Panasonic was the clearest smart-feature leader among India’s 2025 ACs, LG the strongest mainstream all-rounder, and Samsung the premium comfort choice. Panasonic’s Matter-enabled models offered the broadest smart-home interoperability; LG combined ThinQ connectivity with useful energy controls and convertible cooling; Samsung’s Bespoke AI WindFree range focused on premium airflow comfort and SmartThings integration.
This is a retrospective guide to 2025 model-year air conditioners sold in India. Prices, stock, warranties and BEE labels may have changed by 2026. “Smart” here means built-in Wi-Fi, app control or documented connected-home support—not merely an inverter compressor or an “AI” label.

A genuinely smart AC should provide at least one meaningful connected function:
#1 Best Overall
- Wi-Fi Enabled: Easily control your window air conditioner from anywhere with the Frigidaire app or connect it to your Amazon Alexa or Google Home devices for smart, hands-free cooling
- Customizable Cooling: Achieve optimal comfort with custom temperature settings, 6-way directional airflow, and three different fan speeds – ideal for spaces up to 350 sq. ft.
- Easy Maintenance: Effortlessly adjust settings with the remote control and keep your AC unit working efficiently with Clean Filter alerts that notify you when it's time to clean the washable dust filter
- Energy-Efficient Performance: Maintain the set temperature and save money with Eco Mode, conserve energy and enjoy quiet operation with Sleep Mode, and remove excess moisture from the air with Dry Mode
- Effortless Convenience: Set the 24-hour on/off timer to match your schedule and benefit from the Auto Restart feature, which automatically restores the unit’s previous settings once power is restored
- Built-in Wi-Fi and remote control through a first-party app.
- Scheduling, energy monitoring or usage controls.
- App-based diagnostics or service notifications.
- Voice-assistant support through Google Home, Alexa, Bixby or another documented platform.
- Matter or another interoperable smart-home standard.
Inverter technology, convertible tonnage, auto-clean, a digital display, a remote control or “AI cooling” alone does not prove that an AC is smart. “AI” may simply describe automatic fan, temperature, occupancy or energy-control logic. Judge the specific function, not the label.
The best 2025 smart ACs to consider
1. Panasonic CS/CU-NU18AKY5WX: best connected 1.5-ton option
This 1.5-ton, 5-star Panasonic model combines built-in Wi-Fi, MirAIe app control and Matter support with 7-in-1 convertible cooling, True AI, PM0.1 filtration and four-way swing. Panasonic lists annual energy consumption at 759.55 kWh under the 2025 BEE guidelines.
Buy it if: you want Matter alongside manufacturer app control, or you will actually use scheduling, remote operation and smart-home routines.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteSkip it if: you only need basic cooling and the connected-feature premium would buy you a more efficient or better-sized conventional AC.
Matter compatibility does not guarantee that every AC function appears identically in every third-party app. Check the model’s setup instructions and supported controls before purchase.
2. LG US-Q19GWZE1: best mainstream all-rounder
The LG US-Q19GWZE1 is a 1.5-ton, 5-star model whose listed features include ThinQ Wi-Fi, Energy Manager+, AI+ Dual Inverter and HimClean. It is a strong fit for buyers who want app control and energy-management features from a familiar mainstream ecosystem.
LG also lists the US-Q19RWZE1, a 1.5-ton, 5-star model with AI Convertible 6-in-1, Energy Manager+, Diet Mode+ and AI+ Dual Inverter. Verify ThinQ support on the exact SKU: LG’s 2025 line did not offer uniform connectivity across every model.
Buy it if: you value convertible cooling, app-based energy controls and established brand familiarity.
Skip it if: Matter interoperability is essential or the selected model’s product page does not explicitly list ThinQ or Wi-Fi.
3. Samsung Bespoke AI WindFree: best premium comfort choice
Samsung’s Bespoke AI WindFree models are aimed at buyers who dislike strong, direct airflow. Compatible models can connect to SmartThings and offer functions such as remote control, AI Energy Mode and voice integration.
Samsung states that SmartThings operation requires a compatible AC, the SmartThings app, Wi-Fi and a Samsung account. Features, specifications and availability vary by model and location; therefore, do not treat every Samsung inverter AC as a smart AC.

It suits a small bedroom with a relatively low heat load. Do not choose it by floor area alone: large windows, afternoon sun, high ceilings, several occupants or a top-floor location may require greater capacity.
5. Panasonic CS/CU-NU24AKY5W: for larger, high-load spaces
This 2.0-ton, 5-star Wi-Fi and Matter-enabled Panasonic model offers 7-in-1 convertible cooling, True AI and four-way swing. Its listed annual energy consumption is 908.90 kWh under the 2025 BEE guidelines.
It is a starting point for a large living room or a space with substantial solar and occupancy load—not a substitute for a proper load assessment. Confirm outdoor-unit placement, electrical capacity and installation requirements before ordering.
6. LG 1.0-ton options for compact bedrooms
The LG US-Q12PNXE is a 1.0-ton, 3-star model with AI Convertible 6-in-1 cooling, Viraat Mode and a Dual Inverter Compressor. Its product page should be checked for the exact connectivity configuration before it is marketed as a smart AC.

