I've been looking into the mini-split systems and had a local HVAC business come out and quote me a new system. He discouraged mini-splits because he said they were much more expensive than a traditional heat pump which he quoted me $10,000.00 for a 1150 square foot home. Thats two HVAC folks that gave me crazy priced systems that I can buy online for half that. Not going to pay two guys $5 grand for one days work. I'll go DIY like you.

[@MichaelOstrowski-zw7uf]

Just a friendly suggestion. If you are in an area that has freezing outdoor temperatures, and you use this for heating, you will want to put the outdoor unit on a stand. What will happen is the outdoor unit will go into defrost to melt the frost (ice) that accumulates on the outdoor coil. This is done automatically. As the frost melts a build-up of water will turn to ice during freezing temps. When this happens, eventually the ice builds up in the outdoor unit and the coil gets damaged from the constant freezing and thawing. Having the outdoor unit up high will allow the water to drain far enough away from the coil before the water freezes.

[@richardrussell1025]

Installed a Klimaire minisplit in my garage. Going good for 2 years now. It was cheaper too than other brands. I wanted to cut my lines to size so I bought a vacuum pump, gauges, and line tools off Amazon. First time ever installing one. Just watched videos and took it a step at a time. Note you can for about $300 bucks and a test, get licensed yourself to buy refrigerant.

[@gordonshute8816]

The filters on a mini split are notorious for getting clogged pretty fast in a wood shop. No matter how good your dust collection system is, you should probably clean/ replace your filter monthly depending on the amount of time you spend making sawdust. If there is a way to figure out a prefilter, that would be best but that's hard with a mini split. Great video. Doing it yourself is pretty awesome and definitely does give me a great feeling.

[@Fixthisbuildthat]

in my experience with the old one, the filters were never the issue. they are really filters in name only, lol. it was the build up on the blower spindle fan that was horrible and I never even knew it

[@lennyross2813]

There are a couple of youtube videos out there addressing this issue. One channel that comes to mind is A Glimpse Inside.

[@RaffBuilding]

I installed a Fujitsu 2 zone some months ago. The unit is pre-charged with all the coolant you need, but I had to borrow a vacuum pump and gauge set to vacuum the lines before releasing the coolant. I planned to cut the line sets and flare the ends, but got nervous and simply located everything to work with 25' and 35' line sets. In that case, I could have gone the Mr. Cool route.

[@backwardsmachining7526]

[@justplanebob105]

I really liked this one. My garage/shop needs a mini-split in the worst way. The uninsulated garage door gets full afternoon sun. Summer's are murder. I'm just nervous about getting on a ladder at my age. The condenser would sit in direct sun on the south side of the house. Is that an issue?

I installed a Mr cool unit about a year ago. I did have a filler valve that leaked from a factory defect. Local hvac repairman fixed leak and refilled refrigerant. Mr cool offered to ship out the new part. But I had the repairman just replace the little valve.

[@BiggMo]

Please do a video of restoring a wall that was mural painted. I primed and painted, but the edges and brush marks are telegraphing through. Is my only option to retexture (orange peal) the wall?

[@mikedodsonlabview]

My question is about dust. I have a wood shop and despite my efforts things get dusty when I’m working. Are you compensating for the dust in the air with additional filtering or just relying on the internal filter. I’ve seen other DIYers who build additional filtering. It’s one of the reasons I’ve hesitated installing a mini-split.

[@sparkythebuilder]

Just an FYI: You are not allowed to use regular Romex in an outside location. Any conduit outside is considered a wet location, even inside the conduit due to condensation.

[@stradric]

Your DIY origin story hits home. Predatory contracting is rampant, makes it more difficult for everyone, and makes the world a worse place. We need more honesty in business and the world.

[@Chris-ec9lc]

get a loaner vacuum pump and gauges from the autoparts store. You will probably need a 1/4 to 5/16 adapter to hook up to the access port. Please pull a vacuum and check for drop, you are leaving air in the system.

[@vincentnucaso6776]

@Fixthisbuildthat - If you have a partially finished garage and you want buy the appropriate sized Mr Cool unit, how do you calculate the sq footage with an open ceiling to the A-frame roof?

