What if I don’t have a way on making a whole in the garage? Can I still install it? I have a small 12ft x 9ft x 9ft room inside the garage and that room is close down. I want to have it with AC but I don’t have a way on making a whole to use the hose the portable ac brings. Please if anybody got any tips! @DoItYourselfDad

[@FRUGALWITHJOHN]

Never ever buy a single hose air conditioner for a garage, unless you need an air exchanger. All the air being pushed out of that single hose will need to be replaced, it will come in every pin hole you have in the garage. Put your hand around your your garage door and you will feel it. Plus all that cold air you just paid for is being grabbed again and pushed outside. Get a double hose or a mini split. Even a 5000BTU window unit will work 100% better than your 8000BTU single hose and use less power, for only be around $100.

[@3sidesofeve711]

Agreed, This are the worst models to buy for any application.

[@joegreen7616]

Can you recommend a double hose ac…thank you.

[@prod_xen]

@Tommy Ealey single hose air cons only have that "single hose" to remove the hot air in the area you are in, but it's also creating a vacuum over time because its pulling not just the hot air, unlike dual hose or twin hose, there's one hose for air intake, and another hose for the exhaust air(hot air)

[@cllewis1]

@Tommy Ealey single hose means it has only an exhaust pipe. You can get these that have 2 pipes- one for intake and once y for exhaust, so you aren't dumping the air from the conditioned space outside.

[@OhPhuckYou]

I can't imagine a 5K BTU unit doing a thing in my garage. Haha Bout like farting into a hurricane. It would drop humidity and maybe drop temps from 115 to 100, if that.

[@dondieu3154]

When you say swamp coolers are good for Texas, you should mention WEST Texas, not all of Texas. Most of Eastern Texas has high humidity, so a swamp cooler will just not work well.

[@tomj528]

Nice setup. I went with a 12,000BTU 120V window AC unit that I install every spring in the awning window on the south side of my garage which is under a 2' overhang so it doesn't get rained on or sun bleached. I remove the sash, molding that holds the screen (screws) and the mechanism before installing a board along the top then slide the unit in place, extend the wings and screw the unit in place to the board I installed along the top. I live in the upper Midwest and the summers are hot and humid so this is a much better solution for me. The unit was around $350 but that was about 25 years ago so I've more than gotten my use out of the thing. Cheers!

❤ I really am a basket case overwhelmed with so many emotions and totally exhausted trying to articulate this at 4 am without it becoming a novel. (Not looking good so far lol) Just like you. I go to KZbin all the time for all these projects. And I wonder what it would have been like to do all of those projects around the house growing up with my father. Should we have had The same technology? My father was An accountant. grew up in Brooklyn, New York, so he was A city boy, but at the same time of the old world. I mean, he literally grew up across the street from the horse stables in Brooklyn. If that can give you some perspective. Most likely if you did work with your hands. It's it probably had more to do withe mafia. Or helping things fall off of The truck. Anyways, getting to the point. He was very good with numbers. When I was born we had a house in new jersey with a quarter acre lot. When he went to fix things he just would use common sense which works and you know 85% of the time. So you would learn from your neighbors. Or you would learn from the people at the hardware stores. Or sometimes you would learn the hard way, and after paying the professionals to come fix your botched job we would watch what he did for next time. Really none of that mattered cause it was funny making 13 trips back to the store. Cause we messed something up. Or Just getting a good laugh after realizing. We installed something upside down or whatever it was. We had a lot of fun!🥲 "Hey Franky can you give me a hand real quick?" "How long is real quick?" "It's a 5 minute job!" That became the classic quote in our family.❤ I was the youngest of 4 boys. Now a father of 2 girls, I still don't know what I'm doing as much as I convince myself that I do. You really just made me so aware of a really really big pill to swallow that I haven't been searching for answers for fixing my water heater or how to install a tiled backsplash. I miss having someone to do it with.....my Father. My wife and girls not interested, both my brothers are jersey. So i Pour my dysfunctional heart out to youtube. 🤷‍♂️👍✌️🖖🏻 So thanks! I feel a lot better😊 Sending positive thoughts and energy your way AlexaaCapella!🖖🏻☯️ (A year out of sync lol)

[@mikeslater6246]

Single hose portable air conditioners do have their applications but they are highly limited and very specialized or for emergency use. They are good for putting cool air in a specific place in a room when you're not trying to cool the whole room. The KZbinr said very plainly he discharges the cooled air straight at where he's working. You don't have to cool the whole room if you've got cold air blowing directly on you.

