    As a mini split owner myself, I can honestly tell you after servicing two head units in my house that were really dirty from a few years of use, you should never put one up really high, especially above stairs, where it would be hard for the technician to service it or clean it out.

      Inconvenient, yes but having service a lot of AC units that are in crawl spaces or through small hatches buried in a wall in rafters with no floor, it's fine I have a adjustable ladder that's designed for stairs. Keeping it so high up keeps it out of your visual line and that's worth it. And in Matt's case it's a party unit, so it won't get used much

    My house had a Frankenstein setup of separate upstairs and downstairs forced air HVACs along with the chaotic attic duct work, it was all a mess. Pulled it all out and replaced it all with 20 mini-splits across 5 outdoor condensers. The old system was wildly uneven, problem prone, and struggled to keep up in weather extremes. The new system is wondrous, complete and absolute control of every room, I have it setup so that I can have an entire condenser die not be that concerned, and most importantly capacity, compared to the old system, isn't even in the same league. It's all networked and completely controllable through automations, and despite being about 500% more capacity, electric usage dropped by 25-30%.
    Night and day difference, it wasn't cheap to do this by any stretch of the imagination, but I don't regret doing it for a second.

      Finally, encouraging words! I'm doing the same for the same reasons in a new construction house, but only a dozen heads, two outdoor units. In the framing stage. Can you offer any tips on how to do this successfully, and avoid the pitfalls? I think I have it figured out, but I could still be blind to some things. What brand did you pick? I'm planning on Mitsubishi ceiling cassettes on the recommendation of my AC guy, and Matt himself, but there's still time to change it if I have to. I have some more questions regarding known pitfalls of mini-splits in another comment on this video, if you can check it out. Talking in person would also be amazing, but no idea how to get in touch on here.

    I am a broken record but maintenance, maintenance, maintenance. If you don't clean these properly they will really not perform and get nasty. I don't know how many people realize just how often they require attention. I would not go a full year forgetting about any indoor head unit etc. Much of the cleaners are intended to be used for routine maintenance. Not for something that had excessive buildup etc. I clean ours once a season so about 3 times a year. There are two in the house and one in the shop. Obviously the one in the shop is trickier.

    Matt. I have a solar powered mini split that is a DC/AC combo. So during the day. Runs directly from the solar panels. And at night runs off the solar inverter which is using lithium ion phosphate batteries. So my cabin runs completely from solar with battery backup with no external power source. Everything Runs from solar… the well, clothes washer/ dryer, lights, internet, AC etc. 100% green energy!

    It is true that mini-split or air-to-air systems can provide heating. However, as the temperature drops, the efficiency of the outdoor unit decreases because it needs to defrost more frequently. During the defrost cycle, no heat is delivered, and in my experience, this can take up to 15 minutes per hour in very low temperatures.
    Additionally, it is crucial to choose a unit that is most efficient within the typical temperature range of your outdoor environment. Different manufacturers optimize their systems for different temperature ranges. Efficiency is measured in COP (Coefficient of Performance) or SCOP (Seasonal Coefficient of Performance), which indicates how much heat the unit can produce per kWh of electricity. Ideally, you should aim for a heating ratio of at least 4.

    I've been in HVAC residential service for 28 years. Mini splits if done right can work great, but once they experience some type of failure it can be difficult to locate repair parts since most of the components are proprietary and there are no universal parts. Homeowners should be aware that even though you may have a unit that is under warranty, it may take a couple of weeks for parts to arrive

      Mini-splits by definition are not intended to heat and cool multiple spaces (with a few specific exceptions). That’s how they got the name mini-splits! Serving multiple rooms with one air handler is just a standard ducted heat pump HVAC system.

    My climate gets down to -40 degrees F in northern MN. Air heat pumps don't work the best, but ground loop heat pumps still work great. Minisplits are popular because we don't need a ton of primary cooling, but when it gets down to -40 a little extra heat output or a secondary heat source using a different energy source than the main heat source can be a life saving requirement.

