Overview

Take full control of your home comfort with the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System. Homeowners can easily install this outdoor heat pump condenser and indoor air handler since installation requires no special tools, equipment, or training. This full heating and cooling system can be installed in just a few hours. It has a heating capacity up to 12k BTU, so it is ideal for spaces up to 500 square feet depending on your climate zone.

The key to the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System's easy installation capability is the pre-charged Quick Connect line set — MrCool's cutting-edge technology that makes setup safe, simple, and cost effective. The line set uses the environmentally friendly, and chlorine-free refrigerant R-410A, which is an alternative to old refrigerant that won't damage the ozone layer.

But what if your new MrCool ductless mini split runs low on that same R-410A refrigerant? Not to worry, since an alert will appear on your indoor unit. It lets you know so you can address issues before they cause costly damage. Should a power outage occur, the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System will auto start once power returns, making your home comfortable as soon as possible.

That's not all. The MrCool indoor wall unit also displays alerts when the air handler filter needs cleaning or replacement. With this feature, you can trust the air you breathe is always fresh! The cleaning alert displays after 240 hours of operation and filter replacement is suggested after nearly 3,000 hours of run time.

The outdoor MrCool mini split condenser can be anchored to the ground or attached to a wall with a bracket. The outdoor unit is 31.5 inches wide, 21.8 inches tall, and 13.1 inches deep, while the mounting dimensions are 20.24 inches wide by 13.39 inches deep.

The 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System can handle a wide range of outdoor temperatures, as low as 5°F and as high as 122°F. Plus, with the auto, sleep, and timer modes you can customize your system to run to your preferences and keep your HVAC running efficiently; saving money.

When the 3rd Generation MrCool DIY mini split is in COOL, DRY, or AUTO mode, an anti-mildew function activates and keeps a low fan running for about 10 minutes with low airflow to dry up condensation that can cause mildew growth. The unit also runs quietly and smoothly so you can trust it will work without any noisy interruptions while it keeps your air clean and at just the right temperature.

Want exacting control? You can control the 3rd Generation MrCool DIY 12k BTU 22 SEER Ductless Heat Pump Mini Split System wirelessly with the included remote, Google Assistant, Amazon Alexa, or an app from your Apple or Android device. Get custom performance from your ductless MrCool mini split system with the FOLLOW ME feature, an option for your maximum comfort that will track the air temperature around you as long as you keep the remote nearby.

Is it ok to run the line set in the attic so I can hang the air handler on a inner wall?
Is the refrigerant in the line set or in the condenser? 25' is too long. I need about 10' +/- so will need to cut the line set. Can I do this?
Can a hvac man do it if I can't?
Thanks!
How do I order a 16’ line set for the 12k btu 22 seer McCool diy? And can I order it when I order the unit instead of the 25’ at the same price?
MODELS: DIY-12-HP-C-115B, DIY-12-HP-WMAH-115B
I have an older house that has 60amp fuses in the breaker box. It is 120 V. I was wondering how much amperage these units would require?
Can the indoor unit be installed with the line set coming off the back left side of the unit instead of the right side?
Can a 2nd air handler be added to the condenser?
I want to add this to my wine cellar, would it work for those temps and humidity?

Mark
what is lowest ambient temperature this will heat in? thx
I am in the rough electrical stage of a room addition right now, and want to add another Mr. Cool to my inventory. I have 2 others and think they are great. I will, most likely, not be installing the unit until the late Fall, but want to purchase the unit now, to make sure that everything is "in order" when the framing and electrical is done. Since I will be installing the unit on an inside wall, I have the ideal location for the moisture drain. Any hints about running the drain line into a drain vent? When will my warranty begin, when I buy the unit, or when I finally do install it?
I do not want the WiFi feature, keeping it simple and I really do not think I will want it. Can I purchase the unit without?
Mr. Cool really does need to offer units with shorter line-sets for installations directly outside of the air handler. Coiling the extra line-set up behind the outside unit is unsightly & minimizes airflow. My only complaints.
Can you get a longer line set if needed?
I understand that the 12k mr cool diy mini split has a shorter line set out now. Is this true and if so, how long is it and do you stock it? Thanks, David
WHAT else will I need to buy? a quick disconnect for electric? Line set cover what else?
I will be using this in a 350 sq ft. outbuilding is the 12k to big
How much clearance from the house does the outside unit require?
And another one. What is the size, thickness and strength of the concrete pad that is required to place the outdoor unit on? We do not have an available concrete pad to place the outdoor unit.

Thanks again!
Is there a 12K unit (DIY) that has a ceiling cassette, instead of the wall mounted air handler unit?
how long are the blow unit lines? with the lines attached gives you an extra 2' (estimated) on top of the 25' lines?
Is the wire for the electrical connection for the house included in this bundle for the DIY user?
does the 115v system cool as well as the 230v
Is it possible to get the unit with a shorter line set up? I don't need 25' of line and don't want excess line just hanging on the wall next to the unit.
I'm considering the 12K DIY Mr Cool system. Does this unit have a "Dry Mode" to control humidity with slower fan speeds? Thanks.
According to what Ive seen on your site. I can elect to get a shorter 16 foot line set? Correct?
Is the room temperature sensor in the remote control? Or in the air handler? Thanks
when do you anticipate theMODELS: DIY-12-HP-C-115B, DIY-12-HP-WMAH-115Bbeing back in stock?
What kind of electrical outlet does the DIY 3rd Gen use?
Is it just wires that you need to connect to an electrical whip and then to a standard 120v 3-prong outlet, but on it's own breaker? Or is it like a 30A RV type plug? Or is it not even a plug in thing and it has to be wired directly to an electrical box on the side of the house? I'm wanting to wire it to my enclosed trailer, so I can connect it easily to either my house, or to my generator, but not understanding what the plug requirements are? (I would have an electrician install, but don't understand what to tell them on what I need). Thank you.
If I have some electronic equipment closer than the 1 Meter distance as given in the specs, what effect will the electronic equipment have on the WMAH? and what effect will the WMAH have on the electronic equipment? In other words, what interference can we expect from this unit and how does it manifest itself? i.e. static in the electronic equipment, and/or interference with the WMAH's electronic controls and or the remote unit?
Any ideas? Thanks. Also, what is the cost of a pump incase the water needs to be pumped out of the drain line?
After reading over the warranty, it appears to be protected, it must be installed by a licensed HVAC person? Is this correct? If so, why would I pay the extra cost for a DIY unit?
Do they make a shorter line set?
how many sq ft will the HA20868 do
can i just get the copper coil protector separately if so where and at what cost/?
How many watts or amps does the unit consume?
Could Item#HA20868 be ordered with the 16ft. Line set?(Mr. Cool 12Kbtu, 22 SEER DYI mini split bundle), I’m not shopping I’m looking to order thank you.
Are the DIY units hard wired or do they plug to an outlet? Also does the air flow come from the bottom of the unit? What size unit is recommended for a 240 sq foot space.

