What temp do you set your AC to before you leave the house for work?

69 and 68 or 67 when I go to sleep. During the Winter I like to sleep with window open as well. Sleep much better in the cold.

Mine is set to 24ºC, but leaving your AC while outside is horribly wasteful.

Yep, I can't imagine how hot my house would be with no AC on all day. I leave mine at 81

You can pruchase a programmable or connected thermostat. It doesn't have to be a Nest or something fancy like that. Mine costs about €70 and allows me to set the AC from my phone five minutes before reaching home. It basically pays itself.

Yeah, but then you're hot. The point is to stay cool on hot days. That's what AC is for. If its 105 degrees outside, I'm turning my AC unit to a cool temperature, energy use or cost be damned.
I'm with you. I was just answering about leaving it off vs. turning it hotter when not home. Hotter does save energy, but I'd never shut it off, and when I'm home it's as cool as I want.
That's another good point for just leaving it off. If you keep the AC on, you're forcing it to work through the hottest part of the day, so the energy you spend gets less work done. Programming a long cool-down period right when you get home from work seems more efficient.

But I don't want all my food sitting in 82° and humidity. Better to not let the house get totally stagnant hot imo

We got some real soft cupcakes in this thread. Oh my god it's 90 degrees out, I must set my AC to 60 degrees or sweat might roll down my back. Come on now.
What's the point of even going to work if only to come home and sit around being miserable in the heat? Don't people have jobs to provide a chance for them to better their lives or enjoy their lives more? Well, part of that for me is enjoying sitting around my place playing a game or watching a movie with my family, and I like it to be cool in there. I had enough sweating in AC-less homes while growing up.

No. Because you're causing it to work harder if it has to go from 80 to 70 when you're home. And why would I want to come home to a house that's 80 degrees.

Set mine at 75 and then every hour it goes down a degree from 2-5 before I'm home

Wait, you leave your AC on when you're not home?

How are you not bleeding out your ears with your electricity bill...

its programmed, 82 when we leave for work, 1 hour before we get home it kicks down to 76, at night it kicks down to 72 to have nice sleeping temps. We live in Texas.

In the winter the heater is set to 68 and drops to 64 when we arent home.

Since I'm catsitting right now, I usually set it to 78 or so when I leave, and turn it back down to 75 when I get back. If I am alone, I set it to 82 or so. I live in Florida, and on the top floor of an apartment complex, so I prefer it if my apartment isn't a complete humid hot mess when I get home.

I cry myself to sleep every night over it :(

I come from a place where it regularly hits negative numbers in the winter, so I'm used to hilariously high energy bills in the winter, so for me, the summer, even with the AC on all the time, is still cheap.

In the winter, 300 dollar bills are not unheard of. While in the summer, even with constant AC, I've been barely hitting 100.

Geez, that makes me kinda grateful. Where I'm from we just have two seasons: Dry and Rainy so the temperature at lowest is 25 Celsius and at highest 40 Celsius, so either way you only really 'need' AC in the middle of the day when it's hottest. Leaving your AC on when you're not home would be seen as very, very wasteful down here, though I can definitely understand why you'd need the heat in winter (never experienced winter temperatures myself though)

Electricity here must be more expensive though, leaving my AC on all day everday would kick my bill up to at least $450 USD, seeing as having it on just at night has it around $250...

Not when you live in Louisiana and don't want to come home to a house that's hot as hell. Anyway, I keep mine at 70. I'll be damned if I come home sweating, then have to wait an hour or so for the house to cool down.

My A/C wall units sput out if I leave them on for too long so I turn them off.

When I need heating though I leave the temperature at 65F 24/7.

So set the timer for home-time minus 60m?
 
Why is Canada electricity use so high.
Heating against the cold climate. Also maybe they don't use gas for cooking?
Off.

Completely wasteful. Get some fans if you need cooling while you're out.
Whether that's true depends on how you use it when you're home.

If it's 72 when you're home and you let it go to 78, it's probably more wasteful to cool it down again than to have kept it at 72 (or maybe 74) the whole time.

80. The lowest I ever put it to when I'm home is 76, though. Florida resident here.

I love florida "winters" because it's literally in the low 70's all the time. You can just never run AC and open your windows. Favorite time of year, and there's so much saving on your energy bill.

