Whether you’re fine-tuning a home office or finally reclaiming your garage, true comfort should adapt to you, not the other way around. You shouldn’t have to choose between a professional-grade climate and a budget-friendly price tag.
As the newest addition to the MRCOOL® DIY® lineup, the DIY® Select is designed to make high-quality, ductless comfort more accessible than ever.
A Smarter Entry Point into DIY Comfort
The DIY® Select is one of three new do-it-yourself systems, and it’s built specifically for budget-conscious homeowners who still expect reliable performance. By combining proven technology with streamlined features, this system delivers dependable heating and cooling at a price point that opens the door for more people to go ductless.
With efficiency ratings up to 17.5 SEER2 and 9.0 HSPF2-4, the DIY® Select proves that affordability doesn’t mean compromise.
Available in 9k, 12k, 18k, and 24k BTU sizes, it’s easy to find the right fit for your space no matter the application.

Control is just as flexible as the design. You can adjust settings instantly with the included wireless remote or manage everything from your smartphone using the MRCOOL® Comfort App.
From temperature adjustments to scheduling and energy monitoring, full system control is always within reach.
With the app, you can:
