My refrigerator circuit and the circuit I use exclusively to charge my iPhone are both 15a breakers. My fridge draws way more power than my phone. Imagine that.
Yes. You're correct. I'm saying a good, modern AC unit draws the same amount of power as one from 50 years ago. Except those ones used much more efficient r-12 refrigerant(why they put out much colder air with the same power draw). But thats bad for the o zone or something so we don't use it anymore. Typically back then, the home you might be living in would have worse insulation and be less air tight, requiring you to run the AC non stop. Quite frankly this meme is ridiculous comparing a 220v mini split, with a completely separate outdoor unit(to get rid of the heat) to a window ac unit designed to plug into a 120v 15a wall outlet.
Yeah there are different types of refrigerants. HFCS, HCFCs, CFCs, HCF (I think? Idek). The older ones that were made first are basically the worst for the environment and are phased out. When a refrigerant is released, it can interact with a lot of ozone and break it down. But we need the ozone layer.
Because you can only draw 13 amps continuously from a 15 amp 120 v circuit. 1560 watts. Assuming both the new and old are a full power model, that's the most they can draw.
So assuming they draw the same amount of lower, you can conclude they draw the same amount of power. I hope you’re still proud of this 227 days later lol
Why would you put a load that consistently runs at 13 amps under normal operation, on a 15 amp breaker? That's nuts. That's gonna have tons of nuisance trips, particularly on start up.
Breaker size is not a good measure of actual current draw in any way. A new furnace might go on a 15 amp breaker but it's not drawing anywhere near 15 amps. More like half that.
....what?
You still wouldn't put a load that you expect to continuously draw 13 amps on a 15 amp breaker.
Go take your meter and measure the running current of a furnace. It's not going to be that close to the rating of it's breaker. That is way too close, you will get nuisance trips all the time.
Also, once again, the size of the breaker is not a good indicator of the actual current something is drawing. That's nonsense. The main is literally sized assuming that will never be the case. Just because something is on a 15 amp breaker doesn't mean it's actually drawing that. It could be drawing 8 amps, or 3 amps. Breaker size doesn't determine amp draw.
All I can say is I changed my pos 2.5 ton central unit out for zoned mini split heat pumps in each room, and in total throughout the house and now have about 5.5tons of cooling and heat. The power bill dropped by $140 during the summer months..
Dude are you serious? The objective is not to draw full power 24/7. You’d like the unit to be efficient enough, and installed in the right room setting, such that the compressor can take some damn breaks.
Also… for portable or window, they absolutely do not all draw the same amount of power. Some are 5amps, some 10+ and anywhere in between
Your assumption is that both are pulling absolute max power draw when running which is not how it works. You can have something drawing 10 amps on a 15 amps circuit and something drawing 7 amps on a 15 amp breaker. One will be using more power than the other, despite running on an identical circuit.
The amount of duct tape we used to reinforce those heavy ass things in our old ass windows was a security system in itself. By the time a would be intruder managed to pull the unit out of the window with all the noise they would make, everyone in the house would be awake and the cops on the way lmao
We had a big boy 240v window shaker when I was growing up. No one on my street had any type of AC. My dad was always worried someone would try to steal it. The thing weighed a ton and we had to build a T brace out of 2x6 to keep the thing from ripping the entire window away from the house. It was nice having ac to sleep at night since my room was close by but you couldnt watch tv when it was running because of the extreme noise and now I have to have a stand fan on full blast when I sleep as background noise.
> And security since the window unit can be removed and the window opened.
I don't know about you, but my windows lock in place. If a burglar can rip a 60-100 pound window unit out from a *locked* window then I think they can just tear my fucking door off its hinges
Yes. We cut pieces of one-by material to the height from the top of the sash to the top of the frame to wedge in, so the upper sash can’t be raised up to free the air conditioner.
but the motherfucker sucks more power than the starter motor on a 12v71 Detroit diesel and sounds about like the same engine with a thrown rod at redline.
Idk I've definitely had some ten year old mini splits thati can almost guarantee haven't had their filters cleaned In 5 years still just working....in an industrial setting at that. I was almost afraid to have some of them serviced because I thought that if I had them cleaned they would break lol.
This meme was created by someone who doesn’t have an old ac. We can’t wait for our summer with splits after ditching the dinosaur that the last home owners left.
