🌬️ Introduction
Buying a new air conditioner is an investment in your comfort, especially during the scorching Indian summers. But with so many models, features, and brands on the market, how do you choose the right one?
At ChillZone, we’ve created this complete AC Buying Guide 2025 to help you make an informed decision—whether you’re buying your first AC or upgrading an old one.
🛒 Top 10 Things to Look for When Buying an AC
✅ 1. Room Size and AC Capacity
Start with the basics: How big is the room you’re cooling?
| Room Size (sq. ft.) | AC Tonnage Required |
|---|---|
| Up to 100 sq. ft. | 0.75 Ton |
| 100 – 150 sq. ft. | 1 Ton |
| 150 – 250 sq. ft. | 1.5 Ton |
| 250 – 400 sq. ft. | 2 Ton |
Getting the right size ensures efficient cooling and lower electricity bills.
✅ 2. Energy Efficiency (Star Ratings)
Look for the BEE star rating on the AC. More stars = more energy savings.
A 5-star inverter AC may cost more initially but saves a lot over time.
➡ Pro Tip: Check the ISEER rating for more accurate energy performance.
✅ 3. Inverter vs Non-Inverter Technology
- Inverter AC: Adjusts power based on cooling needs. Saves electricity and runs quietly.
- Non-Inverter AC: Cheaper but less energy efficient and noisier.
Choose inverter AC if you use it for long hours daily.
✅ 4. Type of AC: Split or Window
- Split AC: Better aesthetics, silent operation, suitable for medium to large rooms.
- Window AC: Budget-friendly, easy to install, ideal for smaller spaces.

✅ 5. Air Filters and Air Quality Features
Go for ACs with PM 2.5 filters, anti-bacterial filters, and dehumidifiers—especially if you live in a dusty or humid area.
✅ 6. Smart Features
Modern ACs come with:
- Wi-Fi control
- Voice assistant compatibility (Alexa/Google)
- Mobile apps for scheduling & temperature control
➡ Ideal for tech-savvy homes and remote control convenience.
✅ 7. Cooling Modes and Convenience
Look for features like:
- Sleep Mode
- Turbo Mode
- Eco Mode
- Auto Restart
These options improve user comfort and energy savings.
✅ 8. Noise Level
If you’re buying for a bedroom or study room, choose an AC with low indoor noise (below 40 dB is ideal).
✅ 9. Build Quality & Durability
Consider brands with:
- Copper condenser coils (better than aluminum)
- Anti-corrosive coatings (for coastal regions)
➡ These extend the lifespan and performance of the AC.
✅ 10. Warranty and After-Sales Service
Always check:
- Warranty on compressor (usually 5–10 years)
- On-site service availability
- Access to authorized service centers
At ChillZone, we ensure only trusted brands with reliable service support.
🛍️ Bonus: Budget Considerations
Make sure to compare initial cost + electricity usage. Sometimes spending a little more on an efficient inverter AC saves you more in the long run.
