Hard to find a well planned job like this, I've searched for some time to find a comprehensive solution like this. An electrical outlet and surge protection just for good measure.

I just finished renovating my house. I got 3 quotes from hvac contractors to install these mini splits. I was in shock by the price. For a 3 zone air handler hooked up to 1 condenser with a very easy run [less than 20ft] per line set, I was quoted up to 16K! The lowest proposal was 11,800. That was also with all of the walls open.My advice to anyone wanting these is do a lot of homework on installation and just buy the unit yourself. Doing so saved me at least 7-10k
@@frankgall6 could not agree more. I know someone who installed a MR. Cool on his own to save money. Found 35’ of pipe coiled behind condenser blocking air flow let alone the oil trap the coil made. Then he also installed a three zone where the saturated vapor line blew out of the flare nut releasing 7 lbs of R-410 into his yard and compressor oil all over his siding.

@@colbraddock9913 perhaps. You have a 30 degree drop from ambient in the air coming out of the unit, but that doesn’t mean you have to set your thermostat at 30 degrees below ambient. What did I miss?
These things are crazy efficient. If you have been running a bunch of window units all summer you will be shocked at how much your electric bill goes down when you have these installed. You can also get bigger ones that flush mount into the ceiling for larger spaces. The only rub is that when you use them in winter they do still start losing their heating efficiency/effectiveness when the temp drops below freezing. You can get ones that are specially designed to work better in cold weather, but for very cold climates you are still likely going to want some form of back-up heat.
Living in the hot, humid Southeast, it's ability to cool efficiently is my priority. The biggest problem is sizing any unit. What is recommended is a joke. You either almost double the recommended size or it can't overcome the heat when you need it the most. I learned that the hard way, TOO MANY TIMES.
@@allenh7835 Correct and if you go too big it will overcool and you'll end up with high humidity. And they never flash the exterior correctly so outside air comes pouring right on in.

To my way of thinking, condenser's should always be set two to three feet above the ground on a regular base's, especially if you have a heavy snow or major leaf problem. The damage done by winter snow year after year along with salt, like any other metal product is really bad for the long term use. The leafs should be enough of a reason because you are constantly having to clean up the unit to keep it from being plugged up for good ventilation through the evap and cooling of the compressor. Just makes more sense to me, but it does make installation and servicing a little harder, which is why I think they always put them on the ground.
@Tony Po A 5,000 BTU window unit is inexpensive. However a decent mini split at 12,000 BTU is only about $700 and will cool and last a lot longer. I just bought two a few weeks ago in a property in the Caribbean. They were branded as York, one 9,000 BTU and another 12,000 BTU. $1200 including installation.
I'm in New York. I'm a certified HVAC Tech. I usually charge $1,700 to install a single zone mini split unit ( Labor cost only ). Customer buys the system of their choice.
i had these in my rooms in my apartment while i lived in japan and i loved them. i'm now back in the States and have just the normal 1 central AC for my whole townhouse. it works fine except for my 1 computer room on the third floor. rest of the third floor is pretty fine, it's just the computer room with my PC pumping out heat combined with the fact that heat rises. thinking about adding a small one of these to that room as I spend a lot of time in there. they really are great
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) ua-cam.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.
LOL, we first used split system in 1995. At that time, nobody used window units in my country. Right now, people in my hometown still use split units. Newer condo units are using central. It's funny you can still buy window units in America as of 2021.
@@whoeverwhoever400 window units are pretty cheap. If I weren’t worried about creating a security weak point, an entry point for pests, and being an exterior eyesore I would definitely consider one. My grandparents had one in the 80s and that thing was a beast.

