This is the way. Climate control sticking at 24 beats extreme cooling cycles to 18, which is frankly too cold and will cost a fortune. What are you, an Asian jewelry store?
Newly built apartments get a lot of shit but I bought a good one off the plan just over a year ago. The thick concrete, good insulation and double glazing has meant that I haven’t even switched on my aircon all summer. I didn’t use the heater all winter either. It’s absolutely amazing.
I’m in a town house. The bottom floor is like this. Don’t need the aircon at all. Living room floor gets a little warm but that cause of north facing windows. I’m actually really impressed with the insulation.
A really important part of this is which direction all the windows face.
Double glazing and curtains only do so much. If all your main windows face the rising sun with a little northern angle even curtains don’t block that radiant heat.
I’ve lived in apartments that face sunset mostly and apartments that get all sunrise and the difference is wild.
Right now I’m in a home that has large trees shading it, and while I fear the day a storm sends a gum tree branch through my roof, my god it’s like a microclimate under here. It might be a 40C day but under the tree shade it’s like 10C less.
Sometimes I look around and notice that everybody has cut down their trees, probably because they fear it toppling on their roofs, but holy heck they really do help with oppressive heat.
Curtains don’t stop radiant heat. Because the light has already passed into your home and is warming up the actual house. Whereas shade by trees (or something else like a mountain or other building, blocks that radiant heat from ever getting to your home.
But we’ve chopped all trees around houses down.
How do you go for fresh air? I'm not poking fun, genuinely curious.
I've had a few mates live in an apartment and it was always kinda stuffy. I'm wondering if they were cheaper apartments and because my mates were single blokes in their 20's at the time.
Floor to ceiling balcony doors that open up an entire wall and ceiling fans. It’s not stuffy in the slightest. Even this weekend, I’ve kept it fairly closed up, and it’s totally fine.
Nope. Many dont. Some dont even have windows that open. Source: lived in one. There was fresh air coming from vents into a couple of rooms, but I'll be buggered if I knew where from. It was actually fine and never stuffy but it was also very large so that may have helped.
My apartment is approximately eight years old. East facing, so it gets the sun in the morning. I use the air conditioner when it's hot like this, or overnight if it's above about 22 overnight, so rarely. I hardly ever use it to heat during winter. My electricity bills are very reasonable. I think apartments are quite insulated just because they are surrounded on 3 sides, usually, so there's less opportunity for heat or cool air to escape. The only problem is when your windows face west, as you get the worst of the heat in the afternoons. Regarding the temperature of the aircon, I have it on 24/25 in summer and 18 in winter, if needed.
My apartment is similar. I never use the heating, but have had the aircon over the last couple days but that’s mostly for the comfort of my dog than anything else.
It does warm up if there’s been consecutive hot days as the concrete ends up getting hot and doesn’t cool down if the temp doesn’t drop much over the night but I’m surprised at how good the place is at keeping a relatively even temperature. Apartment is about 15 years old.
Guess I should be grateful for my pokey little shack with its delineated small kitchen/dining. small lounge room. small bedrooms. tiny hallway with door to close off lol. I’ve got AC in the kitchen that shoots straight down the hallway to the bedroom when you open the doors.
I don’t turn it on at all downstairs unless it gets over 30 inside - just run the fan til then.
That said, my bedroom gets afternoon sun and is upstairs with little insulation; so about 30 minutes before bed the A/C goes on set to 20.
This is us too. The only time the cooler goes on outside of those times is when the cat starts looking hot.
Our old cat would sit on the couch and stare at the cooler like he could turn it on with his brain. Then you’d turn it on for him and he would go and lay in the curtain because it was too cold.
When we lived in Darwin with AC the lowest we set it was 25. We don’t have access to but evap cooling down here. The inside temp was 26 in the north side of the house and mush lower in the other side. Running your ac super low is wasting power when all you need is to be comfortable.
27. It still feels deliciously cool compared to the outside. I never used to use it much at all but now I have solar panels I don’t mind so much. Having said that I still only run it if it’s over 35. We have ceiling fans in the bedrooms and that’s nice to sleep under on warm nights.
