TAKE the GODDAM PICTURE OFF the WALL when you’re working there!!!
Think its expensive to call a good A-C technician, CALL A BAD ONE !!!!
Yep.
I do these videos for two audiences from my point of view
First for the guys who will be taking on these projects
Second, and likely more important, for the guys who just find this entertaining. These guys with this extra knowledge are going to be harder to cheat.
A disconnect should be installed on the electric feed and a whip from the disconnect to the outside unit with THHN wire to the unit and from your breaker panel to the disconnect. It appears you ran romex in your pipe which would not conform to code where I am.
I think you are right
I was replacing an existing install and rushed for video.
Everyone, do what's code in your area. Be safe.
Non-electrical water pipe also 😅 I've spent time in other states, the things you see that won't fly even to a diy homeowner in your area. I saw non cemented water pipes running electrical on a bank in Kentucky exterior.
@@braithmiller yes I didn’t want to torch the entire electrical of the install, but it’s all wrong. As a power lineman for more than 4 decades, I’ve come across many installs that have had me scratching my head. The ones that really baffle me are the bad installs that pass inspection.
@@edge1289 Inspection doesn't mean much when the inspector doesn't know better. Even my no permit installs have to comply for liability and so they can just pay the fines when caught instead of starting over.
@@edge1289 You mean like the one I started to trouble shoot the other day where they had the main breaker tripping the common? Another tech was there telling me the site was cold because he killed the main which was in a separate panel however while line to common was cold, line to ground was hot. You had to shut down every breaker individually or pull the meter to shut down the entire building. How that passed inspection I'll never understand.
Best!
Thank you for sharing this video, and all your videos. Sorry to be pedantic but he water flashes off rather than boils off. I've recently been looking at a safety case for a steam turbine low pressure heater if the non return valve fails. Only a certain percentage of the condensate in the heater will flash off from about 3 bar to 0.06 bar and in the process it will take some time to do so.
Just keep the lineset from being coiled verticaly, and test your flares with big blue leak check and you will probably be fine.
These are the biggest mkstakes i see mostly as an HVAC tech.
I bought a 600 Turkish Lira 9000BTU, 3.5COP mini split 17 years ago and it is still running...
The simple reason for the different fittings is 400A pressures often exceed the capacity of r22 and r34 gauge sets and equipment so to play it safe they use a larger fitting and the equipment can withstand around double the pressure. For evacuating the system it should be OK to use an adapter on an r34a gauge set however most older gauges and their hoses can burst at the operating pressures of an r400a system. The newer systems are Iso-Butane and Propane based and are the ones you may have heard about exploding in dorm rooms, etc over the past few years. There may even be a warning label on the service panel advising of the hazard.
Best!
The 410A is going to be banned next year I understand. If the system is installed right there should be no leaks ever. They use these everywhere in the world except in America in very small amounts.
I like Clark but so much of the information in this video was wrong
and teaching people about things like this when you clearly don't know enough about it yourself is irresponsible and potentially dangerous.
It's not rocket science. The directions for these things are great. Watch some you-tubes and save thousands from rip off HVAC companies...
Thanks for a great introduction video to mini split installation. Here in Portugal we have 3 in the house, all different sizes adapted to the area they are serving. There are millions of these things installed in this part of the world.
Perhaps of interest to someone is that you can read from the specs if the unit is relatively more efficient in cooling or heating mode. Look at COP (coefficient of performance) and EER (energy efficiency ratio) to describe the heating and cooling efficiency of the air conditioner
Also, these numbers should be adjusted for your location's yearly average winter/summer temperature.
Great to look for units that fit your needs and it is very likely that one type will do better in Florida for mostly cooling and a totally different one for mostly heating in the north.
Our needs are 95% heating during winter and we get about 5kWh of heat in the house for every kWh of electricity we buy from the grid.
On this side of the pond we also have time-differentiated tariffs so heating/cooling at the cheapest time really pays off.
An interesting comparison I did when getting the units 5 years ago was that compared to firewood ( about 150 USD / ton and a kWh electricity at 30 cents here) burnt in a very efficient stove (93%) the mini split units actually did beat the firewood by a fraction on the night tariff.
