A project to optimize comfort in a residential staircase
At AirGreen , we recently installed a Haier wall-mounted heat pump in a home located in Laval-des-Rapides . This residential area is characterized by its row houses and duplexes, which often require compact HVAC solutions capable of providing both efficient heating and cooling in hard-to-reach areas such as staircases.
Installing a wall-mounted appliance in a staircase represents a particular challenge: it is necessary to reconcile air circulation, ergonomics of use and safety of installation at height.
Why choose a Haier wall-mounted heat pump?
The Haier wall-mounted unit is a strategic choice for this type of space. Designed to offer four-season comfort , it effectively cools in the summer and heats in the winter, even when temperatures drop below -20°C.
Main features:
-
Brand: Haier
-
Type: wall-mounted heat pump (mini-split)
-
Available capacity: 9,000 to 12,000 BTU (ideal for covering transition areas such as stairwells or hallways)
-
Performance: SEER greater than 20, HSPF adapted to Quebec winters
-
Eligibility: eligible for energy subsidy programs (including LogisVert and energy-efficient homes), thanks to its low-temperature heating performance.
Technical details of the installation
Installation in this staircase required careful planning to ensure both efficiency and safety:
-
Installation height: high positioning on the upper wall of the staircase, ensuring optimal air diffusion to the upper and lower landings.
-
Drilling and refrigerant connections: a discreet wall-to-wall passage, with short connections (less than 4 meters), limiting energy losses.
-
Drainage: choice of a gravity drain , avoiding the addition of a condensate pump in a restricted space.
-
Capping: neat white cover, blending perfectly into the refined aesthetic of the light walls.
-
Safety: installation carried out with compact scaffolding adapted to the stairwell, allowing work at height without compromising precision.
Challenges encountered and solutions provided
The narrow staircases in some Laval homes pose a major challenge when installing wall units. In this case, it was necessary to:
-
Work with a reduced size of equipment to handle parts without damaging newly painted walls.
-
Optimize the heat pump's blowing angle so that the air circulates properly, without creating areas of cold or stagnant heat.
-
Take care of aesthetic integration in a passageway, by reducing the visibility of cables and conduits.
Thanks to the experience of our technicians, these constraints were successfully overcome, guaranteeing a result that was both efficient and harmonious.
Results obtained
As soon as it was switched on, the customer was able to see:
-
Temperature stability throughout the house, including between floors.
-
A significant improvement in air quality , with effective filtration of dust and allergens.
-
A reduction in energy consumption compared to the old auxiliary heating system used previously.
Comfort was thus improved, while increasing the energy value of the residence.
The importance of a professional AirGreen installation
Installing a wall-mounted heat pump in a staircase or complex space requires specific skills:
-
Management of installation height and ergonomics.
-
Compliance with electrical and mechanical safety standards.
-
Discreet aesthetic finishes.
At AirGreen, we don't just install a device: we adapt each installation to the architectural realities of your home , in order to maximize comfort and performance.
Whether you are in Montreal, Laval, Longueuil, on the North Shore or the South Shore , our team is committed to delivering durable, efficient and careful HVAC installations.
Recommended maintenance for the Haier heat pump
To extend the life of the heat pump and maintain optimal performance, we recommend:
-
Regular cleaning of filters (every 4 to 6 weeks during intensive periods).
-
Annual inspection by an AirGreen technician to check pressures, drain and heating efficiency.
-
Monitoring of the external clearance of the condenser to avoid any obstruction (leaves, snow, ice).
These simple actions ensure consistent performance and reduce the risk of costly breakdowns.
Conclusion
This Haier wall-mounted heat pump installation in Laval-des-Rapides perfectly illustrates our expertise: transforming a complex space into an optimized comfort zone. Thanks to rigorous planning and technical expertise, we delivered a durable, aesthetically pleasing solution perfectly tailored to the client's needs.