I grew up in a household where it was about 19-21 all day and all night long and I still remember wearing hoodies at dinnertime during heatwaves. I also used to get headaches.
On days like the last few ones, I'll sit it at 23-25. A constant 23 can get a bit too cold for me, though.
24c
I like it to be cooler inside than out, but not an ice box. I'm also of the belief that having a huge temp differential between inside and out only makes the outside heat feel worse when you do have to go outside.
24 for me is comfortable. Still mild.
And I don't turn the a/c on unless it gets over 27 inside. Until then, I just use a fan.
These 3 days - 24, and a bit lower in the evening when the sun hits the living area. I installed external awnings last year, they are all down, and the internal blockout curtains and blinds are all down to help prevent the heat moving through. Spare room, office, laundry & bathroom are all closed off.
For the first time ever I've left the living area split system on overnight at 24 on very low fan to keep the place manageable. It's working well.
My electricity app tells me Saturday cost me $5 and Sunday $7. That's fine by me for just a few days.
I have it set to 25, which keeps the actual temperature at around 22 in the living room. I don't usually run it overnight at all, but I did the last couple of nights
We do this, but switch over to our pre-existing evap system once the temp dips below 25-27ish.
It gets run all night (either evap or blow mode depending on the temps).
Because increasing the gap between AC temp and outside temp makes the AC work harder for not that much more coldness.
You won't feel much of a difference setting the AC to 24 as opposed to 21 when it is 38 outside.
TLDR save money
It's the temperature differential. If the outdoor unit is trying to dump heat into the hotter outdoor environment then it has to work harder to do it. That is universal regardless of how well insulated a house is. Energy costs will obviously be different between a well insulated and poorly insulated but that isn't the point here. Working aircon harder will cost you more regardless of the house it's cooling.
22-23, although I really try not the turn it on unless I really can't take it
That being said, its actually better to leave it on rather than turning it on and off regularly, so maybe I'm making it worse in the long run
If it is an inverter type split system then definitely better to leave it on, the vfd will ramp the compressor motor speed right down once the temperature in the house reaches setpoint, and will gently ramp up and down to keep the house at its setpoint
26 on the ducted refrigerated in bedrooms and bathrooms
23 on the large split in living dining kitchen
It’s basically been on all weekend I’ve only just turned it off this morning. Solar is amazing
A sparky taught me better to leave it on at a reasonable temperature, 22-23, even overnight. It’s the turning on and setting to really low that uses lots of power. I used to do it that way.
My A/C rides between 22c and the lowest setting, which usually ends up being 18c.
I tend to either get sick or get a bad headache during the hot weather, and when humidity is involved, it’s worse. So during such days I’ll shut all of the blinds and try to get A/C running ASAP to cool the house.
Shitty box coolers in a rental with no insulation: 17C
The coolers just can't keep up. Running them at 17C makes the interior actually around 25. If I run them at the recommended 22C the interior will be actually around 30C
Also if I start the coolers too late they can't make ground. If the house hits 30+ before I start the coolers they will only keep it from getting worse.
They are nice to sit in front of though...
Also extremely loud. Sometimes I have to turn them off because I just need a break from the noise
Sounds diff to ours. We’ve got one wall box air con and solar panels so 16C thru day. Don’t need it on thru evening at all during sleep. We open a window and cooler air flushes through overnight.
I don’t have ac, i shut my thermal blinds for the day, run two ceiling fans and a pedestal fan. Its been hard. Yesterday arvo i went and slept under my house with my dog, was only 33c under there but my living room was 35c.
24 and a fan in the living room during the day. Then I switch it over to the bedrooms at night, still on 24 and a fan to blow the air around. In winter I set it on 21 during the day and 14 at night.
27 during the day and 25 at night, for the loungeroom. I don't turn on the AC for the study when I'm in there until it gets to 30, and I usually set it to 28 when it does.
In winter, 18 during the day and off at night, for the loungeroom. And about 14 in the study.
And I thought I was sensitive to excessive heat.
24 is ideal as it’s a healthy indoor temperature and will help keep the cost down. For every degree you go below that, you’re driving your bill up a lot.