[@gofasters1]

Thx for the video. I'm in southern Utah with hot summers and it's 114 degrees today. I'm gonna look for a 14,000 BTU. Thx again

[@Andy-df5fj]

You'd get more mileage out of that 8,000 btu portable if you had the hot side intake draw in outside air instead of from the inside of the garage. The problem with the unmodified single hose design is that as you expell the hot air, it creates a vacuum that draws in hot outside air from all the cracks and crevices of the garage, greatly reducing the overall cooling power of the unit.

[@DoItYourselfDad]

I’m in the process of converting a larger single hose to a dual right now. Will hopefully have a video up on it soon.

[@Andy-df5fj]

@@DoItYourselfDad Good luck. I think it will help greatly.

[@sferg9582]

Yes. That's the same effect you get from running your clothes dryer where you're pumping a lot of air outside but nothing is being supplied to the dryer in the form of "make-up air". Most modern furnaces will have an outside air supply that goes only to the burners so they're not blowing conditioned air outside.

[@keithbroughton4476]

Agreed! I have used the "portable" type before and the problem you outline does reduce the efficiency. There are portables with both intake and exhaust hoses. For my garage, I just installed a typical (8000BTU)vertical window unit and it works very well.

[@johne1460]

That garage vent thing must be a southwest thing. Lived in the upper Midwest and never seen that.

Excellent idea. Will be installing ASAP. Live in Hot Springs, AR. And when they say hot they mean hot.

[@mdvener]

I live in s/w fla. My air handler in my 2 1/2 car garage. On the supply side I installed a 4" supply grill. NO RETURN LINE. SUPPLY ONLY. During the day I will open the vents, then close it at night. Outside temp is in the 90's. My garage it is 80 degrees and25% humidity. About 10.00 for the vent.never noticed hardly anything on the electric bill. Been doing it for 15 + years. My system never sweats. My neighbors air handlers sweat. Working outside in this fl. heat, it really is refreshing coming into the garage.

[@fredflintstone8048]

The better models of portable AC units are 'dual hose' which not only exhaust the warm air off the condenser to the outside, but also draw the intake air for the condenser from outside. The single hose units will draw the hot outside air inside the very space you're trying to cool to make up for the condenser air exhaust any way it can. It's more efficient and you'll get better cooling / heating (heat pump) results with the two hose systems. Yes, they cost more. If you have or acquire a single hose unit it would be good to try and get creative and rig up an intake hose for the condenser. On the single hose units the condenser input tends to be a different grill input on the unit than the evaporator input. The problem with those portable evaporative coolers is that the humidity from the evaporative cooling process remains in the space you're trying to cool which in a short amount of time will raise the overall humidity in the space not only rendering the evap cooler less effective, will make the space more uncomfortable because our skin which is our own evap cooling system stops working. If I were to consider evaporative cooling for my shop I would get a real one that goes outside the building, and forget the ones that go inside. The lower humidity warm air from outside will be more effective for cooling. Just remember if you have a monsoon season or any other season where the humidity levels are high, they're totally ineffective, and if anything make you more miserable because they ALWAYS increase your humidity levels. I for one cannot use evap cooling because I have metal and wood working machines, lathe, milling machine, drill press, table saws etc and when your humidity level starts going above 50% you're looking at rust forming on bare metal surfaces. Insulating is very critical as was pointed out. Think of the space like a bucket with a hole in it that you're trying to fill. You're trying to get rid of the heat faster than it's coming into the building. The better the ratio, the more comfortable it's going to be and the less energy you'll spend on conditioning the space.

May i ask? What system do you have for your garage? I have machines and tools for woodworking too.

[@PROJECT.LUKE.ONE.75]

You'll want a mini split in there for sure. For heating and cooling.