Thanks.
Is it possible to route the line set to the left side of the indoor unit instead of the right?
What is the length of the line set?
installing unit on inside first floor wall. line set will run down wall into basement then to outside wall to condenser. drain line will terminate in house plumbing. can you offer any suggestions or pitfalls i may encounter.
Is this unit compatible to a hard-wired thermostat?
Can the wall mounted unit be installed in a window well used for a standard basement window? We currently have an AC unit installed in the window well and mounted in a wood frame to help seal out outside air. If so, could the piping coming out the back of the unit come up through the window well and tie in to the outdoor unit?
One more question. If I can mount the indoor unit in place of an AC unit in a window well, it will be mounted to a framed "wall" in place of the normal window, would I be able to drain the unit into the window well? I envision the AC hoses, electrical, and the water drain will be coming through a hole in the "wall" and that the drain hose could then be cut and allowed to drip into the window well. We live in a dry climate (Denver) and humidity is usually low. The bottom of the window well is about a foot below the bottom of the framed window opening. If this can be done, then I would save the cost of the pump in the outdoor unit. What is the cost of this pump, if it is found necessary to use it? Thanks for all your help!
Is this unit 220V?
can you also reference the appropriate line cover for exterior wall, and 6' power whip.... or should I get that at local hardware store?
We are thinking about buying an oversized DIY unit for our basement studio. It is 480 SF, requiring only a 12K, 1 ton unit. The oversized unit would be a 24K, 2 ton Unit. If we install a either unit in our house, will we be able to remove it and re-install it in another house in the future, say 2-3 years hence? Also, can we retrofit a larger unit for dual zone use in the future, with a valve system and additional electrical connectors for a possible two room installation?

Thanks
What size are the electrical holes on the side of the condenser unit? Will they fit 1/2" or 3/4" Conduit connectors?
What DIY multi-zone heat pump configuration would be recommended for a home with two rooms needing service: the first room is 1095 square feet and the second is 500 square feet. The first room needs a 16 foot line set and the second room needs a 25 foot line set. Thanks!
Is it possible to get a longer line set then the 25' one ? Like 50' line set for the DIY 12k?
What is the sound rating of the indoor unit?
How loud is it inside? Db
I need to route the lines out through the side of the unit rather than through the back. Given the configuration of my room and windows, I don't have enough ceiling clearance to route the lines outside near the top of the wall without angling the drain line upward. Is it ok to route the lines down toward the floor, inside the room, and then out through the wall near the floor? I understand that I'll need to cover the lines to be reasonably aesthetic.
What is the sharpest bend one can make in the copper lines, in terms of radius of the bend and what tool would one use to bend the lines? We are looking at a finished Basement install. Also, can the WMAH unit be mounted on a wood frame and offset from a wall so that the Line Set can go straight up to a suspended ceiling, then curving to go over the concrete foundation and sole plate and exit the house above the foundation, rather than through a window opening?

Please advise. Thanks!
What is the electrical requirement for the mr. cool 12,000 a.c. Amps, dedicated breaker,etc.? thank you
How can I tell which systems include a base pan heater?
My room is 600 sq ft. Is the 12k sufficient or do I need to move up to the 18k.
Will you soon in the future offer the 12K heat pump DYI with the option of a 16’ line rather than the 25’ line. For me I only need about 10’. Thanks!
Do you have any active discount codes?
Is this unit in stock?
Can it be winterized during the winter? Or do you have to have a cover to protect it from the cold?
What kind of savings in utility costs can we expect? We currently are paying $.14 per kwh of electricity and averaging 800 kwh per month or 9600 kwh per year.
Hi I have ordered this system and i read the online installation manual and i just want to verify that it requires no. 10 AWG wire so i can run it before the unit gets here. thanks Dana
can I get 10 foot line set
I need a multi units 5 units
Where would this ship from? ETA on arrival to 85323 zip code? Is expedited shipping available? If so, at what cost?
Mr Cool referred me to you telling me you sell a coupler that will connect their line-sets together to get a total longer length. Where do I find the one for the 12K DIY Mr Cool unit to connect two 25-ft line-sets together? Also, how many line-sets can you connect together to get longer length?

Thank you.

I live in boston, and plan to heat more than cool. Will I need to mount the outdoor unit on the ground or elevated off the ground? Your video of the defrost cycle seemed to imply that the unit should be above ground. Will the defrost water drain properly if the outdoor unit is on the ground?
I have a gas hydronic boiler, 78% efficient. Electric rates here are $.23/kWh. Would using the heat pump save any money?
Thank you!
