GREE EXTREME ULTRA HEAT Wall Heat Pump (38 SEER) 12,000 BTU distributed and installed in Greater Montreal by AirGreen Air Conditioning & Heating.

One in three heat pumps worldwide is manufactured by the largest HVAC (heating, ventilation & air conditioning) company, GREE. Thanks to an inevitable series of tests and quality controls, its innovative new technologies, and the proven reliability of its products over time, GREE has become the global leader in wall heat pumps! All this while consistently offering the best price on the market!

The EXTREME heat pump is designed to withstand the extreme conditions of our Canadian climate. Especially during intense cold periods, it offers cozy comfort down to temperatures as low as -30°C, without compromising its performance and, most importantly, your well-being. GREE equips the EXTREME outdoor unit (the compressor) with a special base featuring a heating element that prevents condensate freezing and ensures the unit’s full efficiency, as well as maximum heating power regardless of the outside temperature, all at the best price.

MAIN FEATURES:

ENERGY STAR® ACROSS THE ENTIRE EXTREME SERIES

The 12,000 BTU GREE EXTREME ULTRA HEAT wall heat pump is Energy Star® certified, making it eligible for federal and provincial government rebates, up to $5,600 throughout Greater Montreal, Laval, Longueuil, North Shore, and South Shore..

INTELLIGENT COMPRESSOR DEFROST

During the cold winter period, in heating mode, microprocessor-controlled defrosting occurs only when needed to maximize energy and cost savings. All this works to provide you with maximum heating capacity down to -30°C.

GREE’S UNIQUE HIGH-EFFICIENCY G10 INVERTER TECHNOLOGY

Most wall-mounted heat pumps worldwide operate at a fixed speed, which inevitably causes frequent stops and starts and consequently unnecessary electricity expenses. GREE’s patented G10 Inverter technology allows the desired room temperature to be reached faster while reducing your Hydro-Québec bill. The GREE EXTREME wall-mounted heat pump can therefore maintain an adequate setpoint and stands out from the competition with a compressor consumption as low as 45W. The G10 technology also ensures much quieter operation by reducing compressor vibration and noise.
