Whole-room comfort, zero contractors required. The MRCOOL® DIY® Easy Pro® 18,000 BTU mini-split heat pump was built for the spaces that demand more — open-plan living areas, large master suites, finished basements, and oversized home offices up to 800 sq. ft. The included 11.5 ft. pre-charged Quick Connect® line set ships factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, manifold gauges, or an HVAC license. Variable-speed inverter technology delivers up to 20.0 SEER2 cooling efficiency and 8.5 HSPF2-4 heating efficiency on a standard 208-230V circuit, while built-in Wi-Fi connects seamlessly to the MRCOOL® Smart HVAC Controller®, Amazon Alexa, and Google Assistant. A 5-year compressor warranty, 3-year parts warranty, and ETL certification round out a system engineered to perform well beyond its price point. Professional comfort. DIY® price tag.
- True DIY Installation: No HVAC license, no vacuum pumps, no manifold gauges. The included 11.5 ft. pre-charged Quick Connect® line set arrives factory-sealed with R-454B refrigerant, so there is nothing to charge, no specialized equipment to rent, and no contractor to schedule.
- Energy Savings: DC inverter compressor technology modulates output continuously to match actual load, bypassing the energy-wasting on/off cycling of conventional systems. At up to 20.0 SEER2 and 8.5 HSPF2-4, the 18K Easy Pro® delivers efficient performance year-round
- Comfort in Any Climate: Reliable operation across an extreme ambient temperature range of -13°F to 122°F means this system works when it matters most, whether that is a hard freeze in January or a heat wave in August.
- Whisper-Quiet Operation: Five fan speed settings include an ultra-quiet Sleep mode at just 18.5 dB(A), making the 18K unit as unobtrusive in a bedroom as it is powerful in a great room. Even at maximum output, indoor noise stays at a manageable 46.5 dB(A), well below the threshold of distraction.
- Easy Maintenance: Washable, reusable filters mean no recurring replacement costs and a two-minute cleaning routine. The Gold Fin® corrosion-resistant condenser coating shields the outdoor unit against humidity and environmental wear for long-term durability without any special upkeep required.
- Worry-Free Warranty: Backed by a 5-year compressor warranty and a 3-year parts warranty, with ETL certification confirming compliance with North American safety standards.
