How has the unit performed in heating and cooling your garage in the time since you made this video?

[@patricklewis8591]

You mentioned the intracies of min-splits being a maintenance problem, but could you reference the make(s)/model(s) you found to be less of a problem??

[@miketonon7946]

So if I were building a new 1300 square foot colonial in Connecticut, could I completely heat and cool it with a newer mini split system or would I still need something else to heat it? I was thinking of doing gas hot water heat and radiant floors. But I wouldn’t have central air conditioning and I’m not sure, but it seems like mini splits are probably more efficient than gas hot water. What do you think?

[@tjinytjiny6615]

I had a Mini Split System installed in my home 2 years ago. I had 4 units installed, 3 9k/1 18K Mitsubishi MLZ Ceiling cassettes cause I didn't want to see wall units in every room, or the holes in the wall. I do have a wall unit that I purchased used that cools off my entire basement. After 3 yrs it was low on freon and I had to top it off, otherwise its never given me any issue. I'm having a 4th 9K installed in a couple of days for my kitchen. I installed it over a conventional system because I saw no purpose in air conditioning bedrooms that were unoccupied all day, most days, or cooling an empty living/dining room all night. When there's no one home, the CAC is off I've had zero increase in my electric bill. I LOVE my system and how it works. When its bed time I turn off the Living room unit and turn on the bedroom unit. At 1st I'd turn it on 5 mins before I went to bed to cool off the room. I stopped doing that because cold air comes out with 20-30 seconds of turning on and cools the room in 3-5 mins. the units are whisper quiet. Even though my system provides heat, I prefer to use my gas heated cast iron baseboards in the winter. So far I am 100% satisfied with my mini split system.

[@brookschapin7879]

[@al3645]

So worth it. Installed 18,000 btu unit and two head units, one for master bedroom and one for Livingroom below, and is fabulous with heating in the teens and single digits, and cooling in 110 degree weather. Installed in addition because didn’t want bulkhead to cover ducting. No regrets. Easy on the electric bill as well. Brand is Perfectaire btw. I highly recommend.

[@89Mirageman]

Did you do the install yourself and do you remember what you paid for everything?

[@jimvano]

The single most important reason to install a mini-split is that they are way more efficient than a traditional ac system given the variable flow refrigerant nature of the minisplit.

[@BenjaminSahlstrom]

For sure. The way they are able to ramp up and down is seriously impressive.

[@jimvano]

And after installing 3 multisplit systems in our ranch buildings, I would say two other negatives are that they seem less efficient at humidity removal and it is more difficult/more costly to get cooling or heating into small spaces like bathrooms, laundry rooms, or master closet. I had to install inline duct fans to move conditioned air into these small rooms.

[@Sightthrough]

@@jimvano Actually they are very efficient at humidity removal. This is one thing I hope Ben covers in the next video. It is very difficult to size any cooling system without a proper heating and cooling load calculation. If you put a mini-split in a very small space or over size it for a given space the mini-split will satisfy the call for cool way too fast and leave the humidity in the space. This is issue is not a fault of the mini-split.

[@BenjaminSahlstrom]

Great thoughts. Optimally you want your AC system (mini split or traditional) to run in somewhat "long" cycles so that the unit can extract humidity and avoid short cycling. This is why, in my opinion, a slightly undersized unit is better than a slightly oversized one. I believe my main AC system will run for close to 45 minutes per cycle giving it plenty of time to collect and drain away the condensation.

[@MyGoogleYoutube]

@@BenjaminSahlstrom The best way to run a mini split is to never shut them off. When you look at the specs of a mini split you notice a btu range. A 18000 btu system might have a range of 4000-19000 btu range. Which in my guess is it's better to not undersizen it. You will lose the advantage of a variable speed compressor if you undersized. It will never slow the compressor.

[@eltunene]

Dear Benjamin, I live in northern Mexico, and winters are surely cold here. I installed a cooling-heating mini-split back in 2017, and it has worked nicely, both for heating and cooling. Only once it displayed an error message, after a whole year of use. The error was E8, and in desperation, I thought I had made a poor investment, however, an idea hit me an I simply cleaned the mesh filters at the air input in the indoor unit. Worked like magic! It worked nicely again. What I do ever since is to clean them with a dry brush every year, and no problem whatsoever. My opinion is minisplits are great, and highly efficient in both functions. I even took my natural gas bill down by 90 per cent! Another bonus is the water coming out from the outside unit in summer and spring I use it for watering my trees and garden, thus lowering my water bill as well. Thanks for your very interesting and useful video!! I almost forgot, I installed some solar panels on my roof, and my light bill is also very small, in spite of having two minisplits now, plus two electric water boilers.