    I'm in Japan and they are everywhere here. I have 4 in my house mostly as aux heat since I have 4 kero heaters, a heated floor and two wood stoves. I love that you can heat just the areas that you want, no central heat here. They are very reliable, one of mine that came with the house is 32 years old and runs like a champ. They are very frugal on power unless you are trying to heat when it is quite cold out. Another advantage of them is they run on a remote control so no need to go to the thermostat to change the temp. The have timers so you can have it come on in the morning before you get up or turn off an hour after you go to bed.

    I built a new home 3 years ago in Chicago. I added mini-splits as supplemental Heat/AC for the bedrooms. I love it!!! My wife likes it cold, I don't. So at night, I go in my bedroom and turn on my mini-split and life is perfect. I also don't have to heat or cool the entire house overnight. The only down side is when it gets to 5 below zero, they no longer produce heat. Maybe they will improve that in the future.

    As Matt says here, he uses his mini splits in ways he didn't predict. Sometimes the mini split is his MAIN source of heating/cooling, and sometimes it's not used. So my suggestion is to design a central air system (like Matt did), and then add mini splits later as necessary when you find uses for them. For example, when your duct plans fail and leave one bedroom cold, add a mini split to it, rather than starting with a mini split in every room.

    Let's talk about non-myths:
    1) More units is more maintenance
    2) Temperature control on most systems sucks, with very wide thermostat bands
    3) On some systems, like Mitsubishi, the fans run constantly, even when no heating or cooling is called for.
    Do folks have tips on solving these?
    For 3), on Mitsubishi units you have to cut a physical jumper to disable the continuous fan. Pretty nuts, but at least it's possible. Ostensibly it works that way to circulate air, so the internal temperature sensor can sense a better average temperature. But it seems pretty crazy with wall mounted thermostats. And in general... Ends up burning more power than conventional systems.
    I also hope the outdoor unit can get to a low enough speed to feed an indoor unit running on low speed with low heating/cooling demand. And what if it can't?
    I'm building a SIP house, very well air sealed, so I expect my heating and cooling demands to be generally low.

I had to buy a new step ladder to be able to clean the filter, which I wish was designed better. I can either shop vac the filter, or wash it. But I do wish they made a "kit" to improve the filter aspect, especially since my shop gets a lot of dust, welding smoke, etc.

    Room size air purifiers are great for a bedroom, but once you add up the cost of the machines, the electricity and especially the filters it is more economical to have a whole home air filtration solution installed in the hvac and then a room sized purifier in the bedroom of anybody with issues such as asthma for that additional boost. I personally like the reme halo led system coupled with an electronic air cleaner and a filter box large enough to provide high merv without too much pressure drop for the health of the system.

    I think whole house filtration is the one thing that's making me rethink my options for our eventual retirement home. Mini-splits are great for multizone heating and cooling, but I don't want a bunch of filter boxes littered around the house. I may still use some form of mini-split, preferably with a ground-source heat pump but I still want whole house filtration. If for no other reason than being able to use bigger, cheaper, and easier to maintain air filters.

I think I'd rather get a single V- or W-box in the mechanical room and just route a bunch of hoses through the second floor trusses. I probably would do a box like that for the ERV though.

    Myth #6, mini splits are more efficient than central ducted systems. This was true several years ago when mini spits were marketing seer 30+ and conventional systems were seer 14-16. Now, the much more realistic seer2 knocked the top tier seer 38 mini splits to seer2 27. Only the very small 3/4 or 1/2 ton get that high, but most 1 ton and above are only seer2 16-20. Meanwhile the central systems have improved vastly and reaching seer2 20 and up to 23. There's no longer a good reason to use mini splits.

    Ducted mini-splits, that's it! Hide the unit in a conditioned attic, crawl space or utility closet. Then you can add a fresh air ERV/HRV system such as Zehnder (or others) and I think that would be the ideal combination for fresh filtered and dehumidified air plus the most efficient heating and cooling. Thanks, Matt & Steve! PS: Please do a presentation on ducted mini-splits. Also, I have no personal experience with mini-splits, but it seems since they have a built-in fan, they'd be noisier when operating than a ducted system with an air-handler located far from the vents in the rooms. Maybe someone could comment on mini-split noise. Thanks again.

