エアコンのない生活なんて考えられないって英語でなんて言うの？

Imagine Life without...(something) Losing something you have grown so used to having... And perhaps have "taken for granted". IE: It was normally there and easily accessible...But now its gone! "You never miss the water ..til the well runs dry" (an old English adage) We might find it very difficult ..."to do without" this essential need.

This is a way to be a little more polite or sensitive about something because many people don't live with air conditioning. I hope that this helps. :)

air conditioning = a machine to make air colder heating = machines which make air warmer (radiators, central heating, oil heaters) If you want to be formal, it is best to use 'cannot' or 'could not', but 'can't' and 'couldn't' are more natural in informal speech

Life without A/C must be horrible This is a very common expression in the U.S. when talking about a/c. This is most popular in very states such as FL, TX, AZ and such. I cant fathom the idea of living with out a/c. In this expression the word "fathom" is used to emphasize how much you would miss and how unconfortable you would feel if you did have a/c in your home or work office.

The two sentences you see provided above are terrific ways to express to your listener that you can't imagine your life without air conditioning. In the first sentence you will notice the word picture. This means to imagine. In the second sentence you will see the word comprehend. This means to understand. Both of these words are appropriate for formal and informal settings.
