I haven't used a/c in years. I don't even use fans in my house now. Temps indoors get up to 85, but I've just accustomed myself to it. But I do live in central NY, so I guess it's not as hot as down south.
Yes...just a *tad* warmer here...it is 85 by 9:30am yesterday in Charlotte, NC. :-)
I have been running with the A/C on almost everyday except when I work late and the temps are below 85. I find that it mostly balances out my FE because I don't drive as angrily and am much more patient to find the "sweet spot" in traffic light timing in my 190 commuter car.
Not using A/C with the wife (originally from Ukraine) and our 2 1/2 year old in the wagon is not even an option. I would like to arrive in the driver's seat, not a bodybag in the back of the car. ;-)
