Off Grid Tiny House Air Conditioner to Package Unit Conversion

[@rebar-king]

Nice project. Thanks for posting. Note that the crimpers have two indications. Rear one for insulated connectors and the one forward for Non insulated. Use the rear INS for connectors that are insulated like the ones used here. The forward “notch” is for bare connectors.

[@johnlshilling1446]

Very well done and explained very well, even for beginners. I only have one objection... decades ago, electrical tape was disallowed for capping and splicing wires, according to National Electric Code. I know that it worked for apprx 100 years before it was banned, but enough electrical fires were caused due to poor taping, that the Code was changed. Wire Nuts and splices should be used wherever possible. Especially when dealing with voltage above 24v. 😁 It's just safer, especially for beginners.

[@WJCTechyman]

I agree. I would just cap the ends with small Marrettes (I'm Canadian and a Scottish-born Canadian named William Marr invented the wire nut while working for Ontario Hydro so that's what we call them) and then, if necessary, taping them.

[@robr471]

Great idea, I did a version of this almost 20yrs ago, because I had a basement apartment and the windows were too small to accommodate a window air conditioner. It essentially sat outside my window under a small clear awning with the duct pushing air into the room. The power cable was on a surge protector and the controls were set to "high". I'd just flip the switch to the surge protector to turn it on when I wanted things cool. Very primitive, but it made a difference, especially when alternatives were not really an option for me. Now portable ac units are more affordable and available.

[@rummy98]

Window units take inside air, cool it and blow it back into the room. A closed system. The condenser is located outside and water removed from the air is also dumped outside. Portable units don't work as well because they exhaust indoor air to the outside. If you remove air from a room, you must replace it with new outside air (negative pressure that pulls in outside air in any crack it can find), reducing the efficiency by a lot and also bringing in additional humidity. Since the condenser is on the inside, the heat and water produced are also on the inside.

This may be the best way to explain how an air conditioner works. Or at least to get an understanding of the basic components of an AC. I was looking at doing something similar, but just sorta backwards. Putting the unit inside my garage and ducting the intake and exhaust outside.

[@acrepairnearme]

To determine the speed on the AC blower motor you can measure Resistance btw neutral and each wire. The lowest resistance mean higher speed. Higher resistance mean lower speed. Etc.

[@brianluck84]

He also could have used that same multimeter to just see what wire had voltage based off speed setting.

[@WJCTechyman]

@@brianluck84 Or an even safer method of testing, using the continuity setting on the multimeter while turning the knob and listening for a buzz. You don't have to plug it in at all. The continuity setting on my multimeter looks like a sideways Wifi symbol.

[@goiterlanternbase]

18:58 When you don't want to glue two parts together, but still have a seal, apply tape on one side. It also works with caulking. After the sealant is cured, the tape even can be removed, if more pressure can be applied to the seam, like with tightening a screw or such measure. Which type of tape you ask. It depends on the job. Some tapes stick a little more to the sealant, others are thin as a hair. Painters tape, is the easiest to remove. Sometimes cling film is enough🤗

[@dallynsr]

Very respectable video and well explained. Being this is 2021 headed to 2022 fast, mini houses need 20seer heat pumps for excellent and aesthetic cooling/heat. I install 3/4 ton(9000btu) units for not very much and there’s no need for the re-engineering and sharp sheet metal work and bloody knuckles for minimal gains.

[@ericcoombs]

So cool that people can learn this type of thing on KZbin! 👍

[@shplayshiggty7537]

I dig it however 2 things I noticed. #1 an insulated boot will be better just for the fact of condensation. It'll probably help reduce the amount of heat dissapation, this is why the foam is inside the unit in the first place. This leads into #2 the foam will make a difference as well, some foams such as great stuff will hold up for awhile but it will definitely degrade quick. Find some closed cell expandable foam, that will insure it lasts as long as the unit as it holds up to water erosion. Otherwise a great idea for a hunting shack or a tiny home.

[@arihirschman6884]

Nice project. Thanks. One bit of "Free" advice - I used to manage 16 apartments that had lots of window units. The cheap 5000 BTU units never seemed to last, so I moved up to better quality 6000 (Much more selection at the 6000 range) units. $50 bucks got me at least 2 or 3 times the lifespan.

