FLEXX SERIES: GUD36W/A-D(U)

The Ducted Central Heat Pump, an energy-efficient heating solution that tackles the challenges of cold weather. Developed by GREE, it utilizes state-of-the-art technology to deliver powerful heating capacity even in outdoor temperatures as low as -30°C. Perfect for harsh Canadian winters, it helps curb climate change while providing optimal comfort.

Energy Efficiency

  • In Canada, the cold climate demands significant energy consumption for space heating. On average, space heating comprises a remarkable 61% of energy usage in Canadian homes and 56% in commercial and institutional settings. By implementing energy-efficient heating solutions, we can actively combat global warming while reducing energy consumption in both residential and commercial spaces.
  • Our product incorporates the eco-friendly R410A refrigerant, promoting environmentally conscious cooling practices. R410A is a chlorine-free refrigerant known for its exceptional energy efficiency and minimal impact on the ozone layer.


Home Comfort

  • Whisper-quiet operation: Enjoy a peaceful and serene home environment with our quiet design, ensuring minimal noise disruption during operation.
  • Our home comfort system boasts a wide operating range specifically designed for heating. From chilly autumn evenings to freezing winter temperatures, our system ensures optimal warmth and comfort throughout the colder months. With its ability to efficiently heat your home across a wide range of temperatures, you can rely on consistent and reliable performance, keeping you cozy regardless of the outside conditions. Say goodbye to cold spots and welcome a comfortably heated home with our wide operating range feature for heating.


Convenient Operation

  • Complete GREE Kit Installation: Opt for a hassle-free installation by selecting our comprehensive GREE kit, which includes all the necessary components for a seamless setup.
  • Retrofit with Third-Party Indoor Unit or Furnace: If you already have a third-party indoor unit or a furnace combined with a cased coil, you have the flexibility to retrofit our system, reducing both labor and equipment costs.


Reliable Function

  • Low Temperature Two-stage Compressor: Our heat pumps are equipped with a low temperature two-stage compressor, enabling efficient heating even in extreme climates with temperatures as low as -30¬∞c.
  • Full 3-DC Inverter: With the full 3-DC inverter technology, our heat pumps offer precise and intelligent temperature control, ensuring optimal heating and cooling performance.
