Building My Own Home Office 12

This video shows the installation of a Mr. Cool 12K mini split heat pump system in an office. The installers discuss positioning the indoor and outdoor units, drilling holes for refrigerant lines, and mounting the units. Some challenges arise like difficult access for connections and extra lineset coils. After lunch, they address these issues and continue the installation by connecting wires and refrigerant lines between the units. Safety checks and insulation of lines is also done. The last steps involve installing a control unit and finishing the vanity. The installers explain they are new to mini splits but worked through difficulties. In the end, the system provides cooling and heating and the installers are pleased with the finished office space.

The bolt, the lines, and of course the dog got 10lbs of ham. It’s nice to see that you’re one of us. Most videos just show perfection.

[@IronSikh44]

I was thinking the same thing. I still end up drilling 8 holes when only 4 were needed. And my dog ate a bowl of brownie batter the other night. Lol. This video proved Eric is not perfect. Probably why we love watching their content.

[@jwk4567]

I think they regularly show us that they are human! Owning up to any mistakes, talking about learning new things, and having to re-do things here and there. But this one? Especially so. I thought, much like you I bet, "oh, that's how this project would have gone for me!" Expect I would have had to take my dog to the vet I'm sure! lol :)

[@sdhlaw1]

I agree. It's good to see that sometimes the professionals have the types of issues that DIY-ers like me seem to have to deal with multiple times on every single project. I love videos that are truly real.

[@stacyseguine8904]

The reason you lay the lines flat is to avoid oil traps. Also, I put the lines thru the wall in the left side. That way you can take down the unit later for serviceability. All in all not a bad install. FYI, that’s a one day job for 1 guy.

[@sqearly]

Sometimes teaching is showing someone how not to do something or what to avoid. It was all very informative.

[@locke3141]

Is that why people always say I’m such a good teacher!?

[@jamespppyacek342]

Agreed.

[@wrusty3767]

Pro tip: if you want to find out where your hole will emerge on the outside wall, use a long 1/8"drill for a pilot hole from the inside. If it doesn't come out in the correct location, you can drill again and easily patch the small holes each side. Then just follow the small pilot hole with the larger hole drill.

[@jessethecarpenter]

I love the progress Jay has made. I’ve been watching for years, and seeing him really turn into a good carpenter gives me hope as a later in life starting carpenter that I can do it as well! 😊

[@Cooper1]

A real HVAC guy would just notch that stair stinger to get access to the lines. 🙂 Love the bonus video.

[@AmandaComeauCreates]

Stair stringers are governed by structural building code. If HVAC guys are modifying them they are compromising structure.

Pretty easy solution would have been to attach the fittings above the stairs and then just pull them down…

[@creylacoste4981]

That wouldn’t have worked if you knew how stiff and delicate they lines is

[@someyoungguy6990]

Erik that style of split system are the standard unit in Australia. Quick tips. Always run the unit on fan after you have had it on cool as it helps dry it out and prevent condensation building up when turned off. Keep your filters clean as it helps with air flow. Every two years get the inside unit professionally cleaned or buy a Amazon cleaning kit and do it yourself to remove all the fine dust that will build up no matter how clean you room is.

[@marymigliore3396]

It looks so nice ! Can't wait til it"'s done !! I LOVE YOU ALL @ P.B.B. !!! 🥰🥰🥰🥰🥰

[@estebanespinoza5022]

This has to be the best Mr Cool install I’ve ever seen, many other creators don’t show the full process, they condense all the installation process into a 30 second ad (not that it’s wrong) but they don’t show you any of the actual struggles! Great job guys!!!

[@laurenbaptiste1200]

Just found your channel. I have been binge watching since. I love the camaraderie you all hv. Very entertaining. POV. Non builders watch tooo.

[@Dalewolf777]

My son and I installed a Mr. Cool in my garage in Florida. It was a very easy install and the unit is incredibly quiet. You can hardly tell when it’s running. I was impressed with how quickly it cooled the space and it usually took only five minutes or so to get the garage to temp. It made working in the garage during the summers a real pleasure.