This is a really good way to cool off your house if you don't have central air conditioning, I would think these units are best for small spaced areas like garages, workshops, shops, and much more, when I grow up I am would like to be an HVAC technician.
I just started as an HVAC tech at 31 years old and I wish I had done it sooner. It's very challenging yet very rewarding work and it pays very well. Not to mention being able to do work on your own house and not having to pay for someone else's labor can save you tens of thousands of dollars!
I ordered a "Mr. Cool" 12000 btu unit from Lowes and it arrived at the store today. Going to pick it up on Sunday. Mine is for the garage as well but I also have to do some blown-in fiberglass above.
We have a Mitsubishi Mr. Slim installed in an non heated/AC room (I often don’t use the house AC since Mr. Slim unit cools the entire 1st floor of house & less expensive to use). It’s amazing, love it. It’s extremely quiet inside & out (walking past condenser I barely know it’s running). Highly recommend split units to anyone who doesn’t have AC.
Hello my question is. Did you add or take out take freon from the heat pump? I understand that you added nitrogen and vacuum the line or the pre charge unit is just good enough for plug and play?
Units come precharged from the factory. Nitrogen is added to perform a leak check. If there is no leak, the nitrogen is released and the lineset is vacuumed to below 500 microns. The refrigerant is then released into the lines.
Really a great video! I live and are the owners of a 2 family house in NY that uses regular window A/C for the summer and brand new Pearless Steam Boiler for system radiators. Problem has always been that the steam radiators get hot in the lower apt but the upstairs apt is always cold. In order to make them comfortable we have to almost turn on our A/C during the winter. So we were thinking about installing a split system for the upstairs APT.
Your steam system imbalance needs to be addressed. Pick up a copy of "The Lost Art of Steam Heating" by Dan Holohan, and you'll probably find examples of whatever in your system needs to change. Its either bad vents/traps, improper vents/traps, or improper near-boiler piping...or a combination. Your pipes were designed by the dead men who first fit them to heat evenly from the start. I'm going through this now, have the venting set up pretty good but my near-boiler piping is terrible and the unit is oversized relative to the capacity of the radiators, so I'm just here hoping the boiler springs a leak before the gas valve goes from all the pressuretrol cycling.
Still amazes me how long it’s taken the US to start using this type of aircon unit like it’s the latest greatest thing when the rest of the world has been using them for decades.
Well actually most air conditioners in the US are Central forced air. But the main population that has no access is everyone in populated cities who live in high-rises would have no place to put their units. So everyone is stuck with the regular window AC.
Mini splits have been used for last 25 to 30 years in USA. They are more of a pain to service and they also tend to grow mold at times. This is cause all mini splits have very poor filtration. Merv 4 at best so that makes them high maintenance. They need to have a deep clean more often than traditional split systems with ducts
Yes. I have exactly that in my house. Each of my 3 bedrooms have a head unit and they are all connected to a single outdoor unit. They can all be controlled independently.
Ducted mini-splits are perfect for this purpose. One head per room doesn't work well because the load for each room is too low so the units will be short-cycling all the time, which hurts durability and efficiency a lot.
That is LG Dual inverter which one of the best mini split in the market , I have one of that in my living room ,that is good to see people starting buying mini split air conditioner system, its 100% better and save a lot of money more than central AC conditioner
When you hung the outside condenser on the vinyl wall, can you explain exactly how you did that? What kind of screws and bolts? Did you go into concrete or wall studs? How exsctly do you protect the vinyl siding? How can you be sure your rig will be strong enough to hold the weight of the unit? Sorry if these are noon questions!
Thanks Richard, Would like to know more about designing a heat pump system. How well will that single indoor (evaporator) heat the downstairs unit given all the room dividers?
They get mold on the fins inside if your climate is very humid. In Australia cleaning involves surrounding the unit with a plastic catcher & spraying cleaning foam then rinsing. There are companies that do this. There are removable filters inside that catch dust & I rinse these off under the laundry tap.
Question, does the clearance from the condenser to the wall matter? cuz I have a senville ill be installing and it says 12" clearance from the back wall but the wall mount that come for it gives me like 4 1/2" clearance, all other clearances are good just that one, Thanks
I have the exact same problem now. Mini splits says 12" from wall on back and same company sells wall bracket with only 4" from wall. Very confused and don't know if will make much difference.
In Cyprus all I mean ALL houses have mini splits but most of us use them only for cooling but some people who don’t have central heating also use them as heating
Mini-Split are awesome, installed a diy unit my self. Was not to bad to install, would have been easier with a 2nd pair of hands. Heats a small 400sq to 65, with outdoor been 10-20 in new England weather. It only added $60-70 to the electric bill.
I put a Bosch unit myself into the converted garage, but I did get a pro to pull the vacuum and charge it. Then I hired a company to install a 3 head unit, and yeah they did run the lines on the outside and ruin the looks of my house. Couldn’t belief it. Should have done it myself.
@@generallyhelpfulsoftware646 I ran my line up throw the attic crawl space, and cover up the drain line with a drier vent. I want it to look as clean as possible.

