Me: opens window. Mosquito: hehe

Step 1: open your fridge Step 2: get inside the frdige

This definitely works, I've been doing this for a few years and haven't used my AC in 3 years. I live in a 2 story house, so my fan points outside from an upstairs window, and the other window is open downstairs. Since warm air naturally rises, I don't bother with a downstairs fan pointing upstairs, and my house in the morning can be pretty chilly. People look at me strangely when I try to explain this technique, so I will definitely be sharing this video.

Pro tip: Place the fan like between one or two meters away from the window. This actually increases the outflow of hot air, thereby increasing the inflow of cold air.

This technique saved us! Actually works!! We have no AC and kids were sweating and crying! Now glad we can sleep cool! Thanks for this💕

It’s literally soo hot that it’s cooler inside than it is outside

One note: If you are at home during the hot day, bear in mind, that every piece of electronics you use, creates additional heat, that will accumulate in your house over time. Using electronics, that has high temperatures in load (like a PC/laptop/console during gaming sessions, owen, kettle, etc.), will eventually build up the heat inside - as there is hotter outside, the heat will just keep accumulating - you might end up in an enviroment with much higher temperature, than outside temperature. Also, sometimes it´s actually better to leave your windows open during the day, even tho the temperature outside is much higher. The difference between outer and inner pressure will make the air move, making the high temperatures more bearable.

I’ll save this video... for next summer 😂😂😂

This is great advice for people who live in areas that actually get cool at night. I *really* wish I could just keep out the heat during the day and then air out the house at night and skip the AC altogether most days. No such luck in the southern US where our summer "lows" are 75F with near 100% humidity. Works great for about one week in April and another week in October, though!

So it was about 85 degrees today I’m on the 3 floor in apartment. I’ve been staying at a friends when it’s hit like today but today I tried this and to my amazement it really worked. My friend came by and was shocked as well. ❤️

Most window fans have both an intake and exhaust setting. Place the fan facing inward in your bedroom and set it on intake and it will pull in the cool night air just as well as the method described here. Works when you don't have access to a window located across the house.

the motion graphic is lit

Ladies and gentleman its that time of the year we all love. The "staying up at 3:00 because its too hot and cannot turn the fan because its too loud" time. I still have no idea why summer needs to exist?

I was suffering for months after moving into a new house around the end of winter. I live in on the second floor, which is basically the attic; I couldn't concentrate on my studies and had to resort to studying in the library most of the time. I hope this video may help me stay cool next summer🤗

Thanks for advice... my mom also uses this technique, she knows it for a long time now, she does this without fans, without electricity , she opens some windows and doors during night, and closes everything during day

I do keep the window blinds closed during the summer to keep the sun rays out, it makes all the difference.

Currently dealing with a heatwave in the UK... ITS TOOO HOT AND US BRITISH ARE NOT USED TO THIS!! We only know rain!

“How to keep your house warm while it’s hot outside”

I tried this all the time, of course it works, but it have glaring security issue; on an apartment situated above the ground it is okay to use Fan & open windows but on a bungalow on the ground you need to install windows grill, insect net, and a dedicated exhaust fan to keep unwanted stuff outside.

The drapes that block out most of the light are awesome in the summer.

I've been doing thie fan thing since mid July. It helps. But the smoke from all the fires gets sucked in too; especially at night and early morning.

1. Turn off your ps4 2. Go to the river 3. You realize you don’t need to stay in home

Great info and the most soothing voice I’ve ever heard.

Well gosh summer is almost officially over :)

I used to sleep on the floor. Our house had a than below. concrete foundation, which stays cooler than the ambient air. Also, heat travels upward, leaving it cooler

Get a metal bucket. Fill it with ice. Place the bucket in front of the fan. Point the fan to you.

