But as your video clearly shows, there's lots of corrosion and scale inside that machine. And as we all know, Once the components of the coil erode, the heat transfer is adversely affected. Therefore, what little efficiency that was gained by the slinger will be lost after a couple of seasons of the stagnant water bath. Then there's the pests attracted by the aformentioned stagnant water. But the video is informative for the typical DIY'er. 🤣

My 10,000 btu window air conditioner came with a factory drain hole. The condensation will overflow without it.... I've had this specific one for 8 years, and it cools flawlessly, and the plants underneath it love it....
@@notkylelol, How much efficiency do you think you lose by draining the condensate off? I’m drilling mine, but using rubber plugs so I can check the efficiency both ways. At most I would expect one seer point. Putting an awning over it to keep the sun off would probably gain more efficiency than you would lose by draining the condensate.
I carefully threw gallons of water against the condenser coils on my window unit and it actually solved the short cycling issues. The evaporator coils were filthy and filled with dust and debris. It was blocking the airflow. Before I poured water onto the condenser coils, I felt very warm air blowing out. That wasn’t a good sign. Short cycling will eventually damage the compressor. I’m glad I fixed my window unit. It now shuts off when it’s supposed to. My room wouldn’t even cool below 85 degrees. My room is cool when it’s hot at now. I’ll do it again if I encounter an issue.
My window unit blows hot air out both sides too. I mean you can tell it wants to cool the air on the inside but it’s just not getting the apartment near cool enough.

Nawww i sure you can get away with it for a while but
If it's draining into your walls then it was installed incorrectly. It's supposed to be installed with the rear at a slant of 1/2" lower than front as to drain excessive water out & away from structure. You drilling a hole just shortened it's lifespan and making it work harder. Do yourself a favor and plug it & prop up front of ac to have it work correctly.
if you didn't install it slanted I'd say you could make a hole in the side of the casing facing the garden so when it gets full it starts draining towards that direction just don't drill any vital components
This is actually written in the installation instructions. Most window ACs require a tilt of about 2 to 3 degrees to drain properly. This means that the back of the AC needs to be about ½” lower than the front. The tilt is needed to keep condensation draining out of the back of the window AC unit.

I can't speak for all, but the ones I had actually had drain plugs on the bottom for cleaning purposes. Installing them required the rear to be 1/2 inch lower than the front and to clean it, the booklet said to use a spray bottle with soapy water to spray down the condensing coil through the vents and from the back, and rinse with low pressure water (book specifically mentioned shower setting) to clean the coils and the condensate tray and to reinstall drain plugs afterwards. Cleaned mine twice a year and they all ran for 10 to 15 years.
Depending where you mount it, the drain should be fitted with a tube to carry the water away where it wont drip- like when fitted above a door. Don't plug the drain hole- thats why you need to flush it out after a while.
They have both. The drain hole is slightly higher than the bottom of the pan so as to leave a little water in the pan, but it will also drain. It does help with efficiency but in the long run it will rot out the condenser coil. I worked on a lot of PTAC units that are glorified window unit and they work the same way.
and that's why the bottom will rust and the unit will smell like mildew and blow that wonderful smell into your lovely room and when the unit is turned off dirt infiltrates the standing condensate and soon becomes mud,
Both of mine are full, I mean freaking full, of rotting mosquitoes right now. It is just grey sludge and smells like complete ass. Horrible, just horrible.
@@HurtsEnd Of course, I have. I'm not stupid! That usually clears it right up, but we've had mosquitos really bad for a prolonged time this year I guess I could try it one more time though?
All that standing water causes that rust on the inside too. Even better is pulling the A/C before winter (just did mine) and dumping a gallon of water all over my interior floor. Genius!!
And I drill mine cuz it slings that rusty water on the condenser making it mucky which makes it hold more water when the ac is off, wonderful air refresher mildew flavored scent after two weeks. Not forgetting a clogged up condenser after 10 weeks.
I've been debating this lately as well. I've known about this engineering design for several years now but recently I'm leaning more towards the opinion that it may be more beneficial to not have a standing pool of nasty water in the unit which accelerates death of the unit due to increased corrosion that typically leads to refrigerant leaks at copper joints in the coils, especially between copper to aluminum coil unions on top of corrosion eating away aluminum fins on the condenser radiator. I haven't researched all the benefits of slinging nasty water over the condenser radiator yet but if it only gains a small amount of temperature efficiency it's definitely not worth it in the long run IMO since it destroys the a/c dramatically faster than running dry. Please, Change my mind...
