Hitachi 1.5 Ton 5 Star Inverter Split AC KASHIKOI 5100x RSB518HBEA Review

Hitachi Ltd is a multinational company that is based in Tokyo, Japan. It is one of the old and trusted companies around the globe. They manufacture products and also provide services.

This 1.5-ton inverter technology AC from Hitachi is a high-end product. It has all the necessary features of a standard air conditioner. Starting from low power consumption to working efficiently, it will not disappoint you in any sector. Let’s talk about the features, pros, and cons of this product to know more about it.

Inverter technology

This AC comes with the latest inverter technology built-in. This helps to reduce the power consumption in the long run and operates smoothly without making any noise. It’s durable and requires low maintenance as well.


This helps to spread the airflow 360 degrees all over to the room, so the cool air reaches everywhere. The high-speed fan ensures the airflow level is in your control. You can change the speed of the airflow from low to high using the remote of the air conditioner.


This AC does not require any stabilizer to run. It has a low frequency of 230V/50Hz/1Phase and is pre-installed with a stabilizer on its own. So if there is a power fluctuation, this would handle itself pretty easily and won’t let the sudden fluctuation damage internal parts.

Split design

The split design of this air conditioner gives a premium touch with the most output. The wide deflector helps to spread the airflow everywhere in the room.

What Do We like


The premium quality compressor of this Hitachi air conditioner is one of the best. The variable-speed compressor is engineered smartly to adjust the cooling and power depending on the temperature outside or heat load. This will make no noise at all and is rated as one of the lowest noise operated compressor. Also, this consumes very less electricity than most of the air conditioners.

Copper condenser coil

A condenser coil should have the maximum ability of heat transfer characteristics. Copper condenser coils are the best heat exchanger than any other. They can transfer and absorb the heat better than aluminum. Also, they are much better when it comes to cooling, and almost no maintenance is required for these condenser coils.

Energy saving

This is an energy-saving air conditioner from Hitachi. It has been rated as a 5-star energy-efficient product and consumes very less power than any non-inverter ac. It is a 1.5-kilowatt ac, and if you use it daily for about 3 hours, it will cost you only INR 700 per month, which is around INR 8400 in the whole year.

The billing amount is much higher than this in the non-inverter ones. Also, the ISEER (Indian Seasonal Energy Efficiency Ratio) value of this ac is only 4.7.


This air conditioner is environment-friendly, and it does not release any harmful gas. The refrigerant gas – R410A is not deployed by this air conditioner, and it does not harm the ozone layer in any harmful way.


This latest technology air conditioner has the timer feature built-in. You can now set to a temperature level and then set a timer before you go to sleep. What it will do is when the air conditioner reaches your selected temperature, it will automatically turn off, saving you lots of electricity consumption.

What We Don’t Like

No negative points were seen so far.


Hitachi has always promised and delivered one of the best products. This 1.5-ton air conditioner also is full of features and is environment-friendly. It is suitable for a medium-sized room to cool properly.

Copper condenser coils will require low maintenance, and the inverter technology and 5-star energy-saving feature combined will make sure that the power consumption is kept to a minimum and affordable. If the budget is not a matter, then this is one of the finest, and it is worth buying.
