When summer hits hard and temperatures soar, an air conditioner (AC) becomes more of a necessity than a luxury. But buying an AC is a significant investment and not just about picking the most expensive model. There are several factors you need to consider to find the perfect fit for your needs.
In this comprehensive buying guide, we’ll walk you through everything you need to know before purchasing an air conditioner.
1. Understand the Types of Air Conditioners
The first step is understanding the different types of air conditioners available:
a. Window Air Conditioners
- Ideal for small to medium-sized rooms.
- Installed in a window frame.
- Affordable and easy to install.
- Can be noisy and may block the window.
b. Split Air Conditioners
- Consist of two units: indoor and outdoor.
- Suitable for larger rooms.
- Quieter than window units.
- More aesthetically pleasing.
c. Portable Air Conditioners
- Mobile units that can be moved from room to room.
- No permanent installation required.
- Less efficient and noisier than other types.
d. Inverter vs. Non-Inverter AC
- Inverter ACs adjust their compressor speed based on the temperature, saving more energy.
- Non-Inverter ACs operate at fixed speeds and consume more electricity.
2. Determine the Right Capacity
The cooling capacity of an AC is measured in tons. Choosing the right capacity ensures efficient cooling and saves electricity.
| Room Size (sq. ft.) | Recommended AC Capacity |
|---|---|
| Up to 120 | 1 Ton |
| 121 – 180 | 1.5 Ton |
| Above 180 | 2 Ton |
Other factors like ceiling height, number of windows, and insulation also impact the capacity required.
3. Energy Efficiency and Star Ratings
Air conditioners consume a significant amount of electricity. Choosing an energy-efficient model can drastically reduce your power bills.
BEE Star Ratings (India Example)
- ACs are rated from 1 to 5 stars by the Bureau of Energy Efficiency (BEE).
- A 5-star AC is the most efficient and consumes less electricity.
- Inverter ACs generally have better efficiency compared to non-inverter models.
Look for the ISEER (Indian Seasonal Energy Efficiency Ratio) for better insight into performance during different seasons.
4. Key Features to Look For
Today’s air conditioners offer more than just cooling. Here are some features to consider:
a. Air Filters
- Anti-bacterial and dust filters improve air quality.
- Important for households with allergy-prone members.
b. Auto Restart
- Automatically resumes operation after a power cut with the previous settings.
c. Sleep Mode
- Adjusts temperature automatically at night for better comfort and energy savings.
d. Dehumidifier
- Helps reduce humidity levels, especially useful during monsoon season.
e. Wi-Fi & Smart Controls
- Allows control through smartphone apps or voice assistants.
- Great for smart homes.
5. Noise Levels
The noise level of an AC can impact your comfort, especially during sleep. Split ACs are generally quieter compared to window or portable units.
Check the decibel (dB) rating in the specifications:
- Below 40 dB is considered quiet.
- Above 50 dB might be noticeable, especially at night.
6. Installation & Maintenance
Proper installation plays a critical role in the performance of your AC.
Installation Tips:
- Ensure the outdoor unit (for split ACs) is installed in a shaded and ventilated area.
- Avoid long connecting pipes between the indoor and outdoor units for better efficiency.
- Hire authorized service technicians for installation.
Maintenance:
- Regular servicing keeps the AC running efficiently.
- Clean filters every 2–4 weeks.
- Schedule professional maintenance annually.
7. Brand Reliability and After-Sales Service
Choose a trusted brand with good customer reviews and a wide service network. Some reliable global and regional AC brands include:
- Daikin
- LG
- Mitsubishi Electric
- Panasonic
- Samsung
- Voltas
- Blue Star
- Hitachi
- Whirlpool
Check for:
- Warranty period (usually 1 year on the product, 5–10 years on the compressor).
- AMC (Annual Maintenance Contracts) for hassle-free service.
8. Budget Considerations
Price varies based on capacity, features, and brand.
Average Price Range (Indicative):
- 1 Ton Window AC: $250 – $400
- 1 Ton Split AC (Non-Inverter): $350 – $600
- 1 Ton Split AC (Inverter): $500 – $800
- 1.5 Ton Split AC (Inverter): $700 – $1,200
Keep an eye out for seasonal discounts, especially during summer and festive sales.
9. Environmental Impact
Eco-friendliness is becoming a key factor for many buyers.
Look for:
- Refrigerant Type: Choose ACs with R32 or R410A refrigerants, which are more eco-friendly and efficient than older gases like R22.
- Energy Star Certification: Indicates better environmental performance.
10. Final Checklist Before Buying
Here’s a quick checklist to help you finalize your purchase:
- ✅ Right type (Window/Split/Portable)
- ✅ Suitable capacity (in tons)
- ✅ High energy rating (preferably 4–5 stars)
- ✅ Necessary features (sleep mode, filters, Wi-Fi, etc.)
- ✅ Quiet operation
- ✅ Reliable brand with good service support
- ✅ Fair price and good warranty terms
- ✅ Environmentally friendly refrigerant
Conclusion
Buying the right air conditioner doesn’t have to be overwhelming. Start by identifying your room size, usage needs, and budget. Pay attention to efficiency, features, and service options. A good AC not only keeps you cool but also saves energy and lasts longer.
Always read reviews, compare models, and ask for expert advice if needed. A well-informed decision today ensures years of comfort ahead.
Samsung Demo Phone
The Samsung Demo Phone currently tops our rank of the greatest Samsung phones available, beating even the pricier iPhone Ultra Max Mega.
So unsurprisingly this is an absolutely fantastic phone. The design isn't massively changed from the previous generation, but most other elements have been upgraded. This is what we call a big boost.