Still have to finalize optimizing solar panels / possible battery/ selling back to the grid numbers and what is the best combination.
The early estimate looks like "as many panels as possible", a smaller battery bank if any, and selling the enormous surplus generated during summer give the best overall returns while having "free" daytime A/C, pool pump, etc.
Just like Clark´s ultra-efficient boat AC heat pumps and solar are awesome together.
Cool site for getting yearly solar data for your location anywhere in the world:
globalsolaratlas.info/map
I do not know if you have any tax credits etc in the US for installing these things but it might be worth checking out?
As with most things " government / IRS " related it likely takes far longer time to understand the forms and red tape than it took Clark to install his unit...
Thank you for the installation video Clark, The next mini Split I will install myself!
Thanks great comment
I think you may really like next week's video.
I talk about a DIY idea to make these things much more efficient
@@Clarks-Adventure Looking forward to next week!
A Clark efficiency improvement is always interesting.
Thankyou ,really good demonstration ,l will head down this path too l think
Tee, hee, hee hee Hee Hee Haw Haw Hawww HAWWWW !!!!
Looks like the same unit as Mr Cool sales I think they are all being made in china
I could believe that. Lots of that going on
What do you think about installing these on a motoryacht with the condenser under the flybridge helm to keep it out of the weather
People have done it. Cheaper than mine but burns more power
@@Clarks-AdventureI was thinking more for the main a/c. Use a mini split for the day and your unit for the aft cabin to sleep at night
Sure
Think this size is 1200watt ac so add inverter loss that's a lot of solar. The 24-48volt water exchange system will be more efficient.
The inside unit is ok marine, the outside is going to rust rapidly if salt.
Yep.
👍😎
I love mini splits and I guess eventually we will have a design that works great on boats.,
My current gold standard is to run A/C either for the last 4 hours of your nightly sleep, or the full 8 hours if you can afford it.
Alternatively you could run 4 hours at night and another 2 hours for a midday nap. And as we get older, we love napping.
And with the sun high in the sky, that might just be perfect
I see you decided on a new channel name. It’s good.
Thanks.
Now I hope people can still find it
Capt Rick, forget his tube channel name, has one on his sailboat his wife loves it.
You work fast.
Thanks
If you don’t have all the tools you have, what would the total cost be? I bought a 12k MrCool unit from Costco for $1300 and installed that.
Like an extra $150 I think. That's going harbor freight or Amazon/EBay
I have some links in my Amazon store that I set up for my boat refrigeration videos. Clicking one of those would be nice for me
Europe is mainly mini splits and technicians do install them :-))
Great to hear
There are a number of name brand mini splits such as Daikin and their effective SEER ratings on their inverter tech units can hit into the 30's. The larger ones can support 8 individual air handlers/zones. They've made a lot of progress over the years with them. A number of manufacturers though only allow the full warranty if the unit is installed by a licensed contractor and will either reduce the 10 or 12 year warranties to 1 or 2 years or even void it altogether if you install it yourself.
Best!
It's illegal for non licensed technicians to work on refrigerant circuits.
There's a number of American channels who show how to install them but the quality of the equipment and the work looks piss poor and gives potentially dangerous information.
Do yourself a favour and just pay a professional.
A well installed split system can/should last 20+ years but a poorly installed unit could die in 6 months.
It really is a false economy and again potentially dangerous.
@@tommyt4062 It actually is not illegal for you to install what is considered a packaged/pre-charged unit as long as you follow the local code offices requirements. Most often that will mean on a replacement that you have a licensed refrigeration technician evacuate the old system before removing it.
As the pro-installers go... The last two companies I hired to do a full install had all the licenses and certifications however they did such a poor job it left me wishing I had done the work myself. Mangled up the breaker panel forcing the cover on since they were not neat about routing the wires, didn't seat the breakers correctly and didn't use any NoAlox to prevent corrosion on the connections making it so that there was a voltage drop from the poorly installed breaker. Air handler was slightly different in proportions so instead of using structural material to support it on all 4 sides they installed it slightly crooked and used duct board hidden by a ton of mastic to hide the fact that structural material hadn't been used.
