AC ठीक नहीं है

You can use this phrase as a complete sentence. Just point at the unit and say it. If you want to be more specific, you can add Mera (My) at the start. For example, Mera AC thik nahi hai. It works perfectly in hotels or rented apartments. You are stating a fact rather than complaining loudly. It is a soft way to ask for help.

Use it when you enter a cafe and feel the heat. Use it when your Uber driver's car feels like a furnace. It is perfect for professional settings too. If you are in a meeting and sweating, this phrase is your best friend. Even when texting a landlord, this is the standard way to report the issue. It is clear, concise, and very effective.

Do not use this if the AC is physically smashed or hanging off the wall. In that case, use kharab hai (it is ruined/broken). Also, do not use it if you just don't like the temperature. If it is too cold, say AC kam kar do (turn down the AC). This phrase specifically implies a technical fault or poor performance. Using it for a perfectly working AC will confuse people.

In India, the AC is not just a machine; it is a status symbol and a survival tool. During the 'Loo' (hot summer winds), a working AC is everything. People often bond over how bad the heat is. Reporting a faulty AC is a common social interaction. It is often the first thing people check when entering a room. Being able to say this shows you understand the local struggle with the heat.

You might hear AC kaam nahi kar raha (AC is not working). Another common one is AC se thandi hawa nahi aa rahi (Cold air isn't coming from the AC). If you are feeling frustrated, you might say AC bekar hai (The AC is useless). However, thik nahi hai remains the most polite and neutral version. It gets the job done without sounding like you are throwing a tantrum.