[@sjsu2]

Good video. We renovated an 1880's farmhouse on the coast of Maine, and our 5000 BTU Daiken unit heats the house easily most days (2 floors, 1072 sq ft total) for the past 2 years. It was our sole source of heat until 6 weeks ago, when we had a used propane fireplace with wall vent installed as a back up/supplement. We like a cooler temp (low 60's) and because we're pretty well air sealed, we manage pretty well. Only on the coldest and most windy of days do we light the propane. Also, I believe Daikens are made in Texas now.

[@Elisummit845]

I have been in the HVAC industry for about 15 years. We still have units we installed when I started and are still running great. Maybe you should switch company you are using. We mostly use Fujitsu and if you know what you're doing it's very easy to service. Mitsubishi is also great but more expensive. Parts on both of them we usually can get within a few days. Some parts can take a week. If a unit is installed right and maintained, it will run great for a long time.

[@BenjaminSahlstrom]

Agreed. We also install Fujitsu and have had pretty good luck with them. We have some units that are older and still lasting well for sure. Just seems like they don't do quite as well as a "traditional" system.

[@Elisummit845]

@@BEANS-O-MATICtransmissions that's a great question. We have to understand that a refrigerant cycle, with the refrigerant that we use (I would guess it's the same with all refrigerants) we can not have moisture in the cycle. The more moisture in the cycle the sooner the system will go bad, for different reasons. We want to bring the microns down as low as possible so the risks of the system being effected by moisture is almost 0. Every manufacturer will tell you different levels of microns and decay test level but every system has to be vacuumed.

[@davidebacchi9030]

Another pro point: on minisplit you usually have more independent system (one unit usually feeds from one to three inner "splits" so on a house you have usually at least two units) this means that if a single unit fails the home isn't totally out of air conditioning, on a central system if something fails, you have to hope hvac tech comes quite soon. As a note: my grandma has a 2002 mitsubishi twin-split and today it still in great shape. A downside is that you have to pull a condensate pipe to every inside split to drain the condensate properly.

[@ebuzek3648]

If you have a refrigerant leak, then all units are down.

[@kaylonpetty12]

Or compressor goes out or fan on outside unit or outside contactor or capacitors. There are quite a few things outside I would bet that can shut the whole system down.

[@jakesearcy8049]

I learned about minis in Iraq and Afghanistan. We used them more than anything else. Hot extremely dusty environment 120 degrees and more heat outside. All were run by large diesel generators with the voltage constantly varying and going out. They worked great. The only problems were the condensate pans clogging and leaking into the room and if someone was dumb enough to install one on a roof due to extreme heat they didn’t last long. Got home and built a cabin and I run a mini. I had issues with mold clogging the condensate pan. I use tablets to keep that under control and have learned that if I use high fan speed instead of automatic fan I don’t have that issue. Should last me a long time.

We're renovating a house built in the 1930s (no insulation and old wiring). No upstairs duct work. I'm looking at installing a multizone minisplit for the upstairs. Sounds like my plans are the way to go. Thinking the ceiling cassette style to keep with the aesthetics.

[@LeemeSeeYaJAZZhands]

A few other considerations: individual room temperature control results in significant energy savings (i.e. no need to cool your living room while you're asleep in your bedroom). The condenser (outdoor unit) is typically smaller and more quiet on a mini split system, so if you're pressed for outside space that's a plus. Also, the effectiveness of heating operation depends on the outside temperature. Colder outside temperatures are harder to extract heat from, so keep that in mind if you plan on using the system for both coming and heating and live in a cold climate. They definitely have their place.

[@TheTommyOhh]

True about the heating function. Some are now coming with heaters to help for low temps.

[@cynthiaarmstrong7972]

Can you locate the condenser unit in an attached unheated garage? Any issues with ventilation or safety? That way you wouldn’t have as dramatic a temperature difference

[@chrish7336]

Like any system the unit needs to be sized properly. These were used extensively in compounds in Afghanistan. Never had an issue staying comfortable in the Winter, and yes its gets to below Freezing steadily for 3 months out of the year. So areas that are not known for sub zero (F) temperatures should do ok with the newer heat pumps in these systems.

[@TakeDeadAim]

My house is hot water heat with baseboard copper piping. I have a split level house and don't really "live" in the lower so it's divided into two zones. We live in NE Wisconsin so see REAL winters for at least 3 months out of the year. Since we don't have forced air, a traditional A/C unit wasn't possible really. We bought a mini split with heat and it's been great. It'll heat the upper level when the temp is above freezing, so fall and spring it's the principle source of heat therefore requiring the whole home hot water system to only kick if it gets down to below 20deg at night under most cases. In the summer it keeps the upper level nice and cool. Love it. Best money I've spent in a long time! Install was very easy, just had to have an electrician come wire up a box.