You may like it so much you just might buy two!
For a connected compact-room purchase, Panasonic’s 1.0-ton model has clearer evidence of built-in Wi-Fi and Matter support. The LG may still be preferable if its price, service coverage or cooling requirements fit better.
7. Lloyd GLS18I3FWAGC: a value possibility, not a blind recommendation
Croma lists the Lloyd GLS18I3FWAGC as a 1.5-ton, 3-star, 5-in-1 convertible inverter split AC that is Wi-Fi-ready and uses a copper condenser. The available evidence is retailer-category information rather than a fully verified manufacturer specification sheet.
Consider it only when the price is materially lower and Lloyd confirms the exact app, whether Wi-Fi hardware is built in or optional, annual kWh consumption, warranty terms and service availability in your area.
8. Daikin: choose first for cooling and service, not assumed connectivity
Daikin remains a sensible alternative for buyers prioritising cooling and ownership considerations over smart-home control. Some retailer listings describe Daikin models with voice and app control, but the exact SKU and implementation must be verified through Daikin India.

BEE stars and ISEER describe seasonal efficiency, while annual energy consumption estimates how much electricity the labelled model may use under defined conditions. Neither number predicts an identical household bill.
The transition to the 2026 rating period makes simple star comparisons misleading. Samsung notes that some models could carry a rating one star lower from January 1, 2026 under the newer bands. LG lists these 2026–2027 ISEER bands:
| Rating | ISEER |
|---|---|
| 1-star | 3.50–3.79 |
| 2-star | 3.80–4.29 |
| 3-star | 4.30–4.99 |
| 4-star | 5.00–5.59 |
| 5-star | 5.60 and above |
A 2025 5-star AC and a 2026 5-star AC were assessed under different bands. Compare the label validity period, ISEER and annual kWh figure before drawing conclusions.
How to choose the right capacity
Use tonnage as a starting point, not a universal room-size rule:
- 1.0 ton: a small bedroom with low heat load.
- 1.5 ton: a typical bedroom or small living room in many homes.
- 2.0 tons or more: a larger living room or a space with strong sun, high ceilings or heavy heat load.
Also account for ceiling height, window area and orientation, insulation, top-floor exposure, occupants, kitchen-adjacent heat, humidity, frequently opened doors, city climate, voltage stability and wiring. A 1.5-ton AC is not automatically correct for a 150-square-foot room.
Smart-home compatibility checklist
- Panasonic: MirAIe and Matter on the specified models; verify supported Matter functions.
- LG: ThinQ Wi-Fi only where the exact product page confirms it.
- Samsung: SmartThings on compatible models, requiring the app, Wi-Fi and Samsung account.
- Google Home and Alexa: confirm support for the exact model and region rather than assuming it from the brand.
- Voice control: check which commands are supported; app pairing does not mean every remote function is available by voice.
Wi-Fi setup can fail when the router is 5 GHz-only, the phone changes networks during pairing, permissions or location access are disabled, the product is still bound to another account, a separate dongle is required, or the app and firmware have changed. Read the exact installation manual before scheduling installation.
Installation can matter more than the badge on the front
Require the installer to confirm:
- Correct copper-pipe length and any extra-pipe charges.
- Vacuuming of refrigerant lines before commissioning.
- Proper drain slope and a leak-free drainage route.
- A dedicated electrical circuit, suitable earthing and appropriate protection.
- Clear airflow around the outdoor unit and a secure stand.
- Outdoor-unit placement that avoids unnecessary direct afternoon sun where practical.
- Written installation details, warranty conditions and exclusions.
Installation, drilling, stands, electrical work, drainage and extended piping can materially change the delivered cost. A poor installation can increase noise, reduce cooling, waste electricity and complicate warranty support regardless of the brand.

Pick the symptom - the matching free tool is one click away.
Air-quality and high-heat claims need context
Panasonic’s PM0.1 and other filtration claims should be understood as filtration features under stated conditions, not as equivalent to a dedicated HEPA air purifier or medical protection. Similarly, LG’s and Panasonic’s high-temperature cooling claims—such as operation at 55°C—are manufacturer-stated capabilities for particular models or conditions, not independent tests of identical performance in every Indian home.
What should determine your final choice?
A practical comparison should weight cooling suitability at 25%, efficiency at 20%, smart functionality at 20%, comfort and air quality at 15%, installation and ownership at 15% and value at 5%. This avoids allowing a flashy app feature to outweigh incorrect tonnage, poor installation or weak local service.
Choose Panasonic when…
You want the deepest documented smart feature set, Matter interoperability and filtration features, and you will use connected controls.
Choose LG when…
You want a mainstream all-rounder with ThinQ, energy-management controls and convertible cooling.
