Purchased: August 2023 - still works GREAT!I kzfaq.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

Been researching mini splits all week looking for some to the point, clear, concise info. FINALLY found it. Thx.

Thanks. I went ahead and ordered a 18000 BTU MrCool unit at Lowes after watching your video. MrCool sells units without the pre-charged lines for about $700 cheaper than the pre-charged line units. Also, the pre-charged line units had 25 feet of copper and I only needed 16 feet that comes with the non pre-charged unit. The condensers are still pre-charged, just not the copper lines. I could not get any HVAC companies to vacuum the system. They only will do it if they install the units. I was replacing a 14 year old mini split that I installed and so I was not going to pay a HVAC company big bucks to install the new unit. I ordered the Amazon pump, hoses and adapter that you linked to in the description. Thanks for the great video!

This guy is a natural at instructional videos....! Highly recommend watching this for any mini-split install...! Great job...!

Man, big ups to you for making this video. This was my go-to for my installation. There were little things you breezed through, but I figured them out; and anyone with half a brain ought to be able to with some additional research. You saved me 2800$. And no, I'm not tendering a check to you for 2800$. But I do thank you from the bottom of my heart for making this--it's one of the clearest, most concise installation videos on here.

Great job explaining best I’ve seen so far. You made it real easy to understand thank you

This is soooo helpful. Thank you so much for this video. I was on the fence about ordering a minisplit and installing myself but was worried about the vacuum portion.

Thank you so much for this video!!! My install went perfect because of your generosity!

Great job/video for DIY homeowner installs. Couple things from a PRO. Leaving your flare connections buried in the wall is asking for trouble. if you ever develop a leak down the road, you would have to tear the wall apart to fix. Also, before vacuuming you should always pressure test with nitrogen(300-400psi), followed by a quick soap bubble test. if no bubbles are found after 5-10min.....then ill hook up the vacuum and pump down(you should be using a micron gauge and getting the unit below 500 microns/Timed rise test). W/o doing this, you still have the possibility of small leaks, and then, at the end of summer, after everything has been buttoned up, you notice your cooling just isn't as cold anymore. week later, and its not cold at all and the lineset is frozen(Newer mini splits all usually have low refrigerant sensors and will not run when the unit is not above a certain threshold, so it most likely will quit before the lines freeze up). Mini splits are so easy to install, which is why your seeing them marketed as DIY projects more and more, but there still are a couple things you have to get right on first attempt OR its a pain in the ass. I always recommend the flare tight gaskets when a homeowner is doing it himself. Would also recommend waiting for the flare tool, rather than leaving the coiled up lineset tucked up behind the condenser. just not a fan of how it looks aesthetically and I've seen way to many people, kids, and gardeners that have yanked on it, hit with lawn mower/weed eater, accidentally stepped on and kinked the lines and not the system has a restriction. I got called on one where a boy just literally pulled so hard on it, it busted off and he got lit up with refrigerant in the face. Anyway, now I'm just rambling, don't mean to take anything away from you brother. Great DIY for first timers video, covered a lot of stuff people should know. awesome job man

Great video! Just a note, those screws are for mounting the caddy for the remote.

Thanks for the excellent video. Just finished my install and it went perfect!

Best Senville install I've seen! Thanks for the info!

Thank you, nice video. I just ordered one of these for my bedroom. I’m getting rid of the big bulky pain in the ass central air unit. If this works out I plan on putting them in all my properties.

I drill a 3 5/8" hole and slid a 3" PVC pipe long enough and sloping down then I caulk both sides to keep bugs and water out.

And... I'll be right back. Installing one of these systems right now.

Watched the video 4 times an I enjoy every bit of the information I have install mine thank's for the video

Just ordered mine and will DIY myself your video made me a pro :)

Nice video I really enjoyed it I watched the video a couple of times already great job very informative

Thanks for posting, Just got mine and unpacking things. Having to add a new sub panel as I'm out of breaker room. Also it's to dang cold outside right now. Speaking of cold- I sure hope you opened the wall back up and re insulated. !! I was expecting you to spray foam insulation in there or pack it with Fiberglass. You didn't seems to even seal around the pipes with silicon. I'm not a professional but I've watched a few of these installed by qualified people. Another important detail was you never mounted the unit to the concrete pad. Most would use some rubber bushing and lag bolts. Your unit could fall over in a windstorm or vandalism.

Excellent video and straight to the point. This is very helpful!!