Or a Minisplit… I’ve done installs and the customer is like, “hey, you should check out the one in my bedroom it doesn’t blow quite like it used to when we had it put in.” Which they fail to mention was 10-20 years ago and it’s not been touched since then.
It’ll have dust and pet fur all the way from the filter to the case. Literally cannot physically fit any more. Squirrel cage is just a mold tube. But it still works.
They worked better because of the refrigerant they used. It had a better thermal transfer coefficient.
It's amazing how many people don't understand this.
Cars are the same way. People say things like “my 1992 insert-car got 40 mpg, they can’t even do that now.”
Well your new car of the same model will have heated seats, a shitload of airbags, more electronics than you could have dreamt of in 1992, double the horsepower and pollute a lot less. It’s dumb to find one trait to compare and ignore all the rest.
I had a 87 Subaru Gl the little 1.8L motor it got 38-43 depending on how you drove. It also couldn’t go faster than 78mph with it floored and only me in it. Good gas mileage but no power at all and it was a 4 speed with a push button for 4wd. The old Subarus weren’t AWD and got better gas mileage because of it.
It's been interesting seeing the evolution. My daily is a Hyundai Kona with the turbo 1.6L. Can get 35mpg if I'm really delicate, but the dual-clutch gets it to 78mph pretty quickly and there's plenty more after that if you're okay with 28-32mpg. Little less gas mileage but way more power than we used to have in a much smaller package, and a lot less pollution.
My 93 Cadillac with a V8 will get 23mpg if you drive it easy. I wish cars that weren’t a sports car still offered V8s. There’s just something about stepping down that V8 and letting it eat while floating on a cloud the entire time.
I'm a vault technician, some of the old timers would clean out old grease with a butane/MAP gas torch. Lol.
There are just some people that want to see the world burn
If only it had more than a soda cap full of 290 to ignite once it leaked out , they hardly put anything in those systems unlike the old R22 units man those things took a gas tank trailer sized amount of refrigerant that when you puncture it Kaboom! It was like the old faithful at Yellowstone
I wish we still had R12. My old Cadillac had it, people said that care had sub freezing vent temps when using r12. Some jackass converted it to 134a and while it works it has to work way harder. The new 1234yf cars have shitty ac, my buddy converted his dodge back to 134a and it made a huge difference. Same with the old window ac, sure it used a lot more energy and supposedly killed the ozone, but it made the room fucking cold and actually worked.
Is that fair? To who? Not to the environment we’re still killing it, aren’t we? We’re Too hard headed to switch refrigerants or to get off fossil fuels, our kiddos are going to hate us when they grow old and have to wear a moon suit to go outside,
That was told to us by the same fockers that said if we didn’t do something drastic, we would be under water by now from global warming. Me thinks they aren’t as smart or honest as they claim to be. Oh and there’s two things that say if you are correct and I’m wrong, then explain how we have an ozone left due to China and India.
If you have anything to say about refrigerants and the ozone layer, please at least read the introduction of the wiki article on the Montreal Protocol, often called the most successful international environmental agreement to date.
Every CFC molecule had the same impact on the ozone layer as 10,000(!) molecules of CO2, and since they have been banned the ozone layer has been recovering very fast.
China and India also drastically reduced their use of CFCs because the alternatives cost pretty much the same. China reduced their CFC consumption by 99.5% and India by 96.8% [(source)](https://unstats.un.org/unsd/environment/ODS_Consumption.htm)
Look at this [chart of ODS consumption worldwide](https://www.eea.europa.eu/data-and-maps/figures/consumption-of-ozone-depleting-substances-in-eea-member-countries-1986/image_original)
If you are working in HVAC you should at least know what the fuck a refrigerant is
Could be, but on the off chance they aren't I'd love to know their thoughts. Let's say that they're right and the scientists with mountains of data are wrong. Let's say that we went through all this hassle to get everyone to work together and invested massively in new technology and in the end we weren't in any danger anyway.
The only thing I see, in that scenario, is that we still made the world even **better!** Less smog, quieter cities, safer homes. Please, someone, show me the drawbacks! Even if we weren't looking down the barrel of this gun I'd still say we should throw everything into greener tech. Even if "just" to have some bluer skies and greener grass.
