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.

Mice ate all the wires in our current Mini-Split, and parts are impossible to find for some reason (AllStyles brand). Local AC/Heating guys will only install equipment purchased from them, about twice this price all in. Since I already have Electricity routed and holes in the wall, would this be a fairly easy DIY install?
"already have Electricity routed and holes in the wall"

this installation will be easier than waxing your car.

My point is that the system and instructions show using the included cable which is most likely STW cord.


The area around a condenser is must certainty subjected to damage so any conductors need to be protected. The PVC your referring to for the wall penetration is not an approved raceway for conductors.


I'm not referring to 240 volt runs inside a house. This is exterior and wall penetration. What voltage do you think the head unit uses? It can't be 120 volts for sure. Even if it was (which would require an additional neutral conductor to be run from the panel) the wiring still needs the same protection.


You cannot run NM cable in a wet location (outside) even if it's in conduit.
If your talking About power from the service disconneft, you use a piece of whip. Technically NM is not in a wet location if it is protected by a conduit.
Whips are usually water tight

Woops. I still may be wrong. Manual says position 1,2,3 are for the indoor unit. So no idea as to what the voltage is on this indoor unit.

Anways, reading the manual for Mr cool , you have to run your own power to it. The "included" cable is only to power the indoor unit, this is wrapped in a bundle with your refrigerant and drain lines and routed inside.

The only real issue I have with this is the lineset. If your at or about the length, that's great. But if your significantly shorter you have coils of copper sitting there, that can fill up over time with oil. Accumulation of oil in linesets aren't typically a problem (it works its way back) but when you have round coils of it, it is more likely to pool and settle down at the low spots.

Run conduit to cover the electric wires. No matter what you do, even you don't follow the code to add ac disconnect, adding shield to electric wire is bottom line to me.
I agree with you on this.. spent about a week researching the pros / cons and codes.. and came to the exact same conclusion.

The problem with it getting so cool so quick is it's not enough time to dehumidify the air. Overpowered systems can lead to mold problems.
I dont disagree with you.. My neighbor who is in the business brought that to my attention when I first got in (in the winter time).. But thankfully, here in Fla. we have had several mid 90 degree back to back days so far and my humidity is lower than usual, I have those cheap little govee temp gauges / humidity sensors throughout the house and it normally reads about 55 percent humid and here lately its been below 50.. So far so good.. Ive noticed this thing does leave a huge puddle in the back yard .. it appears to be doing a fantastic job pulling the moisture out..
I guess the true test will be in August Smilie

I tell you I truly could not be more amazed at the overall performance of these things.. by far one of the best purchases Ive ever made and I am that guy that is quick to have buyers remorse.

WOW. 50 percent seems high. Ours is usually less than 42 - 43 percent here in Florida. Anything higher and it feels sticky inside.

My mother's A/C system was oversized and did not remove the humidity very well. To combat this, I had it programmed to run the temp down to 68 once a day. That allowed the system to run longer and remove more of the humidity. Then the program would return to her preferred temp of (ISYN) 78.

How does the warranty work with this? I know you have to register the DIY product with Mr Cool within 60 days. If it breaks and it can be diagnosed over the phone do they just send you the part(s)? What about Costco's liberal return policy? Extra 24 month warranty if you use the Costco Citi card?

Not advocating doing anything unsafe but you should read wording of seller disclosure. At least where I live you certify that you are not aware of any issues. You are only liable if you are aware of something and don't report it on the seller disclosure. Like presence of lead paint for example. Person bringing lawsuit has to prove that you knew there was an issue. So say you were certified electrician and ran Romex outside but didn't report in seller disclosure. This would be actionable if something adverse were to happen. But they would have to prove it was you who ran the cable. If you had no knowledge of it you can't be liable.

Costco also carried the 12k DIY for $1099, but not currently on their site. It's a great unit if available. Runs off of 115VAC.
Wow nice I will check that out.
My only issue with Mr. Cools are that horrible outside ducting ... I have a mitsu and its nice heavy straight tube Gutter style plastic but Mr. Cool looks cheapy from pictures. Insight?

Dam i need the 18k unit. Just getting one for my 300sq foot sunroom.

Where are you getting your "technical" knowledge? Do you feel your reasoning is superior to those highly educated professionals who have been writing the code for decades? You simply do not understand about electrical conductors, conduit and the reasons for the codes. ANY wiring in an outdoor location is considered to be in a wet location even if it's in conduit, including a whip. NM cannot be run in a wet location because it's not rated as such. Please stop spreading false information.

Thanks.
