Really? Because he straight up lied about the difference in price and why. He tells you for 130$ you can do exactly what the Mr cool pre charged lines do but then he totally fails to mention that the refrigerant is gonna up the cost to what or more the price of the Mr cool lines are. You were deceived by his advice.
@LRN2DIY Рік тому
Sorry J M, but that’s completely false. There are no extra steps in this process besides what’s shown in this video. You don’t need additional refrigerant. When you attach and open the lines, the coolant that is stored in the condenser is let into the lines. If I’m wrong about that then my mini split is a miracle because it works amazingly well without having added any separate refrigerant. Just because some setups require that, don’t assume they all do and that I’m a lier.

As an HVAC installer in primarily mini and multi splits, this is one of the best reviews and intros to high efficiency heat pumps yet…and he didn’t even mention most mini splits today(2023) use half the power of a window unit and three times less than a central ducted system.

I installed a 18K Mr. Cool unit 2 years ago in my garage shop. I couldn't be happier and now spend more time in the garage than in the house. Even when it's 100 degrees outside, I can maintain low 70's in the garage (***note: garage has insulated walls, ceiling, and doors). As for pros and cons......here are 3 I wish I knew before installing Pros: 1) Adding the unit actually made me much more productive. Not only can I spend more time in the woodshop, but also have the perfect place now for car repair or home repair projects. 2) The mini split unit uses very little electricity. I run it all the time, and my electric bill is maybe only 10-20% higher than normal. 3) The heating function is almost as nice as the cooling function. I had almost bought a unit that just cools to save some money. Glad I didn't. In the winter when it's 30 degrees outside, I am able to hold the shop at......you guessed it.....low 70's. Cons: 1) The most difficult part of the whole installation was shaping the copper lineset against the wall and inside the lineset cover. I kinked mine and had to get it repaired. 2) The condensate line can be a bit of a nuisance if you have no place good to drain it. Having it constantly leak over a concrete slab leads to algae build up. 3) Unless you spend more money to get a multihead unit, the cooling and heating can be uneven if your shop has an odd shape. I have to run a small fan to get the air to equalize to the far side of the garage.

I have two mini-splits now. The first was a Mr. Cool, but the second one is a Senville 9,000 BTU unit. I saved quite a bit over the Mr. Cool model, and was able to do a no-hassle self install, thanks to watching your very thorough installation video! I even found a perfectly operating, professional-grade line-gauge set just lying in the middle of the street prior to buying the Senville unit. I was vacillating on whether or not to buy another Mr. Cool, but took the discovery of the line-gauge set as divine guidance to move forward with the self install.

I researched ductless mini splits for months when I was looking at replacing my RUUD central air. If you have a smart electric meter on your home go look at your KWH usage for an entire year. You will see that your heat-pump was sucking electricity all winter as well as summer. We live in FL so winters are not bad but the heat-pump was still running up the electric bill in winter. My electric averaged $300 month all year. Long story short I installed an 18K ductless in the living room / kitchen area, a 12K in the master bedroom and a 9K in the guest bedroom, all separate units and all inverters. I did all the work myself for less than $3K. This is for a 1650 sq. ft. house and those 3 mini splits are cooling the house better than the central air ever did. The best part is we can turn off the units that we are not using. At night when we go to bed we turn off the 18K in the living room and close the bedroom door. My electric bill has gone down from $10 - $16 a day to $4 -$6 a day even in August. I cannot report on winter yet because we just installed them this summer. The smaller units are using about $22 a month in electric and the bigger 18K is using about $25 month. Ductless mini splits are the best thing I could have done to this house. My old RUUD R-22 system is turned off but I kept it in case we need it for an emergency back-up system. Something I learned: Ductless mini splits are subject to damage from surges and local utility outages so I put a "whole house" surge arrestor in my main panel to help protect them. BTW good video!
@slavric Рік тому
You are my kind of guy. You people help us educate ourselves and I appreciate your effort very much. Thank you for that. I also bought all tools and learned to do all the job. I even have nitrogen tank and brazing equipment. For comparison: My neighbour installed 12kW heat pump and it cost him around 13.000€. I bought two 7kW inverter air condition units, 850€ each, copper pipes for exchanger (around 450€), nitrogen cylinder with regulators and brazing torch (about 250€). I invested some time in researching how to do it and connected it to an existing 2000 liter buffer tank. So it cost me approximately 2.500€ for 14kW heat pump. That is some real saving. But that's not all yet. Since I bought two split systems, I had two surplus internal units, since I only used the electronics from them. Then I got the idea... If I let water thru and start the fan, it should heat. So I installed one unit in my workshop and connected it to existing central heating. And it not only works, it works beyond my expectations. Also you can buy a "Smart Wi-fi remote control" for 10€ and control all your IR devices with it. This thing is so under-priced and useful, I can recommend it. I'm here to help if anyone is interested. Stay safe and warm. 💖

