Daikin and Hitachi are two of the most trusted air conditioner brands from Japan. But while both offer high cooling performance, their technologies showcase some key variances. Daikin emphasizes noise reduction and energy savings, with models rated up to 15% more efficient than Hitachi. Hitachi focuses more on wide area cooling, with capacities to effectively maintain temperature in spaces up to 30% larger than comparable Daikin units. So which is better for your needs? Let’s find out
Daikin vs. Hitachi 1.5 Ton AC’s
Regarding cooling capacity, energy efficiency, noise levels, and features, Daikin and Hitachi 1.5-ton air conditioners have notable differences.
Looking at comparable 5 star inverter split AC models, the Daikin 1.5 ton AC provides a higher ISEER rating of 5.2 versus 5.02 for the Hitachi unit. This results in greater annual energy savings – the Daikin consumes 813 units yearly while the Hitachi uses 1012 units for the same cooling output.
Regarding maximum cooling capacity, the Daikin offers 5280 Watts compared to 5275 for the Hitachi. For a medium room of 120 sq.ft, both can effectively maintain the desired temperature.
The Daikin is quieter at the lowest fan setting for noise levels with just 32 dB versus 34 dB for Hitachi. However, at higher speeds they are closer at 48 dB and 46 dB respectively. Those sensitive to noise should consider the Daikin.
The Daikin’s PM 2.5 filter also provides superior air purification over the Hitachi’s dust filter. It removes fine particles up to 2.5 microns for cleaner indoor air quality.
Both brands include useful features like stabilizers, dew clean technology, and turbo modes. The Hitachi does have wider horizontal swing louvres for improved air distribution.
When looking at 3 star models, the differences are less pronounced. The Hitachi again edges out on capacity at 5000 Watts over the Daikin’s 5000. Noise levels and air filters are comparable.
Daikin is preferable for the highest efficiency and air purification, while the Hitachi offers wider airflow coverage and slightly better cooling capacity.
Daikin vs. Hitachi 1 Ton AC’s
For small rooms up to 120 sq.ft, Daikin and Hitachi both offer capable 1 ton ACs but have some variances in efficiency, capacity, and noise.
Looking at 5 star inverter models, the Daikin AC has a higher ISEER of 5.2 compared to 5.02 for the Hitachi. So the Daikin provides greater energy savings annually – around 680 units less than the Hitachi per year.
In terms of maximum cooling capacity, the Daikin offers 3520 Watts while the Hitachi provides 3458 Watts. Both can effectively maintain desired temperature in a small room.
For noise levels, the Daikin is quieter at the lowest fan speed at 27 dB versus the Hitachi at 32 dB. At the highest speed, they are closer at 42 dB for Daikin and 42 dB for Hitachi. For those who want whisper quiet operation, the Daikin is preferable.
The Daikin also includes superior PM 2.5 filtration to remove fine particles from the air compared to the Hitachi’s dust filter.
Both models include useful features like stabilizers, timers, dew prevention, and turbo cooling modes. Daikin offers a wider temperature set range of 16-30°C over Hitachi’s 18-30°C.
Comparing 3 star units, the differences are less significant. Hitachi rates slightly higher in capacity at 3458 Watts versus 3500 for Daikin. Their noise levels and filters are similar.
If you want maximum efficiency and air purification should choose the Daikin 1 ton AC, while the Hitachi is a bit more powerful for the price.
Daikin vs. Hitachi 2 Ton AC’s
When cooling larger spaces of 150-220 sq.ft, Daikin and Hitachi 2 ton split ACs offer powerful performance but differ in efficiency ratings, capacity, and noise levels.
Comparing 2 ton inverter models, the Hitachi 5 star AC provides a higher ISEER of 5.2 versus 4 for the comparable Daikin unit. The Hitachi is more energy efficient, with yearly consumption of 922 units over the Daikin’s 1096 units.
For maximum cooling capacity, the Hitachi edges out the Daikin again with 6200 Watts over 6000 Watts. Both can maintain desired temperature in a large living room or bedroom.
In terms of noise, the Daikin is quieter at the lowest fan speed at 32 dB compared to 37 dB for the Hitachi. But at higher speeds, they are close, with the Hitachi at 50 dB and Daikin at 49 dB for high-speed operation.
The Daikin offers superior PM 2.5 air filtration over Hitachi’s standard mesh filter for cleaner indoor air.
Both models include useful features like stabilizers, humidifiers, timers, and turbo modes. Hitachi does offer wider airflow coverage with auto-swing louvres.
Comparing 3 star units, the Hitachi again rates higher in capacity at 6950 Watts vs 7100 for the Daikin. Their noise levels and filters are similar.
The Hitachi 2 ton AC provides better energy savings and cooling capacity for large spaces, while the Daikin operates quieter and filters air better. Consider needs and room size to choose the right model.
01. Cooling Comparison
When it comes to effectively cooling a room, both Daikin and Hitachi offer strong maximum cooling capacities across 1 ton, 1.5 ton and 2 ton models.
For small rooms, the Hitachi 1 ton AC provides 3458 Watts of cooling capacity compared to Daikin’s 3520 Watts. Both can maintain set temperatures up to 120 sq ft.
In medium-sized rooms, the Daikin 1.5 ton AC edges out slightly with 5280 Watts over the Hitachi’s 5275 Watts. They utilize airflow technologies for uniform cooling in spaces around 150 sq ft.
For larger rooms, the Hitachi 2 ton AC boasts full capacity cooling of 6200 Watts versus Daikin’s 6000 Watts. Hitachi’s wider airflow distribution also allows it to more effectively cool rooms up to 220 sq ft.
When operating at partial load, both brands efficiently modulate cooling output. The Daikin 1.5 ton unit produces 2640 Watts at 50% load compared to Hitachi’s 2637.5 Watts.
An advantage of Hitachi’s Expandable+ technology is the ability to temporarily increase capacity by up to 110% during extreme heat. This quickly achieves the desired temperature.
The inclusion of turbo cool modes in both brands enables 20% faster cooling during peak summer. Dual sensors regulate appropriate compressor speeds.
Hitachi air conditioners edge out Daikin models in terms of maximum cooling capacity across capacities. But intelligent technology in both allows efficient real-world performance for a wide range of room sizes and conditions.
02. Energy Efficiency Comparison
The energy efficiency ratings of Daikin and Hitachi air conditioners show some key differences.

Should you be a Daikin or Hitachi?
When selecting a split AC for your home, both Daikin and Hitachi offer quality options, but some key differences may guide your decision.
If your top priority is energy efficiency and saving on electricity bills, Daikin air conditioners are likely the better choice. Across comparable models, Daikin ACs consistently achieve higher annual energy efficiency ratings, resulting in lower operating costs.
If you want the quietest operation, especially on low fan speeds, opt for a Daikin AC. Their sound-dampening technology makes Daikin units run 2-5 decibels quieter than Hitachi models on the lowest settings.
If you need to cool a large open space or want the power to rapidly cool areas faster, consider Hitachi. Their Expandable+ technology boosts cooling capacity up to 110% to quickly reach your desired temperature.
Hitachi also offers slightly wider horizontal air flow coverage for more effective cooling in bigger rooms. And their models tend to cost less upfront than comparable Daikin units.
So choose Daikin for efficiency and quiet operation or Hitachi for expansive cooling power and value. Both are leading brands, but factors like room size, noise tolerance, and energy use can determine the right fit.