To be honest though, you shouldn't smell anything coming from the rear part of the unit where the nasty water is being slung since the condenser fan is blowing away to the outside and the inside portion should be sealed well enough to keep the two portions of the unit separate.
15 years carrier units here and go strong ! Water Splash help a lot here (Hermosillo Sonora Mexico 121 Fahrenheit) I put fog/mister on 3 of my split units and the amps draw lows to 11 from 13.5 (24000 btus 220v)
Maybe if you don't take care of it. My rooftop swamp cooler is over 30 years old and still going strong. There's the kind of lifespan you get when you take care of your appliances rather than ignoring them until something breaks.
A great way to collect dust and debris in the water, then plug up the condenser. I have seen some when hooked up for the summer, keep the fan from turning. It also will plug the condenser so bad that it will raise the head pressure to a point where it trips the breaker. So yes, drill the hole. On the second floor it may cause problems with water dripping on the things on the first floor.
@@fashizzlemanizzle4808the pressures wouldn’t even be that high unless you ran the fan on low on a hot day. that water will eventually heat up enough to the point where the added efficiency isn’t worth shortening the life of a unit.
I bet 99% of you didn't know that on the older style a/c units there were drain plugs that in the instructions said to tap it with a punch or small drill bit if it flooded while in slant.
If it dripped evenly all along the top to drizzle down the condensser fins, it could be achieved by collecting water in a bottle and when its filled a pump should push the water above the condenser coil and let it drip, and collect it again,so the cycle could restart imple.ented by new cool water from evaporator,
I use these to spot cool my home...my power bill went from 450 -200 a month...i got a job in the summer of 1971..fixing these...and ive done it every day since...i got 2 to fix today
I have mine drained, including a pipe that runs to a gutter downpipe. What I didn't notice is the inside was full of debris, and water wasn't draining. By the time I realised, there was major unrecoverable rust damage.
I had to drill a hole in mine more towards the middle and angle it pretty good plus screen netting around it to keep the cotton and shit out lol. It would fill with water enough to drip inside
I been doing hvac for 23 years and didn't know this. But it makes sense. I had heard of someone making a device that mists the outdoor unit with water to keep it cool and more efficient on hot days.
You can also see why you should get some of that water out because it produces condensation regardless, a small weep hole is what i would recommend, it still has water flowing to the area it needs but also drains out excess water because it will breed mosquitoes
@@theyreoutthere.huntinggear I have one for my detached garage. It's never been a problem because they cycle. If it's off long enough for larvae to hatch, it probably got cold enough to kill them. They can't survive in temperatures under 50 degrees. The water is condensation from the evaporator coil, so it's going to be cold, too. Whatever the conditions are, it's not an issue. You do need to set them to a very specific level so that only the appropriate amount of water stays in them. They have an overflow weep hole if the level gets too high. The one in the vid may be a little high. Mine is only 110 volts and will freeze you out of the garage on the hottest days. It also doesn't draw enough power for me to notice a difference on my electric bill.
It is a genius design flaw, it makes the machine ROT from the inside. Dry coils equal no mud and the coils will not clog and rot, causing high pressure witch will eventually make the unit spring a refrigerant leak and then WORTHLESS and you go by another. They basically made them disposable. My grandmother has 2 AC’s that are almost 40 yrs old and still run great and they drip enough to water her flowerbeds!!!
These new designs were made due to government energy regulations ,but it is backfiring because these AC's are rotting/rusting/dying in a couple of years which causes people to buy another one which contributes to pollution when the old one go to the garbage dump.