I think something else to keep in mind is the vacuum pump and gauges are the same equipment you need to work on your cars AC so it can be something worth having around. We did two mini-splits on our house this spring in Arizona and are loving them. I plan to install more after the summer for next year. Its so much nicer being able to cool the rooms we want to use vs the whole house when its this hot out.

Nice work. I did the same thing and switched the whole house over to three ductless mini splits. I did all the work myself including pumping a vacuum on the lines and flaring the line-sets. The worst part really was running the electric, but I was an electrician for 12 years in the military. A note on efficiency: Our electric bill here in FL went from $10-$16 a day in August to $4-$6 a day. I am expecting a drop of 1/2 or better in electric utilities. Our central a/c was an old RUUD unit R-22 and I don't think it even had an efficiency rating. Like you said..... we love it that we can turn units off and on in rooms that we are not using. At night we turn off the 18K in the living room and just the run the 12K mini split in the master bdrm and close the door. I did some calculations and it looks like our mini splits are pulling from $22 - $25 a month in electricity each. That is a HUGE cost savings. I would say installing these a/c units was the best thing I have done to this house so far.

One other thing to consider is the warranty. I purchased a Senville 9000 btu mini split and it was $800 and I also purchased a 3rd gen Mr. Cool DIY version. The Senville is supposed to be installed by a license HVAC contractor but I purchased the vacuum pump to do it myself. By doing this it voided my warranty. Both of my mini splits failed and the Mr. Cool was the only one that was covered under warranty. If you don’t use the DIY version, I would also recommend that you redo the flare to ensure a proper seal.
@greco2189 Рік тому
My Senville has started icing up after less than a year, more than likely a small refrigerant leak. But since I installed it myself, I have no warranty. A service call would more than make up the difference of a DIY Mr. cool, and Senville. When I purchased my Senville I also bought an extra 25-pound tank of 410a anticipating such a leak. The warranty is a big deal and a big roll of the dice.

I was surprised how low cost the Ductless units are at Amazon. I bought a 120 volt 12,000 Btu unit for my nephew's rental house, and actually mounted the indoor coil to a TV cabinet, and ran the tubing out the window, plug it into a 120 volt plug in the living room, and it is totally portable, so he can take it with him when he moves! I cut a 2XX4 that is the height of the window, and drilled holes for the tubing to go outside in the 2X4. Then sealed the window to keep out heat and bugs. He had electric 1,500 watt heaters in each room, and bill was huge last winter, and about $75 less each month this winter! Cooling is great, and it is nearly silent! It took us about 4 hours to install, I have been installing HVAC since 1984, so it was piece of cake for me!

I'm moving into a new place and the Family room has a mini split, I wanted to move it but found out that it was fairly expensive to have it moved so I ended up keeping it in place, I also didn't realize how expensive the unit was to have initially installed. I did research to add the ability of wifi to the unit and found something similar to the Sensibo you listed. My current house is very smart equipped and most of that is coming with me to the new place, we used the mini split one time and it is amazing how quickly it cooled the room, so far I'm impressed with it for the same reasons you list.
@Kangenpower7 Рік тому
It seems insane that some installers want to charge about $4,500 to install a mini split unit that they buy for about $1,800 from a supply house and it takes them about 6-8 labor hours to install. The "Off Brand" units that come from China or Israel, they tend to be about $1,000 including the copper lines that run between the two units. For my nephew, I was considering buying one of the traditional units, at about $1,200 and the lineset (copper lines between the two units) is a $250 add on. Then I found the units at Amazon for $719, 12,000 Btu and 120 volts. Perfect for his rental house! And so silent! Took us about 4 hours to complete the install. I have been repairing HVAC since 1984.

Unless he pulled out all the refrigerant into a tank and then weighed it(very doubtful) there is no way to tell how much refrigerant in in the unit. There shouldn't be any missing anyways.

