Real context of the AirGreen intervention

In this Ville-Marie condo, the heat pump is installed above a patio door , a very common configuration in urban units. This position allows for good air circulation, but it also requires rigorous checking of the airflow , the motorized damper, and the filter, since the unit often operates continuously, both for cooling in the summer and heating in the winter.

During our visit, the client wanted:

• optimize air quality ,

• to ensure stable operation in cold weather

• prevent any loss of performance due to fouling.

• a decrease in energy efficiency,

• an increase in operating noise,

• less healthy air (dust, allergens),

• premature wear of internal components.

At AirGreen, we recommend at least one annual maintenance , ideally before winter or before the air conditioning season, especially in condos in Ville-Marie where heat pumps are used intensively.
