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.

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.