I'm with you on the Fujitsu's, they seem great. I've got a client who's got 5 of them in a wood mill (I do commercial hvac). The outdoor coils get plugged up with saw dust and they trip on high head pressure occasionally, but they're all about 10 years old and are still running great under some pretty severe conditions, extreme vibration, dust, set at 68f most of the time. Best thing about them is I'm able to get parts for these machines still. That's what really scares me about the mrcool's. A 300 year warranty on the compressor doesn't mean much if the inverter board fails after 2 years and is no longer available, or they claim it failed due to voltage fluctuations, if you read their warranty on their site it seems pretty vague. Most failures I find I could attribute to one or two of those exclusions. I'm guessing that must be a part of their business strategy - planned obsolescence. I'm also guessing in a few years there's going to be a plethora of poor reviews based on their warranty.

Very good video. There's something else about buying those tools, you have them if you ever have to repair your unit or install another one. Mr. Cool is expensive and if it does have a leak down the road you'll likely have to buy new lines. I just bought a mini myself and the tools to install it, I also bought the offset flanging tool and the NyLog blue sealant and the line covers. I have flanging tools but the off set does a better job and at the pressures of mini's you want everything in your favor.

I installed a cheap chinese made Gree 3KW mini split myself in our bedroom fourteen years ago. I did my own pipework and bought a vacuum pump and gauges to set it up. It came with a normal 220v plug we use in the UK so there was no extra wiring required although I did get the main electricity supply to the house upgraded professionally as I also installed a large induction cooker in the kitchen at the same time. It's never gone wrong once in fourteen years and requires minimal maintence, only involving keeping it dust free. It's definitely one of the best purchases I've ever made. The air conditioning is on all night most nights from the beginning of June until the end of September. It keeps the room at a comfortable temperature at all times and is quiet enough it doesn't interfere with our sleep at all.
@randybobandy9828 Рік тому
Gree isn't actual that cheap. I mean the price is but the product is quality. I have installed a couple brands that are just green units with a different name and they have been going strong for 5-7 years now. I had a 3 ton Mitsubishi that definitely didn't cool as well as a cheaper (blueridge) unit that was also a 3ton. It was literally half the price at the time! $1700 vs $3600 for the Mitsubishi. I'm not super sold on Mitsubishi because the price is simply too high for whatever extra reliability you get. Pioneer/gree/senville/blueridge are all inexpensive and very good units. I have installed Single head units, double head units, and triple head units. So far all is good. I invested in really nice hvac tools that ensure a proper install every time like micron gauges/torque wrench set(not the same as a socket torque wrench)/ a nitrogen tank to pressurize the line too 300psi to see if there are any leaks before pulling a vacuum down too 500microns. You could probably get away with a cheap pump and gauge set but it could be a risk that you might have a slow leak Overtime but since I was installing many minisplits the proper tools where worth it.

@Kangenpower7 Рік тому
Grand Designs is starting to install ductless mini split heat pumps in their new units! It is a great upgrade. They put in a 2 zone 240 volt outdoor unit under the fifth wheel section, with the air intake on the drivers side. You have to be right next to the unit to see if it is running, they are so quiet! And the indoor coils are silent, as noisy as a very quiet refrigerator. The problem with the two zone outdoor unit is they require 240 volts to run them. Your other option is a pair of 120 volt units, with each being 12,000 Btu capacity. There are several suitable units, and I would suggest using both drain lines on the indoor coil. That way, if the unit has one side higher than the other, the lower side will drain out. I would mount the unit on the drivers side wall, and then run the tubing into a closet or down the wall into the basement area. That way the drain will work the best, and also hide the copper tubing the best. I think that Grand Designs is going to start using a 48 VDC inverter, and they are also recommending that you install a 9 kilowatt alternator on your towing pickup. So you will have two alternators. They then use a 15 KW battery system at 52 volts, and the alternator is rated at 9,000 watts, or about 175 amps at 52 VDC. I am not sure how large the wires are between the truck and the RV. They might be running even higher voltage, I just don't know for sure. If the alternator going to the RV is running 3 phase at about 300 volts, then #10 wire fused at 25 amps would be large enough, and still have a cord that is flexible. At the RV, the alternator output voltage can be reduced to charge the 52 volt battery at about 175 amps. So very large wire is required to handle 175 amps for 9 KW at 52 volts DC. Think larger than your battery cables on your truck battery. So the problem remains If you happen to love a RV park that has a 30 amp 120 volt power plug, and is out in the middle of nowhere. If you have plenty of solar power, that is fine, your inverter can produce enough power to run the ductless heat pumps. If you can plug into the 30 amp service, and run the battery charger to keep the 48 volt battery full, or at least partially full, then the inverter can run the 240 volt ductless heat pump just fine. But if you do install two each 120 volt ductless heat pumps, you could run them on a 30 amp service, and do much better than when trying to run a pair of 120 volt rooftop units. This is because the ductless units only draw about 1,000 watts when doing the maximum cooling, like when it is 80 inside and you set it to 70. Once the inside temperature and the set point are very close, say it is 76 inside and you set it to 74, the compressor slows way down, and the unit can use as little as 350 - 500 watts. So running a second one with a 30 amp power service is fine. If you are getting close to your maximum power draw, or the voltage is dropping, you can shut off or unplug your battery charger until there is a time, such as at night, when you can plug in the charger again. Or run a extension cord to the power post to run the charger from the 120 volt 20 amp plug. That can shift about 5 or 6 amps off of your 30 amp plug to the power post. Or if you can plug the ductless units into a 120 volt receptacle, then plug one into the RV, and the other into the 120 volt power post receptacle. I might suggest installing the outdoor units on a cargo carrier on the back bumper? Maybe you have a better location in mind?