@@starmc26 BS. mold growing in current and previous AC units' blower fan (last I checked fans move pretty fast). constantly damp environment (inside the body of the AC unit) is a catalyst for mold growth especially in climates that are constantly 70-90% humid in the summer. Very little evaporation in those climates and if the stupid thing is designed to hold water in it to begin with, then it never dries out. glad I can save $6 on my electric bill though!!! ...i'll put that in my piggy bank to go towards the hundreds i need to spend when the thing is beyond cleaning every two years.
that sound of the water slinging drove me nuts with mine. drilled a hole in it about 12 years ago and still works great lol I do try to keep the condenser clean and maintain it time to time
Mine is a hotel style a/c unit that hangs out of the wall. It got clogged and started draining inside. So i drilled a few 3/4 inch holes around the pan xD
@@chrishansen5784 problem solved I guarantee. Lol the last hotel I stayed in had one that was running off inside the room. Soaked all my clothes and stuff I had beside of it. I'd say it was the same problem you had
Many people know that water helps cool the hot side when fan hits the water. But the slightly more obscure part is that the water comes from the moisture that was collected on the cold side before being put to use to help efficiency on the hot side.
Many people make things up without knowing what they are talking about :) As an engineer you make me sick. Like why did you just lie? Did you think you werent and where did you get that information? I know you are brain dead but the equation for the efficiency of the Carnot cycle literally is 1- Th/Tc. Since u are stupid that means the bigger the temperature difference, the more efficient. Aka cooling down the hot side lowers the efficiency. They do it to stop water from building up in the system. Have you considered not talking about things you don’t understand?
made that mistake. hit one of the high pressure lines. RIP AC. second came with a plug and since it was in an indoor flex space. couldn't have water flinging around everywhere so had to use the drain port. at least the second one had one.
Doesnt anyone look at the book that comes with them? I guess if you got it used you have a small excuse but the last 3 ive bought said to not drill it, dont remove the plug water stays in it to help it cool.
Embarrassed to say I used to be a "driller". A couple years ago I actually read the installation manual on a window AC. Now my AC is more efficient for sure.
Dude! Thank you for this tip! I was on the brink of buying a new window A/C! 😂 No wonder my A/C was less cold these past few days after I took off a rear drain plug during DIY cleaning and I did not put it back, causing no water to accumulate on the pan for the Slinger Ring to throw to the condenser coils. Charged to experience :)
They also make them air conditioners fail sooner by having them large vent openings so all kinds of dirt, leaves gets inside to clog them up so they don't cool. Then you get mad and purchase another new one. I placed window screen on mine. Now they last longer.
Exactly. It's a good spot that's hard to notice them flying out of but I always wondered where the he'll they were spawing from. Check the Ac unit in the wall and found a mosquitoes paradise.
Yea but what do you do when so much water collects it leaks into the room from the pan? Also the cooler in the front still sometimes creates a leak it’s hot enough outside. But even with a hole drilled enough water still collect to make that slinger effect happen.
@@JahonCross if its cold or rainy/snowy (present/applicable for mehself in my area it does but not coldder than about 20f or hotter than about 120ish degrees so strangely enough fwiw its said still to be a "moderate climate" ) I mean if its a portable unit id just simply take it out of the window or if I had a eother a widnow unit or a first floor need for ac and had both then Id also take that down or fwiw cover it so rain an snow and heaf do escape from back and forth inside to out and vice verse but otherwise as I prefer not to climb a ladder fwiw needlessly.. just not for meh as far as mere fun goes for going up and down and/or getting out a ladder is not meh idea of excitement fwiw idk but yeah Ph also id not want there to be ice an stuff breaking the coils etc from expansion
Some people don't realize some of the big window acs weighing over 150lbs are in Windows 2nd floor and up. Many people have medical/physical disabilities and can't move it. Money can be a issue too for those who say "hire someone".
Smh... You think you're so clever don't you? Some ACs, particularly older ACs, did have drain holes because manufacturers did not realize at the time that it actually could increase the efficiency of the unit by utilizing the cold water that just came off of the cold evaporator coil, in order to help cool the condenser coil. When they realize that, they started to build and design them so that they threw water onto the coil. Now granted, they also didn't think about the rust when they started doing this. But they have been for a little bit now, and newer components are rust resistant or completely rust proof.
@@glasshalfempty1984they definitely are not rust proof. I have seen units completely rusted after just 2 or 3 seasons of use. That on its own is enough reason to drain a hole. The water also causes the coil to get muddy and that will result in high head pressure, which defeats the purpose of the design in the first place.
Mine started overflowing and spitting water out of the control panel. I think my window isn’t angled properly, causing it to flow inwards (140 year old home). I tried and tried to avoid the drill, but eventually was forced to. Where I put the hole still keeps a decent amount of water inside, but it finally prevented overflowing into the house.