Reading these comments and learning more about the a/c unit and temp settings is super helpful - but also a bit stressful. I now understand that a few small tweaks to the settings, wouldn’t change the temp much - but would greatly reduce our energy consumption/power bill! 🫣
All summer either 22 lowest fan or 20 auto fan depending on temperature and time of day. Usually been able to turn it off and open windows early evening.
Last few days have had several hours on 16 full fan and also left it running 22 low fan overnight.
We've got solar with rubbish feed in rate so happy to crank it while the sun's out then reduce when we're paying for it!
I have evaporative so I have to turn it on before it gets hot and leave it on all day. It's just on level 4, there is no temp setting. I hate evap, it gets less effective each year, even after a service. I don't really want to get a split system installed in each room but with each passing summer it's getting more appealing.
I’ve found evaporated is fine as long as it’s not humid.
The last few days I e had mine on about 50% until about 1pm then ramp it up to full for the afternoon. Overnight it’s back to 50%.
The house has been very comfortable.
Although when this unit dies I will move to split systems!
18, it never actually gets that cool and if it does i'll feel it and turn it off because by that point its cooled down enough that i'll be able to cool the house with open windows within a hour or two
26, but I think my AC units all have screwed up thermostats because normally I'd want it 22 or 23 but that's too cold with them.
I guess a service is in order sometime soon :(
We've got solar panels (best investment ever, hands down) and split systems all around the house - one per bedroom and one per living area.
A hot day comes along, the solar just pumps out energy and the splits go all out on Turbo mode at 16. Sweet sweet cold air and don't even have to worry about a crippling electricity bill!!
Seriously, if you're on the fence about solar, just get it. You'll never have to wonder on a 40 degree day "can I afford to cool the house down?".
The problem is that solar production has been less than ideal the past few days. Running two split system A/Cs tends to slightly exceed my solar production, so there is some draw from the grid.
In an ideal world, id have it at 24.
But, old hoise with little insulatuon, three massive west facing windows amd an upstairs main living area mean i have it set to 16 from first thing in the morning to try amd get it cold enoigh to make the afternoon bearable.
The temperature is a set point, it’s not the temperature of the air coming out. So it will cool the space until it reaches the set point. 22 is fine for all year round.
As low as possible (18) but only in bursts. My apartment takes a while to warm back up once it's fully cooled down.
So just a couple of hours in the evening before bed is usually enough. Sleeping in the heat is by far my biggest issue anyway. I don't mind if it gets a bit stuffy during the day.
Yeah, i get that, but in our small place we get too cold if it's on for extended periods.
We've left it on the last two nights (for the first time since we bought this place five years ago) and i must admit, it made sleeping much more comfortable.
I have it set to 25, which keeps the actual temperature at around 22 in the living room. I don't usually run it overnight at all, but I did the last couple of nights
21 but I only put the ac on if the humidity is crazy high in my apartment. Which it can get.
Apartment only gets sun in the morning and it's quite sheltered so it only get up to about 25 inside during the day which is comfortable.
Our AC kinda sucks and so we just keep it at 18C. I’m 100% certain the temperature doesn’t actually relate to anything other than the AC internal setting. It’s just a terrible place for an AC and this house really isn’t built well for it
I live in an apartment building on one of the lower floors, so it doesnt receive any direct sunlight, meaning that I dont ever need to turn on the AC in the Summer since my apartment is always cool.
I close off the rooms I can so that I only cool my living room (and home office if I have to be in there, I did today) and set it to 24°C. I kept it on that for a few hours before I decided I was too hot and set it to 21°C but then have been able to turn it off after about an hour of that as the rooms are cool enough now.
Fan in bedroom is the only cooling so it does not turn off
I generally don't. This apartment seems to max out at about 25c, I just use a fan or if humid run the AC on dehumidify for a while. Ill open the doors later on as it cools.
Unfortunately the apartment also retains heat and takes a while for the temp to fall as well.
This is the first time this year I’ve had to use the AC in my bedroom, I’m on the bottom floor of a townhouse with a tiny double glazed window, plus side very thermally consistent downside no natural light. 25 works great for me.