[@wardrobelion]

The door is the biggest issue, especially if it faces south. Insulation or even styrofoam on the door panels. Even just shading that door or spray it with a hose at hottest point of day for the door…even just drape a blanket over it or if affordable, a large area rug or two. And a way to exhaust heat. A hole the size of dryer hose up high would work with a small fan exhausting out too. Any way you can provide shade to it would help tremendously. A trellis with vines works well too. Mulberry trees are fast growing, provide shade and fruit and can be kept pruned so you can access the abundant berries, not to mention, you could burn the wood in the winter if needed or grilling in summer. Have fun and think small. Dash and Nostalgia both have mini appliances that use under 500W so even a power box would run them. I, personally, would only buy a portable a/c if I needed to move it from room to room. They tend to get really hot causing more heat from the motors and the ducts need extra insulation because the exhaust is really hot too. A window unit is most efficient, even if you have to remove or cut a panel in the door…those portable units are like 10 to 12 thou btu’s too. A ceiling fan even would help…I cut the cord off of mine and wired a 12gauge extension reel cord to it that had a bad outlet. I just cut off the cord. We mounted it on the ceiling but have it plugged in to the wall so no hard wiring anything. It’s been up and running perfectly for almost 10 years now👍. Plus I can move it if I want. They use very little power too. Enjoy your life and remember it’s an adventure…

Great advice for cooling a garage! I have a 2 1/2 car garage (24' x 22' or 528 sq). As a car detailer in Illinois, the summer months are humid and the temps inside garage can exceed 100 degrees. I don't have regular windows that will accommodate a window air conditioner, but have a floor drain that drains out to the outside in the back of the garage under the concrete. Would it be possible to get a portable AC and run the hose to the floor drain as a vent?

[@DoItYourselfDad]

I would think it would be fine as long as there wasn’t restriction in the floor drain, so you had clear flowing air.

[@1AXMRDR]

I have the same model and it does not keep up with my garage. It's basically a 3 car garage with 2 doors. I needed something quick and easy at the time but like others have mentioned the 'make up' air that this thing blows out ends up coming in from every small opening around the garage door. Bite the bullet and get a mini split. I have since installed a package unit heat pump in my shop so I don't use the garage much anymore in extreme weather. I have this unit sitting on my workbench blowing exhaust out a window so I didn't have to cut any holes. Ceiling fans help as well. They also help dry the rain water that runs from the cars when parked.

[@robh3267]

Evaporative (swamp) coolers only work if the unit is mounted on the exterior of the building preferably in the sun so it can evaporate the moisture from the air which also helps to keep a fresh cool continuous supply of water going into the unit, those indoor swamp coolers don't really work they usually just make a room more humid without actually cooling the air at all, for a garage anything over 10,000 BTU like a window AC would do a better job and you can find those used for cheap also.

[@guitaryst]

I have a 12000BTU unit and it blasts cool air into the garage, but the temperature really does not lower in the garage. 2 car garage in AZ at 12000BTU. I am not sure what is going on. How cool is your garage? You do not mention it in the video.

[@eugeneplakosh8423]

All looks really good. The only flaw I can see is the air exaust hosing. If you look at the instructions you willsee that they recommend that you NEVER vent it below the machine. Reason beingis that hot air rises. and you get hot aair backed up into the unit cutting its efficincy rating way down. I have been using these formany years, I will say I'm switchingback towindow or wall units. The portables work exellent innormal heat, but when you start getting into extreme heat is when they crap out. I always buy the top of the line units, and it is always the same.

One bad thing about that style is it makes the room negiteve press you are drawing hot air from outside to replace the air it uses to cool condensing coil.

[@DoItYourselfDad]

You’re definitely right about that, not sure why these things don’t have an intake hose as well. Fortunately it cools more air than a displaces, but it would be a lot more efficient if I had an intake hose that came from the outside for the air but it’s using to cool the condensing coil.

[@tslucam]

[@Simple5.0]

We have a sort of small 2 car garage but the ceilings are really high. Do you think 2 of these would cool a 2 car garage with an 18’ ceiling?