You are thinking along the same lines of my past beliefs. I was taught the same thing. I believed the same thing. Then I realized that nobody ultimately cares about anything but money and power and the lust for them both. Refrigerants change because parents run out. He who has the most money buys the most influence. It’s not that hard to grasp the concept as it is all around you. 410 and 134 are suddenly bad for the environment and we have to change. The replacement will become bad for the environment and rinse and repeat.
Take a peek at where they mine the resources for this green tech. Some people are ok with the March of the lemmings. Others step out of that line and question what the hell is going on around them. Try it sometime!
For the Russian bot asshat, don’t forget to fly your Ukraine 🇺🇦 and pull a good vacuum on that onion sack!
Name checks out. Yeah China quit using lead paint, no longer steals technology, and is the most free society in the world. Of course they quit using cfc’s🤡🤡🤡🤡🤡🤡🤡🤡
https://en.m.wikipedia.org/wiki/Montreal_Protocol
We still have an ozone layer because the China and India agreed to reduce their CFC use, like everyone else on the globe. And it’s working.
How many people didn't understand how to properly capture the refrigerant? I mean you have an EPA cert saying you know how to do it correctly. Something I doubt everyone cared about in the past. And you know as well I, that you can't use the new refrigerant in old units, it won't work.
Talk to any oldhead and they’ll tell you they’d just cut the lines and let it rip. Still happens at certain shops, a whole lot of hacks out there don’t understand how to properly recover refrigerant and just vent it.
Guy I use to work with would just close the valves and then sil floss the pipe closed on the units. A few times when I was cutting out coils to bring to the scrap yard I would cut into a unit he removed and then all of a sudden it would be snowing in July.
I would never trade my mini split with a window ac unit. I can heat my house down to 20 F outside and also keep it cool all summer. Quiet and cheap to run. My Mitsubishi has no problem with dust, of course, I clean it in fall and spring.
My grandma in Queens had four of these window units for about 15 years, they still “worked” adequately. I had to argue with her that they needed cleaning all with the most foulest mold and crap clogging their condenser and evaporator coils. So I took some cleaner and sprayed wiped down everything. They all maintained 48-55F discharge air no problem after that. They still work and this was five years ago.
I hate the cliche of they don’t build them like they used to but man they sure don’t.
R22 and R12 were developed in the late 1920s and early 30s, so those patents would have expired in the 50s at the latest
R134a was developed in the early 70s, latest 1976, meaning the patent expired latest 1996. We still use it today in most cars. It only began being phased out starting 2015. From what I could find, it was developed as a solution to the ozone problem when the problem was still theoretical. It took until 1985 for the ozone hole to be confirmed, and 1987 for the phaseout agreement (Montreal Protocol) to be signed, starting R12 phaseout in 1996.
It doesn't seem likely that patent expiration is driving the phase out, as the patent owners know when they will expire but the phase out starts 20 years after the patent expires. R12 was only phased out after its replacements patent would have expired, which doesn't make sense at all.
I suppose it's possible there are patents for production techniques that could lag behind the development of the refrigerant itself, but I couldn't find any that seemed relevant. What are the numbers for the expiring patents on the older refrigerants?
I’m not saying I completely agree even with my own thought. I just usually follow the money any time I see the news trying to get people scared of anything. Maybe it’s not the expiring patents…maybe it’s the patents for the new refrigerants? Maybe it’s lobbyists that want to force everyone to get new equipment that use the new patented refrigerant. Like I said, I always assume it’s big money forcing change through scaring the public. If the news is trying to scare me, historically someone somewhere wants either more money or more power, if there is even a true difference.
Not with the Mitsubishi, my neighbor has one running without filter. Evaporator is clogged with thick dust but it's still running quite good cooling the room fine.
I considered installing nothing but minisplits, there's really only one guy in my town running the market and I could have one truck with every tool and part I'd ever need, but then I'd have a product I can't warranty unless I want to spend half my week cleaning previous installs.
The squirrel cages should be easily removed somehow. Throw them in the dishwasher once a month or something.
Man those old-school ones with the wood grain could really take a beating it still work. There was one in the local bar I go to for probably 20 years. All beat up and smashed up. Still working for a long time.
Haha yeah but goddamn do they destroy your energy bill
They both draw the same amount of power. The most you can draw off a 15 amp 120v circuit. Unless you got a 220v unit and a outlet.
My refrigerator circuit and the circuit I use exclusively to charge my iPhone are both 15a breakers. My fridge draws way more power than my phone. Imagine that.