Hi, regarding legal requirements in other regions: In Greece, where I live, smaller units come with a plug, so you don't need an electrician if there is a power outlet nearby. On the other hand, you need an F-Gas certification to work in refrigeration and air conditioning, systems charged with R407C, R410A or R32. That certification requires a refrigeration technician license. So you can't DIY them, legally. Also, in order to have a warranty, most units require installation and regular service by a professional.
@alerighi Рік тому
Also in Italy. You need to be a certified thecnitian to install one and you need to make a declaration of conformity of the installations when the job is done. Reguarding the plug, usually unit comes with a plug attached to them (I don't know if it's a requirement or not), and I've seen some situations where that had been used, even if the best option is to cut the plug and hard-wire it (better if on a dedicated circuit, but if not available to a socket circuit but with a bipolar switch). Also differently from the US the power is connected to the indoor unit that then sends it to the outdoor one (makes more sense, since inside you already have power and you have to bring only one multicore cable to the outdoor one, the outdoor unit doesn't have power when the AC is off since a relay in the indoor unit cuts the power and you don't have to make connections outside).

I do commercial hvac, and if it were me in this fella's shoes I'd stalk a commercial hvac van and ask if he's interested in doing the flairs and pulling the vac, or knows someone who is. Residential hvac guys can get in trouble for doing residential side work, commercial guys generally don't have to deal with that. Might cost you as much as buying the tools yourself, or just a bit less, but then you don't have to deal with the pump and gauges you've only used once, and will probably never use again. ...unless you're trying to start a new side hussle, then by all means go for it.

Other tips: 1. between 3 and 5 years you're going to need a new motor. The motors become off center, wobble, and that wobble extends thru the squirrel cage. Buy the replacement motor when you buy the unit because the manufacturers are always discontinuing models. I've got 28 I take care of in a lodge. Also try to get buy or download a service manual when you buy the unit. Some mfg's don't make them available. If you buy a replacement motor where the model has been superceded, make sure the connector is the same. Often the wiring will be different or the connector is a little different. Also, the shaft length seems to change a lot so make sure if the shaft length is different that you can still use it. My replacements had a shorter shaft (still worked fine) as well as a connector that differed slightly(shaved a little plastic off with a knife and they worked). 2. clean the filter once a month. Clean the squirrel cage every 6 months unless your in a dusty area that also gets rain. The squirrel cage gets dusty then wet creating wobbles as the muck dries unevenly. 3. Be extra careful when removing the plastic parts. It's always the kind of plastic that breaks before it gives. 4. Remember that they never stay as quiet as the day they are installed. I try to keep mine no higher that 42 decibels 3 feet away as long as there is no wobbling noise. Once a wobble noise starts, it will get louder. Often i can get a decibel reading in the mid 40's with a wobble, and in that case the wobble wakes people up not the decibel level. You can get a decibel app for your phone for free. I take the squirrel cage out to clean it but you probably could clean it while it's in with a sponge and toothbrush if you didn't have the time.

@AniBAretz Рік тому
Just beware of a flooded floor. The minisplit will seem to stop clearing humidity in the room, hinting that condensation is not draining through a hose to the outside the way that it should. Moisture which doesn't get through the drain hose builds up and begins cycling through the room until it finally stops draining at all and just floods the floor. Also, with time, it gets noisy. This is curable. Dust and debris settle in the drum fans inside the indoor part of the unit, causing turbulence, which causes noise. A bottle brush, for example, can reach in and scrape the inside of the drum fans clean. A vaccuum cleaner helps remove the loosened debris.

