Putting window tint film on a SW facing Florida room

[olnacl]

I think, from the comments generated, I'll have the pro do the job - after I do my upcoming cat-sitting stint. While they would enjoy the cooler temperatures the film might provide, they'll have to deal with it as they have for the past several years when I've been their temporary caretaker - and I don't even particularly LIKE cats - mostly because they're aloof and I'm allergic to them.

Thanks to all for advice and comments. As always, I can count on the forumites.
