RishiGuru...need your expert advice.
I am no expert, but will try to help you out.
I am torn between a LG 1 ton BS-Q12GD8R4 and a Sharp 1.1 ton Sharp AH-XP13LV. The dealer is quoting 36K for LG and 33K for the Sharp with 1700 as installation charges.
First I don’t know LG has a 1 Ton Inverter model named BS-Q12GD8R4. But there is a LG BS-Q12B8R4 model which matches your said EER. So I am considering this unit from hence onwards.
I know that the compressor technology of the Sharp is older while the LG is a newer one which should help it to be more efficient.
On the contrary it is just the opposite for the two models you are comparing.
My question is is the new technology worth the extra 3K if the cooling and/or power consumption remains the same. I have read the brochures of both and the EER of the LG is at 3.47 while the EER of the Sharp is at 3.67.
Let’s have a look at the Sharp and LG specification:
LG BS-Q12B8R4
Cooling Capacity Range [kW]: (0.83 - 3.4 - 4)
Cooling Capacity Range [BTU/Hr]: (2,821 - 11,600 – 13,780)
Cooling Capacity Range [Ton]: (0.24 – 0.97 - 1.14)
Rated Cooling Capacity: 3.4 kW
Rated Power Consumption: 980 watts
Rated EER (W/W): 3.47
Max Outdoor Operating Temparature: 46 °C
Refrigerant Gas: R410A
IDU Weight: 9.5 kg
ODU Weight: 24 kg
Sharp AH-XP13LV
Cooling Capacity Range [kW]: (0.8 - 3.67 - 4.20)
Cooling Capacity Range [BTU/Hr]: (2,732 - 12,531 - 14,341)
Cooling Capacity Range [Ton]: (0.23 - 1.04 - 1.20)
Rated Cooling Capacity: 3.67 kW
Rated Power Consumption: 1010 watts
Rated EER (W/W): 3.63
Max Outdoor Operating Temparature: 46 °C
Refrigerant Gas: R410A
IDU Weight: 9 kg
ODU Weight: 28.5 kg
It seems the Sharp have an upper hand in every single department in terms of cooling capacity to LG model be it minimum, rated or maximum cooling capacities. The Sharp will provide you a more powerful cooling under rated condition while maxing out to a 1.2 Ton. The LG can do a max of 1.14 Ton. The Sharp also wins in having an even lower minimum cooling capacity ceiling of 0.23 Ton thus consuming slightly less energy when the set temperature is achieved while the LG can do the best of 0.24 Ton.
And even though the Sharp is more powerful than this LG, it consumes nearly equal energy, thus reflecting a higher cooling performance having an EER of 3.63 while the LG can do a best of EER of 3.47. With LG Inverter having lower performance capabilities while costing INR 3K more, the Sharp model is in a win-win situation.
My question is is the new technology worth the extra 3K if the cooling and/or power consumption remains the same. I have read the brochures of both and the EER of the LG is at 3.47 while the EER of the Sharp is at 3.67.
If both used to cost the same I would have told you to pick the one you like since you are swaying for LG, but that being not the case Sharp wins hands down in terms of better cooling capacity as well as better cooling performance.
While the figures are staring at me in the face what worries me is if I getting good value for money?
Sharp Inverter air conditioners are the kings of VFM. That is the reason why I bought it first place.
Also is the question of Sharp A.S.S. All other stuff like the fridge, TV and washing machine at my home is LG and we've never ever had any issue with it. So, I'm swaying for the LG a little more than the Sharp. But when I look at the 3K price difference and the EER- I don't know what to choose. Please advise. Thanks
ASS is very important. If Sharp have good ASS in your locality, gun for Sharp AH-XP13LV eyes closed. If not then LG.
At the end of the day you will be happy with any one of the two air conditioners. But comparing between the two the Sharp model is definitely superior and hence the winner.
Hope it helps.
