Overview

Looking for a mini split ductless HVAC system you can install yourself? The 3rd Generation MrCool DIY 18k BTU 20 SEER Ductless Heat Pump Mini Split System is the answer. You won't need any special training, tools, or equipment to set up this split system. It's a powerful mini split with a capacity of up to 18,000 BTU and can heat a space up to 750 square feet.

How simple is installation really? Crazy simple with the pre-charged Quick Connect line set, MrCool's cutting-edge technology that makes installation cost efficient, safe, and simple. And don't worry about space. The outdoor heat pump has many different installation location options. This option is a slim alternative at just 34 inches wide, 28 inches tall, and 15 inches deep, and it can be anchored to the ground or attached to a wall with a bracket. The indoor air handler is mounted to the wall and can seamlessly fit into your home to keep you comfortable year round.

The 3rd Generation MrCool DIY 18k BTU 20 SEER Ductless Heat Pump Mini Split System can operate in the winter in single digit temperatures, as low as 5°F, and its heating range indoors is from 32°F to 86°F. In the summer, keep your home cool to your liking with a cooling range of 63°F to 90°F. With this HVAC solution, you can stay comfortable year-round.

If you live on the coast and are concerned about salt water damaging your unit, the 3rd Generation MrCool DIY mini split comes with a Gold Fin Condenser that is built to withstand long-term exposure to salt in the air and resists corrosion. 3rd Generation MrCool DIY 18k BTU 20 SEER Ductless Heat Pump Mini Split System condensers are built to last with materials aimed at reducing repair calls.

The refrigerant in this 3rd Generation MrCool DIY mini split is R-410A, a more environmentally friendly option to the standard Freon. R410A is chlorine free and doesn't damage the ozone layer.

With MrCool, interruptions to your daily life are kept to a minimum. You can trust that your unit will run quietly and smoothly while it manages your home's temperature. The 3rd Generation MrCool DIY 18k BTU 20 SEER Ductless Heat Pump Mini Split System features an automatic horizontal louver. Set the louver so your home is evenly cooled or heated and the wall unit will automatically return it to that position once it begins its operation. Plus, in the event of a power outage, this mini split also automatically restarts as soon as power is restored, cooling or heating your home as quickly as possible.

The indoor air handler of this mini split system offers several modes so your HVAC can work according to your preferences. In AUTO mode, set a temperature and the unit will choose cooling, heating, or fan only based on the temperature in your room. In SLEEP mode, save money while you sleep as the MrCool reduces energy use through the night. You can also limit your energy use with the TIMER feature, which sets a timer for your heat or air conditioning.

The air handler features an Anti-Mildew Function that runs a low fan for 10 minutes after cutting off to dry out your unit. With this option, you can trust the air you breathe is clean and fresh.

The 3rd Generation MrCool DIY 18k BTU 20 SEER Ductless Heat Pump Mini Split System is smart and can be controlled wirelessly with the included remote, Google Assistant, Amazon Alexa, or from an app on your Apple or Android smartphone.

Q & A

Do you have questions about this product?

Sort by ASC
Can the MrCool DIY be ordered with a shorter line set?
What does it need for electrical connections
I’m doing a new construction man cave and haven’t run the wire for heating yet. What size wire do I need for the 18k unit? The room is 640 sf.
What is the difference between 16 and 20 seer units?
What size breaker does this require
The installation manual states not to install in areas of prolonged sun. I need to install on the south side of my house( south central Kentucky), how would I be able to protect the outside unit? Thanks
can I order a shorter lineset? 15 feet or ????
How close to the ceiling can this be mounted. The only spot I can put the unit is above a sliding door.
In all of the videos that I have watched, the inside unit was high on the wall and the outside unit was on the ground. My installation will be the opposite. My outside unit will be on the roof, quite a bit higher than the inside unit. Is this going to make any difference?
I would like to substitute a 16' line set for the included 25' set. I presume this is possible? Thanks, Guy
do you have lineset covers in stock? I just bought a MRCOOL 18K mini split and looking to buy the cover. Site mentions it is out of stock. Do i really need 4.5 inch? I have seen 4 inch covers on amazon. I don't want to force fit it in thought.

Thanks

R/ Mike
I want to mount the air handler on the front wall of my house. Can i pipe the line set out the side of the unit instead of directly out the back?
Hi ,the electricity I have is 208/230 volt and McCool unit is 240 volt , Can I get any problems with the electricity if I do the connection? Or it will be okay
What is the shipping cost to Florence MS 39073?
Can unit be ordered with a shorter line set.
Interested in 18K DIY Spit Ductless sys with 16' lines.
Is that available? OR...
Do I have to order the unit with 25' lines (throw them away) and order a separate 16' line set?
Since this bundle comes with a 25' lineset, can a 16' lineset be purchased separately and the 25' one included re-used for a different DIY set (combined with the required coupler?) Or does it come pre-connected in any way that would force it to be used with this bundle/kit.
Can I order this with the shorter line set?
Is everything included for install?
Is this Item in stock and how long does it take to be delivered :
Mr.cool diy 3rd generation 18000 btu spilt unit
Thank you for your assistance
Joe varro
Does it require 220v 3 prong or 4 prong plug and receptacle?
How long is the line that connects the outside unit to the inside air handler for this DIY Mini split ductless heat pump?
I live in Louisville KY where winters can be as low as 20 deg one year and then next year it could get as low as below zero. This states good for 5 deg. Will this still work in my state if temperatures did get below 5 deg, what happens when temperatures are below the 5 degrees?
This unit comes pre-charged? So no HVAC Tech needed to pull a vacuum on lines and put a charge in?
Do you sell the wall hanger support for the external Mr Cool unit (18000 BTU)
Hi , I will like to know the measurements of the inside unit please
I have a room about 400 sq. foot, would the 12 seer work or would it be better to get the 18 seer?? it would be installed in a bonus room in north Georgia . it will be well insulated. thanks
How noisy is it? Can I put the outside unit in the garage on the wall?
How long is the line set that comes with this unit?
The MR Cool web site lists the 3rd gen DIY mini splits as available with 16’ or 25’ linesets (precharged). Your web site says only 25’... Are you up to date with this information??
Is this unit in YOUR stock? The reason I ask is, I ordered this unit from Lowe's, said it was in stock. Ordered on Jun 12th and it just arrived today, jul 7th. Come to find out it was a special from Mr Cool and they are in a three week back log.

I'm thinking of ordering another unit.

Thank you


Can complete unit be mounted indoors?
Can you order longer Freon hoses?
Can a condensate pump be used with this model?
Does this include the air conditioning?
Do you have any units for more than one room?
Although it's been previously asked, I would like to verify the indoor 18K unit dimensions as there appears to be conflicting information. The model line customer brochure states the 18K and 24K units are identical (42.52x8.90x13.19). While page 17 of the installation manual does have these dimensions for the 24K unit (in the schematic of the mounting plate). The dimensions for the 18K are listed as 38.0x?x12.55. My question is which is the correct dimensions? If the installation manual is correct, what is the depth of the unit? Thank you ahead of time.
What are the measurements for attaching the 18K and 24K outside units to a concrete pad. Want to pour before I order. Would be nice to be able to preview installation instructions like some other brands I have looked at.
can you getg this is 115v?
I live in Austin Texas and am looking to put a mini split in my garage to cool it down, since my wife uses it for a workshop.
Would the 18BTU McCool system be sufficient for this job? Dimensions: 25X22X8 and my house faces NE putting the garage at the NE corner.
Thanks for your help.
What do you do with the excess length of a line set?
Can the line go up 3 ft into attic then back to ground level on Mr Cool DIY system?