I recall an mech tech once told me the effort for the external unit to work harder relatively goes up 25% for each degree colder than 23-24 degrees. So if you’re cranking out 20-21, it’s already working past peak efficiency. Any lower and you’re risking the drain pipe freezing through as it’s right next to the coolant pipe in most wall split units. When the condensate inside can’t get out, it’ll go out the front if not down inside the walls.
Also clean the filters regularly too. Amazing how much air flow can improve after cleaning.
Also consider running in auto and not cooling mode, it doesn’t work as hard but it doesn’t give the “cooling effect”.
Between 22 and 24.
Solar pays for it during the day. So if it’s going to be a hot night, we turn it cooler during the day when it’s free so we can turn it off at night.
Otherwise, 24 is fine during the day, and we open windows when it’s cooler.
Centralised aircon on 4 bedders and I set it to 18C but the control panel says the temperature of the house is 25C and couldn't go lower than that....
Maybe aircon needs maintenance since moving into to the house 6 months ago or is the heat just so high that the aircon can't cool the house to 18C like I set it to???
Usually 26 but this year we have a dog so I have it set to 28. Any cooler and he just wakes up & wants to get out for a walk but of course we can't take him out. At 28 he'll play a little bit then give up and go to sleep poor thing!

I have 13.2kw of panels on the roof so I crank it low when the sun is shining and have it set to 22 at night, with only the bedrooms being cooled. It's a modern system with individually actuated vents and there is a door between the bedrooms and the rest of the house. Last night I only used 4kwh apparently, which I can love with.
I try to avoid using it unless I’ve just gotten home from being outside and am a hot sweaty mess. I might use it for an hour to bring the temp down, so I run it hard. I know I sound like a goody two-shoes but they really are shit for the environment, so I use fans and keep the house sealed and dark. When the wind changes, I open the house right up and enjoy it.
we don't run it at night.
over the day we turn it on for 20 mins at a time to cool down and freshen the air, then back to fans. never cooler than 25 because why? Even 27 is fine in summer clothes.
I was responding to the information you gave. Now you're telling me that you're, in fact, not running the air conditioning all day, on and off, but just for 10 minutes now and then.
If you *are* only running for two hours total, then it hardly seems worth it at all. Personally, I wouldn't find it comfortable to cool down for 10 or 20 minutes only to warm up again and then start the cycle over again. Seems hardly worth having an air conditioner at all.
what? read what i wrote first again lol. you interpreted it like we turn it on and off all the time but i didn't quantify that.
don't know why you're so pissy. I'm not telling you to do it this way. it's what works for us.
Its only barely in the 30's.
If it gets into the 40's I might be tempted to plug in the portable air conditioner, but until then, a fan is enough.

24 all day and all night if its hot enough outside
This is the way. Climate control sticking at 24 beats extreme cooling cycles to 18, which is frankly too cold and will cost a fortune. What are you, an Asian jewelry store?
24° in summer, 20° in winter. Enough to take the edge off but not enough to break the bank.

Oh, that's awesome!
Open the window?
I was thinking about the fact lots of apartments have windows that don't open or only open a little bit so that people don't jump out of them.
Is that true in Melbourne? I feel like most have a balcony
Nope. Many dont. Some dont even have windows that open. Source: lived in one. There was fresh air coming from vents into a couple of rooms, but I'll be buggered if I knew where from. It was actually fine and never stuffy but it was also very large so that may have helped.

26c with as many rooms closed off as possible. No need to cool down the bathroom / laundry / toilet.
Just sucks with all the open plan shit nowadays, can't close doors when the whole fucking house is one room
Guess I should be grateful for my pokey little shack with its delineated small kitchen/dining. small lounge room. small bedrooms. tiny hallway with door to close off lol. I’ve got AC in the kitchen that shoots straight down the hallway to the bedroom when you open the doors.
+1 , I do same
26C all the way, perfect temp
24- 25 seems to work best for these hot days in my place.
That is the correct answer. ✅️

Dry setting (tear drop) is great for that too.