Some portable A/C units have the condensate line integrated into the exaust hose.

Most use a water "slinger" to throw the water up into the air flow into the condenser, helping to cool the condenser and vaporizing the water to be sent out the exhaust hose.

[@adamdelarozza1985]

[@NeverEnoughPyro40]

And you are the reason why professionals dislike DIYers! Plumbing your homes central HVAC into your garage is not only a horrible idea but dangerous, Oh and not to mention against all Codes! I’m not sure if I understand your comment correctly because you are not using the correct Termanology! Did you install a vent fan into the supply side or return side of your HVAC? Either way I am pretty sure that whatever you did could not only be dangerous but against Code!

[@adamosity7127]

Of course it's against code. :) It attaches to supply line. When centrifugal 850CFM fan is not running a motorized damper closes automatically. I also added an exhaust vent from garage in to attic which is cross ventilated (slit slats on both ends of A frame). The damper is not a perfect seal. A little bit slips by when HVAC is on to keep pipes from freezing in winter and push heat from car engine out in summer. I live in Texas. Washer and electric dryer are in garage. My setup was about $250. I appreciate your passion. The code was written for the brilliant folks that warm their cars in the garage in the bitter cold north and the people that do not have sense to open their garage door when their car is running. When the attic fan runs it does put a huge drain on rest of house but not to point of misery. In the spring and fall, we turn the attic fan on and HVAC off on low wind nights. The efficiency lost in winter and summer is made up in spring and fall. There is greater risk of carbon monoxide from my furnace than the garage. We also plan to keep an electric car in the garage and our dinosaur in the driveway.

[@mikeanonymous669]

You described the way the heat pump works wrong. It absorbs heat from the outside and then releases that heat into the garage (in your case). Cold air is just air with the absence of heat. You can add heat to air but you cant add cold to air. In cooling mode the unit absorbs heat from the air in your garage and transfers it to the outside via the pipe. There is a refrigeration cycle to do all that but I wont get into the weeds here. A heat pump is an air conditioner running backwards and the way that is possible is by a reversing valve that changes the direction of the refrigerant in the cycle.

[@DoItYourselfDad]

Didn't do too well in physics I see.....

[@mikeanonymous669]

@@DoItYourselfDad State your claim. I have a EPA 608 Universal card and am licensed to service A/C units. I did "dumb down" the explanation to keep from getting to technical but you were outright wrong in your description. When running in cool mode the evaporator absorbs heat and then it is transported via the refrigerant to the the condenser where it is rejected to the atmosphere by a fan that blows it out your exhaust pipe (for a portable unit like yours). In heat pump mode the reversing valve changes the direction of the refrigerant and makes your evaporator the condenser and the condenser your evaporator. The air is drawn in from the outside and the heat is absorbed at the evaporator and then transferred via the refrigerant to your condenser (was your evaporator in cool mode) and the heat is rejected to the garage space via the blower fan across the condenser (was your evaporator in cool mode). Again, I say.... State your claim.

Or the third and really only smart / logical option is to frame in a window unit in a wall at about 6.5’ off the floor. So you are pulling hot air from the high point within the to be conditioned space. Because we all know air conditioning doesn’t work by putting cold air onto desired area ! But, by taking hot air out of the desired area ! And what does hot air do ? It rises, in fact the more cold air you put into a space the more the cold air holds the hot air up high. Special note - generally the formula is - 12,000 cooling btu per 550 / 600 sq ft. But for a window unit to work efficiently / properly ? Double the btu. A 35 year licensed HVAC C-20 contractor. ✌🏻

[@DoItYourselfDad]

A window unit would definitely be better, unfortunately with where all the shelves are in my garage, it wasn’t an option.

[@RedHammerBodyShop]

A mini split stomps a window unit to death. And are basically silent, and only about 500 bucks for a 12,000 btu and doesn't look like a trailer house special. Lol

[@gregie9999hotair1]

If that's the case 1 foot off the ceiling, it would cool all that heat up near the ceiling and spread cool air from above.

I’m pretty sure the one way valve in a dryer vent is a fire code violation as the damper/flapper can cause lint to build up ..