[@Jswans0]

What brand did you go with?

[@Jon-hx7pe]

Yes - the heatpump mini-splits tend to heat much better and more efficiently in cold weather than traditional split heatpumps, some can maintain full capacity down to 0F or lower. Basic splits lose as soon as the outdoor temp drops below 47F, often the balance point is 32F if the unit is sized for cooling. Really great retrofit option for houses with baseboard heaters, cut the heating bill by half easily.

[@BenjaminSahlstrom]

Exactly.

[@Sidicas]

Part of the problem is that central air conditioning systems for homes are ridiculously overpriced for what you get and there has been an oligopoly on them for decades where they share the manuf. of the same unit and then just stamp a different brand name on it, sell it for the same price, and call that competition. Many Central Air conditioning manuf. feel they don't need to bother with competing against mini splits that are primarily made by foreign (non-USA) companies. But the reality is if they don't make these Central Air conditioning units more reliable for the amount of money they cost, then these American companies (Carrier, Trane, York, Rheem, etc.) will lose the entire air conditioning market. Which may be a good thing because they pretty much don't compete with each other at all and artificially set their prices high. They need to make Central AC units last 50 years or longer, or they're going to get crushed by the foreign companies. It can be done, they know how to do it. But they intentionally don't do it so they can make more money and make more sales. They intentionally make central A/C units out of inferior materials to save a penny on manuf. and also charge customers a dollar a few years down the road.

Reason some of these don't last as long is because of the copper tubes. Many don't cut them down to length (because effort) and just leave the coil somewhere. This creates an oil trap. Its best to try to avoid that and the unit will last longer.

On the other hand I installed 2 mini splits (24K and 18K) and it costed me around 3K total (I did install myself). So it is definitely cheaper than central AC unit.

[@Elisummit845]

The main issue with adding AC to heat is that your duct is not insulated. Obviously if the duct is to small or big you have to replace it. If the ducts are not insulated they will sweat when the AC runs, as your coil runs below the dew point.

I am going to install 3 mini split systems upstairs in my home, or one with 3 zones. I want them for three reasons. 1) They will serve as a back up system to my central air system. We will have a few rooms that are livable even if the main unit fails. 2) It will extend the life of the old central unit because it will run less. We keep it cooler downstairs than we like in order to cool the upstairs. With the mini split units we can run the central unit less. 3) It will make the entire house more comfortable because the upstairs and downstairs will be controlled independently. I would like to keep the old unit even though it is old because of the simplicity of it. The old unit has a condenser fan, compressor, main contactor, and capacitor.

High wall-mounted indoor units typically require servicing from a step ladder and the air filter should be checked/cleaned every 30 to 45 days otherwise the coil may freeze-up in cooling mode. A dirty filter in heating mode could cause compressor failure. If the condensate drainage system isn’t kept clear the end result could be water running down the finished indoor wall. Be sure the unit has a float switch to stop operation if the drain backs up. Blower wheels get dirty and are difficult to remove and clean. Personally, I’d stay away from wall mounted and ceiling cassettes unless easily accessible for crucial maintenance. Watch some videos on indoor unit (head) maintenance.

I have the attention span of a six week old cocker spaniel, so getting all the way through a video more than three minutes long is tough for me (blaming it on my advanced age). That said, great video. I installed a MS in our "converted two car garage master bedroom" last fall. It served us well through the mild South Texas winter and has been doing an admirable job through the searing 100+ heat of this summer. The instructions on the particular brand I bought were lacking, but with enough YT vids and a fair amount of experience in construction, I was able to figure it out. If we ever have significant problems with our central unit, I will not hesitate to replace it with one or two multizone MSs. Oh, I got my MS from Walmart. 18000 BTU for less than $1000 including the extra warranty. So, I was thrilled with the price, although I was concerned it might be a cheaply made unit, but so far, the performance has been just fine. Thanks.

I had Mitsubishi multi zone ducted minisplit unit installed in a house in the Pacific Northwest and it was trouble free for 8 years before I sold the house. It was a primary source of heat besides being an AC and it handled our mild winters with occasional days down to 15F like a champ. One service call and it was related to install issue with exposed uninsulated duct. My house was super comfortable and my bills were reduced. It was several thousand dollars more than a ducted system but I would have needed to install a gas meter and I didn’t want to go through that mess. Quiet, no dust, efficient.

[@BenjaminSahlstrom]

That's a good point for sure. One thing about the heating though is that it isn't highly reliable in my experience. This goes for all heat pumps in general as they tend to have a MUCH shorter lifespan since the compressor runs twice as much. That's why generally I recommend a separate air conditioner and gas furnace. I do love that they have the ability to heat as you mentioned though as it is a good backup option to have.