[@markmix2491]

While helping my dad as a kid he would say "hand me the knuckle skinner". I knew he wanted the crescent wrench.

[@2flewover1]

Not angry,..hangry. Fun to watch as always. A basin wrench would've been perfect for the line behind the stringer.

[@LesterSuggs]

Put a *Mr.Cool* in my garage 2 years ago. one of my best decisions, ever. *PLEASE NOTE* when you place the remote in the wall caddy, the caddy has a tendency to remove the battery cover. I put the remote in the caddy upside-down. My coils are vertical, and it works fine.

[@Cpt.Croissant]

Love how relatable this video feels. Trying to tighten something in a tight spot with channelocks hurts my souls

[@bigvegass]

Keep that unit clean internally. Like the squirrel cage fan. Takes very little imbalance to get it vibrating. Other than that, enjoy silent cooling and heat.

[@N.A.J.]

This is not disclosed by any installers or users. In reality these need deep cleaning annually. To the point of fan removal and cleaning. Blow out the drain line sludge build up, and wash out the coil. If you live in an area where mud dobbers make nest, they will make nest in the drain line. Cover the end of that drain line with screen wire.

[@rasmusheise1]

@18:18: Thank you for using mm's - and making us non-us feel included 😀

[@ThePlockets]

Not to make you feel less included, but in the US "millimeter" is often used as a kind of generic slang for very small measurements, since inches are the smallest commonly used measurement (and they aren't that small). ;)

Hello kelly from canada here. In automotive we would run into the same occurance trying to tighten a fastener obstructed by vehicle design. The solution was to use a "crowfoot" socket with extension than connected to a ratchet handle. They make them in a regular open ended design and compression line design. And of coarse I never miss an episode. Thanks a bunch. Say hi to Jamie for me!!

Top tip to those that don’t know, always run you AC drain line to an actual drain. Nothing attracts termites like a constant drip of water going to ground during hot summers.

Oh no a 'Hangry Eric'. Maybe you should have started eating the ham earlier as dogs aren't to be eating ham. I initially thought you placed that Split System in a great place but then seeing the struggle with that coil 😬 you did a great job.

The top of those wedge anchors are designed for you to pound them in. By putting on a nut, you are basically pounding on the threads which is worse.

I am so happy! Finally get to see one of the Perkins boys lose their cool. I'm physically disabled and visually impaired (or as I call it not a full working model) and I try not to lose my cool doing some of these projects for my honey but I regularly do. Nice to see a pro full working model losing his cool. 😅😂

[@denes44]

You could definitely install these after everything is finished, that's true, but if you install the line-set during construction you can achieve better results. I know you are not really care about air-sealing, but now you got a big hole on your ZIP panels behind the siding that is not protected. During construction you could have put the line-set inside the wall, so it goes into the wall at the top, and comes out on the outside behind the outdoor unit, which looks better. You can also make sure, that it does not comes out between two siding boards, or even install a block for it like you would for outlets, lamps, etc. Or even better, use an Airex Titan Outlet.

[@locke3141]

You’ll be amazed how well the dry mode alone works on those Mr cool units. We had one in an old house and almost never used ac, just dry and it was perfect.

[@heatherclayton-callaghan4270]

All our homes in Queensland Australia use these Reverse Cycle Minin split A/C units. They work brilliantly in our sub tropical humid heat and warm well for the few days it gets cool on winter. To be honest ive never used one for the heat but I'm in a new rental this winter so may have to. Rarely hits 0°C here tho. It's 5th June now and 5-6°C is for low , days still high 21-26°C.

[@BigJohnson1566]

Call your HVAC guy and have him cut the line set and recharge the system. Would look much nicer

[@stevenhartley1350]

Personally I would have run it out of the opposite wall as it would have left a cleaner look and would left less issues for the connectors between the piping. Also the condensation produced can be considered corrosive to concrete (or so has been mentioned on several other posts I’ve watched on here).

