Four-season comfort in a basement family room: a careful integration that prioritizes silence, efficiency and uniform air diffusion.
Project context: wood-paneled family room, suspended ceiling and lateral space constraints
In Chomedey (Laval) , we are modernizing the comfort of a single-family home by installing a Gree wall-mounted heat pump from the Livo R32 range in a wood-paneled family room , typical of renovated basements with suspended ceilings . The client's objectives: improve air quality , stabilize the temperature all year round, limit electricity consumption and preserve the warm aesthetic of wood.
Thermal sizing: right capacity, true efficiency
Before any HVAC installation , we evaluate the envelope (wood-framed walls, slab, basement windows), the use (play area, TV, office), and the actual volume. In this type of space, the 9,000–15,000 BTU range covers the vast majority of scenarios. Our recommendation is based on:
-
the inverter modulation of the Gree Livo R32 range,
-
a clear air intake despite a side cabinet,
-
the need for low-noise blowing to remain comfortable during quiet activities.
Choice of the Gree Livo R32 range: performance, silence, new generation refrigerant
The Livo R32 range is distinguished by high seasonal efficiency , quiet operation , and precise flow control . R-32 reduces fluid load and improves heat exchange. For Greater Montreal, this range maintains solid performance in northern climates , ideal for basement heating and rapid cooling in summer.
Interior layout: high ceiling, longitudinal diffusion
We place the head high on the wall , just below the suspended ceiling , in order to:
-
maximize diffusion along the paneling,
-
avoid air returns against the vertical furniture located on the right,
-
facilitate HVAC maintenance (accessible filters, easy-to-remove front panel).
The vertical sweep distributes air beyond the furniture axis to reach the TV area and the play area. We maintain the required clearances on the right side so as not to hinder the suction. Anti-vibration pads and a calibrated anchor on a solid frame eliminate resonances on the paneling.
Condensate management: gravity-fed, silent and secure
The chosen wall faces outwards, which allows us to have a continuous gravity drain . We provide:
-
a constant slope of the pipe,
-
anti-condensation insulation ,
-
an accessible purge point .
This approach eliminates pump noise and reduces maintenance. The tank and pipe are disinfected during commissioning for optimal air quality .
Refrigerated path: short, protected and aesthetic
The core drilling is carried out neatly through the panelled partition and the insulation, with a watertight sleeve . Outside, the refrigeration lines (high-density insulated copper) follow a short route , under UV- and frost-resistant cover .
Quality procedure:
-
Nitrogen pressurization and drop control,
-
Deep vacuum until stabilization (vacuum holding),
-
Fluid opening , superheat/subcooling test, current/communications check.
Power supply: safety and compliance
The heat pump is powered by a dedicated circuit from the main panel. We integrate:
-
suitable circuit breaker according to the amperage,
-
service switch to the outdoor condenser,
-
grounding checked and tightening torque checked.
The communication links are drawn respecting the path of the suspended ceiling, with clear markings for future maintenance.
Commissioning and fine-tuning: comfort in a basement
In the family room, the perception of fresh air can be accentuated nearby. We therefore configure:
-
a stable setting and an Auto mode which modulates finely,
-
a sweep oriented to avoid direct blowing on the sofa,
-
a minimum speed in thermal maintenance for remarkable silence ,
-
eco-dehumidification during humid periods to limit the feeling of dampness in the basement.
Results: uniform temperature, almost imperceptible noise
The first surveys show:
-
a temperature difference < 1.5°C between the TV corner and the reading corner,
-
a comfortable air speed , without localized cold current,
-
a low sound signature , absorbed by wooded surfaces.
HVAC maintenance: simple actions, maximum longevity
To ensure performance and air quality :
-
Clean filters every 4 to 6 weeks during periods of heavy use.
-
Annual inspection : exchanger, fan, connections, refrigeration measurements.
-
Disinfection of the tray and drain, slope control.
-
External inspection : condenser clearance, condition of the cowling and supports.
An AirGreen maintenance plan maintains performance and manufacturer warranties .
Special technical points of a basement in Chomedey
-
Suspended ceiling : convenient access for wiring and drain , but increased vigilance on dew points ; we install continuous insulation of the lines.
-
Wooden paneling : precise anchors and anti-vibration interposition to avoid any resonance .
-
Side cabinet : we respect a suction clearance and direct the blowing to go around the obstacle.
Grants and supporting documents
Recent, high-efficiency , low-temperature wall-mounted heat pumps may be eligible for programs in effect in Quebec, depending on certification and performance range . We prepare the parts (device numbers, plate photos, detailed invoice) and support our customers in Montreal, Laval, Longueuil, North Shore and South Shore .
Deadlines and construction site management
Our methodology limits the immobilization of the part:
-
Protection (tarpaulins, painter's tape),
-
Clean drilling with dust collection,
-
Complete tests before departure,
-
Mini-training on use (modes, filters, best practices).
In a standard residential context, the intervention is carried out in one day , excluding any particular structural or electrical constraints.
Tips for maximizing savings
-
Maintain a stable setpoint and avoid extreme deviations.
-
Let the automatic sweep work; it equalizes the temperature beyond furniture and recesses.
-
Activate dehumidification during humid episodes for superior comfort without overcooling.
-
Plan maintenance ahead of peak seasons (early summer/early winter).
Common mistakes to avoid
-
Block the recovery with decorative objects or glued shelves.
-
Undersizing a semi-open area: high-speed cycles and unnecessary noise.
-
Neglecting the slope of the drain: odors and risk of overflow.
-
Ignore external condenser vents: loss of efficiency and premature icing.
