MRCOOL Heating and Cooling Solutions is the cutting edge of what modern, flexible fabrication can produce. These systems rely on state-of-the-art manufacturing processes and advanced design to deliver high-efficiency air comfort anywhere you need.

And so we innovate and grow; we innovated Do-It-Yourself for heating and cooling. MRCOOL DIY ductless mini-splits are the only actual DIY HVAC on the market, with three different ways to install it, including No-Vac® Quick Connect® and the MRCOOL® Universal®. Series can replace almost any Central System on the market with an innovative new DC Inverter Heat Pump that works more efficiently at much lower temperatures.

We expanded with wireless and smartphone technology, allowing you to control your MRCOOL® ductless mini-splits from anywhere. But that wasn't enough. And we improved the MRCOOL® SmartHVAC Controller® module and smartphone app and made our mini-splits compatible with Google Assistant® and Amazon Alexa®. MRCOOL® GeoCool® Geothermal Systems are the Best in their Class for High-End Performance and Efficiency. GeoCool® Geothermal Package Units are an unmatched Eco-Friendly HVAC Solution.