When I brought this to their attention all I got was a Tour of Egypt via the River DeNile and then was Ghosted despite speaking to them decently without making threats, using foul language, etc.
They weren't the cheapest so I paid the premium for a quality job using a large firm but didn't get it. Code inspector didn't want to actually do much of an inspection either so that part was a joke.
I ended up cleaning the installation up myself fixing the issues in the breaker panel and adding the required structure to support the air handler.
Again on a packaged/pre-charged DIY specific system its not technically illegal if you follow the rules. Yes some Code Offices make it more difficult than it needs to be but even then most will work with you.
Best!
@tommyt4062 except when it isn't.
You have a great video here. I like the way you explain things, clear and simple. This model does not come with a much of a warranty. So if something was wrong with it from the factory (china) you might be out of luck. But getting back these things are great. Even the 2 ton is really inexpesensive to a house AC. Our whole house AC is $14,000.00 to replace yes 14 K. I just installed a mini split and it cools everything down very very well and the install is easy. In fact the 110 models are really easy to install. Anybody who is a little handy can put these in. I highly recommend mini splits. Best item I have purchased for our home.
You really don't need a warranty anyway, if anything happens a few years down the road you buy another one.
I also consider a Chinese warranty as a piece of paper.
@@Clarks-Adventure I agree with you but some are sold on Amazon and they don't play.
@@robertgregory2618 What if it's broke the day you install it?
@@wanaraz If you bought it on Amazon or even Temu who often is shipping to you from a local Amazon warehouse you get a pretty easy exchange. With Temu they even pay all the exchange shipping on the first item so it only costs you time. On big heavy expensive items that qualify for free shipping by themselves your best off to put them on a separate order.
If its broken out of the box then that is fairly painless if you do your research on the vendor.
Best!
New air-conditioning now cost closer to $10K.
Wow
So a few of these scattered around your house not only saves a load of money and power but gives you redundancy. If one fails just open some doors until you get it fixed
Zones in houses without ducts with losses. Way better than the older quad systems also.
Yes they come with timers.
How hard is it to have the bedroom come on at 9pm. And off in the morning.
Reverse for the rest of the house.
In the Tampa area that would only be a smaller low SEER bargain system. I just went through this last year and $10,000 met the minimum SEER requirement and that was on an easy replacement with the air handler on the floor within 10 feet of the entry door and not up in an attic plus they did not have to run any new refrigerant, drain or electrical lines as everything was already up to current code.
Best!
@@Clarks-Adventure The greater benefit, if you're willing to upgrade some aspects of doors and their jambs is that you can cool or heat only the areas that you need conditioned, adding savings to the savings that you are already calculating. Additionally, you can add a room to your home and not struggle with re-ducting. I'm sure that I could come up with a dozen ways that these are a better option than central heat and air but the main one is that there is no real benefit to having central heating and air over having these.
Demystified a mini, good. I'm looking at possible seer30 though doubles the price. Our power cost is expensive in most of California. 9k btu heat pumps have really come down in price. 12k are not much more though keeping a high seer is more $ Contractors are now advertising they install them, better than not working, the public knows what they want now. Many years ago out of country they were everywhere and shamed our lower standards. I have noticed the 208-240v tend to be more efficient than 110-120.
Absolutely. I first saw them in Central America.
They are the right idea
Just be mindful that the 30 SEER are usually inverter units and more prone to low voltage, surge and lightning damage so be sure to have a good active lightning clamp on the panel to protect that inverter AC unit. I'm considering also getting buck and boost transformer to correct low voltage from brownouts.
Best!
I would get a little bigger than what you need. The 220 is more efficient but you will probably need an electrition to set up the power.
@@wanaraz Yes, only a little bigger than what the formula dictates or you can end up with a damp house since when your AC unit is too big it short cycles and doesn't usually dehumidify very effectively. Then you have to get a separate dehumidifier wasting energy and loosing some if not all of the extra efficiency you paid for.
110 or 220 wiring is wiring so if you are qualified to do 110 then you should be able to do 220. The only difference is instead of L, C and G you have L1, L2, C and G.
