The Mrcool mini split ductless air conditioner would make a great choice, as it’s got a decent SEER rating of 22, and features technology that doesn’t eat too much into your energy costs. If you’re shopping around for the best ductless mini split air conditioner, then the DIY-12-HP-115B25 Mrcool mini split AC unit should be among your top considerations. Get through to the end of this review to find out what it’s capable of doing for you.

Why We Like It – Mrcool Mini Split

The Mrcool Mini Split air conditioner is a great option to consider especially if you’ve got spaces that average around 500 square feet in size. With a 12000 BTU rating, the AC unit is sufficiently powerful to cool down the average living room space, and since it also features a heat pump, you will be able to use it to warm up the air whenever it’s too cold.

  • Supports use of Amazon Alexa & Google Assistant
  • High SEER rating of 22
  • 7 Year Warranty on Compressor & 5 Year Warranty on Parts
  • Quite expensive


Each indoor unit in the Mrcool ductless mini split air conditioner is capable of cooling a room that’s as large as 500 square feet, and this is thanks to its 12000 BTU rating. This makes it significantly more powerful than the SENL-09CD Senville mini split air conditioner, but they both rely on inverter technology, and this makes them efficient in how they function.

Energy Efficiency

The Mrcool mini split air conditioner is very much energy efficient. It’s got an SEER rating of 22, (making it better than the WYSO 12A-19 Pioneer Mini Split which has a rating of 19) and if you’ve never heard of an SEER rating before, this is basically a measure of the air conditioner’s efficiency in a year, and it gives you an indication of how expensive it is to maintain. Any rating that’s above 13 is considered to be good, and any over 20 is considered great.


As with most modern air conditioners, the filters on the Mrcool mini split air conditioner are removable, and also easy to wash. The recommended period for replacing filters is every 2 to 3 months, and this is important to take note of because it affects the quality of air conditioning. The filters trap any foreign elements in the air, and also improve its odour.


The 5 year parts, 7 year compressor and 1 year remote control warranty policy that comes with the Mrcool Mini Split is impressive, but it doesn’t match the one you’ll get with the Daikin 12000 btu mini split air conditioner. Daikin offers a 10 year parts warranty and another 10 year replacement compressor warranty, making it slightly more viable than the Mrcool AC in terms of longevity.


For added convenience and easier operation, this Mrcool air conditioner comes with support for use with both Amazon Alexa and Google Assistant out of the box, so if you don’t have it’s remote control nearby, you’ll still be able to use your phone or your voice to change the settings on it.

Mrcool Mini Split Wrap Up

As a company that was established in 2014, Mr cool still remains a new entrant to the air conditioning space, but for the few years that it has been around, it’s gained a lot of popularity for the quality of its products. The DIY-12-HP-115B25 DIY is just one of their many mini splits that have gone on to gain a lot of popularity among buyers, and if you have a look at it’s Amazon page, there are a lot of positive comments about it that people have been able to leave.
