Introduction

This pack is the working file for buying and running an air conditioner in India. The free guides on Claude AC explain each question separately; this document puts them in the order you meet them, with worksheets to fill in: cooler or AC for each room, the tonnage, what the BEE label really tells you, what the machine adds to your bill at your own slab rate, what the price includes, how a correct installation looks, how to keep the warranty valid, and what backup can and cannot do.

How to use it: print it (Ctrl+P or Cmd+P, then "Save as PDF", or print on paper) and take it to the showroom. A spreadsheet version of the tonnage and running-cost worksheets is on your access page. Start with chapter 1: it tells you which machine to look at.

The rules quoted come from official bodies: the Bureau of Energy Efficiency (BEE) for star labels and the 24 °C default setting, the GST Council and CBIC for the tax rate on air conditioners, your State Electricity Regulatory Commission for tariffs, and the Department of Consumer Affairs for complaints. Every chapter names its source. Consumption and price bands are indicative, stated as such, and the method always lets you replace them with the figures on your own label and bill.

Chapter 1: Air cooler, window AC or split: the choice for each room

In India the first question is not the brand. It is the air. An evaporative air cooler cools by evaporating water, so it works well when the air is dry and poorly when the air is already humid. An air conditioner removes heat and moisture with a compressor, and works in both cases, at many times the electricity.

Step 1: what is your summer like?

Your hottest weeksWhat worksWhy
Very hot and dry (much of the north-west and central plains before the monsoon)An air cooler can do much of the work, with cross-ventilationDry air takes up evaporated water easily, so the air leaving the cooler is noticeably cooler
Hot and humid (coasts, the monsoon months almost everywhere)An air conditionerHumid air cannot take much more water: a cooler adds moisture and stickiness instead of cooling
Dry in May, humid from JulyOften both: a cooler before the monsoon, the AC (or its dry mode) afterThe verdict changes with the season, not only with the city

The free city pages on Claude AC give the verdict for 40 Indian cities from their peak temperature and humidity; look up yours before deciding.

Step 2: window or split?

Window ACSplit AC (inverter)
What it needsA window or wall opening of the right sizeA wall bore for the pipes and a place for the outdoor unit
Noise in the roomHigher: the compressor is in the same boxLower: the compressor is outside
EfficiencyMostly fixed speed; fewer high-ISEER modelsInverter models dominate the high-ISEER range
InstallationSimpler, cheaperPipe run, vacuum, outdoor unit stand, core cutting
Good fitRented flats where drilling is not allowed, rooms used a few weeks a yearBedrooms used every night, long seasons, top floors

Step 3: your room list (fill in)

RoomSize (feet × feet)Area (sq ft)Top floor under the roof slab?West or south windows without shade?Hours of use per day in peak monthsCooler, window or split?

Frequently asked questions

What does the pack contain that the free guides do not?

The free guides answer one question each. The pack puts the decisions in the order you meet them and turns them into worksheets: a room list, a tonnage sheet, a model comparison sheet, a bill calculation at your own slab rate with a meter test, a quote checklist, installation and warranty checklists and a backup calculation, plus a spreadsheet.

Why is the price in US dollars?

The pack is sold by a French company through Stripe and charged in US dollars: $19 in total, once. Your bank converts it to rupees at its own rate and may add a foreign-transaction fee. Your card must be enabled for international online payments.

How do I receive the pack?

Right after payment you are taken to your pack page, with the spreadsheet to download. Bookmark it: the link stays valid and always shows the latest version. To keep a copy, print it or save it as a PDF from your browser. Stripe emails you the receipt.

Does it tell me my exact bill?

It gives you the method and the figures to replace with your own: units per hour of each type of machine as indicative bands, how to read your top slab rate on your bill, and a meter test that gives your real figure. Tariffs are set by each state commission and change; the pack never pretends to know yours.

Do you recommend brands or dealers?

No. Claude AC is an independent information publisher: we do not install, sell air conditioners or take commissions. The pack helps you compare what you are offered.

What is the guarantee?

The pack is guaranteed as described: if it does not open or contains an error, we fix it, and if we cannot, we refund you in full (refund policy in the terms of sale). A duplicate payment is always refunded.
