AC installation charges and running cost India

Work out what your AC or geyser will cost, from showroom to electricity bill

A room air conditioner or water heater has three prices: what you pay at purchase, what the installer adds on the day, and what your electricity meter adds every month for ten years. These guides break each one down with illustrative rupee arithmetic, and explain the BEE label, GST, warranty and complaint rules around them.

  • Pick tonnage and star rating from your room, hours of use and electricity slab
  • Know which installation charges are standard and which are extras like copper pipe and stands
  • GST on room ACs fell from 28% to 18% on 22 September 2025; check your invoice

AC and water heater types compared

TypePurchase and running cost patternGood forWatch out for
Fixed-speed split ACUsually cheaper to buy than inverter; compressor switches fully on and off, so units used depend strongly on hours and settingRooms used for short periods; tight budgetsFewer models in higher star bands; temperature swings; check the label validity year
Inverter split ACUsually costs more upfront; variable-speed compressor tends to use fewer units over long daily useBedrooms and living rooms used many hours a dayPCB repairs can be costly outside warranty; voltage protection and good installation matter
Window ACLower purchase and installation cost; no copper pipe run; usually fewer high-efficiency modelsRented homes, rooms with an existing window openingNoisier indoors; needs a suitable window or wall cut-out; lower star options limited
Portable ACModerate price; usually lower efficiency for the same capacityTemporary use where fixed installation is not allowedExhaust hose must vent outside; often struggles in large or hot rooms

Frequently asked questions

What GST applies to a room AC in India now?

Room air conditioners (HSN 8415) moved from 28% to 18% GST from 22 September 2025 following the 56th GST Council meeting. Installation charged as a separate service is generally billed with GST as well. Check that your invoice shows the GST rate and amount separately.

Which tonnage do I need for my room?

A common rule of thumb is about 1 ton for a small bedroom up to roughly 120 sq ft and 1.5 tons for about 120–180 sq ft, but top-floor rooms, west-facing walls, high ceilings, many occupants and hot cities need more. See the tonnage guide for a heat-load style check.

Is a 5-star AC always worth the extra price?

Not always. It depends on how many hours you run it and which tariff slab your extra units fall into. Long daily use in a hot city usually favours a higher star band; a guest room used occasionally may not recover the price gap. Use the payback calculator.

Why is my AC installation bill higher than the 'free installation' promised?

Free or standard installation usually covers a fixed pipe length, mounting and basic drain work. Extra copper pipe, an outdoor stand, core cutting, extra drain pipe and electrical work are often charged separately. Ask for the rate card before installation and check the pipe length used.

How many units does a 1.5-ton AC use per month?

It depends on the model's efficiency, room heat load, thermostat setting and hours. The BEE label's annual units divided by its assumed operating hours gives a per-hour figure you can multiply by your own hours. See the electricity bill guide.

What can I do if a brand will not honour my AC or geyser warranty?

Complain in writing to the brand's service centre and keep the complaint number. If unresolved, contact the National Consumer Helpline on 1915, and then file a consumer complaint on e-Jagriti under the Consumer Protection Act, 2019. See the official routes guide.

Is a heat-pump water heater better than a geyser?

A heat-pump water heater uses much less electricity for the same hot water but costs much more to buy and needs space and airflow. It suits high daily use. The heat pump payback guide shows the arithmetic.