[@TinyGiantLifeStyle]

That's good to know. For a few bucks its a throw away for sure. I would never pay the summer time price for them

[@WJCTechyman]

Or, you ask the property owner to invest in PTHP units like those seen in hotels. Yes, it requires a 240 V circuit to the area you install and yes, it requires modifying each apartment with a hole in the wall in which a steel sleeve is installed but the PTHP is at least built to last as long as a whole house (central) air conditioner and if there are problems, you simply pull the face plate and swap out the unit for another one especially if it's just plugged into a 20 A 240V outlet.

[@totallyunmemorable]

Exactly the problem I've been looking to solve. Tiny space, too loud, too cold AC. They used to make air conditioners that were much smaller, apparently they no longer do. I sense a springtime project in my future.

[@TinyGiantLifeStyle]

Exactly

[@DavidDJenkins]

When doing this. Does the return need to be connected to the inside of the room you are cooling? Or can it just pull in air from where it's sitting?

[@totallyunmemorable]

@@DavidDJenkins The way air conditioners work is the bottom part with all the aluminum fins is where the hot room air enters, and then the cold air is blown out the top vents. So you wouldn't have much luck drawing air from outside your room. It'd probably work, just not very well.

[@WJCTechyman]

My 5000 BTU unit is probably about 20 inches wide (50 cm), maybe a bit over a foot tall (over 30.4 cm) and maybe deeper than its width and weighs maybe 20 to 40 pounds (mass of 10-20 kg). It's pretty small especially compared to my portable AC.

[@annespacedroid]

Put a sonoff relay set in there and be done with it. Controlled remotely, no wires running into the house. Because of the resistance (airflow) through the tube, I'd check the heat of the fan motor after it has been running for a couple of hours.

Interesting setup. I would have made the intake a bit different where crafting the front panel would be a custom sheet steel design (same kind of galvanized sheet steel used in HVAC) to fit over the entirety of the evaporator coil and then using a duct boot like you have there to transition to the return. Using tools like pop rivets and metal snips makes the work look more professional and the supply vent maybe insulated with exterior barrier-style foam sheeting and securing into place and reducing leaks with the handyman's secret weapon: foil duct tape.

[@TheSkinnzer]

Use wire nuts when making a stop termination. Or better insulation then electrical tape. It might bet rated for 600 Amps, but can it stand the outdoor condition of the rugged outdoors?

That being said, one may have to determine their best solution and electric baseboard or forced air heat may be something that can be used in the event that the heat pump can't.

Awesome! I'd use a bit of silicone caulk around all the electrical stuff, just as a precaution. Is also great to finish off seals wear the foam might flake off.

[@barnowl6807]

Interesting conversion. I might try this for an old window unit in my garage. Note however that the EER for most window units will be MUCH lower than for a newer "package unit." Most newer window units are 10 to maybe 14. The mini split or "package unit" can be as high as 30. The window unit condenser coils are just too limited in area for efficiency. Be careful, newer units use refrigerants that require pressures approaching 400 psi. The Chinese, in many cases haven't learned to solder or braze the piping to handle this or the vibration involved. I have 2 units less than 4 years old that lost refrigerant from leaking connections.

[@rebus570]

I been brasing mine up & instead of 410a I use 134 from auto parts it works great. Look up the specs on the model #on compressor mines rated for 410 & 134, same oil, cap tube kinda small for 134 but it works great no change. That is the thinnest tubing I have ever seen got to be very careful with the heat. You can only fix them a couple of times before they get lots of pin holes. It seems to only be the evap coil that dies my condenser coils have never leaked.

[@barnowl6807]

@@rebus570 What??? The working pressure of 410a is over 400psi. That of 134 something around 250psi. It will probably work somewhat but you must be filling the condenser with liquid and the low side pressure must be approaching a vacuum because the liquid can't get through the cap tube fast enough. You are probably paying about twice as much to run and the comp may overheat from lack of cold gas on the input. Are you sure that's a good idea?

[@danburch9989]

Theoretically, you could make this work like a heat pump without opening the case. In AC mode, the cold air comes out the front evaporator into the room and warm air goes out the condenser to the outdoors. If you design a duct system where you can blow the warm air from the back condenser into the room and blow the cold air from the evaporator outdoors. The indoor thermostat can control a damper door to route the air properly (much like modern day cars).

I'll be doing this on my workshop this fall once I find a cheap used window unit on Facebook market or Craigslist. However I think it would be far easier just to set the unit to high fan and max cool and then use a Rainbird temp controller. It completely eliminates all the rewiring and purchase of a relay and separate thermostat (well the rainbird is a thermostat but you don't have to wire it up yourself) so all you have left to is build the connection for the ducts to the unit, then connect them up through a window. It might be a bit more expensive than the relay but its far more plug and play, and that convenience extends to when the actual AC unit gives up the ghost all I would have to do is buy a new one plug it in and modify it to connect to the ducts, no rewiring needed.

