Reply to comment by Draconicien in Researchers designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. This cooler may lead to an annual energy saving of up to 86.3 MJ/m² or 24 kWh/m² in hot climates by mossadnik

It’s possible to have just the glass replaced with double paned, argon filled, low-e glass without ripping out the entire window. That said it’s a heavy YMMV. Depends on your specific windows and finding a company that will do it. As a general contractor I’ve got a window company that will do it, although they prefer not to and a glass company that don’t mind it.

You may have to call a few places, the big guys won’t do it, they’ll insist you have to replace the whole thing. The smaller mom and pop, or new start up company will be more hungry and willing.

There’s significant liability concerns on their part as the glass isn’t guaranteed to come out clean and you’ll have to know that going into it.

Replacing just the glass is less invasive for you as the home owner, but it may not go back together perfect, so be warned. There’s a lot of factors to weigh out and someone over the Internet won’t be able to answer what would be best or possible for you.