[@Fixthisbuildthat]

great question and honestly I don't know. But I'd imagine in the winter is where you'll have the issue. Summer time the upper area shouldn't matter as cool air is heavier. And potentially adding a fan above the rafters could push that warm air down in the winter

Thanks Brad. How's the new home doing?

[@kamo7434]

The problem with these DIY systems is long term serviceability. Not one contractor out of dozens in my local area will service or repair DIY hvac systems. Arguably you could just install another one considering the price point, but it's something to consider nonetheless.

[@williamellis8993]

This is why I had mine installed by a local HVAC contractor. No regrets.

[@kamo7434]

@@williamellis8993 Yep, me too. Not to mention the Daikin I had installed has a twelve year warranty. I spend enough time out of town and away from home that I didn't want to leave my wife with a headache incase anything goes wrong with the HVAC system at the house. Now we can be rest assured that help is a phone call away if anything breaks down.

[@Fixthisbuildthat]

Definitely something to consider. You'll likely have to find a side-jobber to do work unless you do it yourself.

[@jb510]

​@@Fixthisbuildthat hard to find a "side jobber" with the proper hvac equipment to service them. Thankfully, I'm friendly with my two local hvac companies and have hired them for other work They don't like servicing it, but they will. I've never seen an industry so hell bent on brand loyalty as HVAC. They'll all absolutely trash talk any brand they don't directly sell.

[@kamo7434]

@@Fixthisbuildthat For sure. I'm not saying don't do it. Heck, I'll probably install a DIY unit in my detached garage this year. But if that unit goes out it's simply an inconvenience not an emergency where my family is going to freeze. I only want to caution those considering going the DIY route to think about downsides and if the application is appropriate.

[@tonyi4085]

Three things: 1. Straighten out the most of the line set before inserting it into the wall (it’ll make it much easier) 2. I wish there was an option to completely replace the condensation line with PVC. The corrugated tubing will trap water and get moldy. 3. Make sure there’s a pitch away for the drain

[@Fixthisbuildthat]

great tips

[@truthreigns7]

What do you mean by "too bad it is not 2016" concerning pallet wood?

[@tylerufen]

my concern, with my luck, would be to run into a burr connecting the lines, vent all the refrigerant to the atmosphere, lose the vacuum, the thing is essentially scrap because those connectors are proprietary, and i just gotta get a new one... i see it as a gamble because of the installation, but it's still nice to know it exists because of the price point...

[@davidwatson4510]

If this type of unit is installed in a house that has central ac now, does this unit use the existing vents to each room? I think there has to be a interior blower in each room. Also, how does this unit control humidity? Is it the same as central air.

[@Fixthisbuildthat]

no, this is a ductless unit. and temp and humidity are controlled by a sensor on unit or remote

[@yeahitskimmel]

Learning to use a vacuum pump and about the compressor/evaporator/condenser seems like something anyone could do if they are already capable of all this. I really like your HVAC guy story tho

[@Fixthisbuildthat]

yes, it's not so much pulling the vacuum or reading pressures that is hard. It's actually sizing, cutting, and flaring the tubing for good, solid and clean joints that seems to be the difficult part and most common place for failure from what I read.

[@JCWren]

That's actually the one thing I don't like about Mr Cool: All the extra length in the line set. You can coil it up or whatever, but it's still there, and still ugly. I need about 8' for mine, and the minimum is 10', but at least I don't have an extra 13' of line on it. Flaring the joints and pulling the vacuum is pretty easy, IMHO.

[@zaprodk]

Remember to tighten the caps on the valves good and tight!

[@alwayzdrummin]

A great place to install one of those would be in a shed you might work in....

[@Fixthisbuildthat]

my bud Scott at Everyday Home Repairs put one in a shed run off solar powered batteries. Killer setup, though I'm not sure how long it could run full bore on solar alone.

[@alwayzdrummin]

@Fixthisbuildthat that's a neat idea. I was implying where the rest of the shed build was. I need to build one once the weather gets warmer and as I started to design it you started your series. It's been helpful and I'd like to see the end.

