Why not consider washing and hanging it out in the evening? And with the help of the condensing unit when you on your air con at night, it speed up the drying process, as good as a dryer.
I handwash my hubby, baby and my clothes and hang it out around 8 pm. By tomorrow's 2 pm, it's dry (actually, it's mostly dry in the morning). I did bring it back inside to hang, scared that it'll rain in the middle of the night, but since I slept around 11 pm, and with the help of the air con or evening wind, so far no problem.
Wah. So smart. Must learn from you and save some $$
I'm not smart, only feel that complaining won't solve the problem so might as well think of alternative ways.
