Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) czcams.com/users/postUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.
That was a great overview of a multizone install. Not a lot of fluff. Good basic information. Thanks for posting this.
We're glad you found it helpful, Bobby!
Thanks, I wish I could save
There's not a lot of content on the multi zone mini splits
We aim to change that!
How did the lines get from the multiple indoor units to the outdoor compressor?
When vacuuming, did you just use an adapter or do I need to buy a core valve removal tool?
can someone help me only one indoor unit is working, the other two aren’t what did i do wrong
my air con has a humming sound that osilates up and down with only a few second intervals, what is causing that? thx. btw it is extremely annoying and I cant sleep with the air con running. Also the condensation pump makes a hell of a noise everytime it turns on.
Thanks for the very well explained presentation...
All that I have seen with the ductless system, so far, have been retrofits; but I am yet to see a clean installation for a new project. Bearing that in mind, the mounting walls always seem to be exterior-walls-preferred.
In new construction, mounting on an interior partition could offer more flexibility; so my question is: Is a 3" PVC pipe located in a 3-5/8" stud wall sufficient to run all those lines from each a/c head? or can each of those lines just freely run in the walls uncovered? And lastly: If then running those lines under a slab-on-grade, what diameter PVC chase would you recommend as a minimum?
I suppose that with proper planning the condensate drain line could follow is own path, or even drain to indoor plumbing.
Yes, the lines can run freely through the walls without piping, just be sure there are no cuts or holes in the insulation. In regards to the cover, a 3" PVC pipe would be sufficient if you chose to use one. The drain line can follow its own path (many opt for turning it directly outside near the unit) even to indoor plumbing, as long as it is slanted downward enough to enable gravitational drainage. If you're unable to angle it downward or need to pull the water upward, you'll need a drain pump.
Does that answer all of your questions? Let us know!
@@CooperandHunterusa This system is even more flexible than I thought... So are you saying that if I ran the lines under a concrete slab, that 3" diameter is enough to fish those lines?
I am also in Florida, by the way.
@@Troy-Moses If the line sets for your unit are 1/4"-3/8" it would be possible to run in 3" PVC. But you will need to be careful with the angles, opting for 45° instead of 90° could be a good idea. If your lines are 1/4"-1/2" or larger, it would be better to use 4" or wider PVC to avoid any kinks in the lines.
Just to be clear, you will need to run one PVC per line (per indoor unit) as multiple lines will not fit/run through the same PVC. Our line sets come pre-insulated, but if you choose to use third party line sets, you'll need to make sure that BOTH copper pipes (high and low side) are insulated before running them through the PVC.
@@Troy-Moses We hope this information is helpful! If you need quicker answers, please feel free to call out tech support team at (786) 953-6706
Does the kit come with the connectors to re-flare the lines?
Nice and clean,thanks for the aducation
Thanks, Esmail!
is A & B connected together through the compressor? Or does A have to be vacuumed separate from B? If A springs a leak, will B lose its Freon also?
I'm looking to replace many old window mount air conditioners with a muti-zone mini split system in a single family home. How do you select system size and the size of the units for the individual rooms? My room sizes vary greatly.
Hi Paul! There are some fairly useful mini split sizing guides on the internet for initial reference. Then we'd recommend verifying whether the capacities are accurate or not with the distributor/seller. If you have any issues with this, feel free to contact our Technical Support team at (786) 953-6706 Mon-Fri 9am-5pm Eastern Time.
Except you could install zones aka electronic dampeners and control to heat or cool these zones to individual preference as well much cheaper than the 3000 dollars in equipment you'll need on a mini split. Not bashing the mini split cause I think theyre great in apartments with no ducts and not much room for thrm
You definitely make some valid points, raptorms773. But, as you probably know, there are many variables for homeowners to factor in when deciding which solution will be a better long term solution for their needs.
It's winter here, Just finished install. Can I use the heater option before vacuuming testing and opening the valves for the a/c
No, you can't. For details, please get in touch with our technical support team at (786) 953-6706 between 9am and 5pm, Mon-Fri.
are you able to pull a vacuum from each individual line (zone A,B,C ..etc) independently of the the main line before opening the refrigerant? example pull a vacuum from Zone A open the low and high pressure, then open the main line to the unit to feed the refrigerant.