Im gone to make something to better protect the out door unit for nor Easter of heavy snow, i notice the past few storms it work a bit harder because the snow got on the coil a bit, nothing bad but i like to put something in place just incase.
Any advice on getting a larger unit mounted? The one we are installing weighs 160lb. We have the rated bracket for it but we need to get it up to the 2nd floor back wall of our condo building.
In Australia they use a small electric tbar lift. You can probably hire one. I had my outside units placed right up under the eves opposite the inside unit.
to save money you can buy the unit and do 90% which is placing the unit on the wall running all the lines through the basement to the outside unit. then run the electrical from outside unit to the fuse box and secure all the lines to code. make sure you read your local code as they may very from state to state or county. the only thing the hvac guy will have to do is finish hooking up the lines test the lines fill up the lines. then electric guy comes out and hooks up the electric preferably before hvac. this will save you a lot of money as you do all the work id probably say it would cost $3,000-$6,000 on the unite and $1,000 on the hvac and electric guys vs if they did it all $6,000-15,000.

Length requirements depend on the manufacturer. There are minimum line lengths (many times 10’) and a maximum based on the model. The smaller Fujitsu units max out at 64’, the larger single zones at 164’.
I have a question I’ve installed mini splits I bought the Yellow Jacket 19173 5/16" Female Quick Couplers x 1/4" Male Flare adapter for my yellow jacket 1/4 HVAC hoses my question is when you break the vacuum after releasing the refrigerant from the mini split condenser into the line set when I go to remove my suction line hose from the suction line service port on the mini split a lot of refrigerant comes out squirting , what adapter do you use for mini splits for your HVAC hose to connect to mini split 5/16 service port
The one thing I didn't like is how you try to scare homeowners away from doing it themselves! I have 3 units on my house Mr slim with 4 head units pioneer with two and another Mr slim with single head, I did the installation myself to get rid of the energy sucking 5 ton unit which is still in place but turned off. With some reading and specially now with UA-cam instructional videos some homeowners can do this.
I already have a minisit install in garage. I have the outside unit on 4x4 on floor. I wanna mount it a few inches high on wall since they are pouring concrete on floor. Us there a way to do this without disconnecting any hoses?? Thank u
Funny that this would be on an Old House segment when many of us have naturally-stained, all-wood interiors in our Arts & Crafts homes. And white would stick out big time. It would be nice if these mini-split companies would have optional wood covers that you can stain to match or pick a stain color.
Most people that have homes that nice would probably want to have something custom built to match their existing woodwork anyway... just hire a cabinetmaker (or a finish carpenter that specializes in old homes, etc) to build a cover for it that will vent the air out but hide the wall unit itself.

He said the drain line would be run “with pitch” to allow gravity to do its work. However, they snugged it up to the floor joists. Perhaps the house leans and that’s how they utilized pitch.
at 5:31 the corrugated lineset is still dangling down to go out a diff area of the house. The linest tubes are strapped together going the other way. I had to look twice too lol
I see what you're saying but once the line fills with liquid it will create a siphon that will drain regardless of pitch. It's not ideal but better to have a couple low points for liquid to seal the line and keep critters from crawling up in
Great video. What did they do for HVAC in the master bedroom? Also, do you know if any of the wall mount systems will allow you to connect the lines from the top coming down out of the attic?
Yes. I would have opened up that wall and nailed some 2x4’s for bracing situated in position so that it supported the unit then covered the hole I made with the unit and it’s bracket. If need be I would have repaired the drywall before mounting the unit. Additionally I would have used a 2 1/2” wood screw. No way I would have trusted the way they mounted it with drywall screw into nothing. Hell I wouldn’t even trust that drywall screw to hold up a picture frame.
The head units way like 10 pounds....come on man! 1 screw in a stud with some others to stabilize and level and its not going anywhere. Mine are set that way and haven't moved for years. Now, if he set the condenser that way i'd agree with ya.

how much noise makes its way through and in the wall it’s self? and how to build a solid frame work that limits the vibs and sound? if a car driving by can rattle your windows and not even be all that loud to start with as the “heavy” base sound goes right through walls made of wood.
I wouldn't use the wall mount, ppl have said it can put a light weird vibration in the house. Its easy to put a paver and pad location to anchor to, it can be elevated if you need aswell.
I'm having a whole house system installed this week. It's thru an energy saving program in my state. I sure hope they know what they are doing when they get here tomorrow. I'm somewhat nervous about the whole thing. I have done a fair amount of research on these systems. My main concern is where the heads will be located. If not done properly, it will not be energy efficient. Wish me luck!

