Good stuff! Will certainly help w/our decision about what equipment to install in a new building. Thanks for your work!
110v and 220v will use the same power and thus your electric bill will be the exact same for both voltages. The difference is you are sharing voltage on two conductors instead of all on one. So 7amps on line 1 and 7amps on line 2 = 14amps for a 220v. Or 14amps on 110v. You get charged the same. 220 will usually be more efficient due to power losses in wire so 220 is the way to go if Possible.
Yes, you are right, the power is the same even if the amperage is double for the 120 volt. And you are paying for power. The losses in the wire are negligible if you have properly rated or over rated (i.e. larger gauge) wire. From my point of view, the only benefit to 240 volt is that you don't need as beefy a wire, since the thickness of wire is specified by amperage. The downsides to 240 volt is that you need two breaker slots in your panel instead of one, and the breaker is a bit more expensive since it's a double wide.
You're kind of right, Luke. If you measure current on the neutral wire in the 120V, you will have 14A and 0 volts. A better way of looking at it is P=I*E. Voltage drop isn't as big an issue since these types of units do not create huge inrush current and most of the 120V rated units are small with a relatively low current draw.
I understand the 220v is more efficient for the machine and will work better and last longer?
@@rentvesting More efficient, yes. Better? Longer? About the same.
That's wrong. Power is voltage times current. 220v vs 110v has half the current. If the current was the same, the power would be double...

Great video, very well explained in details. I was thinking of installing a cassette in a hallway but after watching this I will opt for another solution. Thanks!
Thank you Jonathan really appreciate you watching
Always like to find a New but older video never seen this Thanks
Hay taddy have a good day, hope you fill better today I'm always watching your video. God bless
So glad I watched this video. Installing a cassette in a ceiling/attic with possible blowback. The suggestion to block off vents will be considered after testing. Thanks!
Sounds great!
where the 110 version come in handy is if someone is replacing an old loud unit in an RV or camper, this is becoming a great option. not common practice yet but a few manufacturers are starting to put in as an upgrade
Good work and information. Take it easy on your hands young man.
Nice grow building!
Nice shop, I like you grow dude! I had a similar setup in Colorado but sold, now I just do HVAC/R. 👍👍
thanks man
That's cool that you noticed 😎
This is very helpful. We're doing an addition with 2 different heating/cooling zones and all my local HVAC companies are pushing traditional forced air but it doesn't seem logical to me. I've been looking into mini-splits but am not thrilled with the wall mount look. Nice to know about the 4-way cassette option for the ceiling. That might be an option. Thank you.
There's also a floor mount option I've got another video titled what types of mini splits are there
you should check it out
Wow nice job and explanation young man
THANKS
Great information…considering a mini split for my new RV build.
nice Carl Thank you for watching 👀 😀 Stay healthy Stay Happy 😊
I totally agree with you about the online mini split deal....people are always trying to pinch pennies an sorry when the unit breaks down
yes that's right
Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) czcams.com/users/postUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.
Very helpful, great video. Thanks.
Glad it was helpful!
Great video. Thank's for doing it.
Your Welcome thanks for watching
I'm Dwight I service Newport Beach alot of different issues with salt water love your sales video we have the same gift
Thank you my brother glad you're here
Great content Tad!
Thank you mark thank you for watching
Great Video. I would love to see an instructional video on installing a dual zone wall mount mini split in a 5th wheel toy hauler. Thanks
Coming soon!
love your shop
Thank you Earl
Thank you sir from North Carolina, mild climate not Florida but definitely not Michigan where I am from
Hey Frank thank you for watching my friend
Thanks for the super straight forward info. Whatcha growin in there tho
Cannabis and Veggies
I have wall units, I'm looking to add cassettes. One thing to keep in mind for everyone is drain pumps WILL clog up or break causing water to leak. You won't know till the wall or ceiling is wet. Also drain pumps are loud
Make a video on how to do your own electrical. Like breakers, why double pulls, fuses, gauge sizes. 😀👍
ok deal
The 220V version is a little more efficient than the 110V version, however the 110V version will not cost twice as much. The 110V version uses twice the amperage at half the voltage. Watts = Volts x Amps, so the wattage usage is mostly the same. Your power bill is charged by the kilowatt hour, not the amp hour. That being said I also prefer the 220V version when possible.
you are correct in that because your pay for KW the difference in amp would not make much difference, but you can only buy 120V up to 1 ton or 12,000 btus
Thank you for your videos.
