Experience reliable comfort throughout the year in two large zones with the MRCOOL DIY® Multi-Zone 36,000 BTU 23 SEER 2-Zone Ductless Heat Pump Split System – 18K + 18K. Designed with true do-it-yourself installation in mind, this 5th Generation MRCOOL DIY Series system delivers powerful heating and cooling without the need for special tools, HVAC training, or costly installation fees.
Equipped with two 18,000 BTU indoor air handlers (ideal for up to 800 sq. ft. each), this ductless mini-split provides efficient comfort for larger rooms, apartments, or open floor plans. With a 23 SEER high-efficiency rating, you’ll enjoy lower utility bills while reducing your environmental impact thanks to the new eco-friendly R-454B refrigerant.
The 36K BTU condenser is strong enough to heat in winter, cool in summer, and dehumidify during wet seasons. Each indoor air handler offers wireless remote control, digital display with built-in diagnostic alerts, and smart operation modes including auto, sleep, drying, and emergency cooling. For modern convenience, connect your system to the MRCOOL Smart Controller app or control it hands-free with Amazon Alexa and Google Home.
This system includes pre-charged Quick Connect® line sets, allowing you to install without vacuum pumps, gauges, or refrigerant handling—saving you thousands of dollars. Backed by MRCOOL’s industry-leading warranty (7-Year Compressor + Limited Lifetime, 5-Year Parts), plus lifetime technical support, you can trust your DIY investment for years to come.
