Tom Kraeutler asks,
I would like to install air conditioning on the 1st floor of my 2 story home. I have casement style windows that swing out so I can’t install a window unit. I could install central air, but I don’t use the 2nd floor of the house. The windows are 10 yr old Anderson. Should I replace 1 window with a double hung window so I can fit in an air conditioner or should I opt for central air?