Great simple and to the point. Clearer than any other video I've seen. Explains the vacuum stage really well

Hey Thanks for the video ! Appreciate it, getting ready to install one myself. Just wanted to make one comment about a tip I picked up from another guys installation. Regarding the extra length of copper cooling pipe. You should never let the extra pipe rolled up like that because that creates areas at the bottom of each loop where the coolant can collect and pool up. You don't want that. Instead, he suggested that you unroll all the extra piping and run it for example up and down inside the wall, or run it up and then over in like a l-shaped pattern. That way you avoid those potential pooling spots in the pipes. Or even better cut the extra length out of course, but you have to have the flaring kit, etc. Thanks again for the vid.

Thx a lot. It helps to understand how it can be installed (better than an installation manual !)

Thanks for showing how to install a heatpump. Now I am going to do one for my garage.

that was EXACTLY what I was looking for. thank you so much.

Very helpful and calmed my nerves at being able to do this myself. Thank you!

Hi thank you for post this video. I wanna ask you what is the sice of the drain line because I set one and just came with the factory one a short one so I have to attach another piece, thank you

Great video , great explanation straight to the point ! awesome

so first we need to open the valve on hose connected side after connecting the vacuum hose (this was not shown on video) then close that valve before turning off vacuum pump (also not show on video) then open the High side valve(the one without the vacuum hose) then again open the low side valve and in last remove the vacuum hose, right? one thing more, what if entire Freon is being recharged then do we also need to open the high side valve in addition to low side valve for full vacuum of evaporator, condenser and line set?

Thank you for sharing, very informational and helpful.

Great video, Senville instructions should almost be ignored at some point because they are misleading. the scematic with my unit showed how to wire a 110v unit while I had an 18000 btu 220v unit. The quick shot of your wiring saved me a lot of time. This unit is pretty much diy but people take your time. I had to order the longer 25ft lineset. unit was installed in a vaulted ceiling situation and I had to go through about 14 ft of attic and out the wall and down. I pitched the wiring and drain bundle down before going out the wall for proper drainage. Quite a bit of water goes through the line as I am in a humid area.

Bought mine! I’m gonna start this! But...I’ll be right back.

Great job, thanks man.

Helpful! Thanks!

Thank you for the exact and clear explanation

Thanks . Excellent.

Do you need to bolt the unit to the gray base ? What if I install it on a roof, do I need to bolt the gray base to the flat roof?

Thank you, do you have more information about the pad ?

Thank You for your help

Thanks again!

Any idea what would cause a P4 error code?

thank you

I did the same thing with my senville units, I put the line set inside the wall, didn't want to see the channels outside.

Does the indoor unit have the bend support on it ,just saw it on video ???

"And I'll be right back." 😀

Nice video. I'm in Canada so we're not fortunate enough to get vacuum pumps and gages for less that what it would cost to hire a HVAC professional to commission the system.

Can you tell me what's that mean P4 they show on the unit

Good work

Are you going to leave the 30ft coiled hose behind the unit? Why not cut it to size?

How do the cheap Zeny HVAC gauges work, any good? I watch a video on cheap gauges and the guy showed that the hoses on cheap sets are poor.

Nice job

Hello question what size the breakers you put in this unit

I’ve noticed a lot of these do it yourself mini split videos don’t go into great detail step by step in wiring from the electrical panel to the unit. What the breaker looks like, what size breaker, how many wires what size wire and how it’s properly installed so no one gets electrocuted or shorts the system out

Anyone have experience with a 36,000 BTU version in an auto shop environment? Is it enough to at least cool down a poorly insulated building with 18ft ceilings?

Thank you very much

Good overview but I would have like to see more specifics and the stuff that is actually difficult with this installation. How tight to tighten the compression fittings, how do you setup your vacuum gauges, how do you measure for mounting the indoor bracket for proximity to the hole in the wall....

Good video.

You didn't bolt the outside unit down?

I join others in thanking you for posting this video. It takes the unknown and concern out of this type of AC installation. I have one question: How flexible are the lines? Can they easily bend (without kinking) from, say, and 4" framed ceiling to a 4" stud wall? Since that's a pretty tight transition I guess I'm trying to determine how tight a curve you can put in the copper lines. Hopefully that's something you can answer. Thanks again.

Did you install the air filter in the indoor unit? How many filters you got?

This quick video is better than the entire manual and the customer support that doesn’t answer.

Awesome guide man, cleared some things up for me, now I just need to figure out about the quick disconnect box setup and I should have my bases covered.