Thanks for the video. I just got my mini split hooked up last week. I ended up going with the Mr. Cool ductless DIY. I boight one that was not DIY at the start cause it was cheaper in the beginning. But when I read up on them, how a license ac person had to put it on to get the warranty, i started calling and ot qas going to run me more then the split ran me. I sent that back and got the DIY, went with a 18000 btu (a lot bigger than I need) and I love it. Had a friend help me hook it up and had it going in about 3 hours. I read most of them are about the same but the warranty with the Mr. Cool seem to be a lot better then the rest of them. The warranty to me is a vig deal. Our main AC gave us so much problems for the 1st 10 years and all the big name local shops wanted to do is band-aid it, or sell us a new unit, so that is why i been very picky when I decided to go with a ductless unit.

[@R900DZ]

Thanks for the info, one more important PRO for mini splits is they are 30% more efficient because the air doesn’t have to make its way through the ducts (losing its cooling ability) before being expelled into the space. Also, the air doesn’t have to be pushed to the place it needs to go, again saving energy. You make the cool air on the spot and that saves energy.

I would say a huge advantage is the noise being so much lower for a minisplit. At least with the one I got with the inverter drive, it is nearly silent and barely noticeable over ambient noise in a suburban area while standing right next to it. At least so far, as I haven't tested it up to full output on a hot day yet. Also you can get powered dampers that connect to a thermostat for each room, but would make it tricky to keep the larger central unit running without icing up if too many dampers are used and most of them close at some point. Some portion of the ductwork would need to always remain open. Also you wouldn't be able to make the particular room any cooler than what is available from the main controlling thermostat. You could wire both thermostats to turn the system on, but then the individual room could cause the rest of the house to be too cold by keeping it on when the other thermostat says turn off. Not as ideal as the absolute control minisplit have obviously.

Here in Finland mini split systems are installed mostly as heat pumps, cooling is just a (big) bonus for most home owners. Also most systems here are designed to work in cold conditions. -20c (-4F)is quite normal spec how cold those new systems can work, although manufactures kind of cheat here. Mini split will work at -20c but unit that is spected 5kW at 10c (50F) is probably 1kW or less at -20c. Another heat source is still needed here because in most of Finland there is more -30c(-22f) days than +30c (86F) days per year. (At least it used to be so...) Also because of popularity of hydronic (is that right word?) heating systems, air to water heatpumps are gaining more and more users.

I'm from NYC and the majority of the homes here don't have ductwork. Since 2010, I've been seeing mini splits and VRF systems being installed left and right. Lots of new commercial buildings and apartments are installing VRFs and mini splits by ditching traditional RTUs, PTACs, and hydronic heating. Never seen anyone install ductwork in an existing home for CAC. Personally, my favorite brand is LG but Mitsu, Fujitsu, and Daikin are also fantastic. No American brand manufactures mini splits since traditional ducted units are still king. All LG units are made in Korea and Mitsu, Fujitsu, Daikin VRFs are made in Japan. I would stick with the mentioned 4 brands as they do have good tech support and part availability. There are more complicated and expensive to fix if they do break so make sure you find a competent installer who has completed training from the manufacturer. Eventually, mini splits will replace traditional ducted systems and be the new "norm" for HVAC, as new energy regulations take place.

The building did not have air conditioning so if you wanted AC it was done via mini splits. And when your office is only 5.6° north latitude you do want air conditioning.

[@gdhone2371]

One of the advantages you missed is that in system that has many units it can transfer heat from a too hot area to a too cold area (like a basement) instead of transferring it outdoors and vice versa. That works well in split level homes. In most systems the remote is not a thermostat, it is a controller. The thermostat is in the air intake of the room unit. Many systems can be easily controlled from a central controller setting max and min temps allowed to be set in any zone, also scheduling. If someone wants to cool a zone to 68 degrees and sets the room controller for that, while the min is set for 72 on cooling in the main controller, the unit will only cool to 72. Another advantage is smells, dust, smoke and pathogens do not move from room to room through the HVAC. Refrigerant conducts and transfers heat much more efficiently than air with less loss. If you buy a residential unit from a manufacturer that makes commercial units parts distribution is pretty good. Service companies that work allot with the mini split system brand you buy will carry or stock parts.