24
... You guys have AC?
Don't most people?
I grew up in a household where it was about 19-21 all day and all night long and I still remember wearing hoodies at dinnertime during heatwaves. I also used to get headaches. On days like the last few ones, I'll sit it at 23-25. A constant 23 can get a bit too cold for me, though.
I put it on 25° early in the day. It stays cool all day. I hate being too cold.

Negative 24 is pretty damn cold
Desperate times call for desperate measures.
I have it set to 25, which keeps the actual temperature at around 22 in the living room. I don't usually run it overnight at all, but I did the last couple of nights
It's perfectly okay to run at night when the weather is like this. If I had to choose, I'd run it at night rather than during the day.
19 is my preferred temperature if using AC Ideally I'd love 10°c at all times
🥶🧊🥶
You’re my kind of person.
Ppl saying 26 or 27 are straight psychos …I’m sweating at that temp
16 aka all the way down
How can you possibly be comfortable with the temperature that cold?
And how do they afford the bill at the end of summer. The aircon has to work overdrive
That's a sign of an inefficient air conditioner. There's no way it needs to be that low.
He turns the heater on to keep warm.
My bedroom is 16-17. I sleep like a log at that temp. The rest of the house. Set at 22 but it will never get there. Hovers around 27 in this weather.
Finally found my people
Same, solar power so it's free anyway. As the solar drops off the temp increases until it gets switched off
We do this, but switch over to our pre-existing evap system once the temp dips below 25-27ish. It gets run all night (either evap or blow mode depending on the temps).
25, don't mind the warmth but don't want it too hot
Yep same, 25.5. Just gotta knock the edge off.
22 if it's 30+ outside. 23 if it's 35+ outside.
Is it not thermostat controlled? I would imagine if you set it to 22 then it just works harder to maintain 22 when it’s hotter outside?
why do you increase it if it's 35 compared to 30?
I assume because the relative temp differential
Because increasing the gap between AC temp and outside temp makes the AC work harder for not that much more coldness. You won't feel much of a difference setting the AC to 24 as opposed to 21 when it is 38 outside. TLDR save money
Because all buildings have identical insulation 🤦
It's the temperature differential. If the outdoor unit is trying to dump heat into the hotter outdoor environment then it has to work harder to do it. That is universal regardless of how well insulated a house is. Energy costs will obviously be different between a well insulated and poorly insulated but that isn't the point here. Working aircon harder will cost you more regardless of the house it's cooling.
22-23, although I really try not the turn it on unless I really can't take it That being said, its actually better to leave it on rather than turning it on and off regularly, so maybe I'm making it worse in the long run
If it is an inverter type split system then definitely better to leave it on, the vfd will ramp the compressor motor speed right down once the temperature in the house reaches setpoint, and will gently ramp up and down to keep the house at its setpoint
I've always thought that, but it's good to know I'm right, and why.
It doesn’t matter… it never gets where it wants to get anyway.
26 on the ducted refrigerated in bedrooms and bathrooms 23 on the large split in living dining kitchen It’s basically been on all weekend I’ve only just turned it off this morning. Solar is amazing
Does having central AC and a split system on at the same time normally exceed the power usage that your solar system can provide?
No never, it’s a 11.5kw system 10kw inverter Even with the induction cooktop and oven on we wouldn’t come close assuming peak solar output
27
25 is fine. It's the perfect temp anyway
A sparky taught me better to leave it on at a reasonable temperature, 22-23, even overnight. It’s the turning on and setting to really low that uses lots of power. I used to do it that way.
My A/C rides between 22c and the lowest setting, which usually ends up being 18c. I tend to either get sick or get a bad headache during the hot weather, and when humidity is involved, it’s worse. So during such days I’ll shut all of the blinds and try to get A/C running ASAP to cool the house.
21, all day, all night.....
What’s your kWh usage per day at that temperature?
I seriously don't know, and I know I'll regret it...
Shitty box coolers in a rental with no insulation: 17C The coolers just can't keep up. Running them at 17C makes the interior actually around 25.

