my rooms air conditioners thing broke along time ago and the ppl who fix conditioners cant fix it so i was wondering how you can keep your self cool with out it
i already tried openeing the window but only hot air came in...-_-

Answers:
Try making sure most of your lights are off during the day. Lights produce a lot of heat that we usually don't notice. Cooking or baking also produces heat that will add to the temperature inside your home. Also, try using fans inside, but make sure you have you windows closed.. Opening windows will only bring hot air in instead of keep air circulating. Don't open the windows until sundown since it is much cooler at night in the summer. I hope this helps! Good luck!
