Continuing Hlidskjalf 's thread about heating in cold weather... How warm/hot (and humid) does it have to be outside before you turn on the AC? In Pekanbaru or Depok/Jakarta (low elevation deep tropics with typical 30-34C highs and 22-25C lows/dew points) AC is on year round except on "cool", cloudy/rainy days with afternoon highs failing to reach 27C. In Bandung (almost 800m elevation, typical 26-30C highs and 17-21C lows/dew points) family apartment on the 12th floor has an AC unit which is switched on during sunny warm afternoons (28C+) and/or warm humid breezeless nights (20C+ lows and dew points) for sleeping). Although since it's 12th floor it gets warmer than lower floors - inside rarely drops below 24-25C even with 17C lows and windows open. In Lembang (1200-1300m elevation, typical 23-27C highs and 14-18C lows/dew points), AC is not needed except maybe on 27C+ afternoons with clear skies. Overnight lows/dew points in Lembang are rarely higher than 18C so AC is not needed at night, and it can get a bit chilly inside even without AC at night during dry season. But different story in Sukamandi where my dad's relatives live, no AC in my paternal grandma's house even near sea level, close to the north coast of West Java. Fans are used instead, so temps can be up to 32c/90f inside... and anything 27c/80f or cooler inside is on the cool side there... |

Depends on many factors. Different buildings can be very different temperatures inside for the same outdoor conditions, depending on design, direction (south, north facing), etc. I would use AC in whatever outdoor conditions produce indoor temps above 25.

6 beers a night in the Dry Season, 8 a night in the Wet Season = A/C not required.
I sleep pretty well, fully acclimatised. Oh perhaps around Xmas on the odd 28c-30c night I might relent, or entertaining a lady friend but then thats rarer than a 30c night, so simply theoretical, otherwise the AC stays off.
My house is fully airconned in every room, If I have visitors up from down south I run them, otherwise not switched on at all.
32.5c in the living room atm 9.15pm....perfectly comfortable for me, ceiling fans on in every room, no sea breeze tonight.

I like to keep indoor temps between 68-76 so when 80s highs become consistent in June, A/C goes on.

Indoor mean temps above 85 F (29 C). Indoor temps above 90 F (32 C) are fine because they're usually accompanied by indoor morning lows in the mid to upper 70s, so sleeping is never uncomfortable with a fan.

I chose 25-30 C/77-86 F. My place gets quite hot even at moderate temperatures.

Outdoor temps are irrelevant. If it’s above 76F inside during the day or 68F at night the A/C is on.

From personal observation, I would say when HDD(Base temp 18°C) has accumulated more than CDD in the last 5 days.
Not necessarily need a/c on one >30°C day if that week's surrounded by full of <25°C days.

If you don't use A/C in a warm/hot climate, then you're an Übermensch
Although for a serious reply, this one's hard to delimit—if there's even a hard-and-fast point above which I begin to contemplate using the A/C. I've done multiple consecutive days with indoor temp. maxima in the lower 90s and slept in upper 80s temps before (which wasn't uncomfortable with a fan; it helped for me to drink prior to sleeping so I don't wake up thirsty). I know for a fact that indoor temps in the 80s/90s are definitely tolerable, or even comfortable, especially given decent cross-ventilation and I certainly wouldn't use the A/C in these temperatures. Temps into the lower 100s are likely tolerable for me during the day, but I have limited experience with temps indoors above the mid-90s.

I use the fan a lot more than AC. But I usually turn on the AC when it gets over 33 C or so with 24+ C dewpoints. At night I often wake up shivering if I run AC, but I prefer to have it on if the lows are 27+ C.

I don't have A/C at all - waste of money, and unnecessary for my superior intellectual climate

I never had central A/C until this summer, but we turned it on during periods of indoor temps of 75F+ which usually corresponded more to lows than highs. When lows were consistently in the low to mid 60s or so there wasn't enough cool down at night to keep it comfortable. I'd say we used it about 7-8 weeks this summer - more sporadically than consistently though

Where I currently live, it generally has to be sunny and above 28 C for more than a couple hours during the day for indoor temperatures to exceed 26-27 C. Dew points are generally below 15-16 C in the summer, and high temperatures are usually between 24-32 C. Hot indoor temperatures above 26-27 C can almost always be fixed by opening the windows at night since nights generally cool down to below 18 C and outdoor dew points are very rarely above 18 C.

If I lived by myself I would never use it. The only time I would be tempted is if the temperature got into the high 90s F, but even then, not worth it.

I don't need A/C in SLO or Seattle. Maybe >22c means is the point where I would want A/C, though it depends on the climate and building construction.

Based on experiences, it depends on how long I was subjected to the warmth for.. so if I go somewhere warm, initially I'll feel too hot to sleep at indoor temps of 25°C or so, but acclimation will follow and I could eventually tolerate perhaps up to 30-31°C, but no more.