I noticed you talked about the ability to cool multiple zones differently. I think it's important to note that if you're like me, the esthetic is not nearly as important as the ability to properly cool and heat rooms in my home. I live in Texas about an hour east of Houston, in a modular home. The original ac barely made 10 years, and was terrible for efficiency and effective heating and cooling. In the past seasons my family suffered due to overheating and cooling in certain parts of the house, and no ability to heat and cool the rest. Ducted systems lose effectiveness the farther you get from the unit, so my daughter got blasted being one room away from the unit, while my wife and I got nothing hardly at all, being on the other end of the house. While it is true, the bigger full central air units may last longer, they're not bulletproof, they're very expensive, and almost always require professional support when it comes to any maintenance beyond the filters. The smaller mini split units are simple, and can be installed by the diy guy in most cases. An hvac expert should be called when vacuuming the system, but that's about it. With mini split units, one doesn't have to heat or cool all the individual rooms in the home, which is much more efficient. I'm a proponent of multiple single zone units, and for one reason. With multiple single zone units, if a unit does go down, I still have the ability to heat or cool other units in my home. As far as price goes... well I try to look at the big picture. Ducted systems seem cheaper at first, but I found when looking at the bigger picture, it ends up being more cost efficient with the mini split unit, even if it doesn't live as long as the central air unit. That being said, this is a question of the home owners needs and preferences. Either solution can be useful, but for me, I choose the mini split. Oh and just like anything else, price often comes down to the owner. I just purchased a mini split system for my master bedroom and bathroom, and found it to be very affordable... much much cheaper than replacing my entire unit which require changing both the outdoor unit, and the indoor unit as well as all the lines. The bigger unit may be cheaper for others who would not have to replace both units. But the unit I purchased is cheaper than any descent hvac unit available. And no I didn't buy the cheapest unit out there. I can't afford the best units, but I've found that many times a good middle of the road unit provides great value. It's still a quality unit, and it can be affordable for those of us with limited budgets. All invested, my unit will come in at about $1200.00 completely installed and running. This comes with me doing all the install, and the electrical work. An hvac specialist will be called to pull the vacuum on the installed unit. That's much better than the $4000.00 -- $6000.00 minimum I was quoted for replacing my old system. Now keep in mind that I would have to spend significantly more if I decide to do multiple units, but even then the cost still comes up less when you consider the efficiency over several years use. Thanks for the video

[@thomasbarnardjr9657]

@Steven Strain yes sir that is correct about the voltage. I put 230-40 V unit in my master bedroom. It keeps it extremely cool with very little effort, and also has a heating strip as well. I can't say anything about Mitsubishi, as I bought an Innovair unit that is 12000 btu. I did everything myself, except vacuum testing the unit. So far we love this thing. Like I said in my previous post, this really comes down to personal preference. The hvac tech that pulled the vacuum for me is not a fan of these units, but I love them. It's important to be aware of what you're getting, how it works, and the pros and cons. Then you can more prepared to make your decision. These are becoming more and more popular here now and I believe they will become more acceptable among hvac guys, but I believe the big hvac central air and heating units will always be the mainstay... at least here in the U.S. But for me personally, I prefer the split systems.

I have a central heat pump, 2014 Goodman 4 ton unit that cools my 1,800 square feet great, even about 5-7F every hour it runs. I installed such a large unit because at 30F, the heat output is only 32,000 Btu's and at 20F, the coldest in my area each winter (Portland Oregon). it is just enough to keep my place warm, without ever hooking up the back up electric heater! These modern 21 SEER units will use about 2/3 the power of my 2014 vintage unit! SO I plan on installing a 12,000 Btu unit in my bedroom. I also plan on installing a de-superheater, to warm the water going to my water heater to about 95F. This will use 0 additional watts in the summer, and can heat 14,000 Btu's with only 1,100 watts in the winter. So heating 60 gallons of water is about 28,000 Btu's or 8 KW. But with my de-superheater, it will provide about 15,000 Btu's of heat for free in the summer, or for $0.10 in electricity in the winter! Saving about 7 or 8 KW (winter or summer) on my daily water heating bill. So about a dollar a day in electricity savings. Then I will be able to heat just my bedroom on most days, and only heat the whole house when I have company over to visit. I expect my electric bill this winter to be about 2/3 of last winter! When I moved in, I asked the lady who moved out what the cost to run the 20 KW electric furnace, she said one winter it cost $400 in January! I have not paid that much any month since I moved in! Not over $140 per month.

6th reason to love a ductless mini-split: THEY ARE SO QUIET!!! MUCH MUCH quieter than a window A/C (aka "window shaker").

[@andrewsnow7386]

Quieter than a window unit absolutely (at least if you are inside the house), but some are much noisier than others. We when we bought our house 10 years ago, it already had a mini-split system in it. It is VERY quiet -- not only the inside units, but the outside section as well. Then a few years ago, our neighbors installed one in there house. Their outside section and ours basically sit on opposite sides of the wood fence between our houses. Theirs is much louder than ours. With the windows closed, you really have to strain to hear ours. Theirs, while I would say it is only occasionally annoying, is very easy to hear. For anyone considering a mini-split system, if you or a close neighbor is sensitive to noisy things, I'd look carefully at not noise level of the inside units but the outside unit as well.