Now I just remembered what I did once as a University student, during the hottest summer I can think of: I put my pajama in a freezer for 45min. and then I put it on! lol BTW: This fan-technique works 100%. After the sunset, you must place it approx. 1.4m from the window and direct it to the bottom of your window (in any room facing south at the top floor), since the hot air goes up. Open your windows facing north at all floors. Get roller mosquito nets for your windows! Done.

0:30 pick room to cool, open window to let cool air in. 0:42 across the house open window and point a fan outward to blow warm air out and create a low pressure system in house sucking cool air in through the first open window. obviously you need window screens and obviously the outside air must be cooler than the inside air by 5F+ to feel any benefit.

Humidity level at 94%, temperature at 36°C, realfeel at 47° C. Wellcome to NorthEast India Summer.

Seattle 2021 (June) today it’s only 84 haha Monday will be 100... funny how it’s mild but feels hot.

I figured this out for myself decades ago in a house that got particularly hot in a hot arid environment. We used swamp coolers so the windows needed to be open for it to work well but for some reason, suction of air out the window didn't occur. So, I placed a fan blowing out the window of the hottest room and it worked well for us.

Cool without ac? Easy. I'll do it with ice. Just put my head for a few seconds in the freezer. Refreshed. Repeat

I'm dealing with a heatwave in Cleveland right now. My peener is stuck to my leg like a sweaty slug.

Better late than never, eh?

This Technique really works, thank you guys.

this actually works lol. I stay In a small room with 2 windows. I pointed one fan out and the window if front of my draws in colder air. Its like having AC on very low though

Try this in Taipei, good luck when its super humid,with typhoons andeven at night,the heat is around 38 C.

Moving up to Washington, from California, I was really alarmed that homes don't have A/C up here. "Oh it doesn't get hot in WA, you'll be fine." Then it immediately goes up to over 100. It was warmer here than in my hometown. Granted, I'm well aware that's not normal, but I just have the worst luck in the world. I will be using these tips, to help out in the more mild heat we now have.

Great! It’s 85 in the house right now but the suns going down so I just set up my fan and windows. It’ll get down to 70F tonight, so fingers crossed! Tomorrow it goes back down to 45F at night, I can’t wait

Genius work.. couldnt have figured this out without you guys.

Ninja Technique: Plant tress🌾

Move bed to basement. Get additional whirlybird for roof. Insulated roof.

Her voice is soooo soothing! ASMR triggered x

this helps so much my bedroom gets so overheated with me in it i get sick so more ideas help me avoid getting sick! 👍

In the UK trying to prepare for the 40 degree Celsius heatwave 😭

From a lifetime of experiencing Australian heatwaves, a hot land. Proper insulation is something often overlooked and it really does a big job (without extra cost when you have it in place.) And especially when AC is an issue either the cost or not having any. Insulation will lessen costs of heating in winter too. With climate crisis now, insulating properly is now more important. It will get worse, so put work into insulating your living space properly - it is your refuge. Temperature transfer is most between roof and windows. Roof insulation is first priority. A heat removing fan can also help in roof space. Keep sun off windows BEFORE IT ENTERS, with external blinds (cheapest are bamboo ones). Using light internal blinds does not help as much because the "glasshouse effect" has already happened, heating the air in the home as sunlight enters through glass. But if can't have external blinds, you can make the internal blinds more insulating first by having a pull down blind that close fits the window space. We also have heavy (reflecting backed) drapes that can close the windows off more. Less mobile air in trapped window space acts like an insulator. The major insulating measures of roof and windows really do slow the house gaining heat in summer and loosing heat in winter. The more you insulate the more effective are things like fans, and the cheaper it all is. Once you have good insulation going it is forever. No more costs for it once it is in and paying you well back. Get things closed up early in the morning on heatwave days.

Also you can use emergency blankets to cover windows to reflect sunlight

Good ideas we did similar stuff when we were in coastal CA, but what about when the “cool” air is still in the 80s?