The one I have came with a premade drain hole with a rubber plug in it. The manual explained that it collects water and flings it to improve efficiency, but that you can remove the rubber plug if it's a problem.
I live in a humid climate the sling does not drain off enough water. The water starts leaking all over the place. Drilled out a 1in hole added a drain tube now it’s quieter and dry inside
It’s sounds really bad on startup but I’ve serviced quite a few that homeowners drilled holes in the bottom to let the cooling water drain out. Makes the unit overheat and not cool efficiently.
i even modified my ac unit to be fully water cooled i removed the old air cooled condenser and replace it with stainless steel heat exchanger and then modfied the fan to have a water pump that pumps water to the heat exchanger now the room is now colder
Yep, i can confirm they operate longer and more efficiently with the weep hole in the bottom. I bought 2 identical units, put a hole in only one of them. The unit i did not put a hole in didn't make it thru the season, the one i put a weep hole in lasted about 7 years until we finally installed a mini split unit.
I have a portable one and i thought it was quite clever when i saw where the water was hitting it also pooled under the condenser but still drained away
Correct and if it becomes too much water it will drip out the sides there is some kind of a relief somewhere..... So in the big picture you can think of it as having AC coming out of a compressor yet you've also got the idea behind a "Swamp Cooler" keeping things cool for the unit
🌺 Correct & you need to drill a hole under the lowest point of the Air conditioner frame underneath to allow water to either drip or release water from your unit.....😊.......😊.......😊.......
Should unplug yearly and clean with hose, then use a can of A/C coil cleaner on the evaporator. Let set according to directions, then I rinse well. Ready for next season.
AC units have a drain coming from the pan to drain the water away from the house so it doesnt cause rot. The reason the pan gets full of water is because the drain gets clogged. Drill your holes. The fan is not meant to splash splash water.
I moved into an old welding shop for my welding business and the small office had a window unit put in the wall and the side vent openings were totally covered by the wall. I fixed it but I bet the previous occupants could never understand why the AC wasn’t cooling worth a crap.
Whenever I run one that doesn't drain, eventually it will stop cooling. Then you hear the water sloshing on the fan. Then you shut it off to look at it and all the water the air pressure was holding against the coils drops out and soaks the hardwood floor. The never work when they hold water.
They're not meant to hold water, yours will rust out well before it's time if you dont clear the drain. The band around the fan blades helps the fan blow more efficiently and make less fan noise.
Me : someone whoes bro was an engineer, I knew of this condensed water picked by the fan to collect the condenser/ heating coil. Hence, when I grew up and moved to my own home and installed a window air-conditioner and never drained the water to gain efficiency, however I did not realise that product quality have deteriorated since many years AND the result of "my efficiency gain knowledge" was that the botton iron part of condenser and metal frame have all RUSTED 😂
while you can drain it to collect relatively clean drinking water the evaporation off the coils of it further increases your efficiency from the byproduct of it's function of creating temperature differentials

@@HurtsEnd Of course, I have. I'm not stupid! That usually clears it right up, but we've had mosquitos really bad for a prolonged time this year I guess I could try it one more time though?
All that standing water causes that rust on the inside too. Even better is pulling the A/C before winter (just did mine) and dumping a gallon of water all over my interior floor. Genius!!
If you were smart you would get some gauze and stick it right in the back end of it and allow it to drain the water.
Youre right, i always opened up the drain hole as i thought water was a bad thing
And I drill mine cuz it slings that rusty water on the condenser making it mucky which makes it hold more water when the ac is off, wonderful air refresher mildew flavored scent after two weeks. Not forgetting a clogged up condenser after 10 weeks.
I'm with you, I've seen too much rust and gunk to NOT drain that water.
@@topknotsrule same
I've been debating this lately as well.
I've known about this engineering design for several years now but recently I'm leaning more towards the opinion that it may be more beneficial to not have a standing pool of nasty water in the unit which accelerates death of the unit due to increased corrosion that typically leads to refrigerant leaks at copper joints in the coils, especially between copper to aluminum coil unions on top of corrosion eating away aluminum fins on the condenser radiator.
I haven't researched all the benefits of slinging nasty water over the condenser radiator yet but if it only gains a small amount of temperature efficiency it's definitely not worth it in the long run IMO since it destroys the a/c dramatically faster than running dry.
Please, Change my mind...