That said if you are uncomfortable with the thought of working with 220 have an electrician do the work for you and see for yourself what the differences are.
I grew up when they taught shop and home repair in the public schools plus my Dad had his Masters in Electrical Engineering from MIT so we grew up working with electricity, building Heath Kits, making our own insect zappers, etc, etc, etc. We had well qualified mentors at School and Home to guide us.
Dad would say "Electricity is your best friend however even your best friend will eventually turn on you, often with painful consequences, if you don't show him respect and take advantage of him too many times."
Best!
Nice thing about mini splits. They don't actually cycle. They throttle down which keeps that issue from happening all together.
Ya know Clark, if you read the instructions you automatically lose your M.A.N. card.😂 (That Men Against Nowledge). But seriously you've got me thinking about one of these for some of my apartments. They don't have A/C right now and at $500 each I could pop for a couple for each apartment. Now the where to put the compressor units. Just a note on the Harbor Freight gauge sets. If you look on the Internet at the various gauge sets available they are almost all identical to the Harbor Freight sets except for the color of the plastic covers. No need to spend lots more money for some name so called name brand. Keep the good stuff coming.
You can stack 2 compressors on a strut frame, you can ground mount the frame or put it on the wall with the mfgr's recommended clear space offset from the wall. I've seen them mounted high on a wall for flood purposes but you'll need ladder(s) for install & maintenance
@@EngineerMikeF Thanks, that's something to think about.
I have seen the compressors on the roof. In a hot place though they should be out of the sun.
Uhh....did you create more work for yourself?
These split units usually come pre-charged. They are a little over charged to compensate for the line set. Thete will be a tiny bit of atmosphere air but you can easily purge that during hook-up. It's just- hook up the lines and open the valves.
Yep I cover that near the beginning.
Ok!
I'm rewatching it.
@toddtavares7386 Is Tavares your name or town. Just asking because there is a town with that name near me.
I imagine it's your name
No, Tavares (I believe) was named for explorers/traveller's that cam up after landing in modern day Brazil. My recent ancestors emigrated the US from San Miguel in the Azores. I am sure I share some distant ancestry though.
I noticed SEVERAL steps you skipped right passed without even a comment.
1) Did you install the inside unit on an outside wall?
2) You never installed the hoses to your inside unit.
3) You never installed the condensation drain hose to the inside unit.
4) Those don't look like the nice white rolls of hoses that came with your unit.
5) The electrical was even inside a conduit painted the same green.
6) What's the distance between the inside and outside units?
He just replaced the unit.
@@RussellHank-t3t
I've never heard of mini-splits until this month. I assumed they were a VERY new thing. You talk like they're kinda an old thing if he already had one, wore it out, and needed to replace it. This was the 1st installation video I ever watched on it. He simplified it so much he actually covered nothing to any real detail other than using that pressure gauge and vacuum pump. Even a complete neophyte like me could tell he skipped steps based on everything he did.
I'm hoping that a mini-split would work in my house, but none of my questions for my application were covered because all those "assumed" and skipped steps were ignored.
@theTeslaFalcon I saw my first one in central America back in 2001. Your not knowing about them doesn't make them new.
The last one in this location was lost to a wiring error where 220 was momentarily presented to the unit. The magic smoke all leaked out. Cheapest easiest solution was to install a whole new unit as I got a video out of it.
There really isn't much to install one. Yes I left out drilling the hole in the wall. If you aren't up to that don't do the project. I concentrated on the only scary steps.
Big point is no one here on this channel is trying to cheat you. Calm down. What do I have to gain? If you need more information keep looking. Or hire a HVAC guy to put in a big system. I'm sure you will get something that works for your 15k.
Just please don't bring your bad vibes here.
@@Clarks-Adventure
The beginning made it seem like it was a new install, but then you left all kinds of obvious questions unanswered. Parts swapping is always easier than new installations.
If anything, the "cheating" is I watch your channel for boat tech tips and you're doing land-based stuff. U ever going to install a mini-split on your boat?
@@theTeslaFalcon It was a new install
. He installed a NEW mini in place of an old mini.
