Built for true do-it-yourself installation, it requires no specialized tools, HVAC certifications, or prior experience, making it an excellent solution for garages, basements, attics, bonus rooms, and other spaces up to 800 square feet.

Once installed, control is effortless. The included wireless remote and the MRCOOL® Comfort app allow you to adjust temperatures, create schedules, and monitor energy usage from virtually anywhere. Amazon Alexa and Google Assistant compatibility adds hands-free voice control for added convenience.
Comfort-enhancing features such as Dry Mode, Sleep Mode, Auto Mode, and programmable scheduling automatically balance comfort and efficiency, while the Gold Fin® condenser coating provides superior corrosion resistance for humid or coastal environments.
For added peace of mind, the EasyPro® 18K is backed by a 5-year compressor warranty and a 3-year parts warranty, reflecting MRCOOL®’s confidence in the durability and quality of every system.

Manufacturer Warranty

In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.