Bullsh!t.

If I leave my AC running all day my electric bill is over $200. If I turn it on after I get home it's just over a $100.
 
I wanna see the receipts

It all depends on how big your apartment is, what shape it's in, what the delta in temp is, how hot it is outside, etc. It's possible I'm wrong, but it's hard to believe that there isn't a set of variables for which one method is better than the other.

76, then have it set to turn down to 73 an hour before I come home.

Due to the trees that provide shade for mg house, the inside really doesn't get warmer than 75, but the bedrooms upstairs hit 77-78 or on a hot day, but even with the ac on the forced air isn't really that effective and only drops the temp to like 76 on/set for 73. But it does help remove humidity, which is half the battle.

Heat in the winter, A/C in the summer.
It easily gets down to -20C in the winter, and very humid +35C in the summer.

Our houses are basically hermetically sealed because we spend so much of the year doing one or the other. There's about 2 glorious months in each of spring and fall when you can get away without either.

Electricity was super-cheap here through the 70s and 80s, so a lot of homes built then use very inefficient baseboard heating, and don't have gas hookups.
 
Never heard of leaving ac on all day when out at work and i live in Australia and it gets pretty hot where I live. We only use the aircon a few times per year, when the thermometer gets to 27c (80.6) inside the house. Rest of the time just use fan when at home if needed. Hardly use the heater in winter too, just used it for the second time this winter yesterday and only when temp is 17 (62.6) otherwise it's just a waste of electricity. I also have a large (7kw) solar system.

I didn't know people changed it when they left? I have never had a family member or friend do it that I know of.

I keep mine between 69 and 71 at all times.

I'll be sure explain this to my vet when I have to bring my cats in because I was too cheap to leave the AC at a reasonable temp for three days.

Our bill is only like $40-60 more expensive for the four months we use AC and is totally worth the money.

It's like, motherfucker we went from a trailer with no screens on the windows that would get 120F in the summer to a basement apartment with heat only and one window to an apartment with one shitty wall AC that leaked and only cooled the living room to a house with proper central AC. We've served our time.

Lol we complain about global warming and then even liberal gaf leaves their ac on all day because they can't be bothered to wait 10 minutes for their houses to cool down.
 
I mean, if you have pets that's totally understandable. But I can't imagine wasting 8+ hours of electricity JUST so I can not have to deal with a hot home for 20 minutes while the A/C kicks in.

My place is sweltering hot when I get home. So first thing I do is open the windows, turn on the AC in the living room and bedroom. Then go take a shower. By the time I get done with that the bedroom is cooling well.

Living room takes a long time to cool due to the volume of air that needs cooling. But that still doesn't justify 8+ hours of leaving it on. Doesn't that contribute a fuck ton to global warming?

EXACTLY. I mean wtf, lmao. Next thing I'll find out people leave their cars running with the AC on because they don't want to deal with a hot car when they get out of work....

Midlands of South Carolina here. I do 76 during the day, 74 when I am home and 72 at night. Although I forgot to turn it up this morning. Dang it.
 
Well, this thread made me go look into wifi thermostats. It's going to be either honeywell's wifi thermostat or sensi wifi thermostat depending if I have a c wire or not. Will look into how hard it would be to hook up a c wire.

I leave my ac off when I go. It would be pretty cool to come home at the right temperature.

Cause that will totally dehumidify the air...

Obviously we have a huge variety of environments here. People have split level homes, vs ranch, vs apartments. Some have central A/C, while others have window units. There a large cross section of temp and humidity too.

If I left my A/C off during the day, I'd have mold growing wild in the basement. Of course I could run a dehumidifier, but that's not cheap either. It's going to be 90 F where I'm at today, and it's 90 % humidity. It'd take forever for the house to get comfortable after having A/C off all day, and there's more to it than just an acceptable temp when you're home. Instead I have an efficient unit with a multi-stage compressor and I keep the place controlled.

I don't set it. If it's too hot when I get home I just usually set it to a couple degrees (F) cooler than what it says and it does the trick for me. My place is about mid 80s when I get home, so low 80s.
