaining precise temperature control.
Non‑Inverter AC Technology
Fixed speed compressor turns on/off based on thermostat settings. Operates at full capacity when running, creating temperature fluctuations.
| Comparison Factor | Inverter AC | Non‑Inverter AC |
|---|---|---|
| Energy Efficiency | 30-50% more efficient | Standard efficiency |
| Purchase Price | ₹8,000‑15,000 higher | Lower initial investment |
| Monthly Electricity Cost | ₹800‑1,200 (1.5T) | ₹1,200‑1,800 (1.5T) |
| Noise Level | Ultra‑quiet operation | Noisier due to on/off cycles |
| Temperature Stability | Precise, consistent cooling | Temperature fluctuations |
| Expected Lifespan | 12‑15 years | 8‑12 years |
💡 Investment Analysis
Inverter ACs typically recover their higher cost within 2‑3 years through electricity savings. For a 1.5‑ton AC running 8 hours daily, annual savings range from ₹4,000‑8,000. Choose inverter for rooms used regularly; non‑inverter for occasional‑use areas.

Frequently Asked Questions
What AC tonnage do I need for a 200 sq ft room?
For a 200 sq ft room, 1.5 ton AC is typically ideal. However, consider ceiling height, insulation quality, sunlight exposure, and occupancy. Rooms with poor insulation or direct afternoon sunlight may need higher capacity.
Is inverter AC worth the extra investment?
Yes, inverter ACs typically pay for themselves within 2‑3 years through electricity savings. They consume 30‑50% less power, operate quietly, provide precise temperature control, and last longer. For regular use (6+ hours daily), inverter ACs are highly recommended.
Which AC brand offers best service in India?
LG, Voltas, and Blue Star have extensive service networks across India. Service quality varies by location, so always check service center availability and customer reviews in your specific area before buying.
What's the difference between 3‑star and 5‑star AC efficiency?
5‑star ACs consume 30‑40% less electricity than 3‑star models. While 5‑star ACs cost more initially, they save ₹4,000‑8,000 annually on electricity bills. The payback period is typically 2‑3 years, making them cost‑effective for regular use.
How often should I service my air conditioner?
Clean filters monthly during heavy use, service every 3‑4 months in peak season, and get an annual comprehensive service. In dusty areas or with pets, more frequent cleaning may be needed. Regular maintenance extends AC life and maintains efficiency.
What's the ideal temperature setting for energy savings?
Set your AC to 24‑26°C for optimal balance of comfort and efficiency. Each degree increase saves 6‑8% on electricity. Use ceiling fans to feel cooler at higher temperatures, and enable sleep mode during nighttime for additional savings.
Should I choose copper or aluminum coil AC?
