Voltas 1.5 Ton 5 Star Window AC (Copper, 185 LZH, White)

Find latest price (Amazon)

  • Excellent Cooling
  • Budget-Friendly Pricing
  • Good energy efficiency

  • A bit noisy
  • All functions in remote don’t apply to this model.

Backed by the solid reputation and brand value of Voltas, this is one of the best air conditioners that is a killer deal for both you and your pocket. With 1.5-ton capacity, the gadget is ideal to cool any small and medium-sized room of about 120 to 200 sq. ft area effortlessly.

Not only does it come to you at a cost-effective price but being a 5 star AC continual energy costs are also low. Being ultra-rich with features, you will feel it justified at catching the first spot.

As mentioned, it has a 5 Star rating and thus you can be confident of getting the minimum energy bill. The AC consumes just about 0.72 unit per hour which is a commendable factor. However, the ISEER value is just 3.31 which means it is just enough to pass the 5-star rating mark.

Even though the AC lacks the inverter technology, it has high ambient cooling and turbo mode option which can instantly cool the room if you do not wish to give 5-10 minutes to the machine for cooling in the normal mode.

Fresh air becomes an issue in rooms with air conditioners as all windows need to be closed. However, this AC has vents which keep pushing fresh air inside the room. Thus, the cool breeze from the machine has an extra edge of freshness.

To maintain the freshness of the air, this air conditioner packs some extra features like the Anti-Dust filter, Silver Nano or negative ion filter and dehumidifier. They not only remove all contaminants from the room but also remove extra moisture from the room automatically- thanks to its sensors.

The air conditioner boasts of other premium features like copper condenser coil, auto-swing mode, a timer to conveniently turn the AC on or off by merely setting the time and the sleep mode to maintain uniform and optimum temperature while you are sleeping through the night. Its LED Panel and glow light panel ensures that you can check on the AC even in dark. The LCD remote is a convenience that is always welcome.

The air conditioner has a self-diagnosis feature that can indicate in case you need to call in a technician. However, with a one-year warranty on the whole unit and five years warranty on the compressor, this is a unit that will serve you for years without much trouble. The after-sales service of the brand has also won accolades from the customers.

The only flip side to this machine is that you might yearn for few more smart features like the heat option. Nevertheless, very few machines of 1.5-ton capacity can beat this affordable and terrific performing air conditioner.

LG 1.5 Ton 5 Star Wi-Fi Inverter Window AC Copper, 2020 Model, JW-Q18WUZA

Find latest price (Amazon)

  • Excellent Cooling
  • Budget-Friendly Pricing
  • Good energy efficiency

  • No Auto Mode
  • No option to switch off the vertical swing

When you compare split ACs and Window ACs, you always find that while the former has evolved with time to have advanced smart features, window ACs remain ridiculously old fashioned.

LG has brought about a change in this aspect by introducing in this window AC, a new design, Wi-fi connectivity and integration with Alexa and Google Assistant. Using the Smart ThinQ app, you can control the AC, monitor energy consumption, change modes etc. In addition, it has a dual inverter compressor for better energy efficiency and lower noise and 4-way air circulation too.

The window AC comes with an ISEER value of 3.5 and an energy rating of 5 stars. The annual energy consumption is 1106 units. So, it comes to around 0.7 units per hour under ideal conditions. Compared to other window ACs, LG JW-Q18WUZA highest in terms of energy efficiency.

As mentioned earlier, the window AC comes with a dual inverter compressor, which means two rotors rotate at opposite frequency. This results in better compression of the refrigerant, ability to work at a wider range of RPM and thus operate at variable tonnage. It also helps achieve better cooling efficiency at lower noise. In fact, it makes just 44 dB noise whereas most window ACs make noise closer to 50-52 dB.

Yet another advantage of this model is that it has copper condenser coils that have Ocean Black protection. What this means is that the coils have a corrosion-resistant black coating that repels water and also protects the condenser from moisture, salt, smoke and other pollutants.

Design-wise, LG claims that the horizontal vents at the top help in better cooling. But, in reality, we hardly find a difference here.

Just like other LG appliances, it too has a smart diagnosis system that helps identify error codes easily. The AC also has a Clean Filter indicator that alerts you when it is time to clean the filter.

Overall, with excellent design, various modes, timer, LED display and remote control operations, it is one of the best window ACs you can buy in the market.

Blue Star 1.5 Ton 5 Star Window AC (Copper, 5W18GBT, White)

Find latest price (Amazon)

  • Excellent in terms of performance and durability.
  • Apt for coastal areas where summer is humid.
  • Auto mode helps cool optimally and saves energy.

  • Comparatively expensive

Blue Star is one of the trusted brands when it comes to air conditioners. This 1.5-ton window AC is appropriate to cool a room as big as 170 Sq Ft. 

The AC has a 5-star energy rating and ISEER value of 3.4 It consumes 1161 units of electricity annually. This means, about .72 unit of electricity per hour, which is a bit high comparatively.

