“If you don’t like the weather, just wait five minutes, it’ll change.” --Ohio weather proverb
That being said, I have turned on my AC as early as April 12th (I checked my Facebook Messenger app to confirm).
I just turned on my AC. The thermostat said 78F, but that hallway was the coolest part of the house. I don’t actually know how warm it was in the kitchen and bedroom, but it was muggy and sticky and icky, and I thought, “this is why I have AC”.
My thermostat seems to be broken. I had to fiddle with it quite a bet to make it come on. It’s a mechanical switch that’s gotten fussy – it went on when I jiggled it at a point between “off” and “cool”. I guess I need to buy a new thermostat.
No air conditioning at 11,200 feet in the central Colorado Rockies. We rarely get over 80 degrees. Had a couple of inches of snow today.
The closest town to me, Alma Colorado at a paltry 10,500 feet has an average high in July of 63.9F.
Bring a sweater 
I broke down late this afternoon, it’s high 80s and just not comfortable. Tomorrow is supposed to be just as bad if not worse, but then it should just be low to mid 70s for a bit. I’m hoping to get through these two days and then turn it off and open windows.
It’s been 90 the last couple of days in the DC area, but due to the amount of shade of takes a while for the house to warm up. It cools down Saturday, so it’ll be a while before AC comes on. For me, it’s when it gets close to 80 inside. For Ms. P, never.
On the shore of Lake Michigan, with snow on the ground still in some places, and temps under 50F daytime, a/c doesn’t sound inviting here. I have to drive 5 miles inland where it was 80F the other day if I want to get warm. Lake Michigan is a powerful force for natural air-conditioning.
This time of year, I have to wear a coat when I leave the house, then strip down to a T-shirt when I get to town, and put the coat on again when I return.
Turned on a/c yesterday. Outside temp was 90 and inside hit 80. Set to 77.
I held out until yesterday afternoon. It was 80 inside the house, and when a breeze that was distinctly hotter than that wafted in, I started shutting the windows and turned the AC on.
After our windows being sealed all winter, I wouldn’t close them if a neighbor decided to burn tires.
It was 92° in our yard yesterday and 84° in the house at 10PM, so we turned the air on when we went to bed.
This is in St. Mary’s County, MD - it’s not supposed to be this hot this soon. Two weeks ago, we were still burning pellets in the stove.
11-two? How do you breathe? I once visited Alpine Tunnel (train nut) at 11,510 and when I took three quick steps my vision dimmed and narrowed.
Ya get used to it. Well most people do. A number of my guests do get altitude sickness. I keep 02 at the house.
I caved; 88 today and only 75 overnight. Not cool enough for sleeping and tomorrow is shaping up to be 90.
98 here today, house at 72 with AC. But to be honest, since it’s a heat pump it’s always ready to cool if needed and ran in cooling mode for 9 hours in March.
And a 24 SEER system, so I can afford to run at 72 in these conditions. Painfully expensive up-front cost, but I am enjoying it now.