Dosnt help when nighttime is still muggy and humid just allowing all the hot air in again at night

Lookup "whole house fan". They were very common in the days before ubiquitous air conditioning. Also, most two story air conditioned houses are running on a single zone heating/cooling system with the thermostat on the first floor. They are designed to heat, not cool (using the word "designed" generously here). When used to cool the upstairs, a large temperature gradient develops between upstairs and downstairs (where the single thermostat is installed). This happens because most of the air return and supply is happening on first floor and that cool air never rises to the second floor (in the winter heating season the hot air does rise, so it works fine). When cooling, to get 22 C upstairs the thermostat, downstairs, has to be set to a lower temperature - possibly much lower depending on the layout of the house and the size of air vents. Resolve that by restricting the lower floor return vents (assuming you upstairs return vents) and first floor supply vents. That will pull more stale hot air from the second floor and push more cool air directly upstairs. That upstairs cool air will naturally sink to the first floor and the end result will be uniform temperature. It's a hack, but it's easy and works really well. I do this to my house at the beginning of every cooling season. Don't heat the house when configured like this, in fact, shut off the gas while configured like this to ensure you don't accidentally heat. p.s. Houses should be designed with two zone heating/cooling systems to begin with. It's not a huge additional expense if done when the house is built.

Didn't have AC when I was in school and teachers used to argue with me about this subject. Wish this video was around back then

Really instructive I'll buy a big extractor just for that ! now!

Well we hit 39°C! in England yesterday so I’ll try this.

I've been doing this for years and I'm a big "fan" of forcing air out of the house, however if you have a basement place the fan in the doorway and suck the air out of the basement. It works best if you can place something around the fan covering the remainder of the doorway. A sheet would do the job.

If you have exhaust fans, it will help a lot

Thank You for The Tips

My Dad taught me this year's ago He was a smart man

Pffffffffffff......yeah ok....try this in Florida and let me know how it goes

Very well explained

I’ve been doing this for the last 20 years. And only use my air conditioning about five-10 days in the summer during the hottest week or so (over 30C). My windows will actually fit box fans, so the air exchange is very efficient and reasonably fast.

What a pleasant voice

its 95 right now in holland. I am not used to this. I think I am melting

Circulation pump...200 ft of hose in a loop buried a few inches below the ground...and a rad with fan. You'll need a dehumidifier as well. But your probabaly already running one. Run the cooled antifreeze thru the rad...just make sure you don't have a leaker.

This is a cool technique, will try it out later 😉

2 very important tips when using an airco! NEVER! direct the cold air flow at yourself! This can lead to stiff muscles and bones, muscle pain, and even very painful mucous membrane inflammation! 2: ALWAYS make sure that the humidity is always between 30% -50% in the room! Too low humidity because of the dry air of the airco can cause dry skin, an irritated dry throat that makes you susceptible to viruses, and you can end up with a serious bad cold!

It's after midnight here and is 80% relative humidity and climbing. If I open the windows it will increase corrosion and feel hotter than it is. If I use the dehumidifier or AC a little, it will feel cooler than the outside air without expending much energy at all. During the day when there's a breeze and lower humidity I open up. As the humidity increases in the afternoon, I close up again. My power bills are 1/3 of the regional average for a household of the same size. There's only 5c difference between inside and outside, but it feels cooler inside.

You can also do this if you have central air by using just the circulator. If you open a window in one or two rooms you aren't using and close those doors while opening the window in the room you want to cool leaving its door open to the rest of the house, the air in those closed rooms will be forced outside and you'll pull air in through the window that is open to the rest of the house and the circulator system. You might even want to use towels or some other material under the closed door edge to cut down on the leakage under the door.

Even before watching this video, I put a cyclone floor fan in my basement and connected it to a smart plug. I programmed it to turn on when the temp rises above 71 and turn off when it falls below. It works perfectly and makes a significant difference. However it eventually gets warm enough that the fan just stays on, so I was curious what other tricks there me be that I’ve never tried. My upstairs is pretty warm. I think I will try the idea of exchanging the air overnight.

Little late CBC ...

