Description
This MRCOOL DIY 5th Gen 2-zone ductless mini-split system pairs a 55,000 BTU condenser with a 24,000 BTU and an 18,000 BTU wall-mount air handler, letting you heat and cool two larger rooms without hiring an HVAC professional. The condenser is rated at SEER2 22 and HSPF2-4 10.6, and its pre-charged Quick Connect line sets use R-454B refrigerant to skip the evacuation and vacuuming steps of a traditional install.
Highlights
- Pre-charged Quick Connect line sets (R-454B refrigerant) and the included DIYPro cable let you install the system yourself, with no electrical conduit or refrigerant vacuuming required.
- A 24,000 BTU wall-mount air handler (rated for spaces up to 1,050 sq. ft.) pairs with an 18,000 BTU wall-mount air handler (up to 800 sq. ft.) for two independently zoned rooms.
- Smart HVAC app (iOS/Android) with Amazon Alexa and Google Assistant compatibility for schedules, mode control, and energy monitoring.
- Follow Me function on the included remote adjusts airflow based on the remote's location; Dry Mode helps manage indoor humidity.
- Gold Fin condenser coil offers added corrosion resistance for long-term outdoor durability, including coastal climates.
- Backed by a 5-year parts warranty, 7-year compressor warranty, and a Limited Lifetime Replacement warranty with MRCOOL Care Program enrollment.
