Cost-Effective Climate Control for Medium-Sized Spaces
Skip the expensive contractor fees and take control of your home's climate. The MRCOOL DIY Select 12K 115V Mini Split offers a streamlined, budget-friendly way to bring powerful heating and cooling to rooms up to 550 square feet. Engineered with the everyday homeowner in mind, this ductless system features a pre-charged 11.5-foot Quick Connect® line set, completely removing the need for specialized HVAC tools, vacuum pumps, or refrigerant training.
Whether you are converting a standard garage into a workspace, regulating the temperature in a large master suite, or adding comfort to an open living room, this 12000 BTU DIY Mini Split Heat Pump delivers consistent, energy-efficient performance while running on a standard household 115V electrical circuit.
Match Your Aesthetic: Classic White or Modern Black
Your HVAC system shouldn't clash with your interior design. The MRCOOL DIY Select 12K is available in two distinct finishes, allowing you to choose the perfect look for your space. Keep in mind that the internal mechanics, capacity, and efficiency are exactly the same—only the exterior shell changes:
Traditional White Air Handler
The go-to option for a bright, clean appearance. It easily fades into the background of standard living rooms, kitchens, and bedrooms with light-colored walls.
Sleek Black Air Handler
A game-changer for modern design. The black unit adds a sophisticated, industrial edge that looks incredible in workshops, home gyms, media rooms, and contemporary office spaces.
The Advantage of the Pre-Charged Quick Connect® System
Many affordable mini splits on the market advertise themselves as "easy install," but leave out the fact that you still have to hire a technician to vacuum the lines and release the refrigerant to prevent system failure.
The DIY Select series eliminates that hidden cost. Thanks to the sealed, pre-charged Quick Connect® fittings, you can securely attach the included 11.5-foot line set to the indoor and outdoor units yourself. Furthermore, this specific 11.5-foot length minimizes left-over tubing, giving your exterior wall a much tidier, professional appearance compared to systems packaged with longer 16-foot or 25-foot lines.
Standout Features & Performance Benefits
- No Professional Required: Safely install it yourself using the factory pre-charged 11.5 ft Quick Connect® lines.
- Ideal for Mid-Sized Rooms: A robust 12,000 BTU capacity efficiently manages temperatures in areas up to 550 sq. ft.
- Convenient 115V Power: Avoid the hassle and expense of wiring a new 220V breaker—this system utilizes standard 115V electrical setups.
- Eco-Friendly Efficiency: Delivers up to 17.5 SEER2 for cooling and 9.0 HSPF2-4 for heating, utilizing the new R-454B refrigerant.
- Total Smart Control: Manage your room's climate from anywhere using the MRCOOL® Comfort App, or connect it to Amazon Alexa and Google Assistant for hands-free adjustments.
- Ultra-Quiet Operation: The indoor air handler runs as low as 17.5 dB(A), ensuring your sleep or work goes completely undisturbed.
- Built to Last: Features a Gold Fin® condenser coating to protect the outdoor unit against rust and harsh weather.
