Our verdict
An inverter window AC with a dust filter and adaptive airflow, listed at ₹45,090 on Carrier Midea's store. Like the rest of Carrier's range, its page does not publish ISEER, annual units, cooling capacity or warranty in text.
Lloyd's 1.5 ton 3-star inverter window AC publishes all of those figures and costs ₹12,000 less on Lloyd's store, so the Carrier is hard to recommend at current store pricing.
What we like
- One box, no outdoor unit — it moves with you to the next flat without a split AC's reinstallation bill
- Inverter compressor — unusual in a window AC, and cheaper to run over long hours than a fixed-speed window unit
What we don't
- Lloyd's 1.5 ton 3-star inverter window AC publishes its figures and costs ₹12,000 less
- The brand's product page does not publish ISEER or annual units, so its running cost cannot be checked before you buy
- Louder than a split, and needs a window or wall opening of the right size
- Compressor and PCB warranty terms are not stated in text on the product page — confirm before buying
When this is not a good choice
Every condition below is derived from this product's published specifications and from how it compares with the air conditioners we track — so you can check each one against your own room, supply or budget rather than take our word for it.
You live outside a metro or a major service town
Carrier's service network is rated good rather than excellent. Filter availability and callout times are what decide whether a purifier is still running in five years, and they are worth checking for your pin code before you buy.

About Carrier
The brand of the company that invented modern air conditioning, sold in India's residential market by Carrier Midea India. The name carries weight and the range covers split, window, hot & cold and Wi-Fi models, but the Indian store is the weakest in the category for published specification: ISEER, annual units, rated capacity and warranty are shown only as images or not at all, and brand-store prices sit well above rivals that publish their figures.

Carrier 1.5 Ton 3 Star Estrella Inverter Window AC CAW18EC3R36F0 — frequently asked questions
What room size is the Carrier CAW18EC3R36F0 suitable for?
Rated at 5,276 W nominal, it suits a middle-floor room of up to about 200 sq ft with a 10 ft ceiling, or about 140 sq ft on a top floor with strong afternoon sun. Each person beyond two adds load, and a room open to a kitchen needs more. Our AC tonnage calculator works this out for your exact room.
How much electricity does the Carrier CAW18EC3R36F0 use?
Carrier's product page does not publish the ISEER or the BEE annual-units figure for this model, so its running cost cannot be calculated from the brand's own information. Both numbers are printed on the BEE star label on the unit itself — ask the seller for a photo of the label before you pay, and compare the annual units against the 3-star models on our list that publish them.
What warranty does the Carrier CAW18EC3R36F0 come with?
Warranty terms are not published in text on Carrier Midea's product page. Warranty on an inverter AC matters most for the compressor and the PCB, the two most expensive parts to replace, so check both are listed on your invoice and register the product with Carrier after installation.
Where can I buy the Carrier CAW18EC3R36F0 at the best price?
We list ₹45,090 from Carrier Midea India official store on 2026-09-14. AC prices move weekly and are often lower on Amazon and Flipkart, especially in bank-offer weeks, so compare all three before buying — and check what installation is included, because extra copper pipe and an outdoor stand are usually charged separately.