I need to lift my sinking house but my outdoor unit is placed on the ground. Do I absolutely need to decommission the outdoor unit before lifting the wall? I only need to lift the wall by 7cm or max 10cm. Can I just lift the outdoor unit slowly as I lift the wall?
You could do a pump down to trap all the refrigerant in the outdoor unit, so that you could disconnect the line set. You would also need an hvac vacuum to vacuum out the line set and indoor unit before reconnecting it.
I got estimates in Massachusetts for a ductless mini split for my home. For a 5 indoor unit system, the lowest estimate was $25,000, the highest estimate was $35000. I am not allowed to DIY in my town because you need building permits. Only a licensed electrician is allowed to pull an electrical permit, and only a licensed HVAC techinician is allowed to pull an HVAC permit. I can pull a regular building permit. I decided to keep the window units. If it's on TOH, it's not affordable to the common person.
you need to find another HVAC guy to give you a better estimate. Find out what he likes to earn per hour, then multiply that by the time required. That gives you your reasonably fair labor cost. Add that to the equipment cost. Do NOT let anyone add a third component to the price, their profit or whatever they think they can get away with because they've greatly improved your indoor climate.
@@davidlindgren2448 I got 3 estimates, (1 big box store, 1 local hvac company, 1 regional hvac company), all were in the same price range. I'll keep using the window units.
U throw in a couple to level the bracket, then find studs. That guy definitely wasn’t a hack. Although that evacuation set up is what we did 10-15 yrs ago, not what super techs use today 😉
Yea, probably the 5 screws that are included in the hardware kit. These units are incredibly light and have next to no vibration. The LG manual doesn’t specify any anchors or a stud. This will hold just fine with those screws. Anyone who thinks this think has to be lag bolted to structure has never seen one of these being installed.
All are manufactured in Asia...they only last an average of 10 years Plus or minus..not all techs are familiar with these so it is more expensive to service and maintain...parts are not readily available and may need to be special ordered...we need pros and cons for these units to make a proper decision...
So get a Japanese Mitsubishi - the absolute best you can buy. Asian manufacturing is top notch, as long as you’re not talking about the lower end Chinese Mr Cool/Pioneer/etc. Mini splits.
How long have these been around as I remember as a kid in the 80’s my church the LDS church in Brandon FL had these in the bishops office so when they came in to do clergy work they would not have to cool the whole church building. It was just outside the office. It was a Mitsubishi brand if I remember right. Circa 1988.
The heating efficiency varies quite a bit from 300% to 530% (47F outside 70F inside). And of course it goes down from there. When in heating mode it's important that the outside unit is elevated so it doesn't sit in its own cold air, snow or leaves. Efficiency is also lower when it's running at full bore.
I was hoping for a good example of installing a split condenser. This was a fail. The various manufacturers specify 12" clearance from the wall. This looked like maybe 4 or 5" at best.

The leafs should be enough of a reason because you are constantly having to clean up the unit to keep it from being plugged up for good ventilation through the evap and cooling of the compressor. Just makes more sense to me, but it does make installation and servicing a little harder, which is why I think they always put them on the ground.
Leafs? You think "leafs" is a word and you want to give technical advice? SMH
Mini splits are the best! Another added benefit is when it is time to replace the units it a lot less money and easy to do.
@Tony Po A 5,000 BTU window unit is inexpensive. However a decent mini split at 12,000 BTU is only about $700 and will cool and last a lot longer. I just bought two a few weeks ago in a property in the Caribbean. They were branded as York, one 9,000 BTU and another 12,000 BTU. $1200 including installation.
I'm in New York. I'm a certified HVAC Tech. I usually charge $1,700 to install a single zone mini split unit ( Labor cost only ). Customer buys the system of their choice.
i had these in my rooms in my apartment while i lived in japan and i loved them. i'm now back in the States and have just the normal 1 central AC for my whole townhouse. it works fine except for my 1 computer room on the third floor. rest of the third floor is pretty fine, it's just the computer room with my PC pumping out heat combined with the fact that heat rises.
thinking about adding a small one of these to that room as I spend a lot of time in there. they really are great
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) ua-cam.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.
These Split AC units are the future. We've been using them in Asia for decades and couldn't ask for anything better
Not here in the US. Here if we can afford central forced air and have the physical ability to use it it's what we always use.
LOL, we first used split system in 1995. At that time, nobody used window units in my country. Right now, people in my hometown still use split units. Newer condo units are using central. It's funny you can still buy window units in America as of 2021.
@@whoeverwhoever400 window units are pretty cheap. If I weren’t worried about creating a security weak point, an entry point for pests, and being an exterior eyesore I would definitely consider one. My grandparents had one in the 80s and that thing was a beast.