One of the best I have seen. I am curious however on the 220 going in to the outside unit. I saw black and red L1,L2 but didn’t see where neutral white goes. Thanks

Thank you for showing your step-by-step process in the mini split A/C unit. One thing I would like to know. You didn't show any interior electrical outlet on the inside wall of the house. Should there be an outlet inside? Next, the interior electrical outlet, probable a 20 AMP to match 115 or 220 Voltage would be the same for a freezer to be safely plugged into?

How’s it working 2 years later? My understanding (from another KZfaq video) is the senville is built by the same manufacturer as others like mr cool. The only thing I haven’t done yet is flaring. I prefer to do the non diy (from mr cool) so you don’t end up with the excess line set. I bought all the tools when I did my central ac in my old condo so I have everything but a flare kit.

Thanks

I already have a senville unit in my home, but it was the cheaper version, it's 12years old and not cooling properly anymore. I think I will buy a new one and replace it myself, seem easy enough, my wiring is already done, so it's disconnecting the old unit and replace everything with a new unit.

How is the system holding up? Still going strong? Thanks!

Great job, but I'm pretty sure looping the lineset creates an oil trap and thats frowned up in the instructions. It makes oil literally get trapped amd camt make it back to be "condensed" at your outside unit. They will still run, but not considered best piping practices in the field. Good job though!

Nice video. Thanks! Only thing I would question is why you didn't disconnect your vacuum prior to releasing the gas? The gas just filled the vacuum in the test set. The system was charged for a specific length of tubing.

Love the video. I could have a beer with this Sasquatch!! Thanks for the info. I would like to add some pointers.

If keeping copper coiled have to lay it flat not standing up

how many amps di it pull

what size wire for ac disconnect?

What size wires did you use from the power panel to the disconnect and then to the condenser? I noticed it was stranded. Great video 👍

how do you back the Freon back in to take the line set back off?

You say you need an adapter to hook the vacuum pump to the unit but you did not say what sort of adapter is needed (from what size and type to what size and type). Could you clarify that please?

how do you vacuum a 3 zone mini split i vacuumed each line but they all went back up to zero

Good video, if you were to cut the line set. Do you have to remove refrigerant? If yes, how much to remove? Thank you

Is your senville still working ok any problem

Great videos thank you !!! I'm still a little confused on the line vacuuming- if possible could you do a more detailed video on that process? I have questions like - when you opened the coolent valves and THEN unhooked the blue lowside vac line why didnt coolent blast out? and then just some basic process questions - how fo you know which line to use Red or blue - Ive never hooked up a vac pump (can you tell)? Great video They are really helpful.

Hi , their can you do all this without doing the vacuum test basically install everything then once done open allen wrench that let's out the freon and be good to.go ? I'm asking because I'm thinking of doing install.myseld it's not hard just dont have the tools to do the vacum test

I have a 4zone 36000 btu from senville. Requires 8/2 wiring. Do you have a video of one of those installs. I can't find one anywhere and of course the instructions are very minimal.

Are we not supposed to use 14-3 wire two hot wires a ground in a neutral ? I’m trying to install mine .. we’re is the nuetral wire spot ?

Make sure you open and close your gauges when you turn the vacuum pump on and off otherwise you will lose your vac

Senville would not replace a faulty unit after two part replacements.

Thank you very much for doing this. People like you make the world a better place. :) Overall, how have you liked the Senville mini-splits? I haven't see too much negative about them out there.

nice video, i need one install just like that, any suggestion? charlotte, NC

I got the adapter for the senville compressor. Did you install the schrader valve before vacuuming?

Every video on KZfaq shows excess coil lines set stored vertical a big problem for oil trap when instructions clearly state lay parallel with ground.

How do you lift the indoor unit off the wall mount after it is put on?

Mine came with a single screw holding the plate to the back of the inside unit that has to be removed.

I see you ran the lineset through a hole directly behind the wall unit....could you also run that line out the side of the unit through a hole in the unit? And does the hole have to be 3 inches?

Got the same unit and pad. Is there any way to secure the condenser to the pad? Thanks.

What gauge wire do you use from the breaker to disconnect box and from the disconnect box to the unit?

Can I use a plug with a mini split assuming I am not required by Code to tie into a breaker? If not, why not?

Never loop the line set in a vertical position it'll cause an oil trap and your compressor will go bad. You can loop them in a horizontal position however.

If you don't have a vacuum pump can you do a sweep from high side to low like you could on r22?

What did you do with the extra refrigerant copper line shown in 12:47? Did you just leave it there? Also, did you do it that way so you wouldn't have to flare the copper line?

so no flaring on these, just compression fittings?