[@emptech]

Another reason to buy one is the efficiency, I don't think that was mentioned. Many are 24 seer, not sure what the higher values are for package units and split units. One reason for the efficiency is that they are using inverter power supplies, the motors are variable speed. I'm not sure of the compressors. The compressors are scroll compressors, don't believe the package and split units are. The comfort level is better, because of the variable speed, they keep a more constant temperature. What is not good, you have to get rid of the condensate. If it is on an outside wall, you can have a drain that goes to the outside that drains by gravity. If it is on an inside wall, you have to have a very expensive pump, float switch, etc, and then pipe the water to the outside or to a drain. The pumps fail, then water runs down the wall. They do not provide fresh air, they only recirculate the air, where some of the other units can add fresh air to the building. I'm sure I can think of a few more things, yes, they are a pain to repair.

Two thoughts: Having traveled in Europe, Asia, and the Mid East for over 20 years, I've seen many mini splits...and many of them 15 to 20 years old...working fine.

One with a single head unit and the other with two heads. Made by/for Carrier. Excellent units. Live in AZ at 5000 feet...they do a good job for both heating and cooling. Economical to run as far as heating and cooling. My units are the ones that will squeeze out heat to -15 f. Never had to do that, but I've had them working great at 5 f. Great video...

I think one of the big things with mini splits is whether you're ok with potentially nasty condensate water dripping off the side of your house on a hot summer day. That's one of the things that a central AC unit takes care of. Also, the eye sore that a lot of HOA nazis will hound you for.

I think the biggest issue with them actually lasting longer is that there's no good techs out there willing to work on them and the tech support for them is usually terrible taking days sometimes to get in touch with the manufacturer.

[@richardcoughlin8931]

Good summary of the issues. I am considering a mini split for a room that is not getting adequate cooling due to a design flaw in the house architecture. One alternative would be to reroute the ductwork to see if that would provide adequate coverage. The quote I got from a local HVAC dealer for a small mini split was $3000. This was a bit more than I expected but it would guarantee good cooling for the room. Rerouting the ductwork may cost as much but not yield satisfactory results. I live in the desert southwest where summer temperatures often exceed 115°F.

This is an opinion piece not a concrete pro/con video ( in my opinion ) You didn't mention the most important part and that's running costs are substantially less compared to central air. If you have solar ( or if you don't ) this is tons cheaper to run year round. And I am at a loss how you say it's more expensive. I was quoted $15k for central air ( with 5 year old new duct work ) from a "HVAC Pro" in my area. FWIW I installed a 5 zone Fujitsu mini split in connection with local electricians and HVAC tech for less the $5500 total. All I did was the labor of installing the pad / condenser / line sets and hung the wall units. It took me about 8 hours by myself to do the install and the next day the lines were charged and running. All permitted and about 1/3rd the cost of what the pro's were trying to sell me on. He also tried to sway me to going central air based on his opinion that split systems were inferior. A year later and I'm glad I went with my gut.

[@BenjaminSahlstrom]

I know that pricing can vary a lot from area to area and I think that is the case here. In our area we charge about $3,500 for a complete AC installation if the house has existing ductwork. To install a similar multi zone mini split system we would charge closer to $6,500. That's more expensive. If we're talking materials only then they are pretty similar in cost with a 2 ton AC condenser, lineset, and coil costing about $2,000 and a 3 zone 2 ton mini split costing about $2,600. ( amzn.to/39fyhEI ) IF we're talking about a new gas furnace and AC then the price would be closer to $6,500. If whole house ductwork was needed then that would be additional and would probably cost another $6,500. I think our area is fairly inexpensive though compared to most. I have a friend who just paid $11,000 for a 3 zone mini split install...

[@jimvano]

@@BenjaminSahlstrom I am sure costs vary by region and level of experience with the technology, but installing ducts is expensive. In new construction, minisplit is the only way to go IMO - cheaper up front and way cheaper to operate. I think the ceiling cassettes are the least visually obtrusive of ductless. If not installing ducts, then only savings may be operating costs. I installed 2 24k three head systems and 1 36k four head system for $15k in three-building new home and workshop. I did electrical, ran linesets, installed condensers, and had HVAC guys install head units, test lines, and commission the systems. Quotes were $40k+ for similar conventional systems.

I have spent a lot of time in China back about 15 years ago. I was amazed at how efficient and quiet mini-splits were. In contrast to most of the A/C units here in the U.S.A.

No expensive duct work. Ben. I have a home in the South. I have a huge unit at the back of the house The duct work runs in a crawl space under the house. In the winter the field mice cut holes in the duct work which is made up of R19 insulation with some kind of foil covering on the outside Then the problem is the repair guys never want to go into a crawl space to repair the ducts.

