Costs, Star Ratings and 2026 Rules
AC and geyser price in India: what actually decides the cost
The factors that set the price of a split, window or inverter AC, a geyser or a heat-pump water heater in India, from tonnage and star rating to GST and installation.
The price you pay for a room air conditioner in India is decided mainly by capacity (tonnage), energy efficiency (BEE star band and ISEER), compressor type (fixed-speed or inverter) and format (split, window or portable), with features, condenser coil material and warranty terms adding smaller amounts. For water heaters, the drivers are type (storage, instant, gas, solar or heat pump), tank size, tank and heating element build, and for electric storage geysers the BEE star label. On top of the product price come GST (18% on room ACs since 22 September 2025), installation extras and, over the years, the electricity bill, which for an AC used daily often adds up to more than the purchase price.
This page is the overview for the section. Each factor below links to a detailed guide. All rupee figures are illustrative examples, not market prices. This site does not rate or recommend brands.
The three prices of an AC or geyser
Think of any cooling or hot-water appliance as having three separate costs:
| Cost layer | What it includes | When you pay |
|---|---|---|
| Purchase price | Product, GST, delivery | At the store or online checkout |
| Installation | Basic fitting, extra copper pipe, stand, core cutting, electrical work, GST on the service | On installation day |
| Running and upkeep | Electricity units, servicing, AMC, gas top-up, repairs outside warranty | Every month and every year |
A buyer who compares only the first row often ends up paying more overall. A cheaper, lower-efficiency AC in a room used ten hours a day can cost more over its life than a pricier efficient one. The total cost worked examples put all three layers together.
Factor 1: tonnage (cooling capacity)
AC capacity in India is sold in tons of refrigeration. One ton equals 12,000 BTU per hour, or about 3.5 kW of cooling. Common room AC sizes are 0.75, 1, 1.5, 2 and 2.5 tons. Larger units cost more to buy, usually draw more power, and need thicker copper pipes.
Undersizing is the common mistake: an AC too small for a hot top-floor room runs at full load for hours and never reaches the set temperature. Oversizing wastes money and, in fixed-speed units, cycles on and off too often, leaving the room clammy. The tonnage and room size guide explains how to size from the heat load.
Factor 2: star rating and ISEER
Room ACs sold in India carry a Bureau of Energy Efficiency (BEE) label with a star band from 1 to 5. The rating is based on the Indian Seasonal Energy Efficiency Ratio (ISEER), which estimates efficiency over a typical Indian year rather than at one test temperature. A higher ISEER means more cooling per unit of electricity.
Higher star bands usually cost more because they use bigger heat exchangers, better compressors and inverter control. BEE revises the star tables periodically, so a model labelled 5-star under an older table may fall in a lower band under a newer one. Always check the label period printed on the label. Details are in the BEE label guide.
Factor 3: inverter or fixed speed, split or window
An inverter compressor varies its speed to match the cooling needed; a fixed-speed compressor switches fully on and off. Inverter models generally cost more upfront and save more units when the AC runs for long hours. Window ACs have no separate outdoor unit or copper run and cost less to install, but are noisier and offer fewer high-efficiency models. Split ACs are quieter indoors and more flexible to place. See split, window and inverter ACs compared.
Factor 4: smaller product features
| Feature | Effect on price | Does it change running cost? |
|---|---|---|
| Copper vs aluminium condenser coil | Copper often costs more | Mainly affects repairability and corrosion behaviour, not the label figure directly |
| Anti-corrosion coating on outdoor coil | Small premium | Can matter near the sea or in polluted cities |
| Wi-Fi control, filters, sensors | Small to moderate premium | Only if you use schedules or eco modes |
| Convertible capacity modes | Small premium | Can reduce units if you choose lower modes |
| Longer compressor or PCB warranty | Often bundled in higher-priced models | Lowers repair risk, not electricity |
Water heaters: what drives their price
Water heaters vary more by type than ACs do:
- Electric storage geysers (typically 10 to 35 litres for bathrooms) are priced by tank size, tank lining, heating element and BEE star label. The label reflects standing heat loss.
- Instant electric heaters (1 to 6 litres) are cheapest but draw high power while running.
- LPG or PNG gas geysers are inexpensive to run where gas is cheap but need ventilation and a trained fitter.
- Solar water heaters cost more to buy but very little to run in sunny months.
- Heat-pump water heaters cost the most among electric options but use far fewer units for the same hot water.
The water heater types guide explains each.
Taxes and rules that change the bill
- GST: Room ACs (HSN 8415) are at 18% from 22 September 2025, down from 28%. Solar water heaters moved to 5%. Check the rate shown on your invoice for other items. See the GST guide.
- MRP: Under the Legal Metrology (Packaged Commodities) Rules, 2011, the MRP printed on a packaged product is inclusive of all taxes. A dealer cannot charge above MRP for the product.
- Refrigerant: The gas used (R-32, R-410A or R-290 in newer units; R-22 in old ones) affects servicing and gas top-up costs. See the refrigerant basics guide.
Illustrative example: two 1.5-ton quotes
| Item | 3-star fixed speed (illustrative) | 5-star inverter (illustrative) |
|---|---|---|
| Price including 18% GST | ₹34,000 | ₹44,000 |
| Installation extras | ₹3,500 | ₹3,500 |
| Electricity per year (1,200 hours, ₹7 per unit) | ₹8,400 | ₹5,900 |
| Total over 8 years | ₹1,04,700 | ₹94,700 |
In this example the efficient model costs ₹10,000 more at the store but about ₹2,500 less each year to run, so it comes out about ₹10,000 cheaper over eight years. With 300 hours a year the result reverses. Run your own numbers in the payback calculator.
FAQ
Is a higher-priced AC always more efficient?
No. Price also reflects features, brand positioning and warranty. Compare the ISEER and annual units on the BEE labels of the two models directly.
Does the AC price include installation?
Often the product price includes a basic installation, but extras like copper pipe beyond the standard length and an outdoor stand are billed separately. Ask before buying.
Should I buy before summer to save money?
Prices and offers vary through the year, and installation slots are tighter in peak summer. There is no rule that guarantees a lower price in any month; compare written offers.
