4-season comfort in a hard-to-access stairwell
When it comes to energy efficiency and performance in extreme cold, few heat pumps rival the Senville AURA 12,000 BTU , a solution renowned for its heating capabilities down to -30°C , its SEER of 22.5 , and its proven reliability. Recently, at AirGreen , we had the opportunity to install this compact yet powerful unit in a single-family residence located on the South Shore of Montreal . The installation presented a unique challenge: positioning the wall-mounted unit directly above a narrow staircase , requiring precision, strategy, and expertise.
Project context: An HVAC solution for a complex space
The client approached us with a clear need: to improve thermal comfort in a central entrance hall , located at the top of a staircase leading to the basement. This area was previously difficult to heat evenly, and a conventional solution such as an electric baseboard heater did not meet expectations.
Thanks to our free on-site evaluation, we immediately identified the Senville AURA 12,000 BTU as the ideal solution , combining:
-
Efficient heating down to -30°C (perfect for Quebec winters)
-
Compact format , allowing installation in tight spaces
-
DC Inverter Technology with Toshiba GMCC Compressor
-
Energy Star certification , guaranteeing significant energy savings

Installation: a challenge of access and positioning
The indoor unit had to be installed just above the door leading to the basement stairs —a very tight space, with little ceiling clearance, a narrow door frame, and height safety constraints. To successfully complete this delicate operation, our team:
-
Secure access with light scaffolding to protect the integrity of the wall and prevent any accidents at the top of the stairs.
-
Prepared a neat groove for the discreet passage of refrigeration pipes and electrical wiring.
-
Used a laser level to ensure perfectly horizontal positioning despite the inclined angle of the wall adjacent to the staircase.
-
Optimized the drainage of the condensation pipe, by routing it securely to the outside via a discreet elbow, without the risk of backflow.
End result: optimal performance in a small space
The client immediately noticed a major difference in thermal comfort , especially in the morning when the entrance hall previously remained cold and unpleasant. Thanks to the airflow directed towards the stairs and neighboring rooms , the wall-mounted heat pump now allows for even heat distribution on two levels.
Why did you choose the Senville AURA?
As experts in wall-mounted heat pump installation on the South Shore , we recommend the Senville AURA for several reasons:
-
Proven reliability in extreme Quebec climates
-
Very quiet , perfect for a passage area like a corridor
-
Discreet and modern design , blending well with residential decor
-
Easy maintenance thanks to front access to filters
Grants and Eligibility
In this case, the Senville AURA heat pump was not eligible for federal or provincial subsidies due to the R-410A refrigerant (less energy efficient than R-32 or R-454B). However, the customer was informed of eligible alternatives and chose Senville for its proven performance.
