My home is about 1300... I have a nice carrier hvac system that never cooled down the master bedroom or the add on 20 by 20 den.. I live in Florida..
I bought the 12k for the master bedroom and was so extremely impressed with how freezing ice cold it would chill the room in a matter of minutes..
It chilled it so nicely that I could tell the whole back of the house was colder when I had it on..
So I went ahead and bought the 24k for the den... Same results.. It not only blows ice cold it cooled the entire den down in just a few minutes..
I quickly realized that just running the 12k in the bedroom and the 24k in the den completely eliminated my need to ever turn on my HVAC again..
It cools the entire house down in minutes on a very hot day.. The HVAC system would run all day to barely maintain the chill in the house on a 90 degree day..
These 2 units are miracle for me.. They run at half the power and only a fraction of the time.. I predict these things will put hvac ducted systems out of business in the near future..
I was able to install both of them myself .. Purchased romex, breaker , and cut off box from amazon , ran the wires to the panel.. I had never done it before but after a few youtube videos and my desire to save a few hundred dollars the install was flawless.. I also purchased a 3 inch hole saw for my cinder block walls..
all that being said.. I dont think you will need the dual zone units if you do what i did.. place a 12k on one end of the house and a 24k on the other you will be amazed.. - oh and this is a very good deal.. i paid 1650 for my 24k from ingrams air and water.

Never even heard of that brand. Mr Cool has been making these mini spit systems for quite a while. And I'm also seeing 17 seer on HD's site [homedepot.com] as well. And like the other guy was saying above, it probably isn't a true DIY type system either. Looks like it has the flare ends on the line sets already (which is good for a DIYer because you need a special tool for that plus it's something easy to screw up if you don't know exactly what you're doing), but are they sealed from the factory like the mr cool ones where the line sets are punctured when you attach them? If not, it really should be evacuated/checked for leaks before starting up. Now this can be done with a gauge set and a vacuum pump but that's going to add to the cost a bit. Planning on having somebody come and do it... well you're already over the price of the mr cool system at that point and the discussion is over.

I usually get a bunch of years out of window units (have to handle them carefully and clean them well with bleach or whatever to get the mildew out of them at the end of the summer before you put them away). I'll tell you what I've had fail a in them a few times now, the motor bearings. I'm not going to lie and say it's super easy to replace them but if you have a little patients and a couple hours of time then they can be replaced. They just take small sealed bearings just like the ones found in skateboard or rollerblade wheels. First time I needed some I got them locally at a ACE or something and they were kind of expensive and the following time I ordered them from Amazon [amazon.com]. Not saying that they're all the same size but so far I replaced the ones in an LG and a couple of GE window units. Believe the blower motor was frigidaire in them if I'm not mistaken. Wonder how many good window units get tossed into dumpsters every year because two one dollar bearings go bad LOL.

This is virtually the same argument to get an AUX unit. For the price of mr cool you can get almost 2 aux units.

I do not know how you do not need to pull a vacuum, but I've never done a mr cool either. But you always have to pull a vac- unless maybe the lines are pre-vacuumed (doubt it) and it has some sort of valve to open the vacuum and then you use the refrigerant to break the vacuum, then purge...
Everything is pre-charged with pierce connections and two capped valves on the compressor side that you open once the high and low pressure connections are made. I suppose if you played around, you could lose an ounce or two, but not normally. Most all DIY systems, including A coils and lines have been this way for a long time.

Quote from httyuwma :
These type of units use a rubber cord between the outside and inside unit. You cannot legally use the supplied cord as most videos and the manufacturer instructions show. These rubber cords carry 240volts and are not allowed to be run along, inside, or through walls. The only way I see to install these per code is by running conduit between the units to protect the wiring.

What this means is that if there's a fire, or someone gets hurt, by an installation that was not up to code and/or permitted by your city then your insurance may not protect you. Additionally it may not pass inspection when you sell the house.