To be honest though, you shouldn't smell anything coming from the rear part of the unit where the nasty water is being slung since the condenser fan is blowing away to the outside and the inside portion should be sealed well enough to keep the two portions of the unit separate.
@@eds6569 About half of the window units out there have fresh air dampers that draw outside air from the slimy, mildew, condenser water compartment.
It may save you power, but you'll need to replace the ac sooner as it will cause the condenser to rust out.
I have never replaced an ac unit in any rental houses or my own bc of a rusted condenser unit....just my experience
I have had them rust out
15 years carrier units here and go strong ! Water Splash help a lot here (Hermosillo Sonora Mexico 121 Fahrenheit) I put fog/mister on 3 of my split units and the amps draw lows to 11 from 13.5 (24000 btus 220v)
@@charliebrownn6622 Works in Sonora because the climate is dry.
Maybe if you don't take care of it. My rooftop swamp cooler is over 30 years old and still going strong. There's the kind of lifespan you get when you take care of your appliances rather than ignoring them until something breaks.
A great way to collect dust and debris in the water, then plug up the condenser. I have seen some when hooked up for the summer, keep the fan from turning. It also will plug the condenser so bad that it will raise the head pressure to a point where it trips the breaker. So yes, drill the hole. On the second floor it may cause problems with water dripping on the things on the first floor.
Its supposed to drain out the condensation that's why some have a drain hose...it will get mold and stink..
Wrong. It’s using the condensate to lower pressure in the condensing unit. Did watch the video?
@@fashizzlemanizzle4808the pressures wouldn’t even be that high unless you ran the fan on low on a hot day. that water will eventually heat up enough to the point where the added efficiency isn’t worth shortening the life of a unit.
I bet 99% of you didn't know that on the older style a/c units there were drain plugs that in the instructions said to tap it with a punch or small drill bit if it flooded while in slant.
I thought just about everyone knew. Mine has a drain plug and it's covered in the instructions.
It makes a nasty smell, best to vent the bottom before installing
I'm literally hearing my window a/c now lol. Best asmr for summertime sleep
But the crickets sound better
Evaporative cooling y’all it’s how the human body cools itself!! Water on the coils definitely helps ac efficiency
Correct. a comment from someone who knows their stuff! 👍🏼
If it dripped evenly all along the top to drizzle down the condensser fins, it could be achieved by collecting water in a bottle and when its filled a pump should push the water above the condenser coil and let it drip, and collect it again,so the cycle could restart imple.ented by new cool water from evaporator,
A company also invented a water treatment that turns this watr into a drink water fountain
It will ruin the fins. A coating of hard water crud will build up over time. There is a reason you don't see this on whole house ACs
I’ve always wondered what that liquid sound was.
I use these to spot cool my home...my power bill went from 450 -200 a month...i got a job in the summer of 1971..fixing these...and ive done it every day since...i got 2 to fix today
I have mine drained, including a pipe that runs to a gutter downpipe. What I didn't notice is the inside was full of debris, and water wasn't draining. By the time I realised, there was major unrecoverable rust damage.
yup, gotta do a deep clean on them once in a while.
I did ! Am a 30yr.retired HVAC tech. Thanks !
👍🏼 thanks for the input
😂😂😂
QUESTION.... If that right then why when it rains does that slinger ring causes the fan to blow water inside my house and soak my floor???😮
Drill gang here, was tired of it sounding like a running toilet, 4th season and still running strong.
I’ve drilled them in the past 👍🏼
I had to drill a hole in mine more towards the middle and angle it pretty good plus screen netting around it to keep the cotton and shit out lol. It would fill with water enough to drip inside
I been doing hvac for 23 years and didn't know this. But it makes sense. I had heard of someone making a device that mists the outdoor unit with water to keep it cool and more efficient on hot days.
I always drill them out as I'd rather the water drain then rot the machine
@@Farquad76.547 yeah😂 so it'll rust out and you have to buy a new one sooner. it's called planned obsolescence
@@oliver_klozoff nailed it
Fans there that’s cooling it.
It’s that way so it rots and you buy more
Lol my 10 year old one that I even dropped from the second floor window running none stop every spring and summer would disagree with rotting...
A buddy of mine , who's a HVAC tech, said when really hot, put a small sprinkler near your whole house AC unit. Helps transfer heat.