Um... not a big fan (ugh - pun alert!) of those foam mountains in the boot and near the fan. Here's why: they will lead to air turbulences, otherwise known as low-frequency noise (LFN) and that's something HVAC manufacturers learned to dread since the 70s. LFN will usually amplify in the ductwork and can't be filtered out through mufflers etc. LFN is long known as a factor that's subconsciously raising your stress level and also negatively impacts sleep quality. If you are building your own A/C, use the opportunity to also make it as silent as possible - across the whole audio spectrum...

Back pressure on a fan causes less airflow, and thus less power. This isn't intuitive, but physics doesn't lie. Source: am air conditioning design engineer. So, no, restricting airflow won't burn out the fan. It could, however, cause the coil to freeze up if the restiction is too severe.

Maybe a cheap little 6-in inline booster fan on that flex would be the ticket

[@ckm-mkc]

You would do this to move the noise out of the house, it's a cool, cheap hack to get that without buying a mini-split for $1000 (which still has a fan inside). Probably way less static pressure than the original which was forcing the air to do a 90 degree turn right after the fan. And if you use a 6" duct, it will have more surface area than the original outlets...

[@Ares-jx4ep]

yes, that incredible factory warranty on cheap window A/C units is worth far more than cutting a hole in the house for said unit......smh. What if the "building" you want to cool "isn't". Lets see... cut a hole in a tent for a window A/C... yeah that'll work well. What if you want to cool a stone/brick/concrete structure? What if you don't own the building? "Hey Landlord, I'm sure you don't care that I just cut a hole in this wall I don't own."

[@TinyGiantLifeStyle]

NOISE, large hole that will not be the same on next years model. Also, its a $97 throw away Walmart unit. Couldn't care less about the worthless warranty.

[@hellhound1389]

A few years ago I put AC in my workshop/ shed. It looked easier to do what I did and just cut a hole in the wall and frame it in

[@flanny701]

the whole point of this is for if you dont want to deal with the noise of the compressor and fan of the ac if you dont mind it then this is all redundant just throw it in a hole in the wall like you did or a window

[@slacky4358]

I am an HVAC guy and I did the same thing to my RV lmfao except I had to put a delay switch on the compressor because it was tripping breakers

[@TinyGiantLifeStyle]

The thermostat I used has a short cycle delay time that can be programmed. Good point though.

[@KentuckyFriedFixes]

Have you ever wondered why your neighbors might pray for your ruination?

[@TimFuller]

Cool. You got me thinking the entire rip it apart to bypass internal thermostat and select fan speed is redundant if you just set it on high and leave the existing thermostat maxed. You could still build an external relay-thermostat unit but you'd never have to mess with the guts inside that unit which would put some people off. #hobomessiah

[@twoeightythreez]

He sets it up this way so you can use a standard house thermostat to set and forget the temperature.it’s basically central air for a tiny house.

[@ownjam]

This is a great idea but you can find a 110-unit like this that also has a heater on it it's about $350 on eBay

[@goiterlanternbase]

The first thing that has to go in such a unit, is the fan😉

[@sjr7822]

The host is very good at explaining and instructing, but, Clearly, my brain isn't wired to understand this, I was with him for 7 minutes before my eyes started twilling. Anything with math, I have never 'connected' but, I'm still curious and envious of those with the talent to Get-r-Done

[@mortneff4674]

I like the idea and concept but wouldn't it be better to hook or use a ceiling fan & Light remote control to it! there for by passing the need for the 24V box!

[@Chad_White]

This is great..would be great for a camper.

[@jerryrigsit5400]

Maybe for a 10,000btu unit. Not smaller. Might be usable for a skoolie or a revamped camper

[@chrischappell7117]

Nice informative video. I don't know if I missed it but what is the advantage of doing this vs. just installing it in a window or making a hole in the house and installing it there? Just trying to understand why doing this VS. just installing the window unit. Thank you.

[@kellypophamjr5777]

Noise

[@ionstorm66]

To add to this, the compressor makes most of the vibration and noise. Moving it further away, especially with flexible ducting, will make it much more quiet. Also packaging. You make want to move air around a space, a ductless unit is very poor at circulating air in a room, it just sucks the air right back in.

[@TinyGiantLifeStyle]

low noise and a small hole through the building.

[@marctorr5551]

Been looking for something like this, thank you!