One major 'Pro' of Mini-Splits I didn't ever consider until a friends ducted system failed on him was the built-in redundancy of having multiple units instead of just one. A now known-fault killed the logic board in his outdoor unit but of course parts were really scarce due to all the others that had also failed plus COVID issues haven't helped either. It's now been over 9 months and he still hasn't got it fixed and has been suffering through a super hot Summer and freezing cold Winter whereby if he just had Mini-Splits he could simply temporarily move out of the room with the affected unit until it was repaired/replaced.

I have a lot of experience as a consumer with mini splits. My town house in Mazatlan, SIN, Mexico, has four mini splits (concrete walls, no duct work), one (big one - high-end LG branded with heat strip) on the ground level and three upstairs (one in each bedroom, smaller units but more than capable in the ferocious humidity of costal Sinaloa). These units can bring the ambient ai teperture down from 32C to 18C in -7 minutes, amazing. Effencity is 1000 times better than a ducted system. IN the day time there is no reason to cool the bedrooms (upstairs). Turn on your BT-enabled air handler about five minutes before you expect to go upstairs to bed and - no worries. You (like me) want it out right COLD in the hot and humaid world that is Mazatlan? The mini can do it - QUIETLY - I've got the master BR down to 14C. It is not all sunshine and roses. Mini's (at least mine) tend to need more attention from guys like you - even in Mexico this costs money. Micro climates. Get used to micro climates, the stairs, the bathrom, whatever. This is wierd but every one has a few. You walk out of the bedroom (which is at a cool 20C into a hallyway that is 30C. Shocking.

[@billlee2726]

Our house is small (1400sqft), with almost no attic space (~1/12 pitch). The 40-year old brown wrap ductwork couldn't be replaced without tearing down the ceilings, and the insulation was so deteriorated we couldn't cool the house anymore in the Florida summer. We went with a mini split with 2 head units - one in the master bedroom, and one in the living room. Overall, we've been very happy, but there were a couple considerations you didn't mention. First, you pretty much have to install the head units to an external wall, or otherwise provide a drain path for the head unit - this can be ugly if you have to run it inside, and so can limit where you can install the unit. Also, if you have a room without a head unit where the door spends a significant amount of time closed (e.g. your teenage son's room), it won't get cool air distributed to it. The unit was more expensive to have installed, and the maintenance is more expensive (head units have to basically be completely disassembled to clean). One last con....these are plastic housings with a fan motor inside - any imbalance will cause minor rattles - no big deal unless it's 2AM and quiet in the room...it can be annoying.

[@BenjaminSahlstrom]

I was first introduced to the mini split concept in an episode of Norm Abram's New Yankee Workshop tv show many years ago. The unit he installed was a Mitsubishi and I think they may have been the first in the US market and pretty expensive too. Norm did not spend a lot of time talking about the mini split and went on with his woodworking project, but the idea continued to rattle around in my brain. Several years later I built a 1000 sq ft garage/workshop for myself and made provisions for a mini split line set to go through the wall plus put in the outside electricals for the compressor. Six hot, miserable summers later I was ready to pull the plug on a mini split, during the winter I did a lot research and determined that 24,000 btu would do the trick and selected a Friedrich brand unit. I installed it myself, but had an HVAC tech check my work and was on hand at start up to check for leaks, add refrigerant if needed and operation. That was in May of 2013 and have been very pleased with my decision. I do not use it for heat as I had put in radiant heat in the floor. The unit has been trouble free (knock on wood) and sips electricity, helped by a well insulated building. That said, I cannot imagine using a mini split in my residence.

We had a Mitsubishi Slim for 10 years here in Southern California. We got the one that only cools. (We wish we had gotten the one that also heats.) But we NEVER had even one day's trouble with that unit. While San Diego normally has great weather, we do have about 10 days out of the year where it will climb to 95 or 100 degrees. We turned on that mini-split and within 15 minutes, the room went from 92 degrees to 68. In the winter, we can get down to the 40s. So we would have to use the regular whole-home heat pump. But the mini-split was VERY quiet. At night we would only turn that on, and never run the standard heat pump A/C that covers the whole house. Finally, we had to get a new whole-home heat pump (that uses ducts) because it was 30 years old. Our house is around 3,000 sq ft and is a 2-story. The farther you are away from the air handler (which is now in the attic), the less air will blow out of the ducts. We ended up remodeling the house and took away a 2nd story deck, which is where that mini-split condenser sat. So we just removed the unit from the bedroom. (It's still outside on the storage shed). But if I had it to do all over again, I would have gotten 2 or 3 mini splits in the house, rather than the $17K (total) for the condenser, new air handler, and more air ducts along with a difficult installation. They kept trying to tell me how new heat pumps will do the "zone" thing that is referred to in the video above. But I didn't want it because it was much more expensive. So eventually, we will probably get a few more mini-splits, and just stop running the main heat pump altogether. But Mitsubishi makes GREAT mini-split units. It was incredibly quiet. Love mine... Sometimes I go out in the shed just to say hi. (Haha... not really... but I DO miss it in the house.)