Once again you have to look at your area. If you live in Arizona or New Mexico a high seer number is a better option. Look at your sensible heat vs latent. High seer units remove very little humidity. This is why ducted systems are coming with a variable ECM Blower and a DEHUM terminal. When this terminal is deenergized the blower will roll back to 75% airflow thus turning your central air system into a big dehumidifier. All SEER rating go out the window at this point. If you turn your ductless to dehumidify or dry the same thing happens. the unit is no longer temperature controlled or has any SEER rating. If your air is dry enough you can run the unit at the same specs it was tested at. At that point you may consider a swamp cooler or a large coil with well water running through it. In PA we have a lot of humidity to deal with.

Gree makes compressors and maybe other parts for MANY brands. 38 SEER sounds like knife's edge, wondering if, like Li-Ion batteries, the performance runs down over time? More likely to fail?

2 minor corrections. 1 - the condenser doesn't pull air - it compresses the gas used to make the cold and pumps that cold gas through the inside blower unit. 2 - you can use the 220 outlet - it can make 2 (110) outlets and/or you can change the outlet connection type to most any other 220 style of outlet. Other than that, good video. I live in Central Americana and the mini splits are 99.5% of the ac units down here. They work great and are nice to not have to cool the entire house.

You missed the biggest advantage of Mr. Cool: the warranty. Yes, they're significantly more expensive, but they're also the only units that provide a warranty on DIY installs. I debated going the "buy a vacuum pump and refrigerant and do it all" route but decided against it because I really wanted the warranty.
@ericfranke1637 Рік тому
Actually, they say they will only warranty it if installed by a licensed technician.
@CyberlightFG Рік тому
I think, the units are mostly precharged. You just need a pump. That's important, because refrigerant got very expensive.

A couple questions, do you need a receipt from a licensed A/C contractor for the final installation to get the warranty? Is there a way to install a box "pre-filter" around the air intake for better filtration than the little plastic filter that comes with the unit? ( I made one for my window unit out of quilters fluff that has helped in my shop) Thanks for the link to the inexpensive vacuum and accessory equipment!

@randybobandy9828 Рік тому
Yes you need a licensed hvac to sign off on the Install. I never did and installed 10 or some mini splits and haven't had a single issue with them in 7 years. They where mostly senville or blueridge units and one Mitsubishi. I wouldn't hold my breath on a warranty unless you paid a installer to do the work.
@samTollefson Рік тому
@@randybobandy9828 Thanks for that, it gives me more confidence in doing the job myself. Did you vacuum down the lines? I haven't bought one yet as my old window unit still works but I called two local A/C companies and they both basically said no on final install and that they couldn't guarantee their work unless I bought the unit from them, when I said I didn't need a guarantee from them, they said sorry, company policy.
@randybobandy9828 Рік тому
@sam Tollefson yes I vacuumed down the lines. You want to get a micron Guage to make sure you pull a full vacuum down too 500 microns. You can get away with regular gauges but you might want to just vacuum down the lines for atleast 12hours then shut the value on the gauges are let it sit for a day and make sure the vacuum doesn't move the gauge at all. Ac install companies not wanting to install the unit I bought was one of the reasons I installed it myself. I did find a company who agreed to install the minisplit I bought but they tried to quote me $2400+ tax to install it... they where trying to charge more for the install since they couldn't make money on the mark up for the ac unit that they usually sell. I was able to install a 3 ton minisplit that I paid $1750 for(including the refrigerant lines and shipping) with about $300 in tools and another $75 in electrical. That would have been $6,000-$8000 from any local hvac company easily. A 3ton unit is a very large one that can cool a full 2,000sq ft home. You can buy a smaller one for alot less. Watch a bunch of videos on install and take your time doing it and you will be fine! The hardest part is honestly bending the copper line sets as they get pretty thick on the larger units.

