🔥 Top Features & Benefits

Future-Proof Eco-Performance (R-454B)

Step into the future of HVAC with the new R-454B refrigerant. This 5th Generation system is environmentally advanced, offering an 80% lower Global Warming Potential (GWP) than older R-410A models. You get a system that is compliant with new regulations and better for the planet.

Smart Home Ready

Control your comfort from the palm of your hand or the sound of your voice. The built-in Wi-Fi connects seamlessly to the SmartHVAC app, Google Assistant, and Amazon Alexa. Turn the unit on before you get home or adjust the temperature without leaving the couch.

\"Follow Me\" Precision Comfort

Standard thermostats measure temperature at the wall, which can leave you too hot or too cold. The MRCOOL remote features Follow Me® technology, which senses the temperature at the remote\'s location—right where you are sitting—and adjusts the unit to ensure you feel exactly the temperature you set.

Whisper-Quiet Operation

Experience cooling that is felt but not heard. With indoor noise levels as low as 18 dB(A), this unit is significantly quieter than a library, ensuring uninterrupted sleep and distraction-free work.

Built for Durability (Gold Fin®)

The outdoor condenser is equipped with Gold Fin® technology, a specialized corrosion-resistant coating that protects the unit from salty air, rain, and other corrosive elements. This ensures a longer lifespan, even in coastal environments.

📋 Technical Specifications

⚠️ Installation Requirement

Professional HVAC Technician Required

Please Note: The MRCOOL Advantage Series is distinct from the MRCOOL DIY Series. While it includes a 16ft line set for convenience, this system requires professional installation by a licensed HVAC technician to vacuum lines, charge refrigerant (if lines are extended), and ensure proper electrical connections. It is the perfect choice for homeowners who want MRCOOL quality but prefer to hand the installation work off to a pro.