Yup, it's the same design 👍🏼
The only problem is - you'll end up with mineral build up on the condenser in the long term.
So the water would need to be filtered.
@@havanasyndrome3024 Great point❗️
You can also see why you should get some of that water out because it produces condensation regardless, a small weep hole is what i would recommend, it still has water flowing to the area it needs but also drains out excess water because it will breed mosquitoes
Mosquitoes need still water
@chrisbrooks6697 yea. No weep hole and it's stagnant and when you turn if off , that's when they start to breed
@@theyreoutthere.huntinggear I have one for my detached garage. It's never been a problem because they cycle. If it's off long enough for larvae to hatch, it probably got cold enough to kill them. They can't survive in temperatures under 50 degrees. The water is condensation from the evaporator coil, so it's going to be cold, too. Whatever the conditions are, it's not an issue. You do need to set them to a very specific level so that only the appropriate amount of water stays in them. They have an overflow weep hole if the level gets too high. The one in the vid may be a little high. Mine is only 110 volts and will freeze you out of the garage on the hottest days. It also doesn't draw enough power for me to notice a difference on my electric bill.
I did not know that😳. I actually drilled holes in one once to drain the water .😮
Lol
I used to think it was a bad design / defect too. ‘Salright.
CAULK THEM!
It is a genius design flaw, it makes the machine ROT from the inside. Dry coils equal no mud and the coils will not clog and rot, causing high pressure witch will eventually make the unit spring a refrigerant leak and then WORTHLESS and you go by another. They basically made them disposable. My grandmother has 2 AC’s that are almost 40 yrs old and still run great and they drip enough to water her flowerbeds!!!
Hopefully at the back of the unit. They have over flows out the back...
Designed to not to last…rust. Class Action
These new designs were made due to government energy regulations ,but it is backfiring because these AC's are rotting/rusting/dying in a couple of years which causes people to buy another one which contributes to pollution when the old one go to the garbage dump.
@rainerrain9689 No ac unit should ever rust in anything critical for use unless it isn't installed correctly
Excellent design for keeping it nice and moldy too!
Lol, the water is constantly moving, and evaporating.. mold can't grow.
@@starmc26 BS. mold growing in current and previous AC units' blower fan (last I checked fans move pretty fast). constantly damp environment (inside the body of the AC unit) is a catalyst for mold growth especially in climates that are constantly 70-90% humid in the summer. Very little evaporation in those climates and if the stupid thing is designed to hold water in it to begin with, then it never dries out. glad I can save $6 on my electric bill though!!! ...i'll put that in my piggy bank to go towards the hundreds i need to spend when the thing is beyond cleaning every two years.

It's supposed to be installed pitched away from the room/window sill
Supposed to drop a quarter inch from front to back
Yes but that water causes rust. My A/C has been doing that lately even making a different noise but felt tiny spits of water from it.
Many people know that water helps cool the hot side when fan hits the water. But the slightly more obscure part is that the water comes from the moisture that was collected on the cold side before being put to use to help efficiency on the hot side.
Many people make things up without knowing what they are talking about :) As an engineer you make me sick. Like why did you just lie? Did you think you werent and where did you get that information? I know you are brain dead but the equation for the efficiency of the Carnot cycle literally is 1- Th/Tc. Since u are stupid that means the bigger the temperature difference, the more efficient. Aka cooling down the hot side lowers the efficiency. They do it to stop water from building up in the system. Have you considered not talking about things you don’t understand?
made that mistake. hit one of the high pressure lines. RIP AC. second came with a plug and since it was in an indoor flex space. couldn't have water flinging around everywhere so had to use the drain port. at least the second one had one.
Doesnt anyone look at the book that comes with them? I guess if you got it used you have a small excuse but the last 3 ive bought said to not drill it, dont remove the plug water stays in it to help it cool.
Embarrassed to say I used to be a "driller". A couple years ago I actually read the installation manual on a window AC. Now my AC is more efficient for sure.
Dude! Thank you for this tip! I was on the brink of buying a new window A/C! 😂
No wonder my A/C was less cold these past few days after I took off a rear drain plug during DIY cleaning and I did not put it back, causing no water to accumulate on the pan for the Slinger Ring to throw to the condenser coils. Charged to experience :)
Glad to help! Yeah, I just learned that too a few years ago, kind of cool engineering 👍🏼
They also make them air conditioners fail sooner by having them large vent openings so all kinds of dirt, leaves gets inside to clog them up so they don't cool. Then you get mad and purchase another new one. I placed window screen on mine. Now they last longer.
