Product Description

MRCOOL® DIY® 5th Gen Hyper Heat Single Zone Mini-Split Condenser

The MRCOOL® DIY® 208/230V Hyper Heat Ductless Heat Pump Single Zone Mini Split Condenser delivers powerful, high-efficiency climate control with simple do-it-yourself installation—no special tools, training, or professional assistance required. It is compatible with both our sleek wall-mounted air handlers and the low-profile DIY® OuttaSight® Ceiling Cassette.

Installation is fast and straightforward thanks to the 25-foot QuickConnect® line set, filled with environmentally-friendly R-454B refrigerant—eliminating the need for vacuuming or handling refrigerant. The included DIYPRO® cable enhances system protection, replacing traditional electrical conduit to guard against weather, pests, and yardwork damage.

Enjoy flexible control with multiple options: the included remote, the SmartHVAC app for iOS and Android devices, or voice control through Amazon Alexa and Google Assistant. The corrosion-resistant Gold Fin® condenser coating is designed for durability, making it ideal for both inland and coastal environments.

This system is loaded with smart features, including Auto-Restart to maintain continuity of comfort after power loss, a programmable Timer to correspond to your schedule, and the Sleep function, which increases efficiency while you sleep.

For peace of mind, the unit comes standard with a 7-year compressor and 5-year parts warranty with eligibility for the MRCOOL® Care Program.