I have a hvac and refrigeration company called Pioneer engineering and construction.
I teach young people, hvac , refrigeration, electrical and plumbing.
I like your videos .
Thank you
That is awesome! Thank you for watching my friend.
You have got good work place bro.
thanks that is my aquaponics grow facility
Awesome video & info , have you ever retrofitted one in an RV ? ? Have seen many mini splits installed on “you tube” in RV’s but only one with the cassettes installed . You should make an instruction video with the cassettes installed in an RV , New Horizons that manufacture 5th wheels are one of the few who custom install these but over charge customers. Thx again & very well done . 👍⚾️🇺🇸👏
thank you Bob I love the knowledge thank you for the insight I may check into this 😊
You really should , I’ve been in the market for a Renegade Super C RV & typically these Rv’s only come with regular ceiling AC units that are extremely loud fans while operating & inefficient systems . Many RV people that Boondock are going to mini splits for their efficiency low watts & using lithium batteries / solar to operate them . However there aren’t very many experienced installers that want the challenge to install these in RV’s . Check them out on “You tube” ……all the best & maybe I’ll have you install mine when I finally purchase my RV ! Lol best of luck 👍⚾️🇺🇸👏
One issue I see with the ceiling cassette in an RV is the depth of the ceiling. Unless you recess it down a bit. You would then need to retrofit some type of cover or trim around it. Lines could run up through the room then off the back or front.
There is a 12V system out there for RVs, one I seen has the outdoor unit, installed under the RV.
Thanks for the video, I was considering a cassette in my hallway near the openings of my 3 bedrooms, I can understand why you wouldn’t recommend, but if it was placed in the doorways do you still think it would be a bad idea if the intention was to keep all the doors open while running to try to cool essentially my entire upstairs?
Great information. We have two spaces in a 400 sqft pool house we need to cool and heat (Rio Rancho, New Mexico). Your product suggestions for small size 2 zone cassette mount would be great.
Hey James I'd be glad to help my friend
If you need my email you know what to do
Let me know Make sure you're signed in to CZcams when you join
Good video
True, the 220 volt units are more efficient, but I have 2) 110 volt units because of power limitations, and my power bill went down, they are very efficient even though 220 volt units are better. I have found that the difference in these units from 220 or 110 is very low.
I have a ranch and went with 2 12,000 btu 110 wall units 2 years ago. I have one at the end of my hallway (takes care of all the bedrooms and main part of the house and one in the living room). My first floor is fairly open and these 2 units work fantastic! I can even leave my 3 season room open most of the time unless it gets above 90 out. With the 3 season room closed I can keep the house around 70 even when it's 100 out!
Thanks for this video I’ve been providing ductless HVAC Systems as an option for customers and they have been happy with it. I have never done a cassette but was curious on more ductless applications like cassettes and floor mounts in the event I have the opportunity to bid an entire home. How can I become a member? I am interested in a copy of that booklet as well if possible. Thanks for all that you do. I’ve been working with my father in the industry for years but my exposure has been limited to residential service/installation. Videos like yours have been an essential staple for building my knowledge base. Even though I might not have a job the requires a cassette for example, at least I’m able to become familiar beforehand for when/if that time comes.
That is awesome so glad that you have been working with your father and glad that you had the opportunity to install ductless equipment which is the future for now
I will send you a link to JOIN and then I will give you my email and send you the guides to help 😉
Same here, been working with my father since I was a kid. I've done hundreds of mini splits, mostly wall mount an a few ducted. Never done a cassette though.
You will have no problems
Glad you've been working with your dad that's a great experience
Another Tad! :) good stuff
Great info. I have a flat roof above my ceiling, are there any issues? I assume there are more than 22" between ceiling studs, so ceiling min split fits in without removing support studs. Loos like best location would be in center of room. I also have an adjoining room (kitchen) where I could use a 2nd split. Both can run off one outside unit? Thanks
Great video. I am in the planning stages of a mini split install for next year. I want to get rid of my window units. I have a couple of questions, can you mix wall units and ceiling units on a multi zone system?
