We are planning to replace our almost 45 year old AL frame windows with something double paned and more energy efficient. We are also planning to do the install ourselves assuming that we can save some money that way.

I've got a couple of questions.

We've got a couple of windows that are horizontal sliding windows. Rather than being 3' wide and 6' tall and sliding up and down, they are essentially on their side, 3' tall and 6' wide and slide sideways.

I like the idea of a double hung tilting window that enables you to clean the outside of the window. Is there something similar for a horizontal sliding window. It's especially important as the two windows that we have that slide sideways are both up stairs.

Are there good sources to buy windows without having to pay for installation? I assume that the HD/Lowes route is probably not the best WRT customer service, but maybe I'm wrong.
