Prompt
Help me choose a air conditioner. Room or household details: bedroom about 12×14 ft, top floor, west-facing, two people How we will use it: 8–10 hours a night from April to September in North India Budget: ₹35,000–45,000 Give me: 1. The right size or capacity for my case (e.g. AC tonnage or washing-machine kg) and how you worked it out. 2. The main types (e.g. split vs window, inverter vs fixed-speed; front-load vs top-load, fully vs semi-automatic) in a small table: upfront cost band, running cost, space, maintenance, best for. 3. Features worth paying for and features to skip for my usage. 4. How to read the energy label in my country and roughly how star rating affects the electricity bill (show the formula, with my own tariff as a placeholder). 5. Installation, warranty and after-sales questions to ask before buying. Rules: If any detail you need is missing, ask me up to 3 short questions first and wait for my answers. Do not invent prices, model numbers, specs or offers; if you are unsure whether a model or spec is current, say so. Price bands, product models and specifications require dated supplied evidence or current sources you can actually access and cite. Otherwise mark them unknown; do not substitute remembered prices or unsupported bands. Compare delivered prices and terms before purchasing. Offer to compare two specific models I shortlist.

Example output
Actual tested output. The notes used for this result are an example, not a real event. This box is not copied. Replace the notes above with your own before you paste the prompt.
Three questions before a size, type, or cost comparison. I will not invent tonnage, model numbers, price bands, or specs while these are open, and I will not treat remembered prices as current. 1. What is the ceiling height, and about how much of the west wall is window glass? 2. Is there already a window opening for a unit, or space for a split indoor unit and an outdoor unit? 3. What do you pay per unit of electricity? If you do not have the number, say so and the later bill formula will keep your tariff as a placeholder. Noted only, not compared with any model: bedroom about 12 by 14 ft, top floor, west-facing, two people, about 8 to 10 hours a night from April to September in North India, budget ₹35,000-45,000. Price bands and star-label effects need a dated source I can cite. None was supplied. I can compare two specific models after you shortlist them and those sources, or their listings, are available.