Do you need a handler in every room? My upper level is about 700 sq ft, 3 bedrooms that share a short hallway. It would not be practical (and expensive) to put a handler in all 3 bedrooms. I am thinking a 12k handler in the large bedroom. Maybe fans for air flow?
Thanks for the video. I just got a quote from a "pro" for over $8k to purchase/install a split for my two-car garage. I almost threw him off the porch. I think I'll be going the DIY route because I can buy it several times over before approaching the quote.
I can help you save money and I'll teach you how to DIY your new unit join and become a level 5 member send me an email tadfuller1@gmail.com
The greed today is astounding and disgusting
@@TaddyDigest Thank you for the offer. After just a little research I'm pretty comfortable with the install. The Pioneer unit I just purchased came pre-charged, and I ordered a vacuum pump and gauges. My only holdup now is finding an electrician to wire my disconnect (wife's insistence), but they don't seem interested in coming over for a small job. Looks like I'm going to do that myself as well.
@@TaddyDigest P.s. Sorry I'm just now responding. I never got an alert on your message. Only the other gentleman's.
Anyone with just a little DIY skill can easily install these. The rates the 'pros' charge are pure robbery and there is no way to justify the cost. Why worry about a warranty when, as you stated, you can just replace the entire system yourself for 1/8 the cost of the install.
You also don't need to become a member here to learn how to install these from this guy. There are probably a hundred free videos here on CZcams showing you the exact same thing.
Great. Idea. Which one would you recommend, the cassettes or wall mount? What’s the cleaning service cost for both? Warranty’s are important for customers. Lastly, what systems is better or recommend, Daikin or Mitsubishi & which one has the better warranty? Thank you.
That's some good tips here. I'm thinking the ceiling cassette could have more issues laying flat with many people installing those in the attic hard to access if they start sweating or leak. Maybe I'm wrong would like to see a 1 year test on these ceiling cassettes
Mines great there's a water pump
attic access is mute. if done right first. as there is no reason to ever mess with it. unless it just flat out fails.
i would like to go this route on my house, 4 ceiling regulators. (two bed rooms on the hot side of the house, two in the front of the house, living room, dinning room, kitchen, no walls here). room to work up top.
draining is also not a problem. might not even need the pumps? each regulate would be within 7 foot of a open drain. less if in a wall. all pending how built.
and then just insulate best to prevent sweating. no mater your location. worse case a simple air water pump. from a aquarium shop. they are quite, last dozens of years, cheap to operate. biggest problem with any drain is fungus, mold, plant growth. plugging up the drain.
I have a 25' x 30' fully insulated new all metal shop. 12' exterior walls and a 17' height ridge. No ceiling, just an insulated roof. Right now, 2 small 5,000 btu window units are keeping it cool, and a pedestal shop fan to move air around. However, I'm in Texas and it gets over 100* in the summer, and the 2 small window units struggle to keep it cool. So what size wall mount mini split do I need? I have 110 and 220 available, but every dollar I spend on my shop is one less dollar I can spend on my 56 Chevy I am restoring! ;) Thanks for your help!
We're thinking of installing a ceiling cassette unit in our parc camper instead of that very noisy, inefficient air conditioning unit (I like to call) "Big Bertha" . Taking advantage of the ducting that runs through the camper. I figured why not make use of that convenient feature we have. What do you suggest? Thank you
Can you do explanation to ducted split & its full installation and duct design and consideration? Thanks
Hoping to cool my 850 sq ft garage with a mini split of some kind. The in ceiling unit would be better for my application. It is a regular house though, not a drop ceiling. What ceiling mount units might be good for my garage?
I am highly partial to wall mounts. I hate the ceiling units, but they do look a lot nicer.
