The MRCOOL® Advantage 5th Generation 24,000 BTU Mini-Split Heat Pump delivers powerful, energy-efficient heating and cooling for spaces up to 1,050 sq. ft. This single-zone ductless system includes a WiFi-enabled air handler and a corrosion-resistant outdoor condenser with Gold Fin® coating, designed for extended durability in coastal and humid conditions. The use of R-454B refrigerant significantly reduces environmental impact, offering approximately 80% lower Global Warming Potential than older R-410A systems.

With a SEER2 rating of 18.7 and HSPF2-4 of 9.3, this system ensures reliable performance while keeping energy consumption low. Control your comfort remotely using the MRCOOL® SmartHVAC app or voice assistants like Amazon Alexa and Google Assistant. The included remote features Follow Me® functionality, automatically adjusting temperature based on your position in the room.

Additional features such as ultra-quiet operation, timer mode, leak detection, and built-in diagnostics support a modern, comfortable, and safe environment. A licensed HVAC professional must install the system to ensure optimal performance and warranty protection.

BTU Size Chart

Which BTU rating should I choose?

• The appropriate BTU rating depends on the size of the space you need to heat or cool.
• A higher BTU indicates greater heating and cooling capacity, allowing the air handler to effectively condition larger areas.

*Ceiling height, insulation quality, and local climate can all affect the actual coverage area. For instance, an uninsulated space will need more BTUs to maintain comfort compared to a well-insulated room.
