Upgrade a wall unit for increased everyday comfort
In a typical duplex in the Rosemont–La Petite-Patrie neighborhood of Montreal , our team was tasked with replacing an old Neo Plasma wall-mounted heat pump . The unit, while still functional, was showing signs of wear after several years of service. The client wanted a complete upgrade to improve their comfort, optimize their energy consumption, and prepare their home for the coming seasons.
Why replace an aging wall-mounted heat pump?
Wall-mounted heat pumps, while efficient, gradually lose their efficiency after about ten years of use. In this case, the owner noticed:
-
A loss of heating efficiency in winter , especially on very cold days in Montreal.
-
An increase in electricity consumption compared to previous years.
-
More frequent operating noises .
These symptoms are common and indicate that a replacement is the best option to restore comfort and take advantage of new technologies.
Installation of the new unit
The project required careful planning:
-
Dismantling of the old Neo Plasma indoor head and existing refrigeration ducts.
-
Checking the tightness of old drillings to ensure a secure installation.
-
Installation of a new, latest-generation wall-mounted heat pump , better suited to the home's energy needs.
-
Refrigerant line routing carefully concealed for an aesthetic appearance.
-
Direct electrical connection to the panel to ensure safety and compliance with Quebec standards.
Choosing a new Energy Star certified unit allows the owner to be eligible for provincial grant programs (Hydro-Québec and LogisVert).
Immediate benefits for the customer
With this replacement, the owner now benefits from:
-
Reliable heating even at -25°C , thanks to the increased performance of the new unit.
-
A reduction in energy bills estimated at between 20 and 30%.
-
Improved comfort , particularly in rooms facing outside.
-
Quiet in operation , ideal for family life in a Montreal duplex.
Challenges encountered
The installation required some technical adjustments:
-
Limited height near the ceiling, requiring our technicians to adapt the installation angle of the interior head.
-
Management of old conduits : some were able to be reused after thorough cleaning, which reduced costs and accelerated the work.
Customer Testimonial
The owner said he was fully satisfied with the result:
"My old heat pump had outlived its usefulness. With the new AirGreen installation, I immediately feel the difference, especially in the evening when the temperature drops. The service was fast and very professional."