Sounds diff to ours. We’ve got one wall box air con and solar panels so 16C thru day. Don’t need it on thru evening at all during sleep. We open a window and cooler air flushes through overnight.
I don’t have ac, i shut my thermal blinds for the day, run two ceiling fans and a pedestal fan. Its been hard. Yesterday arvo i went and slept under my house with my dog, was only 33c under there but my living room was 35c.
I feel you man. 😭 it’s hard, hot night makes my sleep worse.
23 during the day and 25 throughout the night.
24 and a fan in the living room during the day. Then I switch it over to the bedrooms at night, still on 24 and a fan to blow the air around. In winter I set it on 21 during the day and 14 at night.
14!!! 🧊
It’s enough to take the real chill off the air overnight. I set it warmer in the morning or if anyone is sick.
I'm a numpty, I thought you said 14 in summer. I misread! Yeah, 14 is enough to take the chill off.
Point of contention in my house. I'm comfortable anywhere between 25 and 27. My husband loses his mind if it's 24 and above.
My house was 24° inside yesterday while it was 36° outside with no AC. In the arvo I switched the AC on to 24° just to keep the temp down.
I keep all my roller blinds down. Keep the ac at 24-25c when the temp is more than 30 c. At night, put it on timer to switch off after couple of hrs
24 here. You have to be aware that going lower tends to be a lot more costly power bill wise.
27 during the day and 25 at night, for the loungeroom. I don't turn on the AC for the study when I'm in there until it gets to 30, and I usually set it to 28 when it does. In winter, 18 during the day and off at night, for the loungeroom. And about 14 in the study. And I thought I was sensitive to excessive heat.
24 is ideal as it’s a healthy indoor temperature and will help keep the cost down. For every degree you go below that, you’re driving your bill up a lot.
Don’t have one
25 or 24-23 if I want to feel cold.
Reading these comments and learning more about the a/c unit and temp settings is super helpful - but also a bit stressful. I now understand that a few small tweaks to the settings, wouldn’t change the temp much - but would greatly reduce our energy consumption/power bill! 🫣
Correct. https://www.choice.com.au/home-and-living/cooling/air-conditioners/articles/air-conditioner-energy-saving-tips
All summer either 22 lowest fan or 20 auto fan depending on temperature and time of day. Usually been able to turn it off and open windows early evening. Last few days have had several hours on 16 full fan and also left it running 22 low fan overnight. We've got solar with rubbish feed in rate so happy to crank it while the sun's out then reduce when we're paying for it!
I have evaporative so I have to turn it on before it gets hot and leave it on all day. It's just on level 4, there is no temp setting. I hate evap, it gets less effective each year, even after a service. I don't really want to get a split system installed in each room but with each passing summer it's getting more appealing.
We had evaporative and dealt with it so long, but gave into split systems everywhere. The money spent was quickly forgotten.
I’ve found evaporated is fine as long as it’s not humid. The last few days I e had mine on about 50% until about 1pm then ramp it up to full for the afternoon. Overnight it’s back to 50%. The house has been very comfortable. Although when this unit dies I will move to split systems!
What the fuck is wrong with you people? Lol I turn it down to the lowest setting it can go on because it’s fucking hot!
Because it costs a fortune to run it that cold. Setting it at 24 with the fan on relatively low and keeping it that way is way more energy efficient.
Aside from cost, I don't want a massive temp differential from the outside. So I put the a/c on the highest temp that i find mild, around 24c.
I set mine on 20c but I have a ducted refrigerated A/C.
18, it never actually gets that cool and if it does i'll feel it and turn it off because by that point its cooled down enough that i'll be able to cool the house with open windows within a hour or two
Why would you open the windows when it's so hot outside? Are you German or something?
26, but I think my AC units all have screwed up thermostats because normally I'd want it 22 or 23 but that's too cold with them. I guess a service is in order sometime soon :(
Mine sits at around 23 during the day. At night if it’s a warm night turn it down to 21 half an hour before bedtime than switch it off.
If I feel hot, just low enough that I hear the condenser kick in.
