Condensation on windows (new house)

We moved into a new house in KC, MO about a month ago. As part of the heating package (Lennox heat pump with gas furnace back up), the heating contractor installed an Aprilaire (sp?) humidifier (model 600?).

The problem I have is in the master bedroom. We do not have traditional wood slat blinds in that bedroom. The blinds are the honeycomb type so that no light comes through. On these two windows, there is always condensation in the mornings. None of the other windows has any condensation. Could it be these types of blinds do not allow air circulation behind them so that is why there is condensation? Is it possible that there is something wrong with the windows or the way there were installed? I have tried to not have the blinds closed all the way down to the window sill. I have left about a two inch gap at the bottom, but there was still condensation on the windows.

I have also tried to turn down the humidifier down to a lower setting and that did not help either. It currently is set between "6" and "7" on the humidifier control.

TIA

My suggestion to you would be to first go out and purchase a DIGITAL humidity guage.
They are not very expensive and are the only way to know what the humidity level is in your home.

In cold climates a humidity range of 30% to 40% would be what your home should be.

If you maintain a maximum level of 40%, have reasonable ventilation around the windows, and they still sweat, the quality of the windows would be the cause.

Here are some links to home humidity info.

Greg,

Thanks for your reply. Where can I get a humidity gauge?

Do places like Lowes and Home Depot sell them?

Thanks again