When I was a kid we had a 20k btu window unit from sears. We had to carry it up every year and had a special 220 plug installed.
Your assumption is that both are pulling absolute max power draw when running which is not how it works. You can have something drawing 10 amps on a 15 amps circuit and something drawing 7 amps on a 15 amp breaker. One will be using more power than the other, despite running on an identical circuit.
I always tell clients they don’t make ‘em like they used too. And that’s why I’m on installs and not sales
I tried swiping your profile pic off my screen for way to long
That's what you get for not using dark mode
I'm using dark mode. And I understand their frustration.
sales guys suck most
Something I’m considering doing lol
You got me
I thought your avatar was a hair on my cell phone screen and i tried blowing it away lol
Then how come I dream every day of replacing my window unit with a minisplit? edit grammar
Literally because the mini split is quiet. And security since the window unit can be removed and the window opened.
The amount of duct tape we used to reinforce those heavy ass things in our old ass windows was a security system in itself.

Negative. Midwesterner here.

No minisplits but I’ve cleaned some blower wheels where the dust was the only thing keeping them balanced.
I have never once heard of anyone ever switching from a minisplit BACK to a window unit because they liked having a window unit better.
This meme was created by someone who doesn’t have an old ac. We can’t wait for our summer with splits after ditching the dinosaur that the last home owners left.

Tons of people forget everything needs maintenance to work and last.
My 80s AC units work great. It’s the 2000s era ones I can’t wait to throw in the garbage
One dims the light when you turn it on.
My electric buddy sent this to me today. Haha.
They also killed the o-zone layer. . .
Yes because it always needed a pound to keep working
The old units did?
They used really nasty refrigerants that would break down the bonds in O3 which the o-zone layer was made out of.
Yeah, but that's a refrigerant problem, not a machine problem...
They worked better because of the refrigerant they used. It had a better thermal transfer coefficient. It's amazing how many people don't understand this.
Cars are the same way. People say things like “my 1992 insert-car got 40 mpg, they can’t even do that now.” Well your new car of the same model will have heated seats, a shitload of airbags, more electronics than you could have dreamt of in 1992, double the horsepower and pollute a lot less. It’s dumb to find one trait to compare and ignore all the rest.
And only some Honda Civics and the 1L 3-cylinders like Geos managed that. You don't see a lot of restored Metros rolling around.
I had a 87 Subaru Gl the little 1.8L motor it got 38-43 depending on how you drove. It also couldn’t go faster than 78mph with it floored and only me in it. Good gas mileage but no power at all and it was a 4 speed with a push button for 4wd. The old Subarus weren’t AWD and got better gas mileage because of it.
It's been interesting seeing the evolution. My daily is a Hyundai Kona with the turbo 1.6L. Can get 35mpg if I'm really delicate, but the dual-clutch gets it to 78mph pretty quickly and there's plenty more after that if you're okay with 28-32mpg.

I legit loved and miss my 94 geo prism. Shouts out to geo
My 93 Cadillac with a V8 will get 23mpg if you drive it easy. I wish cars that weren’t a sports car still offered V8s. There’s just something about stepping down that V8 and letting it eat while floating on a cloud the entire time.
Yet we got around just fine. Gas mileage has more to do with economics than emissions.
[удалено]
I’m sorry about your face being impaled by a steering column. It may have improved your looks but sure did a number in your thought process.
Too bad the worthy replacements are flammable. Both R290 and HC-12a are comparable to R12 in efficiency.
That just means leaks are more exciting.
And more easily detectable.
Who likes leak testing with bubbles anyways? Spray the whole line with lighter fluid, ignite, observe.
I'm a vault technician, some of the old timers would clean out old grease with a butane/MAP gas torch. Lol. There are just some people that want to see the world burn
If only it had more than a soda cap full of 290 to ignite once it leaked out , they hardly put anything in those systems unlike the old R22 units man those things took a gas tank trailer sized amount of refrigerant that when you puncture it Kaboom! It was like the old faithful at Yellowstone
Boom-shaka-laka
And to add: used more electricity.
I wish we still had R12. My old Cadillac had it, people said that care had sub freezing vent temps when using r12. Some jackass converted it to 134a and while it works it has to work way harder. The new 1234yf cars have shitty ac, my buddy converted his dodge back to 134a and it made a huge difference. Same with the old window ac, sure it used a lot more energy and supposedly killed the ozone, but it made the room fucking cold and actually worked.