Great explanation, 👍🏻 👌🏻 thank you for making the video

[@grayrabbit2211]

Eh.. I'm glad it works for you but these portable units, especially single tube ones are useless in Florida. The smallest, cheapest window AC will outperform them. I have a Sharp single tube portable AC and all it ends up doing is pulling hot humid air from all of the cracks and openings in the house. It may get a few degrees (like 3-4) in the room it's in but the higher humidity makes it feel more uncomfortable than before. One bonus on the Sharp over the others is that it has a built in condensate pump and pumps the condensate from its internal tank over the condensing coil, which evaporates the water and sends the water vapor right out the exhaust tube. I've never had it's internal tank get full.

[@hgw90026]

A portable air conditioner should have in intake and exhaust hose in the back. With a single exhaust host, all the hot air going out needs to be replaced by the same amount of warm/hot outside air. With a swam cooler, the intake air must be fresh dry air from the outside. Having it sit in the middle of the room will just circulate the increasing humid air thus minimizing its evaporative potential and cooling.

[@stevey500]

This is the most important comment on this whole video. A single tube unit shouldn't EVER be used. Single hose units are only good for very temporary spot cooling, that is it. A dual hose unit is absolutely ideal if you want real and efficient results.

Finally, someone that lives in the desert like me, I'm listening.🤔

[@bennywilks9367]

An evaporative cooler needs a source for the dry warm air that it is cooling to furnish cool moist air into the living space. If one just places it in a room, after it cools the air a certain amount, it will start taking in moist air and it will not work.

[@RESOURCECONTROLLER]

It was so noisy with and was so noisy with the fan. The mobile fan in the air conditioning running. And I didn't realize I had left the bathroom fan on So when I woke up, the house was so much cooler. Now this bathroom fan is. Directly in front of the garage door in the garage door from the dog scratching as a the padding has been scratched off the door Near the dog height. So an acting as pulling air. In while sucking air out causing air conditioning effect. Really cool and it works really works. Energy Efficiency: Running the fan intermittently (e.g., 20 minutes every hour) minimizes energy consumption compared to continuous operation while still providing some level of ventilation.

However, homes have a limit to how much heat they can store before reaching equilibrium with outdoor temperatures. This means that even after several hours of being off, you may not need to remove as much heat as expected when you turn it back on.

Single hose portable ACs are terrible because by creating negative pressure in the room the operate in they cause air to be sucked in from the outside which makes them very inefficient (compared to a regular AC which circulates the inside air). In humid locales it’s even worse because along with outside air they also bring in outside moisture.

[@colemandeitz7302]

Take the condensate line and run it in the drain line line by your washing machine

[@mrgoats]

Air conditioners do not need vents. Most have heat exchangers. Vents are a really bad use of electricity. They are constantly having to recool new air instead of using existing cool air. You also wont be reducing the humidity has the new air needs to be pulled from somewhere and that somewhere is outside.

[@elonmusk8667]

I would lift the AC unit as high as possible since cool air falls Then I would insulate the garage and attic space.

[@DoItYourselfDad]

Agreed, I got it as high as possible, but higher would have been better. I insulated the roof with radiant barrier as well as the garage door with foam, both made a huge difference.

[@peterpowers4851]

What do you do about the negative air pressure?

[@aestheticlife5380]

Does it really work for very hot garages?

[@DoItYourselfDad]

Yes, it does. Be sure in insulate first though!

[@Nirotix]

As a J-man Sheet Metal Worker I was jusr about to hate on you until you mentioned dealing with 'condesation'. I'm not cool with R2D2's. Yes, they have their place. In a garage setting, I'ld simply use fans. But that is me, I have mostly metal equipment.

[@DoItYourselfDad]

Fans are only so good, it was 115f today. Fans aren’t going to do a thing to make that miserable.

[@johnmiddleton726]

I was very interested in the garage insulation video. I was pricing out that reflective video at Lowe’s when I noticed some budget friendly foam panels with reflective type outer layer. I live in SE NC and a window A/C is not a lotta help on a summer afternoon in my shed. Would those foam panels provide any help or would they be a total waste of money? Thanks

[@DoItYourselfDad]

The foam panels do work pretty well, I use them on my garage door. He just wanna make sure you don’t have any air gaps between the panels and the studs.