This is a really good way to cool off your house if you don't have central air conditioning, I would think these units are best for small spaced areas like garages, workshops, shops, and much more, when I grow up I am would like to be an HVAC technician.
I just started as an HVAC tech at 31 years old and I wish I had done it sooner. It's very challenging yet very rewarding work and it pays very well. Not to mention being able to do work on your own house and not having to pay for someone else's labor can save you tens of thousands of dollars!
I've been thinking about a split unit for my garage. To keep it warmer in the winter and cooler in the summer.
I ordered a "Mr. Cool" 12000 btu unit from Lowes and it arrived at the store today. Going to pick it up on Sunday. Mine is for the garage as well but I also have to do some blown-in fiberglass above.

How do you clean the inside unit
We have a Mitsubishi Mr. Slim installed in an non heated/AC room (I often don’t use the house AC since Mr. Slim unit cools the entire 1st floor of house & less expensive to use). It’s amazing, love it. It’s extremely quiet inside & out (walking past condenser I barely know it’s running). Highly recommend split units to anyone who doesn’t have AC.
Does your split have a heater ? How is it ?
Had them when I lived in Hawaii. They were great!
Hello my question is. Did you add or take out take freon from the heat pump? I understand that you added nitrogen and vacuum the line or the pre charge unit is just good enough for plug and play?
Units come precharged from the factory. Nitrogen is added to perform a leak check. If there is no leak, the nitrogen is released and the lineset is vacuumed to below 500 microns. The refrigerant is then released into the lines.
Nice video. Thank you. Think I am going to have to do one of these in my house due to rodent contamination in the forced air unit and crawl space.
What if they are mounting the outside unit to stucco rather than to siding?
Really a great video!
I live and are the owners of a 2 family house in NY that uses regular window A/C for the summer and brand new Pearless Steam Boiler for system radiators. Problem has always been that the steam radiators get hot in the lower apt but the upstairs apt is always cold. In order to make them comfortable we have to almost turn on our A/C during the winter. So we were thinking about installing a split system for the upstairs APT.
Your steam system imbalance needs to be addressed. Pick up a copy of "The Lost Art of Steam Heating" by Dan Holohan, and you'll probably find examples of whatever in your system needs to change. Its either bad vents/traps, improper vents/traps, or improper near-boiler piping...or a combination. Your pipes were designed by the dead men who first fit them to heat evenly from the start. I'm going through this now, have the venting set up pretty good but my near-boiler piping is terrible and the unit is oversized relative to the capacity of the radiators, so I'm just here hoping the boiler springs a leak before the gas valve goes from all the pressuretrol cycling.
It might be the valve caps, simple fix
Still amazes me how long it’s taken the US to start using this type of aircon unit like it’s the latest greatest thing when the rest of the world has been using them for decades.
Well actually most air conditioners in the US are Central forced air.
But the main population that has no access is everyone in populated cities who live in high-rises would have no place to put their units. So everyone is stuck with the regular window AC.
Mini splits have been used for last 25 to 30 years in USA. They are more of a pain to service and they also tend to grow mold at times. This is cause all mini splits have very poor filtration. Merv 4 at best so that makes them high maintenance. They need to have a deep clean more often than traditional split systems with ducts

Can you use a mini split to cool multiple rooms. For example one outside unit with 3 inside for lets say 3 bed room?
Yes. I have exactly that in my house. Each of my 3 bedrooms have a head unit and they are all connected to a single outdoor unit.
They can all be controlled independently.
@@_valxp thanks. I will look this up before summer hits
Ducted mini-splits are perfect for this purpose. One head per room doesn't work well because the load for each room is too low so the units will be short-cycling all the time, which hurts durability and efficiency a lot.
Super question .
That is LG Dual inverter which one of the best mini split in the market , I have one of that in my living room ,that is good to see people starting buying mini split air conditioner system, its 100% better and save a lot of money more than central AC conditioner

