Let’s understand the differences in a bit more detail.

Cooling Capacity

The cooling capacity of an AC measures the power of AC. It means that more powerful AC will have a higher cooling capacity.

In India, it is measured in tons or watts per hour. In several countries, it is also measured in BTUs (British Thermal Units).

For example, 1.5 ton AC’s cooling capacity is 5275 watts per hour. It is nothing but the output wattage.

However, different brands have different cooling capacity as per their tonnage.

  • Cooling capacity of 1.5 ton Daikin AC = 5000 watts
  • Cooling capacity of 1.5 ton Hitachi AC = 5275 watts

As you can see, Hitachi AC has around 5.5% more cooling capacity as compared to Daikin AC.

Energy Consumption

Energy consumption of ACs depends on capacity (tonnage) and ISEER rating. If you have started searching for ACs, then you must have come across this terms ISEER. This rating measures the energy efficiency of ACs. It means that a higher ISEER rating will result in lower power consumption.

Both Hitachi and Daikin offer energy-efficient ACs. 5-star ACs are the most power-efficient ACs that consume lowest power in their category. We did a comparison of Hitachi and Daikin’s ISEER rating and found out interesting numbers.

  • Most 5-star Daikin ACs have ISEER of 4.7 to 5.2.
  • Most 5-star Hitachi ACs have an ISEER of 4.55 to 4.7

On top of this, as discussed earlier, Daikin ACs come with lower wattage as compared to Hitachi. Hence, premium Daikin ACs are more power-efficient than Hitachi ACs.

The formula for power consumption is

Energy Consumption = Cooling capacity / ISEER

Daikin AC energy Consumption with 4.7 ISEER = 5000 / 4.7 = 1064 watts per hour

This is equal to 1.06 units

Hitachi AC energy Consumption with 4.55 ISEER = 5275 / 4.55 = 1160 watts per hour

This is equal to 1.16 units

Hence it is safe to say that a 5-star Hitachi AC consumes around 9 percent more power than a 5-star Daikin AC. This difference is quite big when you are planning to use AC for longer duration.

Variety

Hitachi’s offering is quite limited when it comes to the Indian market. First of all, Hitachi only offers ACs for residential customers. It means that it only offers split and window ACs. On top of this, the variety and types of ACs is these segments are quite limited.

This is not good for you if you want to purchase an AC as per your preferences.

On the other hand, Daikin offers ACs for residential as well as commercial customers. Moreover, the variety it offers in split and window AC category is huge. Earlier Daikin did not offer window ACs, but off late it has started offering good quality window ACs in India.

Noise Level

Noise level of ACs is measured in decibels or dB. Even though both the brands offer ACs that produce less noise, some Daikin ACs come with better noise specifications than Hitachi.

While most Hitachi and Daikin ACs produce around 35 dB noise, some Daikin ACs in India come with less than 30 dB noise levels.

Refrigerant Used

As discussed, Daikin is the pioneer of R32 refrigerant since it was the inventor of this refrigerant. Now almost every AC that Daikin offers comes with this refrigerant. R32 is better than R410A refrigerant in terms of cooling (only slightly better) and in terms of eco-friendliness. Also, R32 is more modern refrigerant. This means that chances of this refrigerant going obsolete in near future are low.

Hence, if you buy a Daikin AC, you need not worry about repair/maintenance in future and you will be contributing to the environment as well.

On the other hand, Hitachi offers ACs with R32 as well as R410A refrigerant. There is no significant advantage of R410A over R32. However, R410A refrigerant will phase out in the next few decades considering its planned phase-out in the US in the year 2024.

However, it gives more choice to you in terms of which refrigerant might be your preferred choice.

Hence, there is no clear winner here.

After Sales Service

Even though Daikin, as well as Hitachi both, offer decent customer service, Hitachi’s after-sales service is better than Daikin in general.

Price

Daikin offers some of the most affordable ACs in India. On the other hand, finding a cost-effective AC from Hitachi can be a little difficult.

Warranty

Warranty periods of Daikin and Hitachi are quite similar. The usual warranty period is 1 year on product and 5 years on motor.

Daikin vs Hitachi: Split AC

We have chosen the best split ACs from both brands for your convenience.