My pole barn is 28x40, spray foam insulated and I would think I center placed cassette in the trusses will distribute heat and a/c better than a rear wall mounted wall unit… 24k btu? Any thoughts… near Atlantic City, NJ
what do you think about air to water heat pumps. looking to use one to heat heat exchanger for plenum on havc system to heat house or rad floors will they keep heat at 30 degrees and below / without heat strips /how much power / any help would be great thanks
Can you turn the pump off or can you get ceiling units without pumps? Ive got enough elevation from the condensate outlet to my vent stack or roof soffits to drain passively. Would prefer not to not worry about pump maintenance
Nice video I install a lot of mini splits
Samsung and Mitsubishi
Was interested in the sizing cheat sheet you showed could you send it
Can the slim/concealed duct multi zone systems go into a bigger house that’s broken up to lots of rooms? I like the idea of having zone control. Thanks!
Yeah of course
Can you help with installation of 220v system in an Rv? I’ve seen it done before. I was thinking of duct system to tie into the existing in basement. Or these cassette units and reframe the existing Rv acs in the roof. They have done also in some high end models.
Just an fyi from an HVAC contractor: the vent for the condensate drain goes AFTER the p-trap. The whole point of the trap is to prevent air from the attic or other unconditioned space pulling into the unit adding load and possibly preventing the water from draining properly.
thanks for the Knowledge
Throwing in 2 cents, a vent's first purpose is to protect the trap (from siphoning).
Great video! Question: can you mount the ceiling unit sideways in a wall? Or is there a inset wall unit made for that?
I have a spacious interior soffit into which I’d like to mount an inset ductless mini split (rather than having the ceiling penetration into my vented, unheated attic space). Thanks!
You can't mount it in the wall, the condensate trap needs to be facing up.
If you search for "LG Art Cool" you will find a picture frame that hides a wall mount mini-split behind it, the trick will be finding a place that has it.
Between the two of these options, which one would you choose for a rental property? I am not as concerned about the cost difference as I am about neglectful tenants. Would the ceiling cassette option operate longer without maintenance than the wall-mounted? As a landlord, I would try to schedule yearly or bi-yearly maintenance visits to ensure the AC is clean and working correctly, but I cannot depend on a tenant to do any of this maintenance.
That's a good question
I will do a video to give you more insight
Great....great video! Finally a video that's to the point and informative!
I live in Montreal Canada and I was about to install a mini split system with a wall mount unit until I noticed that I didn't have the height clearance to install it, and I can't return the unit because I bought it last year and they won't take it back. So my question is can I buy just the ceiling cassette unit and install it to my existing outdoor unit and if yes can I buy any brand ceiling mount unit?
Thank you for your video and your time.
Mark
Hey mark thanks for watching the video I really appreciate you watching watching I would say you probably can't install a ceiling cassette with your existing outdoor
Not unless you're existing outdoor unit is the same brand
@@TaddyDigest Thank you for your response. I've found another solution, I was missing 6 inches from the ceiling for the air to circulate so I decided to cut open a portion of the ceiling without touching any joist. Now I will close up this new clearance with drywall , plaster, paint and then the original wall mount unit will fit. Once again thank you 😃
Oh that's awesome. great news. So glad you found a way
I brought my unit off line and can not find any one to service to you have any recommendations Savannah GA area
If the rooms are on the second floor do yu set the condenser on the roof
When I look at the square foot per BTU chart, does the volume play a part? I am looking to install a heat pump into my metal garage building (one big room) which is 24' x 35'.. it is 870square feet, but it is 14' high instead of the normal 9 or 10 feet tall. How does this affect the measurement in square feet then?
Thanks if you can help me.. I am really enjoying your videos..
Hi, great video! Can you tell me how big outside unit should I buy if my basement is about 1200 sq/f ? Also, I'm not sure should I buy cassette unit or just a regular one like you have on the wall.
Not sure
The main disadvantage I've seen with cassettes is if installed in a hard lid you need attic access or a near by access panel for servicing.
Yup gotta have an access panel for servicing the equipment
That's right Joe
@@TaddyDigest have a video or familiar with a video with options on this? I won't have an attic, just a ceiling/roof that will be about 16" thick
I know it'd be a pain but couldn't you just drop the unit to service it? What kind of maintenance are we talking? I live in a bungalow style house, and I really don't want to do the full handler style, the cassette is a much better fit for me. Thanks for your help
@@psykho15 I haven't seen a cassette that the line set will allow it to drop down. I could see it being possible to be able to run it up and down on all thread and have the wiring and condensate long enough. But refrigerant ports would need to come out the top of the unit.
