The MRCOOL® Advantage 5th Generation 36,000 BTU Mini-Split Heat Pump is designed to deliver high-capacity, energy-efficient heating and cooling for larger areas up to 1,550 sq. ft. This single-zone ductless system features a WiFi-enabled air handler and a corrosion-resistant Gold Fin® outdoor condenser, built to withstand harsh coastal or humid conditions. It uses R-454B refrigerant for a significantly reduced environmental impact, offering 80% lower Global Warming Potential (GWP) than traditional R-410A.

With an 18 SEER2 and 8.5 HSPF2-4 rating, this unit provides powerful yet economical climate control. Adjust settings remotely via the MRCOOL® SmartHVAC app or through voice control with Google Assistant or Amazon Alexa. The included remote offers Follow Me® mode, which automatically adjusts the temperature based on your location in the room.

Engineered for comfort, the system also features whisper-quiet operation, timer mode, leak detection, and built-in diagnostics. Professional HVAC installation is required to activate warranty coverage and ensure optimal performance.

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.
