Condensation on windows

Every morning when I get up the windows have condensation on the much so that I can't see out them! The AC is on inside at 20 degrees Celsius... And most of the windows are vinyl... Is this ok? Is there anything I should do?

Condensation on windows

20 Degrees C ?
I don't think I could stand it that cold.
Do your electricity bill a favour and turn up your thermostat a little. Should help with the condensation, too.

Condensation on windows

The glass is cooler than the dew point outside, causing the condensation on the outside.

Many people make the mistake of thinking the multi-layer, gas filled windows really insulate. - The U value is about the same or not much better than an uninsulated 8" concrete block without the benfits of thermal mass and zero radiant heat transmission.

They are still better than hole in the wall.

Turn up your thermostat. We have ours at 75F 24/7 and still get some condensation. Yesterday, with 96F and 85% humidity, we had condensation all day on the lower level because of the proximity to the grass/soil after a morning 2" rain shower in 15 minutes.