Cassettes will also fit in between 2 foot on center joist. Cassettes also use a radial fan which needs no cleaning as compared to a long squirrel cage and is much quieter. We always use a double flare like you would use on your brakes especially when using the preinsulated line sets as they are only half the thickness of Type L tubing. The 120 units only go to 12k but if we are in a gas home with no other 240 appliances we will offer the 120 to keep the cost of the generator down. Once you step up to a 240 inverter generator you double the price and if all you need is 1 small mini split it is worth staying with 120 volt. Good video thanks.
Great Info You should have a CZcams Channel 👍 😀
@@TaddyDigest Thats for you young guys. Im trying to slowly slip into retirement but they keep calling me lol
lol 😆 🤣 alright deal
Can you get units without condensate pumps?
If i purchased a Pioneer unit with a wall mount air handler can i swap it for a cassette style?
do you install the 48k 5ch on a wall bracket or a stand? I've noticed in the literature it says any unit over 132lbs. should not be installed on a bracket. Thanks for your help, I just started to install samsung and still have to get used to the different install procedures...also the communicating wire do you run it with the lineset and power and wrapped like other types of ductless systems or do you have to run it awayfrom any and all power sources? I appreciate it.
I usually install it on a concrete pad or a plastic pad
I also run the communication table separate from the other power cable
Would you recommend an air vent for the ceiling cassette even if you're achieving gravity fall?
I would recommend an air vent because it just makes it much smoother however you do not have to necessarily have the air vent as long as you have plenty of fall
Great video! Do you know if the ceiling mount cassettes can be installed in a slanted ceiling?
thanks and no on the slant they have a drain Pan so water would poor out
they have to be level
Awesome content! Virginia here. So sizing the units. I do load calculations for each space add them together for the total btu for the condenser. The individual wall or cassette are sizes per space? Can you do up to 8 rooms? Thank You
Yes you could do 8 rooms you would have to use a 5 ton DVM Eco With that many indoor heads
@@TaddyDigest Thank You Sir! 5 tons is a lot of a/c for the square footage involved. The living space is at the bottom of the house situated on the north east side. However I’m assuming the individual units will handle the “ conditioning” even with a bigger condensing unit! I’m thinking the heat pump will be more than sufficient. The homeowner doesn’t want to supplement a secondary heat source. Located in Central Virginia.
We have 2 ceiling cassettes in an apartment above our garage. We have access to the attic for maintenance. Can we run the drain lines straight into the 1 1/2 inch kitchen pvc vent pipe coming up into the attic? We will use a 4 way 1 1/2 pvc fitting and run 1 1/2 pvc to each cassette with a short 3/4 pipe into the 1 1/2 pvc pipe. Not planning on using a trap unless we have to.
Where is the condensate pump located on a ceiling cassette? Thanks always for the fabulous content!
It's located inside the equipment above the drain pan
Hello . I really appreciate the information you provided on the cassette air handler . I have a 3 foot high attic is that proper ventilation or do you think it would cause issues ? Also they sell cassette mini splits with built in condensation pumps is that correct ?
yes
Is the main board bad , to reset the remote control setting. Thanks
First time watching your video appreciate you sharing your knowledge! I have a question I have a 45' Storage container I'm using as a grow op I had spray foamed about 1.5 " average overall Im in Oklahoma, was looking at a 36k BTU mini split not sure if I should go (2) 18k handlers or (1) 36k in your opinion is that sufficient or not? Thanks in advance!
Depends on where you put those air handlers
And how your grow operation is set up
The more air handlers the more air
But the best place to put an air handler is on the narrow side so that it has the best chance of having the most air throw
@@TaddyDigest Ok that makes since, glad you mentioned that. I was going to install it in the middle on one of the long sides. I did build a partition wall to separate the grow room & a clean room that’s 5 foot from container entrance, in your opinion should I install (2) 18k handlers one on the short wall at far end with the other on that partition wall with them facing towards each other. I’m just wondering if I can get away with (1) 36k btu handler vs (2) 18k btu handlers in order to save a little money. Thanks for your input & sharing your knowledge!
