In the sweltering Indian summers, an air conditioner is no longer a luxury but a necessity. With rising temperatures every year, having an energy-efficient AC has become crucial – both for your comfort and to reduce your electricity bills.
Choosing the right air conditioner can be confusing with the numerous technical specifications, different types of ACs, and a range of energy ratings to consider. This article will discuss the latest energy-efficient AC models in 2024 and provide all the information you need to pick the best one for your home.
We will cover the different types of energy-saving air conditioners, compare top AC brands and models along with their specifications, pros and cons.
Types of Energy-Efficient Air Conditioners
Here are the most energy-efficient types of air conditioners available in India:
1. Inverter ACs
Inverter or variable-speed ACs adjust their cooling capacity based on heat load. This results in steady comfortable temperature, quicker cooling and massive energy savings of up to 60% compared to fixed speed ACs.
2. 5 Star Rated ACs
Air conditioners with higher BEE star ratings, especially 5-star models, are designed to be more energy efficient. They consume less electricity and are cost-effective in the long run.
3. Copper Condenser Coil ACs
Copper coil condensers enhance heat transfer efficiency, resulting in faster cooling with lower electricity usage. They are also more durable than aluminium coils.
4. Smart ACs
Smart air conditioners can be controlled remotely via WiFi using your smartphone. This allows you to optimise AC usage and set schedules to maximise energy savings.
5. Window ACs with Shade Control
Special sensors in the AC detect sunlight and adjust cooling to save power. Window ACs also need lesser maintenance compared to split ACs.
6. Precision Cooling ACs
These ACs allow you to precisely control the temperature between adjacent rooms and closely maintain preset temperatures. This reduces wasteful overcooling.

Split vs Window Air Conditioner – Which is More Energy-efficient?
When it comes to energy efficiency, there is not much difference between split and window ACs if both models have the same BEE star rating and capacity.
However, the following factors make split ACs slightly more energy-efficient:
| Factors | Split AC | Window AC |
| Inverter Compressor | Most have advanced inverter compressors | Typically use fixed-speed compressors and also come with inverter technology |
| Customised Cooling | Allows directed airflow for efficient cooling | Limited airflow direction, potential for overcooling |
| Air Tightness | Mounted away from windows for better sealing | Directly installed in windows, may lead to air leakage |
| Maintenance | Easier to service regularly | Filters harder to clean, more dust accumulation |
| Energy Efficiency | Slightly more efficient due to above factors | Comparable if both have same BEE star rating and capacity |
| Installation Cost | Generally higher | Lower |
| Room Size | Suitable for larger rooms | Suitable for smaller rooms |
| Usage | Depending on usage and room layout | Depending on usage and room layout |
| Budget | Higher initial investment | Lower initial investment |
However, for a small room, a 5-star rated window AC can be equally or even more energy saving than a split AC. Also, window ACs require lower installation costs.
So consider your room size, usage and budget when deciding between the two.

Frequently Asked Questions
1. How to calculate energy consumption of AC?
An AC’s energy rating is measured in Watts. To calculate hourly energy consumption – Multiply AC capacity (in Tons) x 12,000 x Hours used. For example, a 1.5 Ton AC used for 8 hours will consume 1.5 x 12,000 x 8 = 144 kWh. Monthly consumption depends on usage hours.
2. Which AC is more energy efficient: Window or Split?
If both ACs are rated equally, split ACs are slightly more efficient due to inverter compressor, better air tightness and easier maintenance. However, 5-star window ACs can be equally or more efficient for small rooms.
3. What is the most energy-saving temperature for an Air Conditioner?
Keeping the AC thermostat between 24-27°C provides maximum energy savings. This is the most comfortable range for people without overcooling the room. Setting lower temperatures increases electricity consumption exponentially.