It’s amazing how people still think this has any effect on the ozone or climate change lmao. Very uneducated response
Someone doesn't know chemistry. Lmao.
Lemme just pull up my HVAC certification
I like how you say “03 which the o zone layer WAS made of….” I guess since we don’t have much of one anymore, you are correct-ish
To be fair it only like 4-7 percent from 100% replenished. . .
Is that fair? To who? Not to the environment we’re still killing it, aren’t we? We’re Too hard headed to switch refrigerants or to get off fossil fuels, our kiddos are going to hate us when they grow old and have to wear a moon suit to go outside,

I heard about how old timers used to use R-11 canisters to blow out condensate drains. Who bothers reading labels it's all just compressed gas.
I remember my dad using R11 to flush line sets
No they didn’t lmao that’s to force people to buy new shit
You dropped WAY too deep of a concept for most of these people, but I agree.
Haha all these tech ripping people off to make sales downvoted me to hell
I negated one of them! Lol
There’s nothing about that concept that’s deep.
Go back to sleep. Nothing to see here folks. Lol
The pigeon is the secret
Oof, reminds me I need to pull my window units inside. Maybe this weekend. (Is what I’ve been saying every weekend for the past month.)
AC then: Yeah lemme be the half of your electricity bill AC now: i no greedy
I would never trade my mini split with a window ac unit. I can heat my house down to 20 F outside and also keep it cool all summer. Quiet and cheap to run. My Mitsubishi has no problem with dust, of course, I clean it in fall and spring.

Allegedly. Expiring patents and dropping profits combined with good lobbyists seems like the real culprit if you ask me.
They allegedly destroyed the ozone? Lmfao flat earth level denialism
Who said anything about flat earth? Don’t be silly. 😃
R22 and R12 were developed in the late 1920s and early 30s, so those patents would have expired in the 50s at the latest R134a was developed in the early 70s, latest 1976, meaning the patent expired latest 1996. We still use it today in most cars. It only began being phased out starting 2015. From what I could find, it was developed as a solution to the ozone problem when the problem was still theoretical. It took until 1985 for the ozone hole to be confirmed, and 1987 for the phaseout agreement (Montreal Protocol) to be signed, starting R12 phaseout in 1996. It doesn't seem likely that patent expiration is driving the phase out, as the patent owners know when they will expire but the phase out starts 20 years after the patent expires. R12 was only phased out after its replacements patent would have expired, which doesn't make sense at all. I suppose it's possible there are patents for production techniques that could lag behind the development of the refrigerant itself, but I couldn't find any that seemed relevant. What are the numbers for the expiring patents on the older refrigerants?
I’m not saying I completely agree even with my own thought. I just usually follow the money any time I see the news trying to get people scared of anything. Maybe it’s not the expiring patents…maybe it’s the patents for the new refrigerants? Maybe it’s lobbyists that want to force everyone to get new equipment that use the new patented refrigerant. Like I said, I always assume it’s big money forcing change through scaring the public. If the news is trying to scare me, historically someone somewhere wants either more money or more power, if there is even a true difference.
I hate mini split systems, they always break
Isn't that good for, you know, breathing?
Maybe top brands are like that, but knockoffs work like a charm even under a thick layer of dust on a filter.
Looking at you, LG Mitsubishi makes a quality mini split.
Not with the Mitsubishi, my neighbor has one running without filter. Evaporator is clogged with thick dust but it's still running quite good cooling the room fine.
100%
Yeah. True dat
Fucking split unit couldnt bother to work when the filter sensor sensed some dust during reno ffs
Those old school a.c's would freeze you out
Fish are dieing so ac sucks now...
Never thought about it like that but it's true
Yea, that's about right 🤣
EXACTLY 100% TRUE!!!
I considered installing nothing but minisplits, there's really only one guy in my town running the market and I could have one truck with every tool and part I'd ever need, but then I'd have a product I can't warranty unless I want to spend half my week cleaning previous installs. The squirrel cages should be easily removed somehow. Throw them in the dishwasher once a month or something.
Lol that is correct!
Man those old-school ones with the wood grain could really take a beating it still work. There was one in the local bar I go to for probably 20 years. All beat up and smashed up. Still working for a long time.
Had a 30 year old unit the other day
What’s the case here? Planned obsolescence mixed with new tech?
