LG 1.5 Ton 5 star -
Good build quality, PCB less prone to failure, comparatively less noisy(indoor unit), a decent quality remote, Gold fin coating on outdoor unit, wider services network and faster respone time.
Comparatively less peak cooling, extra parts and labor are almost 3-4x actual pricing, remote lacks backlight. Some complaints about the ac cooling going down after some months of use but i mostly suspect lack of general cleaning.
Panasonic 1.5 ton 5 start -
Some models offer PM2.0/PM0.1 air purification (may or may not be a gimmick), Comparatively very Good cooling, Wi-Fi and smart features at regular AC price, 2026 model with higher efficiency and coating on Ubends.
blue coating (Gold is considered better)
Outer body is more prone to rusting with cheaper bolts on the outdoor fan unit. Plastic body on 2024 and beforewas said to be not so good but they seems to have improved on 2025 and 2026 models, cheap feeling remote.

blue coating (Gold is considered better)

Hitachi 1.5 ton 5 star -
Good build quality, Decent cooling on their premium models, decent remote
2026 good models are not easily available on flipkart/amazon yet atleast in my location.
the once available on flipkart is the lower cooling models(4800w) the good models (5400W cooling) are mostly available offline.
A bit of cost cutting done on the outdoor 2025 outdoor copper tubes, Plastic smell on new units for a few months.
General suggestion: Get your own stand, water drain pipe, copper tubbing and extra white wrapping tape and insulation if required, everything you buy from the installation people will cost you a lot more(2-10 times more). Get your AC installed with enough clearance on the top if possible 20-30cm would be ideal it not only improves cooling efficiently but also noise levels with better air intake space. If possible get it installed in a place where there’s no direct sun exposure or rain for better durability and efficiency (Like in a balcony or under the concrete window shade preferably a easily accessible place.) Use a blower regularly to avoid frequent need for professional cleaning both on indoor and outdoor unit and just the keep the room clean. Don’t forget to the get the vacuuming done during installation, just tell them they need to do it during the appointment call itself.
Refer to Energy efficiency rating for actual cooling performance or tonnage. Diet/convertible mode don’t really matter you are only cutting on performance let the ac just do it’s thing. Air purifier filters on the ac is fairly small they just do little things. Services and installation is handled by 3rd party it’s mostly depending on the people whom you encounter.
LG installation cleaning services are done by flipkart jeeves warranty and services experience will always warry.
