Double-Hung Window Installation 

The difference between double-hung windows and other types of windows are their two sashes that slide past one another vertically on a hanging track, as opposed to sliding and gliding windows which operate horizontally. This dual-pane style window allows homeowners to get ventilation at both the top and bottom of the windows and clean their panes easily.

Yes, double-hung windows will save you money, eventually paying for themselves in energy savings alone. This is thanks to the insulating layer of nonreactive gas (such as argon or krypton) stored between the dual (or even triple) panes. The multiple layers prevent heat transfer and solar radiation, helping better regulate temperature within the home.

To clean double-hung windows, simply push a button to tilt each pane toward you. Glass cleaner usually does the trick, but for especially stubborn dirt, use baking soda and vinegar. Because of the tilting sashes, you don't have to deal with ladders and dangerous heights when cleaning this type of window. 

It can be difficult to know when to replace your double-hung windows, even if they look okay. One simple test is to see if you have any drafts leaking from your windows or the surrounding frame. During colder months, it is easier to tell if you have drafty windows. If it is warm and hard to tell if your windows are leaking air, try taking a candle and holding it steadily in front of various parts of your window and window frame. If the flame flickers sporadically, you have a draft and it is probably time for new windows. 

Additionally, you would do well to consider upgrading your windows if you have high heating and cooling costs. New modern windows will help you save money on utilities as they provide extra insulation.