      I installed a Pioneer ducted mini-split to condition a couple of rooms in my basement. I really want to like the thing, but it has one huge flaw: the temperature control is awful. Suppose it's 71 degrees in the room and you want it a little warmer, so you set the temperature (wall controller or remote, they both work the same) to 72 degrees. Nothing happens. So you set it to 73 degrees... again, nothing happens. Set it to 74 degrees and the unit comes on and starts heating. And continues, and continues... I usually get fed up and turn it off when the temp in the room hits about 80. From research on forums, I understand that that behavior is pretty typical.

      True to a point. But the COP when the unit is operating in that cold of an environment is 1.2-1.6. Barely more efficient than just electric resistance. If your area gets that cold it would be worth it to invest in a wood boiler and radiant floors. Then just use the heat pump for chilly days.

      I have two ductless mini-splits rated down to -22F. Their heat output drops as it gets colder, though. I sized them to provide enough heat at the coldest outdoor temps I see in my area. A basic Manual J calc and a glance at the units' spec sheets made it an easy decision. I have a 12k and a 24kBtu/hr unit, so 36kBtu/hr. At 25F I expect 31 kBtu/hr from them.
      The variable compressor speed and variable fan speed technology is great, too. I was able to oversize my units (to meet my coldest day and hottest day needs) without causing short-cycling on normal days.

Do note that if you have natural gas available, it's likely cheaper to heat with below somewhere around freezing +/-5°c depending on utility rates and model.

    Hmm currently building a barndo type house that I am planning on using mini splits for but the one thing I had not thought of was the air filter, don't really care what it looks like for the space and would provide plenty of heat and AC but I'm on a dirt road with lots of dust, so you may have actually talked me out of them for my application... Food for thought. Thanks for the thought.

      Yeah, you should have a dedicated ERV system with mini-splits in a new build or you’re not going to have good indoor air quality. An older house may or may not be leaky enough to have adequate fresh air, but it’s not going to be filtered and pressure balanced regardless.

    #1 Super expensive period. #2 I have a Mitsubishi i have had for 14 years. Dead now but did love it. I always changed the filters but was shocked in year four of only using for air conditioning. The blower wheel was not putting any air out or very little . I took it apart (nightmare) and was astonished at how much mold and gunk was on the blower, made me ill looking at it..I am replacing it because it worked great, but now know to clean the blower wheel more often.

    my apartment manager says the new unit they installed in all the old apartment buildings is a "mini-spit" but its installed in place of the old central air unit.
    I think they meant central-air heatpump. either way the unit is horribly underpowered especially now that its colder. but even just barely below freezing at night and the heat drops below the setpoint by a least 2f, or 1C. the HVAC guys say the unit is working properly and just totally ignore that their install isn't actually working as a resident would want it to.

    Biggest issue with mini splits is, they are absolutely useless in a basement in most of this great country. Not enough sensible heat load, and the smallest indoor unit is 7kBtu, so it doesn’t take out enough humidity and the basement stays damp and musty. (the “variable” models are bs. it’s only the condenser that is somewhat variable, in reality it only adjusts its btu output depending on how many indoor units are tied to it and currently demanding refrigerant, but each indoor unit always gets full flow. Only Mitsubishi’s top of the line model can control the refrigerant flow volume to each indoor unit). I have 4 , 5 ton condensers powering 5 indoor units each. 5, 12kBtu units, and 15, 7kBtu units. The ones on the three regular floors work fine, but still severely oversized for most of the rooms they’re in. The basement units make it nice and chilly, but leave it damp.

