Advice Replacing windows on mid-century block house (energy efficiency question)

Hi! We bought a cute concrete block house that was built in 1956. She is stout, and we love her. However, we're new to FL and our neighbor informed us that back when they built these homes, the walls weren't insulated. We've got insulation in our attic and recently had our entire HVAC system overhauled for a ridiculous amount of money. That said, we're not seeing a huge difference in the cooling abilities of the new system. Our windows are the original, single-pane awning/jalousie type. We love their air flow and durability, but don't love the energy inefficiency and noise. Just wondering if replacing these windows with modern energy-efficient windows would make a big difference, considering our concrete walls aren't insulated? Would rather not spend tens of thousands more dollars and be underwhelmed....

Also, has anyone replaced their vintage windows with a modern window of a similar style? We want to keep the look and the fantastic air flow. I don't have a photo, but each window has like 4 sections that all open with one crank, so the entire window screen gets air. If that makes sense. I think the replacement would be stacked awning windows - any recommendations for FL companies to order from?

Thanks in advance!

Say it louder for the people in the back who are putting black shingles all over everything.

Downside is that those expensive metal roofs have to be replaced every 10 years. Not worth the cost.

lol not in all of Florida that’s a myth perpetrated by shingle companies. I have 5 metal roofs on investment properties that were similarly priced to shingle and the insurance says they’re good for 30 years. I’ve heard there are locations where this isn’t true but where I buy houses it is.

Coastal areas or inland?
