This MRCOOL DIY 5th Gen 2-zone ductless mini-split system pairs a 55,000 BTU condenser with two matched 18,000 BTU OuttaSight ceiling cassette air handlers, letting you heat and cool two mid-to-large rooms with a low-profile, flush-mounted indoor unit and no HVAC professional required. 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) let you install the system yourself, with no vacuuming or brazing required.
- Two 18,000 BTU ceiling cassettes, each rated for spaces up to 800 sq. ft., fit flush between 16" ceiling joists, including pre-manufactured I-joists, without ductwork or wall space.
- The Elevation function lowers each cassette's filter panel for easy access and cleaning, and advanced filtration helps improve indoor air quality.
- Whisper-quiet, two-stage DC motor operation with Swing Technology airflow distribution.
- Controllable via wireless remote, the SmartHVAC app (iOS/Android), or voice commands through Amazon Alexa and Google Assistant.
- Backed by a 5-year parts warranty, 7-year compressor warranty, and a Limited Lifetime Replacement warranty with MRCOOL Care Program enrollment.
