As summer temperatures continue to rise in India, investing in a reliable and energy-efficient air conditioner becomes essential. While split ACs are widely popular, window ACs remain a preferred choice for their affordability, compact design, and easy installation. The Window Air Conditioner is the air conditioning system that is mounted on windows or walls. It cools down the air of the room, removes heat, and controls the humidity. In some cases, it also purifies the air. A 1.5-ton window AC is ideal for rooms sized between 120 to 180 sq. ft. However, choosing the right window AC requires considering cooling performance, energy efficiency, durability, and advanced features. A 5-star rated window AC ensures lower power consumption, which translates into significant savings on electricity bills over time. In this guide, we have carefully researched, compared, and reviewed the best 1.5-ton 5-star window ACs available in India in 2025.
Factors you should consider before buying a window AC:
Buying a 1.5-ton window AC isn’t just about picking the most expensive or popular model. You need to make sure it’s the right fit for your space, energy-efficient, durable, and packed with the right features. Here are some key factors to consider before making your purchase:
1. Tonnage – Choosing the Right Capacity
The tonnage of an AC refers to its cooling capacity and determines how effectively it can cool a room. It is measured by the amount of heat required to melt ice in 24 hours.
1 Ton AC → Suitable for small rooms (up to 130 sq. ft.)
1.5 Ton AC → Ideal for medium-sized rooms (130-180 sq. ft.)
If your room is bigger than 180 sq. ft., or has multiple windows and direct sunlight exposure, you might need a higher-capacity AC or an additional cooling solution.
2. Energy Rating – Save More on Electricity Bills
The energy rating of an AC determines how efficiently it uses electricity. A higher BEE (Bureau of Energy Efficiency) Star rating means better efficiency and lower electricity bills.
5-Star AC → Best energy efficiency, higher upfront cost but long-term savings.
3-Star AC → Decent energy savings, more affordable initially but consumes more power over time.
If you plan to use the AC for long hours daily, investing in a 5-star AC is the best choice, as it reduces power consumption significantly.
3. Compressor Type – Inverter vs Non-Inverter ACs
Inverter Compressor ACs: Adjust cooling speed based on room temperature, offering better efficiency, less noise, and lower power consumption.
Non-Inverter ACs: Operate at a fixed speed, meaning they consume more power and cycle on and off frequently, leading to higher energy bills.
If budget is not a major concern, always go for an inverter window AC for long-term benefits.
4. Condenser Coil – Copper vs Aluminum
The condenser coil plays a crucial role in heat exchange and cooling efficiency. You’ll generally find two types of coils:
Copper Condenser Coil – Better heat transfer, more durable, and requires low maintenance.
Aluminum Condenser Coil – Cheaper, less efficient, and prone to corrosion over time.
Always choose a copper condenser coil for better performance and longevity.
5. Air Filters – Ensuring Cleaner Air
A good air conditioner should not just cool the room but also improve indoor air quality. Air filters help trap dust, pollen, smoke, and odors, ensuring fresh, clean air circulation. Look for ACs with:
High-Density Filters – Remove fine dust particles and allergens.
Anti-Bacterial Filters – Prevent mold and bacteria growth inside the AC.
For cities with high pollution levels, air filters are a must-have feature.
6. Dehumidifier – A Must-Have for Humid Areas
During monsoons, excessive humidity can make rooms feel stuffy and uncomfortable. A built-in dehumidifier helps maintain optimal humidity levels by reducing excess moisture in the air, making the environment cooler and more comfortable.
If you live in coastal areas or cities with high humidity, ensure your AC has this feature.
7. Blower Fan – Stronger Air Circulation
The blower fan in an AC ensures even airflow distribution across the room. The bigger the fan, the better the cooling experience. If you want strong airflow, look for an AC with a powerful blower fan and multiple speed settings.
8. Additional Smart Features to Look For
Apart from the basics, several advanced features enhance convenience and efficiency:
- Turbo Cooling Mode – Ensures rapid cooling during extreme heat.
- Sleep Mode – Gradually increases the temperature at night for better comfort.
- Auto Restart – Saves previous settings and resumes operation after a power cut.
- Energy Saver Mode – Optimizes power consumption while maintaining cooling.
- Remote Control with Night Glow Buttons – Makes it easier to operate in the dark.
