Modernization of a residential HVAC system in Laval-des-Rapides
At AirGreen , we were commissioned to replace an old Hitachi wall-mounted heat pump in a condo in Laval-des-Rapides . The client wanted to maintain the reliability of their unit while improving the energy efficiency of their home, and we handled every step of the project, from the initial assessment to commissioning.
The context of the installation
The existing equipment was already several years old. Although it was still functioning, its performance was no longer optimal:
-
Increased electricity consumption.
-
Temperature fluctuations in the living room and bedroom.
-
More noise due to fan wear.
Rather than waiting for a complete breakdown, the owner chose to act proactively to ensure stable comfort all year round .
Technical details and AirGreen approach
Our team proceeded to dismantle the existing wall unit, taking care to preserve the wall surfaces and moldings. For the new installation:
-
Strategic positioning at height , allowing optimal diffusion of air in the living room.
-
Partial reuse of refrigerant pipes , after inspection and replacement of non-compliant sections.
-
Gravity condensate drain maintained, limiting the risks of breakdown associated with mechanical pumps.
-
Careful sealing to prevent any infiltration of outside air.
We also adjusted the piping length to meet the manufacturer's recommendations, ensuring adequate refrigeration pressure and maximum energy efficiency.
Constraints encountered and solutions implemented
One of the main constraints was the proximity of the ceiling and decorative moldings. Our technicians had to adapt the wall brackets so that the device would fit perfectly without altering the aesthetics of the room. The end result offers precise and discreet alignment , with an impeccable finish.
Benefits for the customer
By choosing a new Hitachi wall-mounted heat pump , the customer now benefits from:
-
Four-season comfort , with efficient heating in winter and effective air conditioning in summer.
-
Significant energy savings thanks to higher efficiency and better consumption management.
-
A quieter environment , with a much quieter device than the old model.
-
Peace of mind linked to the guarantees offered and AirGreen monitoring.