Drill it. Friggin gurgling will drive you crazy 🤣
You think you can hear it over the compressor? Cause you cant

Exactly. It's a good spot that's hard to notice them flying out of but I always wondered where the he'll they were spawing from. Check the Ac unit in the wall and found a mosquitoes paradise.
Yea but what do you do when so much water collects it leaks into the room from the pan? Also the cooler in the front still sometimes creates a leak it’s hot enough outside. But even with a hole drilled enough water still collect to make that slinger effect happen.
Drill it.. Your efficiency will drop once all the nasty water slinging on the condenser turns into a hard mat of crap blocking airflow.
my dad drilled a hole through the damn condenser
I drilled a hole through the freon pipe. So sad but I got pretty high
@@raysure1345 it's not called a Freon pipe

@@LuisLopezActive what ?
Nice video tutorial. But what about mold build up from the standing water when not in use?
Why wouldn't they contain the water better if it was for that? Pretty sure it would be a plastic pan if this was meant to hold water.
Then it wouldn't rust out. And you wouldn't have to go buy a new one. Gotta keep the economy rolling lol
Some window units have part of the condenser coil at the bottom of the unit to help reject heat and evaporates the water causing a dripless unit
That’s genius!
I have two dripless units in my rental right now. I will never buy anything else.
That would be nice. My neighbors window AC upstairs drips right on top of my AC. Gonna have to do something about that for next year
@@jessefoulk Same problem here. I got a galvanized sheet of metal and slid it under the upstairs unit to divert the drip further out from my unit.

NO WAY! I swear these phones read your mind. I was just thinking of doing this
Spooky
If you could arrange a waterspray/mister aimed at the coils of your outside AC unit , would it improve efficiency , especially on super hot days ?
I like the hole that is at the back of my AC. Straight from the factory. Guess they didn't know that.
Smh... You think you're so clever don't you? Some ACs, particularly older ACs, did have drain holes because manufacturers did not realize at the time that it actually could increase the efficiency of the unit by utilizing the cold water that just came off of the cold evaporator coil, in order to help cool the condenser coil. When they realize that, they started to build and design them so that they threw water onto the coil. Now granted, they also didn't think about the rust when they started doing this. But they have been for a little bit now, and newer components are rust resistant or completely rust proof.
@@glasshalfempty1984they definitely are not rust proof. I have seen units completely rusted after just 2 or 3 seasons of use. That on its own is enough reason to drain a hole. The water also causes the coil to get muddy and that will result in high head pressure, which defeats the purpose of the design in the first place.
Bacteria paradise
Yep Legionnaires disease at play right there

@@xXSasukeXx89 it’s called legionnaires disease, caused by bacteria it is common in air conditioning and cooling towers . It kills a few people a year
Mine started overflowing and spitting water out of the control panel. I think my window isn’t angled properly, causing it to flow inwards (140 year old home). I tried and tried to avoid the drill, but eventually was forced to. Where I put the hole still keeps a decent amount of water inside, but it finally prevented overflowing into the house.
What if that water is going right into my floor? I pulled a rubber insert and it hasn't done it since.
Hmm… How old is your unit? Definitely, water shouldn’t be coming into your room!
It's supposed to be tilted a bit so the water runs toward the outside
Yes helps transfer heat! I'm in the 1% 😆
The one I have came with a premade drain hole with a rubber plug in it. The manual explained that it collects water and flings it to improve efficiency, but that you can remove the rubber plug if it's a problem.
Right before you go to bed, go outside and spray that condenser coil with the hose. Cold is sleep you'll ever have 😊
Good tip! 😴
You answered so many questions. Thank you. 😊
I live in a humid climate the sling does not drain off enough water. The water starts leaking all over the place. Drilled out a 1in hole added a drain tube now it’s quieter and dry inside
Some units require a specified pitch, some require to be level.
