Ever thought about running a swamp cooler in house during the day? Never heard of one until I moved out to AZ, definitely helps keep the house cool as well as keeping the electric bill from being astronomical. I keep the SC in the warmest part of the house while the A/C is on during the day.
I keep mine around 65 in the winter, my house doesn’t hold it in well and it just runs constantly and costs a fortune. Run space heaters here and there
I spend many of my days outside and 76+ doesn't feel comfortable to me. I like the cold. I'll wear shorts in the 40-50s.
Might help but as J.Brant mentioned, humid climate might not make it as useful. Forgot you're down in FL.
Side note: I have an HVAC guy I know that told me that programming your thermostat to turn down AC/heat when you are away at work only saves you energy in the Spring/Fall. Summer and winter it ends up costing you more to reheat or recool the house. Better to just leave it at a constant temp.
This true, and has been the biggest source of fights in my life. Heating and cooling degree days are a thing.
