I think the humidity of the regional climate matters a lot. In NY, near the great lakes, where its pretty humid, most people like it a bit cooler than 78. I keep my air around 74, and addition to that, I keep a window air conditioner going in my bedroom.

In the winter I keep it about 68/69.

 

Western NY averages low 70%, more like 80% in the morning.

 

There is a lot of dew in the morning.

 

It's not only that. Age and body mass can play a part when it comes to comfort levels as well. I live in Western NY too and our home has central air. I prefer to keep my thermostat set at 76 in the summer because in our raised ranch, on the lower level in our "family" area it's always a few degrees cooler and anything colder than that is too cold for me if I'm just sitting at the pc or watching the tube. On the other hand my husband can stand it much colder and is quite comfortable but he outweighs me by about 100 pounds.
In winter however, we keep things at 72 and will turn on a quartz heater if we need it. Go figure but when it's 10 degrees outside, it feels relatively comfy.
As for the dew, we're waiting at the moment for things to dry out so we can mow the lawn but everything has been green all summer.

 

I have no say so with regards to the temp in our house. That's the girlfriends call and it's usually 74 which I'm good with.

 

you're a good B/F

 

The wall.

 

Im like you. I'm happy (chilly at times) at 70, but I'd rather just throw a sweatshirt on. My husband insists on keeping the AC at 73, even now. I feel like I live in a meat locker...and he is the one who bitches about the the bill.

 

I'm happy with the thermostat around 69-70ish, but if i didn't have a toddler and a fiance living with me, i would probably leave the heat off until it was like freezing cold in here. I really prefer things cool. I swear i descended from Antarcticans or something. I like summer if i'm going to do summery things outdoors, but aside from that i want it to get cold again.

 

68° during the day and 64° at night while I'm sleeping. Vaca temp or when I'm out of the house is usually 74°.

 

Reina, why are you heating the house when you're not there? OH! That's your answer for the summer time. Derp.

 

Yes, lol. I don't have a winter usually. I like it cold, though.

 

We always leave the thermostat on set to like 60 in the winter and 78 in the summer if we aren't there. The goal is to keep the wood from warping, humidity not to get too high or low, etc. A bit of cost, but once damage is done, it can't be corrected.

 

Summer....when I am home I usually keep it at 71 or 72 with fans going in every room.

Not home I usually bump it to 74 through the month of May and then up to 76 from June through September.

Winter - I rarely use the heater during the so called winter so my electric bill is next to nothing from about November through April

 

Winter: 69
Summer: nothing unless it's really humid, then 77.

 

It really depends on the temperature outside. I usually like to keep it between 71 and 75. Not too hot, not too cold.
