Installing window air conditioner in double hung window?

I just had thermopane double hung windows installed in my house. I don't have central A/C and am wondering how I can install window air conditioning units in my new windows. Thanks!

Installing window air conditioner in double hung window?
most of the time, you can set the unit , o n the window it self





but if you cant do that , you will need 3/4 ply ,and cut out for the unit to sit , maybe use soem type of tape to seal the joint, fro m the wood to the window frame
Reply:alot of the time this is pretty easy. these window units are balanced so they are easy to install. just dont force anything, it will be easier then you think. Goodluck.
Reply:If both windows open....its best to cut a 2X4 the width of the window. Open the windows enough that your A/C will fit in there with the extra space for the 2X4 laying flat. This board needs to be secured in the window on the top part of A/C. The windows will come to rest on top of the boards. Buy some clamps so the windows can't be raised again. Secure the window unit to the top on board and on the bottom of window frame...this will keep someone from pulling your A/C out and stealing it or entering your house at that point.





One other thing...when you secure the board....tilt it down away from house....that way any rain water that gets on it won't run down inside the house.