When you hung the outside condenser on the vinyl wall, can you explain exactly how you did that? What kind of screws and bolts? Did you go into concrete or wall studs? How exsctly do you protect the vinyl siding? How can you be sure your rig will be strong enough to hold the weight of the unit? Sorry if these are noon questions!
Wall studs.
Thanks Richard, Would like to know more about designing a heat pump system. How well will that single indoor (evaporator) heat the downstairs unit given all the room dividers?
I'm putting one of these in next year started kind of running conduint this year.. lot more work to do..
Do these get mold like air conditioners and you have to clean them regularly
They get mold on the fins inside if your climate is very humid. In Australia cleaning involves surrounding the unit with a plastic catcher & spraying cleaning foam then rinsing. There are companies that do this. There are removable filters inside that catch dust & I rinse these off under the laundry tap.
Question, does the clearance from the condenser to the wall matter? cuz I have a senville ill be installing and it says 12" clearance from the back wall but the wall mount that come for it gives me like 4 1/2" clearance, all other clearances are good just that one, Thanks
The manufacturer will tell you the minimum. Check out the installation instructions.
I have the exact same problem now. Mini splits says 12" from wall on back and same company sells wall bracket with only 4" from wall.
Very confused and don't know if will make much difference.

Any advice on getting a larger unit mounted? The one we are installing weighs 160lb. We have the rated bracket for it but we need to get it up to the 2nd floor back wall of our condo building.
In Australia they use a small electric tbar lift. You can probably hire one. I had my outside units placed right up under the eves opposite the inside unit.
to save money you can buy the unit and do 90% which is placing the unit on the wall running all the lines through the basement to the outside unit. then run the electrical from outside unit to the fuse box and secure all the lines to code. make sure you read your local code as they may very from state to state or county. the only thing the hvac guy will have to do is finish hooking up the lines test the lines fill up the lines. then electric guy comes out and hooks up the electric preferably before hvac. this will save you a lot of money as you do all the work id probably say it would cost $3,000-$6,000 on the unite and $1,000 on the hvac and electric guys vs if they did it all $6,000-15,000.

Is there any distance limits between the two pieces of equipment when installing the units?
Shorter the better. Big thing to consider is the amount of refrigerant changes based on the line length.
Yes
25 feet per manufacturer. You could go longer but you have to add more refrigerant.
Length requirements depend on the manufacturer. There are minimum line lengths (many times 10’) and a maximum based on the model. The smaller Fujitsu units max out at 64’, the larger single zones at 164’.
I have a question I’ve installed mini splits I bought the Yellow Jacket 19173 5/16" Female Quick Couplers x 1/4" Male Flare adapter for my yellow jacket 1/4 HVAC hoses my question is when you break the vacuum after releasing the refrigerant from the mini split condenser into the line set when I go to remove my suction line hose from the suction line service port on the mini split a lot of refrigerant comes out squirting , what adapter do you use for mini splits for your HVAC hose to connect to mini split 5/16 service port

Funny that this would be on an Old House segment when many of us have naturally-stained, all-wood interiors in our Arts & Crafts homes. And white would stick out big time. It would be nice if these mini-split companies would have optional wood covers that you can stain to match or pick a stain color.
Most people that have homes that nice would probably want to have something custom built to match their existing woodwork anyway... just hire a cabinetmaker (or a finish carpenter that specializes in old homes, etc) to build a cover for it that will vent the air out but hide the wall unit itself.

how much in labor was that install
He said the drain line would be run “with pitch” to allow gravity to do its work. However, they snugged it up to the floor joists. Perhaps the house leans and that’s how they utilized pitch.
at 5:31 the corrugated lineset is still dangling down to go out a diff area of the house. The linest tubes are strapped together going the other way. I had to look twice too lol
I see what you're saying but once the line fills with liquid it will create a siphon that will drain regardless of pitch. It's not ideal but better to have a couple low points for liquid to seal the line and keep critters from crawling up in
that basement was amazing
Great video.

With the wall bracket it is really not far enough away from the wall to allow good air circulation through the unit. Melt my poor vinyl siding maybe.

