78.

I used to do 76, but as long as you keep the humidity down with it is the main thing.

76 used to be my feel good zone, I like 78, 80 isn't even bad as long as the humidity is lowered.

And when we replaced it a couple of years ago I did buy one over sized for the house as far as tonnage, it's working much better than the old outdated system.

If I wanted to live in 68 degrees most of the time I never would have moved to FL 25 years ago 😛

I keep the thermostat around 76F. Sometimes I'll set it to 77F when I go to bed. If I didn't have ceiling fans, I'd probably have it set much cooler.

Yea, I also run 2 large fans on medium speeds in my living room and bedroom continuously, I should have added that I guess.
 
When it's 100F outside, I wonder how much money you actually save keeping it at 78 instead of a more comfortable 74 or 72.
 
What is the correlation between AC temp and the bill? I have read or heard that every 1 F below a standard temperature changes the bill by x %.
 
I need to redo my A/C system as the intake and ducting were done in the wrong sizing by the previous homeowner.

I keep it at 74 which is about as cool as it can get my house on 90+ days.

Ideally, 68 is ideal for couples sharing a bed.

There is that too, I have 3 large ceiling fans just running on low to keep air moving around the house.

Its been set to 68-69ºF at the second floor thermostat when it was well into the mid-90's last week. Using a small (not tiny) fan on low to mitigate some colder spot to the room this computer is in. I'm fat and from NE and living in Atlanta has its drawbacks.

The wife hangs out on the first floor and keeps the thermostat set to 74-75ºF during these same warm periods, but I lower it to 72ºF when I join her. The basement is at 75-76ºF when not being used and I drop it to 72ºF when I go down there. Wife is from the South and lives in fear of being in snow.

74. Phoenix AZ here. AC runs almost 24/7 in the summer with monthly bills around $350/mo. It's worth it though, never understood sacrificing comfort to save a little dough.

I imagine it gets pretty brutal when the temperature outside is pushing 40 every day, even though it's a dryer environment.

When I was in Cuba during the winter, it was a 30c dry heat pretty much every day. Felt perfectly comfortable for me. If that were here, it would be sweltering. I used to keep the windows open all summer but the traffic noise now makes it impossible to sleep.
 
Central Fl. here, 76F on the thermostat, but actual room temp is 78-79F
Most of you might want to check the real air temp in the room, thermostats aren't known for being truly accurate. 😉

Oh, and I love those energy experts that say fans aren't good for cooling, they cool the people but not the room.
WTF, do they think we are trying to cool, I relly don't care if the sofa and drapes are happy??

Most newer thermostats have thermocouples, which are way more accurate than older thermistors.
 
My place is three levels, with poor air circulation on the top floor and no attic fan. I need to keep the thermostat on the bottom floor at 73 to have the top floor, with the bedrooms, at about 78 or 79. It's seldom, though, that I need to run the A/C at night. Just open up all the windows and doors and the place will get down to the mid or low 60s most nights. Close her back up in the morning and it doesn't get warm in the house until mid-afternoon.

80. It's actually comfortable. Your body adjusts to it. Probably too warm for most but it feels great to me. I use ceiling fans too. It's usually 95 to 105 outside so the difference in running 80 vs 72 is probably a couple hundred dollars a month minimum. Also like I said I feel comfortable.
Also I'm not morbidly obese so I don't need it frigid to keep myself from overheating.

~72-74F here, at least during the summer. I don't really care much for humidity, and I live less than half a mile from a pretty large lake.

In the winter, when it's much drier, I prefer it to be around 77F.

77-78, we have a brick house with no shade and I've found those to be the best AC temp to compensate for the heat from the bricks radiating in as well as the humidity.
