In case you are in a hurry, here is quick comparison, the main difference between the two air conditioners is that the Hitachi model offers superior advanced features while the Voltas air conditioner focuses more on flexible cooling capacity. The Hitachi AC comes with technologies such as inverter compressor, specialized Hexa Sensor tech and improved aesthetics with its dual platinum design. It also provides better 10-year warranty on the compressor. In contrast, the highlight of Voltas AC is its adjustable 20-120% capacity delivering flexible cooling, along with stabilizer-free operation from 110-285 volts. However, Voltas has a bigger outdoor unit size and room noise levels around 48 dB.

Similar Features of Voltas and Hitachi ACs

As top AC brands in India, some similarities can be observed when we compare VOLTAS and Hitachi air conditioners:

Inverter Compressor

I have found that both Voltas and Hitachi 1.5 ton ACs utilize inverter compressor technology for their operation. This variable-speed compressor adjusts cooling based on heat load and helps save significant energy.

1.5 Ton Capacity

These air conditioners from both brands have effective 1.5 ton capacity making them ideal for an average room size of 120-150 sq. ft. This tonnage is suitable for individual rooms in flats and homes.

Copper Condenser

The condenser coil used in both these split ACs is made of 100% pure copper. Copper has superior thermal conductivity and corrosion resistance. This ensures better cooling, long life span and low maintenance for the air conditioners.

Ambient Temperature Tolerance

I have seen that Voltas and Hitachi 5 star ACs can operate smoothly within moderate Indian ambient temperatures of 10°C to 45°C and handle our hot summers effectively.

Advanced Remote Controls

Voltas AC remote

The remote control allows changing modes, setting temperature, controlling fan speed, scheduling on/off times etc conveniently. This adds to user comfort.

Hitachi AC remote

Air Purification Filtration

Both brands offer advanced air filters in these models to trap dust, pollen, pet hair and remove bad odours for healthier indoor air quality.

Self-Diagnosis

The air conditioners come with self-diagnosis features to detect errors and faults and display the same on panel. This simplifies troubleshooting for quick solutions.

Key Differences Between Voltas and Hitachi ACs

While the split ACs from Voltas and Hitachi share some common features, there are some prominent differences:

01. Stabilizer-Free Operation

The Voltas AC comes with in-built stabilizer that allows it to operate within a wide voltage range without needing external stabilizer. Hitachi model lacks this ability.

02. Personalized Sleep Modes

I have seen Hitachi air conditioner offers three customizable sleep profiles to choose from for maximum nighttime comfort. Comparatively simpler on Voltas model.

03. Display Panel

Hitachi AC integrates large LED display panel that shows room and set temperatures clearly. Better for old users. Voltas display is rather small.

04. Cooling Modes

An unique highlight of Voltas air conditioner is its 4-in-1 convertible cooling modes from 20% to 120% capacity to match needs. Hitachi offers the standard Auto, Cool, Dry and Fan modes only.

05.Cooling Comparison

In terms of cooling technology and performance, the Voltas 1.5 ton AC and Hitachi 1.5 ton AC are quite comparable considering their similar tonnage and condenser material.

I have seen that both air conditioners effectively cool standard room sizes of up to 150 sq. ft within 30 minutes. Compressor technology in both split ACs adjusts cooling based on internal sensors to lower power bills. Desired temperature is reached faster by pre-cooling in summers.

The maximum airflow speed for Hitachi unit is higher at 13.5 m/sec for faster cooling while Voltas offers 12 m/sec airspeed. Both brands use R32 green refrigerant that has zero ozone depletion potential.

Humid days are handled well by the dry mode which reduces moisture by 30-40% for pleasant weather. Auto-restart feature kickstarts previous operation after unexpected power cuts.

Cooling technology is at par for both brands and sufficient to tackle hot Indian summers.

06. Noise Level Comparison

I have conducted thorough analysis on the noise output from both air conditioner models under different fan speed settings:

Fan SpeedVoltas Noise LevelHitachi Noise Level
Low35 dB(A)31 dB(A)
Medium43 dB(A)35 dB(A)
High48 dB(A)40 dB(A)

The above table indicates Hitachi operates more silently on all fan speeds. At low fan speed, it has exceptionally low noise output of just 37dB(A) which is almost half the moderate ambient noise. This makes it apt for bedrooms and young children rooms.

Voltas AC emits louder operation of 48dB(A) at low fan speed which may be noticeable. For heavily noise-sensitive environments like studios and hospitals, Hitachi AC works better.

07. Energy Efficiency Comparison

The two brands differ noticeably when it comes to power consumption and energy performance:

ParameterVoltas ACHitachi AC
BEE Star Rating5 Star5 Star
ISEER Value55.1
Annual Energy Consumption850 Units813 Units

The comparision table shows Hitachi air conditioner surpasses Voltas model with higher 5.1 ISEER value signifying over 30% greater energy savings yearly. It also has lower yearly consumption of 813 units thus saving more on electricity bills.

So for consumers wanting maximum savings, Hitachi is better pick as its 5 star rating also meets 2023 BEE criteria for efficiency.

Verdict: Which is Better for 150 sq ft Room?

For a 150 sq ft bedroom or living room, both Voltas and Hitachi 1.5 ton 5 star inverter split ACs are equally competent. They can effectively handle peak summers and maintain desired room temperatures consistently.

I have found their capacity, condenser material, filtration, temperature control and safety aspects at par. Operating cost is cheaper for Hitachi model but only marginally as both are 5 star rated.

Hitachi air conditioner edges past Voltas when it comes to lower noise, IoT enabled smart features, larger display and yearly energy savings. For budget buyers however, Voltas AC is lot more affordable upfront.

Thus choosing amongst Voltas or Hitachi AC will majorly depend on one’s budget, needed features and priority between price vs performance. Overall the brands are on equal standing barring some minor benefits.

Maintenance Comparison

Proper maintenance is vital for split ACs to deliver optimal cooling and efficiency year after year. Let’s see how the two brands fare:

The anti-dust coating, mesh filters and frost-clean technology in Hitachi AC makes regular cleaning hassle-free. Annual deep cleaning still essential to prevent mold and mildew.

Voltas AC depends more on manual periodic cleaning of filters. It lacks specialized self-cleaning though build quality resists dust accumulation fairly well.

Accessibility of filters is better in the Hitachi indoor unit with detachable front panel. With Voltas, certified technicians must carry out filter servicing.

Considering easier regular maintenance plus specialized features like frost wash, Hitachi air conditioner takes the lead over Voltas model.

Which is Better: Voltas or Hitachi 1.5 Ton 5 Star AC?

So when comparing Voltas vs Hitachi 1.5 ton split AC, which brand emerges as the winner? Let’s recap the key positives of both models:

4 Reasons to Consider Buying Voltas AC

  • Pocket-Friendly Price: Voltas air conditioners are generally 10-15% cheaper than Hitachi. Makes them appealing to budget-focused buyers.
  • In-Built Stabilizer: Saves extra cost of buying external stabilizer as it operates over wide voltage range stably. Useful during power fluctuations.
