Will warm water shorten the life span of a goldfish?

My tank is 75 gallons, it has two Marineland Emperor 400 filters, and some airstones to help with the oxygen levels. My goldfish seems very active and happy, so I am not going to worry about the temperature right now.
Thank you for replying
 
I too live in Central FL, My tank stays about 78-80... of course my AC is on all summer but my point is that if your tank is 80 and does not get much hotter than that, you should be fine. I have two canisters (Fluval 404 and a Rena XP3 and a 12 inch air stone which they love to play in.