[@TinyGiantLifeStyle]

Glad I could help!

[@wyldanimal2]

at 5:33 notice that one is Non, and the other is Ins. you use the Non for Bare metal non insulated crimp ons, and the Ins for Plastic Insulated crimp ons. you Used the Wrong one.

[@Lierofox]

Came to mention the same thing. The Non-insulated opening tends to shear through the insulation when it crimps, exposing the metal on the connector and partially negating the purpose of the insulation.

[@thereynolds2725]

Yes, but the non-insulated is a better mechanical connection. As this is all enclosed inside a housing, it really isn't an issue.

[@davehoward3645]

Nice video! You seem to be very knowledgeable on the subject. I have a question if you would be so kind. I was inspecting my outdoor unit and didn’t pull the power, as I took of the cover it contacted one of the contractor wires? It now doesn’t work. It seems the contactor still works but it doesn’t turn on although I can hear a slight hum. What do you think I need to replace?

[@ken48229]

A couple different things 1. check or replace the fuses in the disconnect. 2. The power going to the disconnect comes either straight from your meter or from your electrical panel in the basement check those breakers.

[@TinyGiantLifeStyle]

Great job on a very useful idea!! Thanks

[@TinyGiantLifeStyle]

Glad it was helpful!

[@boysrback5690]

Old bread knife is your friend for foam.

[@Adam-uo2mc]

Please do not just cut off the unused ends and wrap them in tape, this is extremely dangerous electrical tape is not meant to be used as a insulator on it's own. Instead crimp on a dead end or a coupler or use a wire nut then tape them up to keep them out of he way.

[@peterrogers1616]

Ok lame

[@Adam-uo2mc]

@@peterrogers1616 If you want to die in a fire this is one way to do it. A poor connection under the tape will cause excess heat that regular tape can not handle so it will just melt, There is more expensive tape that can handle high heat but it's cheaper to use wire nuts. If you personally want to risk it that's up to you. I'm just giving people some important safety advice.

[@thefirstmissinglink]

Was cringing when I saw him wrapping up the ends with tape. Shrink tube came to mind for the cut ends.

[@TinyGiantLifeStyle]

That is NOT what was done here. Look closer.

[@thereynolds2725]

There are no connections insulated with tape.

[@1987FX16]

Nice, almost a 50% savings doing this. Your could have 2 5000BTU ac units for the price of one off the shelf unit.

[@almeal406]

do you run the air supply and return lines to the same room?

[@barrybretz6073]

Two relays of the same kind would allow you to leave the fan on independent of the compressor

[@chadelmore69]

We talking about a/c and a/c accessories?

[@bobbyruchalski2368]

Curious if this unit is still working/cooling properly right now? I had a situation where I had to do this same thing years ago, so this video can be helpful to people. Mine worked for a summer than gave out/broke. Don't know why it broke quick, ductwork seemed large enough.

[@TinyGiantLifeStyle]

Yes it working today

[@p1epoppa]

The American Way 😎💪🏽

[@whydontyouaskme]

I thought you were going to split it apart and leave the outside parts outside and the interior parts inside.

[@goiterlanternbase]

18:23 It's not like a glue, it is a glue🤣 That's why i said earlier, the screws are not necessary. This will never come apart until the metal is rusted away.

[@BillSias-op7xw]

Why not just extend the wiring from the original controls and mount the thermostat and fan controls on a switch plate further away, duct as you have shown?

[@BigDmike24]

Set unit settings on high.Use an inkbird control the temp. No wire hacking required.

[@funnycatvideos5490]

i thought the exact same lol.

The $549 package unit provides heat as well though, no?

Sure

[@dopeymark]

Smart stuff. Good stuff.

[@jlowell55]

So if your getting the cold air from the top of the unit, what was the purpose of putting the extra piece on the front? After watching 5 times, I still do not understand that.

[@TinyGiantLifeStyle]

Return of indoor air. Otherwise you waste energy sucking in hot outside air

[@redneckgaming97]

How well did it work when u hooked it up IV been trying to something like this for my camper I'm thinking about trying it the way u did it cuz I want to hook it in to the heat ducts in my camper since I removed the furnace

[@TinyGiantLifeStyle]

It works well to this day. Just get the duct size correct and use vinyl duct for sun exposure

I was noticing, a lot of comments on here, include shity, for shitty, realy for really, no capitalization for sentence beginning words, no punctuation. I guess commenting on how the job is done improperly, while improperly writing such, is to be expected in the tidepod generation.