Hi I’m building a shop in Minnesota 1800 square feet 16 foot sidewalls and two 14 foot overhead doors .I will have floor heat from natural gas boiler . I also want a mini split for air and heat when the floor heat isn’t either quick enough or when it’s not going to stay cold . It’s mostly going to be one big room with a bathroom and a room for utilities. Planning on a wall mount single unit . Would a 36000 btu unit work ? Or since it’s not the only source of heat should I go smaller? I plan on doing the install myself with a mr. cool or another DIY unit . Any advice is appreciated. Great video content 👍 keep it up !
3 ton would be perfect so yes go with that one for sure Thank you for watching please hit the like button
Hey Tad, great video and very informative, My brother and I recently bout a 70 year old house with no HVAC system in Anderson S.C. and the roof is too low for a duct work.
We are getting estimates from about 8-10 different companies to install ceiling cassettes in each room, and I want to ask for some advice.
1 - Do you happen to know any HVAC companies in my area that you would recommend?
2 - and what Brands of systems would you recommend the most, I recently found the Samsung ones and like those, but what are some of it's best competitors?
3 - It's humid here, do you happen to know what cassette brands also dehumidify? or is it common for most of them to do it?
4 - And Mold issues with these I should know about?
on your question #3, some units have a dehumidify setting, Here in Yucatan Mexico the humidity is extreme, I would be careful with sizing, going too big does not dehumidify well. I am using AUX brand in Mexico, but they don't have the same quality product line in the USA, I do use the dehumidify setting on mine.
I have LG ceiling units. One of them keeps shutting down with a condensation pump fault. Do you have any content or information for repair or replacement for those built in pumps? Or can I install an external pump and bypass the built in pump? Thanks!
I have a video of a Built-in Pump that I worked on on a Samsung Check out my playlist HVAC tips for technicians
For a Single Family home 2 levels in florida.. would you recommend a VRF with 4way cassette fpr each rooms? or a ducted system is better
The more units you have the more expensive it is.
I would do the Ducted over the 4 way especially if there's not a lot of room around the cassette
I like more open areas for the cassettes
@@TaddyDigest Is Mitsubishi Hybrid VRF same as the one on this video?
Same setup basically but this unit was a Samsung VRF
Building code official and design engineer here..I don't like the concept of having several different ahu units in the ceiling especially with condensate overflow problems which occur with all units. I would use a unit that was wall mounted and then use many ducts to go to different rooms
Would a ceiling mounted minisplit with attic above be a better option that a ducted system installed in the attic in terms of efficiency? Concerned about the known issues of installing a ducted system in an attic and looking for alternatives. Thank you.
yes absolutely
I want to install a wall mount mini split in my garage. I’m trying to figure out what size I need for my two car garage that is connected to my house. Is there a chart to size mini splits being no duct work. Thank you for the video.
Hey Jason I have a mini split sizing guide
Click the join button beside my video and then send me an email and I will send it to you
Hi. Which has a better cooling capacity?
What brand of rope hook do you use? I'm looking for some to hand a dehumidifier from.
check out the hung rite brackets they are awesome for hanging equipment
A ducted mini-split plenum would have been a better choice for that shop.
I have 2 x 12” joists on 24” centers. It is decked for a loft on top and will be dry walled below. It is a new construction and I am considering the Daikin ceiling cassette. Is that practical for installation and maintenance?
I'm not sure I would really need to see it
We have a rental with 4 ceiling cassettes installed 2020. One of the handlers is displaying what appears to be mold along the 4 outside edges of the cassette. Filter is clean. What do you think can be the cause? What to do to fix?
Make sure that in between the ceiling and the sides of the cassette are insulated and sealed.
Check the humidity in the house. Is it high? may need a dehumidifier if it's above 65% percent or higher
That may be a good place to start
Hi Taddy, are there any ceiling cassettes that would fit the 14X14 inch openings on RVs? Thanks for the most informative video on mini splits I've seen yet. Tari from Houston TX.