Says someone in Canada. 😂😂😂 Bring your fans down to South Georgia.

Probably best to just build in an air system for that very purpose, and one in the attic too, both auto set with temperature control. A ceiling fan can also promote a decent wind chill, and freshen air.

This is a ranch and it’s a finished basement with carpeting it was 82° down there very well insulated however I need to lower the temperature I’m keeping the humidity between 45 and 50 always this will reduce any chances of mold building. But I need to get the temperature down fast I bought an industrial fan and the attic door has a solid door and screen door option to use what I need to know is how do I get the temperatures down when it’s so hot outside it matches

Omg the the UK summer is so hot. The fan is blowing hot air at me

Since 80% houses don’t have a basement....... lol 😂

Madam we have 50°c on average temperature from june to August. 28°c is heaven for us.

We are now melting in south Texas and north of Mexico. It’s over 40 C (104 F) and power is running out because of multiple houses using milisplits

Actually everyday is summer in Indonesia 😅

What if your room faces the sun for the longest part of the day? Do I leave my windows open or not? I’ve tired that before and it just heats the house up more. Is there something I’m missing?

Wow, thank you!

I turn my heat off when I go to bed in the winter... Just to avoid dry air. I use a humidifier and extra blankets. I sleep best at 60 d f. Mind you I don't wear shorts and sandles in January like some! I do only wear dry fit clothing in summer because cotton is to hot. I will try this recommendation only because it's the heat has dropped.

Her:open window Me: i don’t have a window

Well the main concern is humidity and mosquitoes who just wait outside for the windows to be open.

Well said and quick 👏👍

Everyone in England needs to see this

so useless when it's 100+ outside

Electric fans don't move a lot of air, even swinging a door back and forth moves more air than a table fan or even a standing fan. Open windows on walls that are at right angles to each other, this means that at whatever direction the wind is blowing, the pressure at one window will be greater than the other and air will flow through the house. This is actually how planes measure their airspeed by having openings at right angles to each other and measuring the pressure difference. If you have multiple floors, use the stack effect and open both upper and lower floor windows letting heat move the air for you. Ultimately, evaporation is the way to remove heat. Watering your lawn can lower the temperature a lot, watering your roof could reduce the heat in your home quickly but could also cause a lot of damage due to calcification, an anti-sediment filter could help prevent damage. Wearing an evaporative vest or just wrapping a slightly damp towel around yourself can help you tolerate the worst heat.

Ok will try next year in 45℃ + temperature

It's 74 in southeast Alaska it usually doesn't go past the 60s until mid July or sometimes even August but I noticed it's been getting warmer faster each year back in march or April it reached over 60s and thats usually uncommon I hate it so much😭

As an HVAC technician, I've gotta say this is BS There's only a few (US) states that this will work in. Even so, this doesn't help regulate humidity which is just as important as temperature. Cute video tho

I live in Vancouver. Sorry what is a second bedroom? Is that a thing in the rest of Canada?

Great job 👍

I'm just seeing this for the first May 1st and wishing my windows could open.

Where I live, it does not cool down at night in the summertime. It's still 80 degrees with extreme humidity too.

the moment you woke up the next morning all your stuff is gone...someone broke your house

Texas Cool. Open windows at nite close in the morning. Shades/ Curtains closed to keep sunlight out. If you have a basement with widows open them 2 hrs after sun set with a fan blowing in upstairs window open with fan blowing out. Wait til humidity goes down.outside. No sense bringing humid air inside.

This actually helps

If the temperature is 35, then we feel that it is heaven in Iraq😂😂

1) open window at night = burglar 2) Use darker curtain at window in daylight = a microwave house feel

I'm in Thailand - we have more power cuts now - no AC and fans running..... which helps: wet towels, ice packs and jumping in the pool and sitting on the patio for hours, later with a flashlight or candle when it gets dark to read a book. I hate these unproductive hours

use an emergency blanket (silver mylar cloth) as a curtain liner to keep radiant heat from sun out
