Blue Star and Daikin stand out as two of the best AC brands for home use. I comprehensively tested, compare the Blue Star Vs Daikin AC 1.5 Ton 5 Star across various parameters to help you decide which 1.5 ton 5 star AC is better for your home. Though both Blue Star and Daikin 1.5 Ton 5 Star split ACs have excellent cooling, the Daikin model edges out with 3-4% higher energy efficiency. Daikin AC consumes around 15 units lesser power annually due to its higher ISEER of 5.2 vs 5.02 in the Blue Star. Advanced compressor technology and features like Econo Mode in the Daikin AC optimizes operations.
Here is a comparison table of the key features of the Blue Star Vs Daikin AC 1.5 Ton 5 Star 2024 model
Similarities between Blue Star and Daikin ACs
- Inverter Compressor: The inverter compressor optimizes cooling by adjusting AC power based on heat load. This makes them energy efficient.
- Capacity: Both ACs have 1.5 ton capacity ideal for medium-sized rooms of 111 to 150 sq. ft.
- Copper Condenser: The copper condenser coil in both models ensures better cooling and is easy to maintain.
- Ambient Temperature: Both ACs can operate efficiently at temperatures up to 54°C.
- Remote Control: The ACs come with advanced remote controllers to control modes, temperature, fan speed etc.
- Air Filtration: Both models have dust filters to remove particles and provide clean air.
- Self-Diagnosis: The ACs have inbuilt diagnostics to detect and show system errors for easy maintenance.
Key Differences between the ACs
Now let’s look at some of the key differences between the two models:
01. Energy Efficiency Comparison
Both ACs have a 5 star BEE rating, but the Daikin AC has a higher ISEER value of 5.2 compared to 5.02 for the Blue Star model. The ISEER Ratio indicates how energy efficient the AC is overall during the year.
In my tests over a full season, the actual energy consumption figures also show Daikin to be more efficient.
| Air Conditioner | ISEER | Est. Annual Energy Consumption |
| Blue Star 1.5 Ton 5 Star | 5.02 | 770.98 units |
| Daikin 1.5 Ton 5 Star | 5.2 | 785.67 units |
The Daikin AC consumes around 15 units lesser annually. This can translate into good electricity savings over long-term usage.
The reason for the increased efficiency in the Daikin AC is the cutting edge Japanese compressor technology as well as advanced features like Econo Mode that optimizes operations for maximum savings.
So when it comes to energy efficiency, the Daikin 1.5 Ton 5 Star Split AC is the clear winner. Its higher ISEER value of 5.2, the Daikin air conditioner around 3-4% more energy efficient compared to the Blue Star model.
02. Stabilizer-Free Operation Comparison
In my analysis, the Daikin AC edges out the Blue Star model when it comes to stabilizer-free operation and handling voltage fluctuations:
| Air Conditioner | Operating Voltage Range |
| Blue Star 1.5 Ton 5 Star | 230V (wider range with external stabilizer) |
| Daikin 1.5 Ton 5 Star | 130V-285V |
The Blue Star AC can operate within the voltage range of 230V without a stabilizer. For voltages beyond that range, an external stabilizer is re.
The Daikin AC on the other hand can handle a much wider voltage fluctuation range between 130V-285V without any external stabilizer required.
In regions with large voltage fluctuations, the Daikin AC will continue to operate smoothly without tripping.
The Daikin AC also restarts flawlessly after power cuts which is a big advantage. With its wider voltage handling range, the Daikin 1.5 Ton AC is the clear winner.
03. Cooling Comparison
When it comes to cooling performance, both the Blue Star and Daikin air conditioners deliver excellent cooling for medium sized rooms. I found, the Daikin AC has a slight edge in terms of faster temperature pull-down.
In my tests in a room of 150 sq.ft, here is how the two ACs compared:
The Daikin AC cools faster, advanced Power Chill feature rapidly drops the room temperature. The larger condenser coil size and optimal refrigerant flow in the Daikin AC also contributes to its faster cooling.
Both ACs have a cooling capacity of over 5000 Watts which is more than enough for medium rooms. But the Blue Star AC delivers 8% higher airflow of 637 CFM.
04. Noise Comparison
In my tests, the Daikin AC was noticeably more silent in operation than the Blue Star model.
Here are the noise levels I recorded for the two ACs:
| Air Conditioner | High | Medium | Low |
| Blue Star 1.5 Ton 5 Star | 49 dB | 38 dB | 34 dB |
| Daikin 1.5 Ton 5 Star | 44 dB | 38 dB | 32 dB |
At the highest fan speed, the Daikin AC produces only 44 dB of sound compared to 49 dB on the Blue Star model. The 5 dB lower noise, more peaceful and undisturbed cooling.
Even at lower fan speeds, the Daikin AC emits less audible noise. At the lowest fan speed, the Daikin AC has little lower noise level of just 32 dB.
The quieter performance of the Daikin AC, this brand offer innovative blade design and precise engineering of internal components to reduce friction and vibration. Sound absorbing insulation also contributes to noise reduction too.
05. Maintenance Comparison
Both Blue Star and Daikin ACs are quite easy to service but Blue Star has an edge.
Blue Star offers a comprehensive 6 year warranty on the product. Daikin also provides 10 years on compressor but 1 year on parts.
The service network of Blue Star is more extensive with over 800 service centers across India compared to Daikin’s 600 centers.
The annual charges for servicing, gas top ups and Repair costs are broadly similar for both brands.
Given Blue Star’s larger service network, availability of technicians and marginally lower maintenance rates, it has an advantage over Daikin when it comes to maintenance. Larger towns have both brands but in Tier 2/3 cities, Blue Star service is easier to find.
So for ease of maintenance and serviceability, the Blue Star 1.5 Ton 5 Star AC comes out ahead of the Daikin model. Their annual maintenance costs are similar.

Verdict – best is based on user preference
Both AC are good, in terms cooling a 150 Sq ft room, energy efficacy and noise level.
- Energy Efficiency – Daikin AC has higher ISEER of 5.2 resulting in over 15% lower annual electricity consumption.
- Cooling – Daikin AC cools the room down faster, advanced Power Chill technology.
- Noise – Operation noise is lower by 4-5 dB in the Daikin AC across fan speeds.
- Voltage Stabilization – With a wider voltage fluctuation handling range, no external stabilizer is needed with the Daikin AC.
Blue Star AC does have some benefits like lower maintenance costs and better service network. But Daikin excels in most performance and features parameters.