Coming to its maintenance, it fares on the lower end. This window AC has the indoor front panel unit that can be conveniently detached for periodic cleaning. This helps in reducing the maintenance in the long run. 

One of the best features we love about this AC is the antifreeze temperature control on the indoor coil, which is a safety feature. It kills the compressor when the unit is set at a shallow temperature and runs in cool mode. This prevents frost from forming on the heat exchanger, thus, protecting the unit.

It has multiple modes, such as dry cooling during the monsoons, which ensures reduction of excessive humidity within the room, so you stay comfortable when cooling the environment. During summers, it not only helps cool down the room but also reduces the stickiness typically found in coastal regions and cities like Mumbai.

The auto mode for intelligent cooling automatically selects the cooling program that is optimal for current weather conditions, keeping you comfortable.

The included LCD remote has a night glow function which allows you to easily operate the remote even in pitch darkness without blinding yourself. 

Speaking about the noise level, it ranges from 48 dB(A), on the lower end, to 52 dB(A) on the higher end. The noise levels are average on the lower end while it may be a bit noisy on higher settings. 

Being a 5 star AC, the long term running cost will be moderate as energy consumption will be lesser in the long run. So, even though you are paying a premium price upfront, in the long term, it would turn out to be a much better choice. 

Godrej 1.5 Ton 3 Star Window AC (Copper, AC 1.5T GWC 18UTC3-WSA, White)

Find latest price (Amazon)

  • Has dust filter and anti bacterial filter to remove dust and odor
  • Fairly good energy efficiency and cooling
  • Fairly silent

  • Remote doesn’t have temperature display

The 1.5T GWC 18UTC3-WSA is the most feature loaded window AC on this list. Given that it’s a 1.5 ton AC, rooms as large as 180 Sq. Ft can use it even when ambient temperature is high.

The AC has a 3-star rating and consumes about 1265 units of energy annually. That comes to 0.80 units per hour.
Additionally, thanks to the inverter compressor, energy consumption is lower when the AC is used for an extended duration. The inverter compressor also enhances the durability and performance of the AC.

As with most ACs sold in the Indian market, it has a 100% copper condenser. Additionally, it has a special anti-corrosive Bluefin coating on the evaporator & condenser that protects it from rust and corrosion. 

This AC comes with multiple features such as precise cooling and anti-dust filter, which removes dust, hair, pollen, etc and lowers the maintenance cost. 

A few other special features that are worth mentioning include turbo cooling, anti-freeze thermostat, a special health filer called Micro Mesh Filter and an active carbon filter. 

Moreover, if you are the one who has deep concerns to save the planet, then this is the sure deal due to its R32-Refrigerant. 

Godrej also prides on the fact that this AC has silent operation thanks to its Multi-layered Acoustic jacket for the compressor. This jacket not only blocks the noise but also protects vital components from damage. 

A downside that we mention about this AC is the fact that its remote does not have an LCD display, so at night you cannot tell the temperature by simply looking at the remote. 

Given its wide array of features, you should definitely shortlist this AC if you’re in the market for a 1.5-ton window AC. Although it has only a 3-star rating, the inverter technology of the compressor makes sure that your electricity bills do not crash through the roof. 

Carrier 1.5 Ton 5 Star Window AC (Copper Estra Neo CAW18SN5R39F0 White)

Find latest price (Amazon)

Carrier is one of the reputed brands in the air conditioning industry. The Estra Neo model with 1.5-ton capacity and 5-star energy efficiency is a pretty good option for a home or office which uses AC for a small duration of the day.

The Window AC comes with ISEER value of 3.35 which is just above the minimum requirement for a 5-star window AC. It has an annual energy consumption of 1220 units.

In order to improve energy efficiency, the AC shuts off the fan along with the compressor when the desired temperature is reached. In order to ensure the room doesn’t get warm, it switches back on within a maximum of 3 minutes. While this does ensure better energy efficiency, the drawback is that durability could be affected due to constant switching on and off. But then again, this is an aspect seen in all non-inverter compressor AC and is not limited to just Carrier Estra Neo.

Talking about the cooling efficiency, most users report it to be highly satisfactory. The AC has 2-way louvre swing so that air reaches all corners. The fan speed has 3 levels of adjustment too. To improve air quality, it is equipped with a dust filter, activated carbon filter, zeolite filter and electrostatic filter. 

Carrier Estra Neo also has Dry mode which helps remove excess moisture in the air, typically experienced in hot coastal summers.

The AC also has other commonly found features like timer and sleep mode. In sleep mode, the temperature increases little by little gradually to maintain a comfortable temperature and reduce energy consumption.

As it uses R32 refrigerant gas, environmental impact is also minimal.

Talking about the drawbacks, users are of the opinion that it is a bit too loud. Even in the lowest fan level, it produces 50 dB while at highest speed level it makes 56 dB. A few also say that it appears a bit plasticky and is not as elegant as many other competitor brands.

Overall, given the excellent brand reputation and cooling efficiency, it could be very well suited for homes where AC is used for a minimal time.