Yes, that is correct!
Also need a micron meter and torque wrench for fittings.
Good point! Thanks for watching & sharing :)
From the looks of it, will all three rooms need to have a separate hole drilled out to the condenser, or is it possible to stuff the three lines into one hole with a bigger diameter? If that’s okay, which is better for looks?
Hi Robert! Yes, you could make only one hole, but then you'd have to run your lines INSIDE the house (instead of outside), and that probably wouldn't be very nice from an interior design perspective. In some cases, people run the lines up to the attic before directing them outside.
Do you have to use A zone or can you just use b and c
Hey there Mxrider21! You don't have to use A zone. Feel free to skip to zone B and C if the valve sizing is better for you.
Do the multizone condensers share the refrigerant across all zones? If you pull the vacuum from one zone, is it also drawing down on the other zones too?
If each zone's valves are open, then yes, refrigerant will be drawn from all of them.
Where are u located in Florida ? Can I pick it up locally
Hey T-DUB, you can find a distributor locator on our website www.cooperandhunter.us
We have lots of distributors in Florida.
Nice video. I am going be installing a dual system one for the lower level and one for the master bedroom upstairs. How do I figure what size unit i would need?
Thank you! You should call your local HVAC technician to provide the best suggestion based on your needs.
Seems like a common error even in the Kelvinator really annoying then after diagnostics and parts you have paid for a new one it's discusting.
Do you have to used the remote control to control the system? If remote control is lost will any other remote control work?
Our Wall Mounted units can be controlled either with the remote or via WiFi (C&H kit compatible with Samsung and IOS)
Other models, like the Ceiling Cassette can be controlled with a remote or wired thermostat.
Do you have a video showing how to test each line individually?
Are the Exv’s normally open?
No, we don't. But you can get in touch with our technical support team at (786) 953-6706 between 9am and 5pm, Mon-Fri, and they'll be happy to answer any questions you may have.
Hello please what’s the wattage of the unit at max temperature
Hi James! There are a lot of factors which would determine the wattage of the unit at max temperature. For example, the capacity of the unit, the number of zones you are working with, and various combinations should be taken into account.
If you'd like, you can provide some more details here or call our Technical Support line at (786) 953-6706 (Monday to Friday, 9am - 5pm)
Are these pre charged?
Yes, they come pre-charged for a specific line set length.
I just finished connecting everything for my Cooper and Hunter mini split but I have a question before vacuuming the line set. I had to use the copper adapter for the line set for the 18k head unit on the outdoor unit, however I noticed there are small copper flared rings that come with the bag with all the adapters. They fit perfectly in the adapter. I put the flare ring in the adapter before I applied the sealant and tightened it down. Then I connected that line set to the male flare of the adapter. Does that sound right? I could not find anything in the installation instructions about the small copper flare pieces but they seam like a crush ring.
Yes, it sounds correct, but we don't recommend using sealant. The flare connection is designed for dry connection.
@@CooperandHunterusa Thank you for the quick response. I agree on the sealant.
@@alittlebitofeverything5090 You're welcome! Let us know if you need anything else. Our Technical Support team is also available Mon-Fri 9am-5pm Eastern Time at (786) 953-6706
You can have a zones on a ducted unit with individual control ?? by using motorised valves. You never mentioned that in your discussion. Also these units are noisey.
Why does each lineset have to be a minimum of 10'?
Hi Bryan! 10 feet allows enough length for the liquid refrigerant to convert into its gas state.
What wil be happen if is less than 10 feet? Can be coil itifthe less than 10 feetin order to reach out the desire footage?
Your supposed to use a torque wrench when connecting the linesets.
Absolutely. Until you have at least 1,000 installations under your belt, a torque wrench is highly recommended.
I just wrench it. I put some Nylog and wrench it snug and then some.
@@md929 Everyone has their own methods ;)
Do all the rooms have to be in the same side of the house?
Hi Wandaly Torres! No, the rooms can be anywhere within the house, as long as they stay within the maximum line set distance from the outdoor unit.
This length varies based on the capacity of the mini splits. For example, an 18K Btu/h wall mount has a maximum line set length of 82 ft while, for a 36K or 48K Btu/h wall mount, it can be up to 115 ft.