1% er here..... Also a refrigeration and AC mechanic lol
It’s sounds really bad on startup but I’ve serviced quite a few that homeowners drilled holes in the bottom to let the cooling water drain out. Makes the unit overheat and not cool efficiently.
i even modified my ac unit to be fully water cooled i removed the old air cooled condenser and replace it with stainless steel heat exchanger and then modfied the fan to have a water pump that pumps water to the heat exchanger now the room is now colder
Yep, i can confirm they operate longer and more efficiently with the weep hole in the bottom. I bought 2 identical units, put a hole in only one of them. The unit i did not put a hole in didn't make it thru the season, the one i put a weep hole in lasted about 7 years until we finally installed a mini split unit.
Welp looks like I need a new one 😂😂🤦♂️
Should’ve came across this yesterday morning 😂
haha no problem, it still works fine, just slightly more inefficient!
Plug the hole was never an option. Boat sank
I have a portable one and i thought it was quite clever when i saw where the water was hitting it also pooled under the condenser but still drained away
DO NOT DO THIS WITHOUT CAUTION!!!!
if you over drill youll hit the freon
Drill only in the drain, ideally pull it out first so you can see - they have a drain tray, put a heavy handed drill could go through the condenser.
Laying with mine on now. Ahhh, ice cold air to help me sleep.
Correct and if it becomes too much water it will drip out the sides there is some kind of a relief somewhere..... So in the big picture you can think of it as having AC coming out of a compressor yet you've also got the idea behind a "Swamp Cooler" keeping things cool for the unit
Is that why I have nats coming in my room?
Do they look like blsc2k. Triangle shaped flies? Drain flies from nasty sitting water.
🌺 Correct & you need to drill a hole under the lowest point of the Air conditioner frame underneath to allow water to either drip or release water from your unit.....😊.......😊.......😊.......
The whole unit is covered with rust
you could use an A/C as a heat pump. revers cycle it Use in the midle easte for heating in the winter (in Baghdad)
Love seeing them on the trash pile because someone drilled a drain hole and punctured the coil.
😂😂 soo many have commented saying they’ve done this. Even I drilled into the fan once
ok going to plug the holes i made hahahaha
Should unplug yearly and clean with hose, then use a can of A/C coil cleaner on the evaporator. Let set according to directions, then I rinse well. Ready for next season.
Until you drill into the condenser 🤣 I've replaced a few for friends lol
Who drilled the pan?
👇
Put the drill down ?? How do you get it to stop leaking inside the house?
I knew it, I just don't want the bottom of my AC to rust out so it drains instead!!..😉
I drain mine to ;)
AC units have a drain coming from the pan to drain the water away from the house so it doesnt cause rot. The reason the pan gets full of water is because the drain gets clogged. Drill your holes. The fan is not meant to splash splash water.
Ikr this dumb ass just making up shit why does it say in manual to place unit at a slope to allow water to drain...
👏🏾👏🏾👏🏾👏🏾👌🏾
I moved into an old welding shop for my welding business and the small office had a window unit put in the wall and the side vent openings were totally covered by the wall. I fixed it but I bet the previous occupants could never understand why the AC wasn’t cooling worth a crap.
For all you leftist and Yankees movin on down to the dirty south, this is your life. Hard work and hard times. Enjoy. and Bless yer hearts.
Don't challenge them...shit, they'll do it. Just what we needed.
What does it mean when the water starts coming out the front had it happen. Through the fan it threw a mist not leaking on floor
Whenever I run one that doesn't drain, eventually it will stop cooling. Then you hear the water sloshing on the fan. Then you shut it off to look at it and all the water the air pressure was holding against the coils drops out and soaks the hardwood floor. The never work when they hold water.
They're not meant to hold water, yours will rust out well before it's time if you dont clear the drain. The band around the fan blades helps the fan blow more efficiently and make less fan noise.
Me : someone whoes bro was an engineer, I knew of this condensed water picked by the fan to collect the condenser/ heating coil.
Hence, when I grew up and moved to my own home and installed a window air-conditioner and never drained the water to gain efficiency, however I did not realise that product quality have deteriorated since many years AND the result of "my efficiency gain knowledge" was that the botton iron part of condenser and metal frame have all RUSTED 😂
while you can drain it to collect relatively clean drinking water the evaporation off the coils of it further increases your efficiency from the byproduct of it's function of creating temperature differentials
If that’s the case . Make it cleanable so it doesn’t rot out the whole unit . Or is that by design ?
I did know it because I used to sell them!!😊
