Affordable DIY Comfort Without the Installation Cost
Transform the comfort of your space without the high cost of professional contractor installation. The MRCOOL DIY Select 9K 115V Mini Split delivers reliable, energy-efficient heating and cooling for rooms up to 400 square feet. Built on proven MRCOOL® technology, this system simplifies installation with an included 11.5 ft pre-charged Quick Connect® line set—meaning you can install it yourself without vacuum pumps, gauges, brazing, or specialized refrigerant handling.
Whether you are upgrading a bedroom, finishing a garage, or cooling a home office, this highly efficient 9000 BTU DIY Mini Split Heat Pump offers smart control, whisper-quiet operation, and next-generation R-454B refrigerant.
Choose Your Style: Standard White or Sleek Black
The MRCOOL DIY Select 9K allows you to match your HVAC system to your interior design. Under the hood, these are the exact same high-performance systems. The only difference is the finish of the indoor unit:
Classic White Air Handler
The standard choice for a clean, unobtrusive look that blends seamlessly into traditional home interiors, living rooms, and bedrooms.
Modern Black Air Handler
Finally, a mini split that doesn't look like an appliance from a beige office building. The sleek black option provides a sharp, modern aesthetic perfect for design-focused spaces, man caves, workshops, media rooms, and modern home offices.
What Makes the MRCOOL DIY Select Different?
Many "budget" mini splits claim to be DIY-friendly but still require you to hire a professional to evacuate the lines and handle the refrigerant. If you skip those steps, the system's lifespan and performance suffer.
The DIY Select series solves this problem. It utilizes factory pre-charged Quick Connect® fittings. You simply mount the indoor unit, connect the pre-charged line set, plug it into your 115V power source, and turn it on. The shorter 11.5 ft line set (compared to standard 16 ft or 25 ft sets) also means less coiled, excess tubing on your exterior wall, resulting in a much cleaner, professional-looking finish.

Do I need to hire a professional to install the MRCOOL DIY Select 9K?
No. The MRCOOL DIY Select series is designed specifically for homeowner installation. Because it includes an 11.5 ft pre-charged Quick Connect® line set with sealed fittings, you do not need to use a vacuum pump, gauges, or handle the refrigerant yourself.
What is the difference between the white and black air handlers?
The difference is entirely visual. Both the white and black models share the exact same internal components, performance ratings, 115V power requirements, and 9,000 BTU capacity. You are simply choosing the color that best fits your room's aesthetic.
How large of a room can this 9,000 BTU system cool or heat?
The 9K DIY Select system provides enough capacity to comfortably heat and cool spaces up to 400 square feet, making it an excellent choice for bedrooms, home offices, small garages, and enclosed sunrooms.
Can I control the mini split with my smartphone?
Yes. The system connects to Wi-Fi and can be controlled using the free MRCOOL® Comfort App. You can easily adjust temperatures, switch between heating and cooling modes, and set daily schedules from your phone. It is also compatible with voice commands via Amazon Alexa and Google Assistant.