Does it have an RJ45 IP control vía wire ethernet too? I don't like they only offer them with wifi.
Anyone else cringing because he mounted the inside unit with drywall screws?
And the one they showed going in didnt hit a stud, not even the lathe
Yes. I would have opened up that wall and nailed some 2x4’s for bracing situated in position so that it supported the unit then covered the hole I made with the unit and it’s bracket. If need be I would have repaired the drywall before mounting the unit. Additionally I would have used a 2 1/2” wood screw. No way I would have trusted the way they mounted it with drywall screw into nothing. Hell I wouldn’t even trust that drywall screw to hold up a picture frame.
The head units way like 10 pounds....come on man! 1 screw in a stud with some others to stabilize and level and its not going anywhere. Mine are set that way and haven't moved for years. Now, if he set the condenser that way i'd agree with ya.

What is the recommended distance from the wall to the unit? Wouldn't that be too close?

Where was this when looking on how to install one of these mini splits...
how much noise makes its way through and in the wall it’s self?
and how to build a solid frame work that limits the vibs and sound? if a car driving by can rattle your windows and not even be all that loud to start with as the “heavy” base sound goes right through walls made of wood.
I wouldn't use the wall mount, ppl have said it can put a light weird vibration in the house. Its easy to put a paver and pad location to anchor to, it can be elevated if you need aswell.
Up to 12000 it is probably ok, bigger than that you can turn the whole wall assembly into a soundboard. Especially if you use it to heat.
Could a unit like that run 2 or 3 different inside units?
they make bigger condensers for multiple zones

I need to lift my sinking house but my outdoor unit is placed on the ground. Do I absolutely need to decommission the outdoor unit before lifting the wall? I only need to lift the wall by 7cm or max 10cm. Can I just lift the outdoor unit slowly as I lift the wall?
You could do a pump down to trap all the refrigerant in the outdoor unit, so that you could disconnect the line set. You would also need an hvac vacuum to vacuum out the line set and indoor unit before reconnecting it.
"We utilize blocking behind the brackets to protect the vinyl siding."
"Then we commence the drilling!"
They put blocking there so it would not crush the vinyl siding since it is not solid like wood.

I got estimates in Massachusetts for a ductless mini split for my home. For a 5 indoor unit system, the lowest estimate was $25,000, the highest estimate was $35000. I am not allowed to DIY in my town because you need building permits. Only a licensed electrician is allowed to pull an electrical permit, and only a licensed HVAC techinician is allowed to pull an HVAC permit. I can pull a regular building permit. I decided to keep the window units. If it's on TOH, it's not affordable to the common person.
you need to find another HVAC guy to give you a better estimate. Find out what he likes to earn per hour, then multiply that by the time required. That gives you your reasonably fair labor cost. Add that to the equipment cost. Do NOT let anyone add a third component to the price, their profit or whatever they think they can get away with because they've greatly improved your indoor climate.

Yea, probably the 5 screws that are included in the hardware kit. These units are incredibly light and have next to no vibration. The LG manual doesn’t specify any anchors or a stud.

Today on Ask This Old House: How to install a mini-split!
Step 1: Call a HVAC contractor
As an HVAC mechanic myself I agree.
All are manufactured in Asia...they only last an average of 10 years Plus or minus..not all techs are familiar with these so it is more expensive to service and maintain...parts are not readily available and may need to be special ordered...we need pros and cons for these units to make a proper decision...
So get a Japanese Mitsubishi - the absolute best you can buy. Asian manufacturing is top notch, as long as you’re not talking about the lower end Chinese Mr Cool/Pioneer/etc. Mini splits.
You must be fun at parties.
How long have these been around as I remember as a kid in the 80’s my church the LDS church in Brandon FL had these in the bishops office so when they came in to do clergy work they would not have to cool the whole church building.

"Protect the vinyl siding" next shot is a hole saw to the vinyl siding
Why do you have to be such a Debbie Downer!!!!
They are expensive to run in winter time(Vermont and still need backup heat) My electric went $100 a month to $440
The heating efficiency varies quite a bit from 300% to 530% (47F outside 70F inside). And of course it goes down from there. When in heating mode it's important that the outside unit is elevated so it doesn't sit in its own cold air, snow or leaves. Efficiency is also lower when it's running at full bore.
I was hoping for a good example of installing a split condenser. This was a fail. The various manufacturers specify 12" clearance from the wall. This looked like maybe 4 or 5" at best.
On the wall you can do 6" typically because air can flow in from the bottom, which it can't do when the unit is right on the ground.