Could affect the wood itself? whatever paint is on those decks? but mostly, some residents like to put plants on those decks, can't imagine plants will enjoy the 60C temperatures, other residents also like to setup their BBQ on that deck, they fire up the grill and often step out the patio door barefoot to check on it... now seems to me like the deck could be so hot at times walking bare foot on it would be painful, attending the BBQ would be unbearably hot, i have some other issues but i think the smoke alarm is about to go off again so ill leave it at that... again, no questions just... opinions/feedback if you think we're heading for headaches or not etc. and yes... i'm drunk ;) sry for saying deck so much lol, i'm french,couldn't think of a better word :P Edit; here's another thing, in my case i live in a corner unit, i have an outer wall that's connected to my stairwell which makes the installation easy but in some other cases ive seen so far, the machine sits on the ground and the conduits are installed outside the wall(covered by a small plastic channel/cover) and they run all the way to the attic, so that's well over 20 feet of somewhat insulated conduits who are sitting right where the heat coming off the machine rises if there's no wind and then there's the added length going through the attic in order to reach the inside part of the machine... i'm not doing anymore research to determine how having such long conduits will affect the performance, i'm at least certain it won't help :/

[@BenjaminSahlstrom]

Good point.

[@c182SkylaneRG]

So this is the point that I'm trying to verify for myself: I did out the numbers, working backwards from BTUs that my furnace put out last year (number of gallons of oil, times BTUs per gallon, times the system efficiency that the cleaners measured this spring, 84%, in my case). I worked the resulting BTU/year number backwards through a theoretically 300% efficient electric heating system, (Mini-Split), and they came out balanced if the oil price was somewhere around $2.25/gallon (I did 300% and 250% efficiency). This is before the cost of maintenance/installation. This is JUST the cost of heat. I'm racking my brain, trying to figure out if I missed an inefficiency in my oil system somewhere (hydronic baseboard heating with forced hot water from an oil-fired boiler). But I just pre-purchased this winter's 500 gallons of oil for $1.779/gallon, significantly cheaper than the $2.25/gallon equivalent price of the heat pump. (The heat pump price shoots up to $2.70/gallon of oil equivalent if you consider its efficiency to be 250%. Since I want to heat 5 separate locations, and everything advertises "up to 300%", I'm assuming 250% is closer to what I'd see in practice).

Ben you forgot to mention one big Pro for mini split which is it is very DIY friendly. The quality of final install can be argued about but if we look at the number of new skills to be learned by a DIYer , they are less for Minisplit as compared with a traditional system (my home doesn’t have existing duct work)

They are totally worth it. But a quality install is key. And they require maintenance. Yes maintenance. 🤘⚡️🤘

[@jayajora]

What kind of maintenance?

[@NorCal-refrigeration]

Alicia Jorawar the indoor coil and blower wheels get dirty. Real dirty over time and the condensate drains will also get plugged. So I recommend they be cleaned annually. There are many videos on KZbin you can check out to see what it looks like.

I have a four head unit Gree mini split and saving 30% on my electric. Works great and will pay for its self before it wears out. You didn't say anything about how efficient mini splits are. When I can save 30% less in electric than what a central unit was costing that is a win win for me.

Where do you live? Wondering if where I live -- Chicago area -- if savings would show in electric?

[@popholmes5825]

@@marypikul3700 You should see savings doesn't matter where you live. Here in Alabama when the temp gets below 20 in the winter it struggles to keep house warm. In Chicago you may need a little backup heat. In summer when the temp is 90 and above it keeps my house nice and cool. Do your research talk to people who own them in your area. Talk to people that install them. The one I have is great would never go back to a central unit.

Thanks for this video! I live in D.C. and need to replace a really, really old furnace and ac. The company that made the current unit hasn’t even been in business since 2001 and this thing looks like it was made long before then. I’m actually amazed at how well it was made! But I digress... The problem is that I want to move the furnace to a corner of my basement. Right now, the placement takes up what could technically be another small room. Because of this, the technician said I could go with either moving the duct work/ installing bulk heads and installing a traditional furnace & a/c OR I could install mini splits on each floor. He said it would be pretty much the same cost and it would free up that space I want to use in the basement. Currently trying to determine what’s best for my home. If anyone has any advice, please let me know. Thank you!
