AC Insider - Inverter AC Comparison and Buying Guide

  So, in this comparison I put both the LG 1.5 Ton 2026 Model AS-Q19YNZE1 — and the Model US-Q19YNZE3 — side by side, so that you can take better decision before buying. Both these models are sitting in same capacity bracket and also same star rating bracket, but when you go deep inside the technical things, many differences are coming out — like compressor technology is different, energy efficiency numbers are different, VIRAAT mode capacity is different, and also price is different. I personally used and tested both the units so I can give you real information, not only copied from brochure.

 If you are confused between Carrier 1.5 Ton 5 Star and Carrier 1.5 Ton 3 Star inverter AC, then you have landed on right page. I have been testing both these units — the Carrier 1.5 Ton 5 Star Wi-Fi Flexicool Inverter Split AC (ESTER EDGE Gxi WiFi – CAI18EE5R36W0) and the Carrier 1.5 Ton 3 Star Flexicool Inverter Split AC (ESTER EDGE Gxi – CAI18EE3R36F0) — for quite some time now and I want to share what I found during my testing. Both models are from same ESTER EDGE Gxi series of Carrier, and they come with same inverter compressor platform, same Convertible 6-in-1 FlexiCool technology, and same R32 eco-friendly refrigerant. But the gap between 5 Star and 3 Star BEE rating is not just about sticker on the unit — it actually shows up in real world power consumption and running cost which many people don't realize before purchasing.

   So I have been using both of these AC units from Hitachi since last two months, and I think now I have enough real experience to write this full comparison. The Hitachi 1.5 Ton 5 Star Inverter Split AC (RAS.V518PCDIBT) is costing close to ₹45,500, and the Hitachi 1.5 Ton 3 Star Inverter Split AC (RAS.D318PCD2BS1) is available around ₹36,500 — so there is ₹9,000 rupees difference between them. Both of them are 1.5 ton capacity and both are suitable for medium sized rooms between 111 to 150 sq.ft., so the question is — is 5 Star model really worth that extra money or not?
