About this product

Installing your own HVAC system might sound overwhelming, but the 5th Generation MRCOOL® DIY® 12k BTU 23.5 SEER Ductless Heat Pump Single Zone Mini Split Condenser makes it simple and achievable. Designed specifically for easy installation, this system can efficiently heat or cool areas between 350 and 500 square feet—no professional tools or HVAC experience required. Thanks to the 25-foot pre-charged Quick Connect® line set filled with R-454B refrigerant, setup is straightforward and doesn’t require vacuuming. It’s a cost-saving, do-it-yourself solution engineered for safety and simplicity. You can control the system in multiple ways: use the included remote, the SmartHVAC app on iOS or Android, or voice commands via Amazon Alexa and Google Assistant. The built-in Follow Me® feature detects the temperature near the remote, adjusting output to match your location. For coastal homes, the Gold Fin® condenser coating provides rust-resistant protection, ensuring the system performs well over time. Comfort and energy savings are built in, with modes like Auto, Sleep, and Timer, plus auto-restart after power outages. Once installed, you'll enjoy a full suite of smart and efficient features. This model also comes with a base warranty that includes 7-year compressor/5-year parts coverage, along with eligibility for the MRCOOL® Care Program.