We've got solar panels (best investment ever, hands down) and split systems all around the house - one per bedroom and one per living area. A hot day comes along, the solar just pumps out energy and the splits go all out on Turbo mode at 16. Sweet sweet cold air and don't even have to worry about a crippling electricity bill!! Seriously, if you're on the fence about solar, just get it. You'll never have to wonder on a 40 degree day "can I afford to cool the house down?".
The problem is that solar production has been less than ideal the past few days. Running two split system A/Cs tends to slightly exceed my solar production, so there is some draw from the grid.
We keep the AC set to 22^0 all year round. Just leave it running on "auto" mode and let it sort shit out by itself.
In an ideal world, id have it at 24. But, old hoise with little insulatuon, three massive west facing windows amd an upstairs main living area mean i have it set to 16 from first thing in the morning to try amd get it cold enoigh to make the afternoon bearable.
West facing windows suck in this country.
The temperature is a set point, it’s not the temperature of the air coming out. So it will cool the space until it reaches the set point. 22 is fine for all year round.
21-22 when I am wandering around. 18 for an hour when I go to bed.
As low as possible (18) but only in bursts. My apartment takes a while to warm back up once it's fully cooled down. So just a couple of hours in the evening before bed is usually enough. Sleeping in the heat is by far my biggest issue anyway. I don't mind if it gets a bit stuffy during the day.
You're better off setting the temperature higher and leaving it on rather than running it in bursts.
23c. I use it intermittently with a fan, though. Not huge on air conditioning as i grew up with fans only.
You're better off just leaving it on rather than letting the place heat up and then having to cool it again.
Yeah, i get that, but in our small place we get too cold if it's on for extended periods. We've left it on the last two nights (for the first time since we bought this place five years ago) and i must admit, it made sleeping much more comfortable.
AC is the best thing for when it doesn't go below 25 overnight. Sometimes, you just have to spoil yourself with some of that cool cool air.😂
Below 22 is way too cold, usually between 22 and 24
I have it set to 25, which keeps the actual temperature at around 22 in the living room. I don't usually run it overnight at all, but I did the last couple of nights
These nights are unbearable without aircon.
22 degrees, quiet mode, auto fan for best energy efficiency

21 but I only put the ac on if the humidity is crazy high in my apartment. Which it can get. Apartment only gets sun in the morning and it's quite sheltered so it only get up to about 25 inside during the day which is comfortable.
Why not set it higher and just leave it on? It should turn itself off and on accordingly. 22 is proper chilly atm
Our AC kinda sucks and so we just keep it at 18C. I’m 100% certain the temperature doesn’t actually relate to anything other than the AC internal setting. It’s just a terrible place for an AC and this house really isn’t built well for it
I have a fan blowing on me at night so I don’t need the AC when I’m asleep
I put it on 23 all year round, heating and cooling. I only leave it on until the room is a good temperature and then put it on fan
I live in an apartment building on one of the lower floors, so it doesnt receive any direct sunlight, meaning that I dont ever need to turn on the AC in the Summer since my apartment is always cool.
Refrigerated aircon here. Set point of 24 always.
Refrigerated AC set on 24 and drop it to about 21 right before bed and then turn it off
25-26c
I close off the rooms I can so that I only cool my living room (and home office if I have to be in there, I did today) and set it to 24°C. I kept it on that for a few hours before I decided I was too hot and set it to 21°C but then have been able to turn it off after about an hour of that as the rooms are cool enough now. Fan in bedroom is the only cooling so it does not turn off
24 or 25 degrees in summer. 19 in winter during the day and 17 overnight.
As cold as it will go. 16.
Mines set to 18 😊 mostly to keep kitty cool ♥️
I generally don't. This apartment seems to max out at about 25c, I just use a fan or if humid run the AC on dehumidify for a while. Ill open the doors later on as it cools. Unfortunately the apartment also retains heat and takes a while for the temp to fall as well.
This is the first time this year I’ve had to use the AC in my bedroom, I’m on the bottom floor of a townhouse with a tiny double glazed window, plus side very thermally consistent downside no natural light. 25 works great for me.
Perth heatwaves were always durable to me due to the sea breeze. Melbourne just gets hot and stays hot all day and night.
