At AirGreen , we regularly work in Rosemont–La Petite-Patrie for the service, maintenance and diagnosis of Gree wall-mounted heat pumps , a typically Montreal area where brick facades, superimposed balconies and exterior wall installation require a precise and rigorous approach.
In this particular case, it's a Gree Inverter wall-mounted heat pump , a very common residential system for condos and duplexes in East Montreal. Since the exact model isn't clearly legible, we're referring to it as a new-generation Gree wall-mounted heat pump , consistent with the R-32 Inverter units we service daily.
Gree outdoor unit: visual observations and typical issues in Rosemont
The photo clearly shows a Gree outdoor unit mounted on a wall bracket, with direct access to the axial fan. We can see:
-
Significant accumulation of dirt, grease deposits and particles on the fan blades
-
The presence of soapy water indicates active deep cleaning.
-
High-rise installation, typical of Rosemont's brick buildings
-
Metal wall bracket exposed to freeze/thaw cycles
-
Refrigeration connections are protected, but require regular inspection.
In this type of dense urban environment, outdoor units are particularly exposed to dust, pollen, urban debris, and winter debris. Without proper maintenance, this quickly leads to reduced efficiency , increased noise , and premature wear of the fan motor .
Why maintaining a Gree wall-mounted heat pump is essential
Even though Gree heat pumps are known for their reliability and efficient Inverter technology, no system is maintenance-free. In Rosemont–La Petite-Patrie, we often see:
-
Reduced heating capacity during periods of extreme cold.
-
Defrosting more frequently than normal
-
Outdoor fan unbalanced due to deposits
-
Unnecessarily high electricity consumption
Professional maintenance helps to preserve winter performance , a critical point in Montreal's climate.