[@johnmiddleton726]

The foam panels I was looking at were a lot thinner than the ones on the doors. These may only have been 3/16” thick-if that

[@idanny76]

Why not drain the condensate line to the washing machine drain? I see a dryer there and I am assuming the washer is not that far from it.

[@DoItYourselfDad]

These units don’t pump, they’re gravity feed

[@ananbrian4079]

I need a suggestion, since Pandemic I had to move into my garage which has no windows, I live in NJ currently we had some really hot days making very difficult to sleep, I currently have a Hisense Portable AC using the bathroom vent but the garage is about 1,000 square foot that ac can’t cool the entire garage, so I think my other option is buying another portable ac and venting through the dryer vent but I don’t know how since I still need the dryer another option was to cut a opening in the garage door to add a vent and vent the ac that way but I am afraid of doing that because if I damage the garage door that can be costly, any tips I am desperate for any suggestions is a huge space and the fans are not enough.

[@DoItYourselfDad]

Is the garage already insulated?

[@ananbrian4079]

@@DoItYourselfDad thank you so much for responding yes I had it insulted is a above ground garage with part basement

[@ananbrian4079]

I think how the heat is getting in is through the garage door that’s not insulated and opening around the garage door

[@rupe53]

@@ananbrian4079 ... In NJ you are similar weather to me (an hour away from NYC) so part of your problem is a portable unit is nowhere near enough capacity. Compounding that is if the garage is more than 20 years old the insulation won't be up to home standards. With 1000 sq ft and a typical garage door you are looking at 18,000 BTUs or better just to keep the room cool. The only way to go is a window / wall unit or a mini-split. The mini-split will be more money up front but cheaper to run and VERY quiet in comparison to anything else.

[@fcaughli]

I don't know what the difference amount is with single vs dual hose unit. But I would like to somehow take an indoor unit, put it outside (makes it a dual hose) then run the cool air inside through a hose to the inside area. (no I don't want to do a mini split). I am looking into how to do this somewhat efficiently. May end up with losing enough efficiency with the ducting that the single hose inside may work the same though.

[@briannova627]

Our garage is getting too hot during these over 90 degree days .. the upright freezer in the garage gets too hot and now the freezer can not cool. I make sure the back the freezer has adequate spacing to ensure air circulation. I’ll keep a fan running in the garage aimed at the freezer so it does not shut down. Also I may raise up the freezer using some boards/or blocks so heat can dissipate from underneath the freezer. How about having an exhaust fan installed in the garage ceiling so the hot air can dissipate out the garage? I frequently travel away from my home and don’t want the freezer to experience any more problems.

[@WarrChan]

Can it share a vent with the dryer?

[@DoItYourselfDad]

If both are hooked up correctly with check valves, yes.

[@craigwilliams1060]

If you are in East Texas water evaporative cooler/swamp coolers do not work that well. East Texas in 100% humidity in the summer. I know I live in East Texas and have used evaporative cooler/swamp coolers. West Texas they work well.

[@mikeslater6246]

By definition evaporative coolers will not work at all in 100% humidity. You must have extremely low humidity for them to work. The absorption of the water by the hot dry source air cools the air but brings the humidity up. But they are usually designed for areas where the humidity is so low that the resulting humidity of adding water to the hot air usually ends up around 50% in a properly designed unit. It is totally dependent on extremely low source air humidity to begin with.

[@Lonerider1122]

If you don't have a vent, do you have a side access door you can crack open? You can also install wall vents as well.

I hate those types of units. You basically end up putting so much heat back in via that hot vent hose. Better to put in a mini split or cut in a window unit into your wall. But I live in a humid climate that isn't as easily cooled off as desert climates.

If you have a dryer in the garage but no other outlet for the air. Can't you run the AC exhaust into the dryer exhaust? Or through the dryer somehow? I'd like to see an adapter for that

You can, you would want to use a one-way flapper in both lines so the ac doesn’t push its exhaust back up into the dryer and visa-versa