[@sapelesteve]

Looks like a nice unit Brad. I was wondering if the company would still honor the warrantee on a self installed unit? Also, haven't seen any videos on your house in the woods? Are you still working on that house? Just curious. Thanks! 👍👍

[@Fixthisbuildthat]

hey, Steve. They definitely honor the warranty on the DIY kit. It's specifically made for weekend warriors to install. And there will be more vids on the new property soon. Been a slow start to the year

[@mikeclark2720]

All 3 components come pre charged, not just the line set.

[@Fixthisbuildthat]

Sorry, that is not true. The lines are pre-charged, not the indoor or outdoor units. Excerpt straight from the patent #US-11747025-B2 page 36. Verbatim, no parenthesis added by me. 😀 Female quick-connect connectors are disposed at either end of the pre-charged line-set, in communication with the conduit piping, and are equpped with a variety of features specifically designed for the containment of refrigerant within the pre-charged line-set and the calculated release of the refrigerant into (and only into) the indoor and outdoor units of the HVAC system via mating male quick-connect connectors disposed on the units themselves.

What’s the best location to install a mini split in a 12x32 shed converted to tiny home? On the end of short wall or long wall?

[@Etacovda63]

short wall, typically

[@JH-zy1dj]

How could you pressure test your inside without hooking up to the heat pump and opening the valves. There is no pressure in the lines until that point.

[@jb510]

Mind blown... when I installed mine it never occurred to me I could have installed the lineset mostly inside the garage... in hindsight wish I has for one of the air handlers (3 zone system with 2 into a garage/shop and 1 into a detached shed office). FYI, smart phone control is super nice to be able to turn everything on an hour before I head to my shop. It does have a couple annoying things, like you can't schedule it to go into FP (Freeze Protection) mode which is the same as setting the heat to 45F. Lowest you can normally set in regular heat mode is 62F. And can't do things like "always turn off after 4 hours". I just schedule mind to go off at 4pm and midnight in case I ever forget. Overall, 3 years later, still super happy with the whole thing though!

[@Fixthisbuildthat]

gotta tell yeah, it was a huge extra pain doing it that way though, lol. That dang water heater really made it tough. I'm going to try and hook it up to Home Assistant and do scheduling that way if needed

[@jb510]

@@Fixthisbuildthat LMAO... of course you use HA. Anyway, installing linesets into covers is always a PITA, I sure extra PITA behind the water heater. One thing to be sure of is you have good slope to your condensate line and that wherever it exits it won't freeze and get plug. I use mine as much for heating as cooling, imagine you will too.

Probably just in cooling mode. If in heat mode you can probably set it a lot lower.

[@Fixthisbuildthat]

fair, but I would have had the electrical disconnect done professionally anyway and the pad is literal buy and drop in place. So it's really just the hole through the wall. And if you don't have brick that's a breeze

[@mphuie]

Mr Cool units are 2x the price of other DIY models. Their lineset can't be cut so you're going to coil the extra unless you're lucky on the length. All you need is $150 in tools. Check other brands to save over $1100 over the unit that was installed. Same warranty.

[@scottbeverly188]

But, do the others warranty the unit if you do the DIY? All the ones I have researched require a certified tech to do installation for the warranty and local techs will not touch them because you didn't buy their systems.

[@vonnyrotten]

great video, but out of curiosity, why are you doing this on your "old" house? aren't you in your new place?

Hmm thise prices seem wack, in my country they are like 2-4x lower. But we have a very large market for mini splits I guess :)

[@fudpukker]

Hey Brad, great install. BTW, the outdoor unit (compressor) is pre-gassed with refrigerant. The lines are usually empty. The indoor unit is filled with Nitrogen gas to keep it clean and prevent oxidization. That is the noise you heard when removing the plugs from the indoor unit.