In our house (Central Europe) the outdoor and the indoor unit (2.5kW split) the have a single wire that is plugged into a grounded 220V socket. Installation was done by technicians (coolant tube, wire connections, vacuum etc) but the entire electrical hookup consisted of finding an extra socket and plug in. This, being an efficient unit, does not use more than 880W at any point though, maybe larger units would be hardwired here too.
@mytuberforyou Рік тому
3:30 that disconnect is not wired to code. Can't use neutral as a phase leg, have to reidentify. Dropped wire gauge means your breaker and fuse if it's a fused disconnect need to be the lower ampacity. The data plates on most of these units are confusing because the manuals say breaker should to be 1.5x peak amperage which for a 18K BTU is typically like 22A but specs a 30A max circuit protection. And you also need a flare kit (Harbor Freight or auto parts store) and a tube cutter so you can cut the lines to length and flare the ends. Whan you buy literally ANY of the DIY kits it weill say in the manual "All electrical connections must be made by a qualifed and licensed electrician".- I don't know if the seller or manufacturer will use that as an excuse to avoid a warranty claim by demanding a copy of the electrician's invoice, so bear that in mind as a possibilty. Typically you are looking at $500-$800 for a new panel run with the associated wire, disconnect, and whip, vs. about $100-$150 if you DIY depending on how much wire you have to buy or if you can get 6' of flex instead of a whole $40 roll.

Darenator, While the National Electrical code revision in 2018 said that you need a 120 volt GFI protected receptacle within a certain distance of a HVAC outdoor unit, they do allow for a exception if you have one within 25 feet already installed. Oregon decided not to adopt that section of the new revised code, so it is not required in Oregon. Yet. Still it is handy to have a outdoor receptacle on the home. I put several on my sister's home to run Christmas lights! Just under the eves, so 9 feet off the ground level. When I installed a new HVAC at my sister's new house, I put in the disconnect, and a box under it with a 120 volt GFI receptacle. So she is ready when the inspector shows up, if it might be required in Washington. Anyway it is handy to have when running the vacuum pump. And the extra cost is only about $25 to install? I was able to connect the disconnect and receptacle box by running the wiring through the garage, even avoiding tearing up the drywall very much by installing a new double box inside the garage, just behind it I have the outdoor disconnect. So the 4" square hole that I had to cut into her drywall was filled by a double receptacle in the garage, and a 1" hole through the wall into the back of the disconnect finished the job, with no conduit at all. Just ran one 240 volt #12 wire to the A/C unit and 1 #12 romex to the power receptacles.

I've built cars, airplanes and done massive remodeling but the installation of my mini split took more than a month. It's a lot of work and requires electrical skills, fabricating skills, assembling the covers and then u have a unit you cannot remove easily for repair. In contrast, the window unit is done in an hour & when it breaks, you take it out of the window/wall and into the shop for repair. My mini is 18k BTU which is twice the requirement for the room but the time it takes to cool the room from 81 to 74 is < 30 min. I see little purpose to wifi other than bragging that u can turn the AC on before you get home. No Big Deal. Another important consideration is service after the sale. Make sure the seller has a tech u can talk to during and long after the install. My unit reqd a vacuum pump and gauges but I had both. The seller wouldn't honor the warranty unless an HVAC tech did the work so I took the HVAC online course, passed the test, and that qualified me for the 5 year warranty.
@randybobandy9828 Рік тому
I wouldn't install a minisplit without a micron gauge and making sure the line holds a vacuum under 500microns for atleast 4hours. Those gauges aren't accurate enough to do a proper job. A micron gauge is about $150 by itself. Torque wrenches are a definite help but not completely necessary along as your lines hold a 500micron vacuum you're fine.

@deek791 Рік тому
Pre-charged linesets are for folks who have no idea what they're doing. And pulling a successful vacuum on a closed system requires more than half an hour. The industry standard is less than 500 microns held for at least 15 minutes. You have to pull much lower than the 30 inches of vacuum referenced on a set of gauges. That's another mistake folks make when they have no idea what they're doing. These "DIY" systems, overwhelmingly, don't last long due to improper installation practices and techniques. Whereas professionally installed systems, installed with quality practices, often last upwards of 30 years of efficient operation. If you wouldn't DIY overhaul the engine in your vehicle, you shouldn't DIY an HVAC installation. There is SOOOOO much more to it than connecting point A to point B. Also, minisplits in a shop environment tend to be a nuisance to clean due to dust and other material clogging the head coil.

It's summer 2023, and the Tosot website says the unit is R410 Pre-Charged. Also, if you get a 110V unit (9000-12000 BTU), technically you can use a dedicated wall outlet. I'm saying this simply because I could not find a definite "NO!". All it says is that it needs a dedicated circuit breaker, which a dedicated outlet has. I happen to have a dedicated 20A outlet for a central vacuum unit in my garage and I'm giving this a consideration.
