Got AC for the first time this year but I can't get the window kit to fit. On the plus side, our new house is better insulated and we moved to a quieter area so we can have the bedroom window open a bit at night without being disturbed by as many drunk people. It's 22°C in the bedroom at the minute which isn't great but not so bad that the AC needs running, I'll have to figure it out for the summer months though.
