Window AC 1.5 ton

[Jonas]

This is for a bedroom and will be used primarily during nights.

I was wondering if spending more on a dual inverter AC would be worth it if the AC was running for about 8 hours in a day.

Any recommendations?

Hard to say... Not used one before.
But there should definitely be some reduction than using a non inv window AC.
If you are running it at 18C, then it definitely goes out of the window for a Window AC, inv or non-inv

I think only one window AC has a decent ISEER, the LG Dual Inverter Window AC. It cools well in Mumbai's heat. You can check it out here: LG DUAL Inverter Window AC(1.5), 5 Star with Convertible 4-in-1 Cooling with Ocean Black Protection : buy online | LG India. Look for the latest year model.

One major drawback of LG window ACs is that the air vents are at the top. If you mount it above the door, it’s gonna be cooling the ceiling. I read this review somewhere

Voltas bluestar and carrier also have inverter window ac models.

So I’m considering getting an LG Window or Split AC. I’ll be checking tomorrow if the existing window (the top frame is only 40 cm in heights) can accommodate this model:

Limited-time deal: LG 1.5 Ton 5 Star DUAL Inverter Window AC (Copper, Convertible 4-in-1 cooling, RW-Q18WUZA, 2023 Model, HD Filter with Anti-Virus Protection, White) Amazon.in

Or else will get a split AC. This model:

Limited-time deal: LG 1.5 Ton 5 Star AI DUAL Inverter Split AC (Copper, Super Convertible 6-in-1 Cooling, HD Filter with Anti-Virus Protection, 2023 Model, RS-Q19YNZE, White) Amazon.in

My question is: does LG offer additional warranty just like Voltas did?

 

[Jonas]

So I’ve two options now.

LG 5 star dual inverter 1.5T window AC which is monstrous 17x26 inches or LG 3 star dual inverter 1.5T window AC which seems to be of standard size 15x26.

This AC will be running 8-9 hours a day. Which one will you guys recommend? I mean, will there be a significant difference in terms of energy savings?

Would you be running it for the entire year or just the summers? If usage is less go with the 3* else 5*.

 

[Jonas]

Just the summers at night. 7-9 hours max.

 

[Tejas01]

3* should be fine then.

After initial cool if you ll put it at lowest mode then difference would be negligible.
Inverter ac at lower mode become a lot more efficient. Like at 50% cooling capacity it consumes 33% energy approx. So that consumption difference also becomes 1/3rd.
