MRCOOL(R) DIY(R) Mini-Split is Truly Do-It-Yourself: Innovative Company Has Only HVAC System That Homeowners Can Install

HICKORY, KY, KY / ACCESS Newswire / October 14, 2025 / MRCOOL®, a leading innovator in residential and light commercial HVAC solutions, proudly announces that its patented Quick Connect® pre-charged line sets make the MRCOOL® DIY® Ductless Mini Split System the only HVAC system on the market that homeowners can install themselves, as it does not require specialized refrigerant handling.

Unlike conventional mini-split systems, which require a professional installer to charge, evacuate, and adjust refrigerant lines, the MRCOOL® DIY® Ductless Mini Split system uses factory-sealed, pre-charged copper line sets with patented, Intertek-tested, Quick Connect® fittings that maintain system integrity and ensure zero refrigerant exposure if handled with care. This design doesn't just help homeowners by allowing them to install their own HVAC, it enables contractors to perform even faster installations, making more time for more jobs.

Because the MRCOOL® DIY® is the only HVAC system on the market with the patented technology to facilitate a novice installation, competitors have taken note. "A motivated homeowner will take on nearly any project," said Bonnie Clymer, Chief Marketing Officer. "With our MRCOOL® DIY® system, capable people have a safe solution for heating and cooling. Unlike competitor products that require steps only licensed professionals can perform, MRCOOL® DIY® is designed for straightforward installation without compromising safety or compliance."

The Quick Connect® design and installation method are protected by a portfolio of patents, which grant MRCOOL® the distinction of being the sole HVAC brand that has the right to offer a do-it-yourself installation method. Because of this, no expensive, specialized tools or training is necessary to install the system.
The system's Quick Connect® fittings have also been independently tested and verified by Intertek, a global leader in safety and quality assurance, as well as other third-party companies to guarantee product excellence.
When it comes to quality in design, testing, and performance, MRCOOL® exceeds expectations.

"Since our founding in 2014, MRCOOL® has always stood for innovation that makes comfort simple," said Jason Ingram, Managing Member at MRCOOL®. "Our DIY® system and patented Quick Connect® line sets empower homeowners to safely, and affordably, install professional-grade heating and cooling without specialized tools. From the moment it was released, it was and continues to be a game-changer for the HVAC industry."