    Myth Busters Matt, Steven and Brian 👍👍👍... My buddy lives in a very basic 2 X 4 uninsulated 1950's house in Southern California. He has a 4 ton HVAC system. A few years ago we installed 2 mini splits in that house, one in the master bedroom and one in the living room to ad either additional AC or primary AC depending on the time of year. Here is the BIG BENEFIT, when his 4 ton HVAC system went out, those mini splits managed to keep the interior under 80° when it was 110° outside. Multiple mini splits offer unique value in redundancy... Myths busted... Great video, thanks for sharing, blessings and Merry Christmas wishes to all..... 🙂👍

      That is one thing I dont get. They should build an all in one unit. I know some people have built out systems that use the same ducting but it can sometimes be a little difficult to get right. If they just built an all in one system or a system that was designed to work together that would make way more sense.

    • @MichaelJ674
      @MichaelJ674 3 ชั่วโมงที่ผ่านมา

      Unfortunately, you usually have to pay for additional consulting/engineering to get an all-in-one system to work properly without having unintended consequences. Most installers don’t even use a basic Manual J calculation when sizing a system; they just use rule of thumb. So to expect them to properly design and install a combined heating, ventilation, and air conditioning (and humidity control) system is asking a lot. Where I live, there are at least two HVAC contractors that have licensed engineers on staff, but they typically work only on commercial projects and really large residential projects.

      You will not be happy with a mini-split system in GA with no dedicated ERV system and dehumidification. In fact, you will almost certainly have mold growing in your walls without ducted ERV and dehumidification unless your house is really leaky in terms of air infiltration. Even then, you’ll probably grow mold behind vinyl wallpaper, pictures hanging flat on the wall, and anywhere else the walls can’t “breathe.” Of course if your house is that leaky, your electric bill will be astronomical.

      I am a licensed HVAC contractor in florida. Most of the standard GREE brand mini splits that i install will heat effectively down to -13F. Not that we see those temps in florida. But they are capable of it. They will also cool when outdoor temps are as low as -4F. I have a client with a couple of server rooms that need to be kept cool year round..the servers create lots of heat, meaning, even in winter when its cold outside, the server rooms still need AC cooling. Most traditional split system air conditioners will not continue cooling when the outdoor temps drop too low...not without a low ambient cooling kit put on it...which is essentially a fan cycling relay/timer/pressure tranducer...which turns the outdoor fan motor off, strategically, to keep the head pressure from dropping too low to allow the refrigeration cycle to do its thing.
      also of note, GREE's Ultra series mini splits can heat down to -31F outdoor ambient. Amazing.

    • @MichaelJ674
      @MichaelJ674 2 ชั่วโมงที่ผ่านมา

      What are you doing for fresh air? A tight, code-compliant building envelope needs some sort of ventilation system to provide fresh air, manage CO2 levels, and filter the incoming air (bonus points if you incorporate an HRV or ERV). It’s probably not hot enough or humid enough to need dehumidification during the summer in northern Idaho. I’m guessing you just open a window at night like we do over here in Oregon.

    I'm building my 4300sqft house with ceiling cassettes in every room/area. I didn't want to deal with people in different rooms being unhappy with someone else's thermostat setting. Even closing a door vs having it open greatly affects the cfm coming through a duct. Balancing registers every season sucks, plus never turns out that well. A single head in a room has no such issues. It's not that expensive. 45k for like 12 heads, two narrow outdoor units. No big deal. And saving the labor and planning headaches of running big ducts where they don't fit is nice.

    • @MichaelJ674
      @MichaelJ674 2 ชั่วโมงที่ผ่านมา

      What you’re screwing up is not providing a dedicated, whole-house energy recovery ventilation (ERV) system for fresh, filtered air (unless you just forget to mention it). You’ll probably need dehumidification during cooling season as well depending on where you live. Presumably your existing ducted system could be modified to provide these functions. The existing ducts are way oversized, but that’s much better than being undersized and dampers could be used to balance the system. Transfer grilles and ducts in the ceilings between bedrooms and hallways can eliminate the imbalance created by opening and closing the doors.

    • @steelddd
      @steelddd ชั่วโมงที่ผ่านมา

      ​@@MichaelJ674 Yes, I'm using a Zehnder ERV. It's pretty much a requirement anyway with tight SIP construction. It's new construction, so no ducts planned. I'm in Los Angeles, so humidity is not really an issue.
      Transfer grilles were a possibility, but they also transfer noise. IMO central units are not really possible to balance for many reasons,. though changing seasons, etc. And even if you could, every person's temperature requirement is different. Zoning with a ton of dampers was also floated, but I was told those systems don't work well, either. But I appreciate all input.

    This video is right is right on, mini splits are great for heating and cooling. However they are a maintenance nightmare so if you like mold blown around your house and $400 to $600 maintenance bills per year buy a mini splits, you'll love them! My experience was that any energy savings you have are blown on astronomical annual maintenance bills. If you have mini splits you will have poor indoor air quality mold mildew dust.

    IQ-AIR!!! Dude If your going to do stand-alone filtration there’s nothing that beats “Swiss Made” I can’t believe you don’t know about IQ-Air, not crazy expensive and Hospitals use them. They can remove the smallest particles known to man. I have sleep apnea and I wear a blood O2 monitor to bed and my blood oxygen levels are 4-5 points higher when these are on. I’ve had air filters my whole life and nothing compares to these. Did you guys know we are all breathing microplastics? I just found that out. There’s so many things in our environment that are trying to kill us and we find out about more everyday. That’s why I bought the filter that can filter down to the smallest possible molecule. Or in the filter world they call that a micron and these go lower than 1 micron. That way only O2 can fit through the holes. It’s technically called air scrubbing or air washing when you get that low on the scale. Also IqAir last 2-4 years because there’s so much surface on thier filters. If you pulled one apart and laid all the filter area flat it’d be the size of a car versus the next best, Dyson which had way small filter contact surface area like 4x4 feet. Can’t believe that much can be fold into those tiny machines

    I've owned a large HVAC company that does thousands of installs per year. Ductless are great for bonus rooms or garages, but traditional systems are better 99% of the time. Main reason are that ductless are a pain to service and in my experience have a much higher chance of failure (the pumps they use are often loud and annoying). Additionally, the techs cannot have the parts on them to easily fix while there like they can for regular split systems. In most cases splits systems are less money too. These ducted "mini-split" systems or the ones with multiple interior heads are very expensive, and do not work the way people think. You cannot heat and cool each room/zone simultaneously without upgrading to even more advanced systems that are extremely expensive. Simply not practical.
    PS -- If you are needed ductless due to some reason that a regular split will not work, Id recommend you stick with main brands like Daikon and Mitsubishi that offer legit warranties, and go to a ceiling cassette that looks much cleaner and has the pump already built in.

    One thing that isn’t a myth is how ugly that thing is.

    Tbh yea they are hideous. But also, why not just put in a pizza box and duct a single room with it? Also makes sure everyone's happy with their own zone.
    Edit: nvm he actually did this XD

    Ducted mini split?🤨🤨... Ok at what point is it no longer a mini split and just a small central heating and air unit...

      the ducted units have lower BTUs than most stand alone ducted systems, also this allows zoning, and you can add filtration to the incoming air side

      You can run several ducted heads off one outdoor unit, so you can still get better zoning. You have the option to mix and match tonnages and form factors. I opted for all ceiling cassettes for simplicity and optimal zoning.

      Agree, a mini split does the heat/cold transfer directly with the air in the room that they intend to heat/cool down.
      When you add ducts and do the heat/cool down another place it’s just a normal ventilation, size doesn’t matter

    Since you didn't mention it as a Myth... From observation of several TH-cam Videos.. Mini-splits are difficult to clean. Apparently, the mini-split manufacturers do not make them easy to disassemble for cleaning and have many plastic wearing parts (that wear or are easily damaged when disassembled, eg. metal screws into plastic). Additionally, cleaning is recommended 1-2 times per year. Are these thing really designed for a 20 year lifespan?
