This MRCOOL DIY 5th Generation 4-Zone Mini Split pairs a 36,000 BTU ductless heat pump condenser with four ceiling cassette indoor air handlers rated at 9K + 6K + 6K + 6K BTU, giving each zone independent temperature control. The condenser is rated at SEER2 23 and HSPF2 9.9, and the system's DIY QuickConnect line sets come pre-charged with R-454B refrigerant, so installation doesn't require vacuuming or a licensed HVAC technician.
Highlights
- Pre-charged 25-ft DIY QuickConnect line sets (R-454B refrigerant) eliminate the vacuuming step, cutting installation time and cost.
- Included DIYPRO cable removes the need for electrical conduit while adding durability against outdoor elements.
- Control every zone from the included wireless remote, the SmartHVAC app (iOS/Android), or hands-free through Amazon Alexa and Google Assistant.
- Follow Me function tracks the temperature near the remote's location so each zone stays evenly comfortable.
- Rated SEER2 23 / HSPF2 9.9 for efficient year-round heating and cooling.
- Low-profile ceiling cassettes fit flush between standard 16" ceiling joists (including pre-manufactured I-joists) with no ductwork or extra wall space needed.
- Two-stage DC motor, Swing Technology, and an Elevation function that lowers the filter panel for easy cleaning.
