How often do you use your air conditioner in Vietnam?

November has arrived and for me at home, this usually means I can stop having my air conditioner run throughout the night.  Since returning from the US last January, my air conditioner at home is on all the time.  Granted for about 6 months I did not have a window anymore so I was left no choice to have it on to help bring some fresh air into the room.  I am out of that room now so I can again have my aircon turn off automatically between 2:00-3:00 AM.

When I lived in the Phu Nhuan District, I never turned on my air conditioner until between 7-9 PM and turned it off at 2 AM to help save electricity.  I never ran it more then 6 hours a day.  When I first moved to Vietnam in 2004, I only used the aircon for about 2 hours a day.  Several months later I was in District 5 and again only used it for about 2 hours per day.  I did start using it at night after I burned my arm in 2005 but again, I kept it on for roughly 6 hours per day.

I was a heavy fan user during this time.

Since I moved to District 1 last year, I have started to us the aircon nearly all day.  Yeah, it helps that my electricity is included with my monthly rent which is why I am more inclined to use the aircon all the time when I am home.  I think I am not averaging about 12 hours of aircon use per day which means when I am home, it is on.  I will try to bring it down to 6-8 hours per day.

Unfortunately, even with my fans, I cannot live without the cool air.  I am a Seattle guy so I guess I will always need some cool air to sleep with.

So how many hours a day are you using your air conditioner at home?