[@glenlongstreet7]

I got my MrCool back in 2019. The installation instructions were for the wrong machine, the mounting template was for the wrong machine, the tape to wrap the feed lines wasn't sticky. I had a friend with a vacuum device help me because this was not a DIY Mini split. But amazingly, it worked until last fall when the "Step Motor" began to 'cry'. This is the motor inside the Head that drives the squirrel cage fan. It took a while to find a replacement step motor. The replacement cost less than fifty bucks. I watched a video on how to replace that step motor. There are hidden screws that are inaccessible. But not too much blood was spilled getting the old motor out and the new motor in, but the new motor doesn't cry. If you are wondering what the crying sounds like, it is not crying.

[@glenlongstreet7]

In the middle, at the bottom, you will see a small square cap. There is a hidden screw underneath it. You need to know this if you ever need to take the cowling off. The blades of the inside fan are blue, but within a year they will be black. Just wait till you try to wash the blades!

[@cleansebob1]

I would have mounted the inside unit closer to the 3 exterior windows (where Eric wants a TV). The reason is that the windows are where most of the heat gain / loss occurs, so you want the conditioned air blowing into that space. Otherwise, it will be cold in the winter, hot in the summer. Would have also made the lineset installation much easier. Just my 2 cents...

[@worldblast9039]

The wedge anchors are designed to be hit on the tapered part on the top. If you hit the nut as you found out you will damage the treads.

[@idontthinkso666]

His anchors didn't have tires, so the treads were okay.

[@dbrank28]

I lol’d at “And we are going to drill this slab…..on hammer mode” then Jason checks to see if it’s in hammer mode

[@Dani_Escalada]

Wedge anchors bolts are supposed to be pounded on the bolt itself, what seemed to happened in your case it's that pounding the nut it budges with the bolt and make it spin together. If you can still remove the nut do it, try to clean the threads or use a new nut that might make it

[@focus19551]

Jay is the pro! He installed one at his place… listen to him

[@jeffreybogart9832]

Oh my god the concrete anchors! 1. Have the nuts slightly low when hammering in - if you're pounding on the nut, you are jamming it into the threads and messing it up. That's why you can't get it back off and you end up spinning the anchor when you try to tighten it. 2. Tighten the anchor and make sure it's seated BEFORE you install whatever the anchor is for- ESPECIALLY if there's a cushion.

[@mitchellchambers4852]

Yeah, work and little talk. Thanks.

[@_JamesBrown]

Wow, this was way easier than the Mitsubishi Trane units I put in my remodel. You didn't have to evac the lines of air or add any additional R410a. Pro tip: if you didn't want that excess coil from the line, you could but a cheap flaring kit from the auto store and shorten the lines up.....however, your lines were already charged, so nevermind.

[@stevew9563]

How does the charged lines work? Do you pierce a cap when tightening??

Next time turn the drill in reverse when you need to start it because the pilot isn't long enough. It won't bite as hard and you can score the surface.

Intermittent fasting gets easier and becomes easily a way of life but the trick is to not eat sugar, carbs or processed foods.

Erik... I hope that you will do a followup video or a couple, one for summer, and one for winter on how well the Mr. Cool 12K mini split heat pump system works in you office space. I have a covered back patio that I would like to inclose and turn it into either a sunroom or a indoor exercise room. The interior walls would measure roughly 15 x 18 feet or 270 sq/ft which equates out to 5,400 needed BTU's. Since the roof over the porch is pitched I think the 12,000 BTU unit would cool/heat the area I want to close in.

[@RicardoJunqueira]

Why not using that wall from the closet close to the bathroom door? The condenser would be close to the other ones tucked in that corner behind everything.

[@scotts4125]

I'm 8 minutes in and wanted to add why that tape doesn't have adhesive on it. They (whomever they are) have figured out that some A/C line insulation can actually degrade the copper. Some of it is caused by the adhesive. Some is from the sun. Most of the mini splits come with that non adhesive tape now. The other really odd thing is they have found corrosion down or upstream from where the insulation is. In other words it wasn't right there but somehow it migrated but still caused by the insulation. I have a Mr.Cool in one of my garages and it's been amazing.