Please check with your city about what they require before putting your property and others at risk.
Correct me if Im wrong, you can run UF externally, along side a wall, as long as it isnt in a position where it can be physically damaged. You can run most definately run it between the units, as you do not simply run wiring through a hole , you actually install a piece of PVC piping (which acts like a conduit). The head unit does not require 240V.

The problem Im having with your statement is that 240 is run all the time inside the house. If your running straight lines, then yes, it must be in some sort of conduit. However NM cable is acceptable, so is BX. Depending on your location NM may need to be in conduit if exposed even on the inside, if subject to damage. But you can run NM freely in most parts of the country in wall.

External power runs need to be in conduit- but not UF. (see above).

Assuming an external run of 240, only the outside condenser is getting 240- the head unit does not receive 240v power. 120 from the condenser goes to the head unit. So technically you are not running 240V through the wall at the point of this unit.

Assuming an internal run of 240, you would normally turn it around and make an external shut off box- run a whip to the conndenser.

Quote from missmatch :
Now a mini-split like this hooked up to some solar panels would be the perfect daytime summer setup; When the sun comes up and the PV solar cells start producing electricity, once it reaches a certain threshold, something clicks ( I believe that would be called a capacitor) and the AC starts; At dusk, when the current produced by the PV cells falls below a certain threshold, the same think clicks again and the AC unit shuts off!
They actually make one. DC hybrid inverter mini split. Require I think 3 250w panels at a minimum, but they can use partial solar, all solar and some models can use batteries as well. Does exactly what you ask (sun comes out, it turns on. Sun goes away it turns off. If your shy 100w, it will draw 100w from the grid. If your shy 200w, it will draw 200W., etc)

I had to edit this. You are correct, it appears the MR cool units use some sort of tapping ring, so I assume the lineset is pre-evacuated. The manual makes no mention of pulling a vacuum.

Anyone use one of these in a garage? Wouldn't want to run it 24x7 but would like to turn it on when I'm working in the garage. I'm in the south so the garage will get pretty toasty.
Yes I have it in the garage.

I did add extra insulation to my garage doors. We are about 2 hours south of Canada.

It keeps the 900 sq feet as warm or cold as I want.

Allegedly, these variable speed units usually provide their best effiencies by runnin at one temp all the time. That said, if your only working in the garage once every week, that probably doesnt apply.

This good for a 2 car garage to cool?
I installed this unit 2 years ago for my 4 car garage. It's great and cools nicely. My walls and doors are all insulated which helps a ton.

Someone else made a comment about running 12kw units on 120v. If they do make one I don't recommend it. the largest you should go on 120v is 11500. You can however find wall units that are inverter based.

Any suggestions for a regular 115v A/C unit? Really does not want to run a 220v line - just want to plug it in a switch in the attic.
The mini-split condenser cannot go to the attic. It will probably overheat. It is meant to go outside of your house and is supposed to connect to a dedicated Disconnect.

The difference between 20-25 is marginal in your acutal savings. its huge between 10-20, but marginal from 20-25; its added expenses are nearly double to triple however. These are all coming with 410a, which will probably be phased out by 2022. Just look at the cost of r22 today,. They were still building and installing those in 2007. Considering the cost of r22, it is actually cheaper to just switch to a *newer* mini split when the time comes.
.

Will 410a be phased out [refrigeranthq.com]? .... an interesting read.

Only if Honeywell and Chemours, that already owns the EPA, buys the right judges off to profit from their ventured monopoly that shuts everyone else out.

410a does not contain any chlorine and is exempt from the Clean Air Act and EPA enforcement.

Meanwhile, millions of pounds of R22 was hoarded and still being sold at about $9lb wholesale and $20 or so retail. Heck, I came across some R12 the other day.

That is cool.... like the similar ComfortStar, I am rather certain the lines are connected to the evaporator and also freon charged. I don't know that the condenser, even with an expansion tank could hold enough to charge 25 feet of line and the inside unit.

That's actually a drop in replacement. Not actual r22

Air Conditioner and Heat Pump, so yes, it does heat also.
If you see a unit that does not mention, Heat Pump, then it cools only