@@CooperandHunterusa Is this length (82/115 ft) for each head/run? Or is it the total length for the whole system? Great info in the video, thanks!
@@RogerCoville Thanks Roger. Those are the max line set lengths per head.
If you do vacuum from the main Valve do you need to open all the individual lines ?o they stay close
Hi Roberto! Yes, you need to open all the valves that are connected to evaporators.
Cooper and Hunter , do you open the valves before or after you complete the vacuum?
@@robertosierra8078 You should open the individual lines first. Perform the vacuum. Then open the main valves.
I am close to purchasing this system off of Amazon. Is that the only place to purchase your mini split system? Also, when installing the line set for each head unit to the outdoor unit, does it matter which locations the 9000btu, 9000btu and 12000btu are connected to? I'm curious if for example A, B, or C are designed for the 12000 or 9000btu head units. Thanks in advance.
Our units can be purchased from a variety of online distributors as well as in HVAC supply stores throughout the US. You can check the LOCATOR on our website www.cooperandhunter.us
The connection sizes for line sets will depend on the indoor unit type. Be sure to check the specifications or double check with the seller for details.
@@CooperandHunterusa Thank you for the quick reply.
Did you have to evacuate each zone (low side) individually? So my question is after evacuating the first low side, you went to do that to each zone following before startup?
Great question, Matt! You can either vacuum each line individually or you can vacuum all of the lines simultaneously from the main valve. What's your preference?
@@CooperandHunterusa Your installation manual states "The outdoor unit does not need vacuuming. DO NOT open the outdoor unit's gas and liquid stop valves." This seems to contradict your above statement about being able to vacuum from the main valve. Or am I missing something?
@@inimic6900 Hi Inimic, sounds like you might be looking at a single zone manual. In this video, for the multi zone unit, we aren't vacuuming the outdoor unit, but we are vacuuming the line sets and indoor units. To be able to vacuum all zones simultaneously, you have to open the valves for each zone, but the main valve should be closed to hold the refrigerant in the outdoor unit. Alternatively, each zone could be vacuumed individually, in which case no valves would need to be opened.
I don't see a torque wrench.
Can i use another line to go more than 25' from the unit? Is there like an adapter?
We also offer a 50 ft option for line sets!
@@CooperandHunterusa What if we need to run roughly 85-90 ft.?
@@inimic6900 Sure, you can either weld the line sets together or use any line set adapter. Just remember that each unit is pre-charged for a specific line set length, so you will need to add refrigerant based on the final length of the line set.
Can I just call and get a tech guy to do all the installation fit me? Does your company provide that service?
Yes, David. We certainly recommend hiring a licensed HVAC technician to do the installation. In fact, it's required in order for your unit to qualify for warranty. We do not provide services - we are the brand. But any local HVAC service company should be able to help!
@@CooperandHunterusa thank you
Cooper and hunter, why didn't you look for supper heat?
Sorry, Martin. Not sure what your question is.
Are you referring to a Hyper Heat system? If so, the reason is because this family is located in Miami, Florida. So, they do not require a heating unit.
No torque wrench?? Torque values should be in the installation manual. Most mini split installations have refrigerant leaks due to this missed process.
36,000 BTU is how many HP?
36,000 BTU/h is about 14 HP
What the hell?? You cut and flared both ends?? Nice job of making work for yourself. You only need to cut and flare one end.
We don't mind going the extra mile to ensure a top-grade installation! :)
The fewer flares done in the field , the better.
@@CooperandHunterusa I don't buy it. What's the point of cutting off and flaring a factory-flared end? There is no point. You created work for yourself. Unnecessarily.
Your video totally glosses over the power line hook up. The units are not marked and your video is worthless. Is this a three wire 240V system or a 4 wire-ground, neutral, 120v and a second out of phase 120v line? Which terminals do you hook up to? The video doesn’t show. I have two Sophia multi zone inverters; a 12 and an 18.
To wire the unit, you need a 16/4 cable. The colors should match from the indoor to outdoor connection. All our multi zones are 230V, single phase. The wire joint shows 1, 2, 3, and ground. 1 is L1, 2 is L2, 3 is signal.
Sir you make video in hindi language