[@busterulmer7092]

Having installed a few of these, the condensing unit (outside unit) has 99% of the refrigerant in it, the evaporator unit/ fan coil (inside unit) and line set have a holding charge. This is how you avoid pulling a vacuum on the system. Once you tighten down the connections you pierce the line set seals and it's ready to go

[@Fixthisbuildthat]

This is a common but inaccurate statement as I clarified in the video. But don't take my word for it. Here is the direct wording from Mr. Cool's patent #US-11125479-B1 😀 Apparatuses, systems, and methods for providing non-expert installation of HVAC systems are provided. The HVAC system includes an indoor unit, an outdoor unit, a first pre-charged refrigerant line-set, a second pre-charged refrigerant line-set, and a line-set coupler, each containing pre- pressurized refrigerant securely positioned therein prior to engagement between two or more of the aforementioned elements. The first pre-charged refrigerant line-set is couplable between an indoor unit refrigerant port of the indoor unit and a first coupler end of the line-set coupler. The second pre-charged refrigerant line-set is couplable between an outdoor unit refrigerant pot of the outdoor unit and a second coupler end of the line-set coupler.

[@thezfunk]

Mitsubishi mini splits are supposed to be really good quality. Very disappointing to see the whole system failed after only 6 years.

[@rick2tube]

Agree and good to know paying for Mitsubishi does not guarantee long term reliability.

[@Fixthisbuildthat]

Completely agree. I paid up to get the Mitsu when I bought it, thinking it was the best in market....apparently it wasn't. The exact failure was a leak in the evaporator coil caused by corrosion. There was no coating on the fins or tube brackets to prevent rust

[@machiavelligaming9755]

So if you needed a coolant recharge do you just replace the pipes?

the outdoor unit still has a refrigerant supply line, so you could add if you needed to

[@geminithugbaby473]

There is no refrigerant in the line set . How would one keep in the charge when connecting the lines to the evap and condenser? Impossible!.. the condenser is where it hold the charge . After u connect the lines you evacuate the lines as well as the evap once u have a good vacuum u open the valves on the condenser and they then get released within the lines as well as the evap . If u need to change out the evap or do a repair in which u need to disconnect the lines u turn on the unit on cool close the valve on the liquid line once that is done the pressure should drop on the suction line and with your gauges once the psi drops close to 1 psi you close the suction line valve and all your refrigerant is stored in the condenser

My biggest problem is trying to find a MrCool small enough and at a good price. Right now I can by a 9K for less than a grand. While a 5K is over a grand....😔 The 5K is just over what I need. But the 9K has the price. I only need something for upto a max of 250sq ft.

[@rupert310]

You should have done a video on Mr. Cool universal. That system is more compatible with peoples homes and would make great content.

[@Fixthisbuildthat]

hmmm, i'll have to look at that one. just went for a plug and play for this install

[@thezfunk]

I installed Mr. Cool for my new gas furnace and AC. It has only been a couple years but so far, so good!

[@ivandalisay7609]

That look @15:25. 😂

[@mysticshadow425]

Good luck getting one reputable hvac technician to touch your dyi installation 🤣 I certainly wouldn’t so many things wrong.

Not pre charged it is dry sealed with nitrogen

If I didn't know any better . . . . AND I DON'T. I think Brad is gonna print out a flange for that hole in the brick.

[@Fixthisbuildthat]

now I feel like a fraud for not doing that

[@that_jason_black]

@@Fixthisbuildthat Don't feel like that Dude. You are doing a lot. Looked like filming this took you out a bit but love the channel and can't wait to see more.

[@dannybradley9346]

Very good video. But, please, either you or somone else reading this, suggest a comparable made-in-USA model exists, so that a Chi-com unit does not need to be bought.

[@kamo7434]

Asks the guy likely posting from a phone or computer made in China. Why can't you just ask for a unit made in the USA? No one wants to help a xenophobe and/or racist. And FYI everything is made with globally sourced parts these days.

One item of note is that when not using a torque wrench, your tool will not say "click" for you so you must manually say it yourself

[@Fixthisbuildthat]

😂

[@user-ps2ur3bo1o]

always follow your unit installation manual guy's

[@sarinhighwind]

Id be using zip toggles if i wasnt going for studs

[@chadgreen100]

Thermal camera reference, please?

[@Fixthisbuildthat]

It's amazing. FLIR ONE EDGE PRO Thermal Camera - amzn.to/4brIsps

[@chadgreen100]

Thank you

[@user-ps2ur3bo1o]

yup you always want to buy charged up units it is very costly to hire an Hvac guy to do it for you !