I think the lowest dimensions are 24 x 24 for the Mini 4 way cassettes I will check into it for you 😉
I just saw that mitsubishi makes a cassette 14.4 inches wide and like 47 inches long. Made for 16" center joists.
Here is my problem. I am having our covered patio enclosed as a sunroom in a few months (the company is extremely backlogged). It will have 3 sections of glass (transom, windows, kick glass) covering all the way from top to bottom with no room (maybe 4 inches to ceiling) so there is no room to mount the standard mini split anywhere. The sunroom will also be enclosed on both sides. So the only places left to install one would be against the brick on the back of the house. Then the lineset and drainage would have to go up into the attic and over and out to the unit. Since drainage would go up I would need the condensate pump. The area where these lines would have to go is where the roof slants down and there is no room for anyone to work in easily. I can't seem to find a dealer who wants to tackle it. The ceiling cassette option has a similar problem. There are lots of rafters all over and the contractor says a sizeable square would have to be cut out for the unit, which would compromise the roof structure and they wouldn't want that responsibility. Im almost wishing I would have went with a PTAC unit and just live with the noise and the view it would block. Can you think of any other solutions? Thanks.

I have an 1100 sq ft home with no heat or ac it’s a cabin and wanting to install a split unit into it so I can live in it full time. It’s a slab on home with an attic. It’s in Minnesota by a lake so it gets -30 degrees here and summer 110 with 80% humidity. I’m not sure which one to do. I’m very low budget being single and doing this myself. The walls are already up and I’m not sure how to do or which one to do.
Hello,I av split ac of 2hp inverter to be precise, the supply pipe wasn't working but the return is cooling, what may have been the cause of this please kindly help
What did you do to connect the condensate line to the pvc for the wall unit. Any code on this? Looks like you inserted the insulated plastic condensate line into pvc? I am installing wall unit and running condensate line down inside wall exiting at 6in above ground at exterior.
Yes I just inserted the line into the PVC
You can use 5/8 tubing and it will fit inside as well
Hello ! Tad, I'm installing mini split with the wall air handler when I run the lineset can I run it under the eaves of the house to the inverter?
yes
how long should it take to install a ceiling vs wall mount mini split in a new construction room (12x30 room)?
Ceiling Cassettes take more time to install then wall mounts
Can a gravity line for condensation by applied so it goes down the inside length of the wall into a crawl space?
yes you can gravity
Could these be mounted in the floor? Like in the floor of a room? And the lines run in the basement?
No but you can use one of the console units
Check out my video I did on what types of Mini splits there are
If under my playlist hvac tips for home owners
The console units are nice
What maximum distance should I consider for the condensation lines before it affects the performance of the cassette mini sit units?
the drain pipe?
Is a mini split cheaper comparison to a traditional hvac in terms of electricity bills?
On the ceiling cassettes you have to look at your roof rafter spacing to make sure the cassette will fit between rafters.
My attic has rafter spacing of 22 inches which the larger btu units will not fit into.
I turned a shed into a small house. The Loft where the bedroom is gets no heating or cooling from the mini-split. The flooring and sailing to The Loft is Plywood And 1 by 6 boards. Any recommendations?

I am using the cassette in my dorm rooms in Merida Mexico. I like them, I like the condensate pump, which gives me a lot of flexibility. I installed a variety of sizes from 1.5 ton to 5 ton. My outreach teams are very happy with the comfort of the dorms. Here I am using AUX Brand, but they are different than what is available in the USA, I don't think I would buy AUX USA models, and I don't think they even sell the cassettes in the US, it appears that they are making lesser grade Wall Units for cheap sell in the US. I like Taddy's comments on not self-installing, a lot of people do that here, they don't vac down the lines, and on hot days, which is the norm here, it will not cool properly, There are many people that I have discharged, vaced down and recharged and they are surprised of the difference, and their electric bill also drops. Here in Mexcio we pay over .45 cent per KWH.
One more thing I like about my AUX units is it has fresh air intake mounts, which i utilize.
Well thank you for this knowledge my friend
Any idea about a great installer in DFW, Texas?
I wonder if anyone has attempted refitting a condenser that originally came with a wall mounted air handler with a ceiling cassette. I would think it to be a straight swap but have not yet seen any videos on the subject.