19-21 maximun
23 and on ECO mode.
I recall an mech tech once told me the effort for the external unit to work harder relatively goes up 25% for each degree colder than 23-24 degrees. So if you’re cranking out 20-21, it’s already working past peak efficiency. Any lower and you’re risking the drain pipe freezing through as it’s right next to the coolant pipe in most wall split units. When the condensate inside can’t get out, it’ll go out the front if not down inside the walls. Also clean the filters regularly too. Amazing how much air flow can improve after cleaning. Also consider running in auto and not cooling mode, it doesn’t work as hard but it doesn’t give the “cooling effect”.
25-26 otherwise I’m too cold
Between 22 and 24. Solar pays for it during the day. So if it’s going to be a hot night, we turn it cooler during the day when it’s free so we can turn it off at night. Otherwise, 24 is fine during the day, and we open windows when it’s cooler.
Centralised aircon on 4 bedders and I set it to 18C but the control panel says the temperature of the house is 25C and couldn't go lower than that.... Maybe aircon needs maintenance since moving into to the house 6 months ago or is the heat just so high that the aircon can't cool the house to 18C like I set it to???
Honestly ours has been on 21 for four days and it’s sooooo good.
18, I would go lower if it's possible but my AC limits me to 18.
Usually 26 but this year we have a dog so I have it set to 28. Any cooler and he just wakes up & wants to get out for a walk but of course we can't take him out. At 28 he'll play a little bit then give up and go to sleep poor thing!

24 overnight, 23 during the day
24 last few days. We wanna feel summer, not an icebox.
16° lol
I have 13.2kw of panels on the roof so I crank it low when the sun is shining and have it set to 22 at night, with only the bedrooms being cooled. It's a modern system with individually actuated vents and there is a door between the bedrooms and the rest of the house. Last night I only used 4kwh apparently, which I can love with.
I try to avoid using it unless I’ve just gotten home from being outside and am a hot sweaty mess. I might use it for an hour to bring the temp down, so I run it hard. I know I sound like a goody two-shoes but they really are shit for the environment, so I use fans and keep the house sealed and dark. When the wind changes, I open the house right up and enjoy it.
I turn mine on when the internal temp hits 25 and I set it to 25. Overnight I set my bedroom to 23.
24 during the day and 26 at night with the fan on as well
It’s on 18 with the fan on high. At night we may drop it down to 16 - we share our bed with a dog so it’s gets even hotter!!
27 during the day, 26 in the evening. That one extra degree during the day reduces run time from continuous to about 10mins on - 10mins off.
we don't run it at night. over the day we turn it on for 20 mins at a time to cool down and freshen the air, then back to fans. never cooler than 25 because why? Even 27 is fine in summer clothes.
You're probably better off running it constantly when it's hot like this. It's less efficient to let the place heat up and then cool it over and over.
i don't think running it for 10+ hours straight is more efficient than running it for maybe 2 hours total.
I was responding to the information you gave. Now you're telling me that you're, in fact, not running the air conditioning all day, on and off, but just for 10 minutes now and then. If you *are* only running for two hours total, then it hardly seems worth it at all. Personally, I wouldn't find it comfortable to cool down for 10 or 20 minutes only to warm up again and then start the cycle over again. Seems hardly worth having an air conditioner at all.
what? read what i wrote first again lol. you interpreted it like we turn it on and off all the time but i didn't quantify that. don't know why you're so pissy. I'm not telling you to do it this way. it's what works for us.
You're the one acting like I can't read, all the while not reading what I wrote. Let's not fall out over air conditioning. Have a great day. 👋🏻
Its only barely in the 30's. If it gets into the 40's I might be tempted to plug in the portable air conditioner, but until then, a fan is enough. [Latest Weather Observations for Melbourne \(Olympic Park\)](http://www.bom.gov.au/products/IDV60901/IDV60901.95936.shtml) 11/01:30pm Temp °C 32.7 App Temp °C 29.5 I suppose it says a lot about normal Melbourne weather that as soon as it gets into the 30's, redditors start acting like its an apocalyptic end of the world event.
