Our verdict
A hot & cold 1.5 ton inverter with self-maintenance cleaning and power optimisation, listed at ₹72,800 on Carrier Midea's store. Heating output, ISEER, ambient range and warranty are not published in text.
That price is ₹27,000-31,000 above the Samsung, Voltas and Blue Star hot & cold 1.5 ton models on our list, all of which publish more of their specification. Check marketplace pricing before considering it.

What we don't
- ₹27,000-31,000 above the Samsung, Voltas and Blue Star hot & cold 1.5 ton models on our list
- The brand's product page does not publish ISEER or annual units, so its running cost cannot be checked before you buy
- 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 Indus Hot & Cold Inverter Split AC CAI18IN3R36H0 — frequently asked questions
What room size is the Carrier CAI18IN3R36H0 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 CAI18IN3R36H0 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 CAI18IN3R36H0 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.
Can the Carrier CAI18IN3R36H0 heat a room in winter?
Yes — it is a hot & cold AC that runs as a heat pump in winter. A heat pump moves heat indoors rather than generating it, so it typically uses far less electricity than a 2 kW fan or oil heater for the same warmth. Heating output falls as the outdoor temperature drops, so it is best suited to plains winters rather than hill-station cold.
Where can I buy the Carrier CAI18IN3R36H0 at the best price?
We list ₹72,800 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.
