Best Windows for Florida Heat? Seeking Advice & Experiences (Tampa Bay Area)

Hi everyone, I'm a homeowner in the Tampa Bay area looking to upgrade my old windows to more energy-efficient ones. My house was built in 1985 and still has the original single-pane aluminum frame windows. With the Florida heat (and humidity), my A/C runs a lot. I'm hoping new windows will cut down the electricity bills and improve comfort. I've been researching and there are so many options and terms: Low-E coatings, argon gas fills, vinyl vs aluminum vs fiberglass frames, impact-resistant glass or not... it's a bit overwhelming. Some windows have different Low-E (low emissivity) coatings - I see things like double Low-E or even triple-layer Low-E glass. Also, gas fills like argon between the panes for insulation. I'm not sure what combination is best for our hot climate. For example, is triple-pane overkill here? How important is the argon gas? Are vinyl frames durable enough for Florida sun, or should I consider other materials? I'd love to hear from anyone in Florida (especially Tampa Bay) who replaced their windows for energy efficiency. What did you choose (Low-E type, gas fill, frame material, brands)? Did you notice a big difference in your energy bills or indoor comfort afterward? So far, I've gotten quotes from a couple of local companies (Karoly Windows and ProTech Windoors). They both offer double-pane windows with Low-E coatings and argon gas. One quote is for vinyl frames, the other for aluminum frames with a thermal break. The cost is significant, so I want to make the right choice. Any personal experiences, recommendations, or lessons learned would be greatly appreciated! Thanks in advance!

Time to start saving up for those new windows... but at least now I know what to look for. 🙂

Aww, thanks @charles_sage @leadership641 @saraha70. I'm really glad my question turned into something helpful for others too. Couldn't have done it without all these amazing people sharing their knowledge.
I'll keep monitoring the thread, and if any new questions pop up down the line (or if I encounter anything unexpected with my new windows as time goes on), I'll chime in.

Cheers to more comfortable, energy-efficient homes for all of us in Tampa Bay!
