Installation of a Goodman (wall-mounted series) wall-mounted heat pump in Laval (Chomedey)

Precise comfort and visual sobriety for a suburban Laval living room
At AirGreen , we work in Laval (Chomedey) on residential projects where the requirement is twofold: daily performance and discreet integration . This installation of a Goodman wall-mounted heat pump meets these expectations exactly: an interior head placed high on the wall, a properly covered refrigeration passage in white, and air diffusion that covers the space without creating a draft in the living area.

Customer context and performance objectives

The owner wanted:

• stabilize the temperature of the living room and the adjoining open area in summer and winter;

• reduce energy bills compared to electric convectors;

• enhance interior aesthetics with a compact and understated wall head;

• benefit from a reliable local HVAC service for maintenance.

We confirmed that the room configuration and access to the exterior wall made the wall-mounted heat pump the most suitable solution: excellent modulation, low consumption, simple maintenance, and comfortable acoustics.

Choice of location: even diffusion and discretion

To optimize air circulation:

• the head is installed in a corner , a few centimeters from the ceiling, guaranteeing minimal stratification and efficient recirculation of hot air in winter;

• the unit avoids any obstruction (rod and curtains on the left) so that the shutter can sweep the room;

• the alignment respects the aesthetics of the interior finishes (white wall, white hood, screwing in anchors adapted to the support).

This position allows you to cover the open area while limiting air returns disturbed by curtains, often neglected during hasty installations.

Installation details: cleanliness of execution and longevity

Our HVAC teams apply a strict protocol:

• Careful outward drilling (core of adequate diameter), controlled slope;

• Calibrated refrigeration lines , nitrogen brazing and deep vacuum with stability recording to prevent any residual humidity;

• White interior capping for a clean finish and easy maintenance;

• Gravity condensate drainage , with continuous slope to the outside, avoiding noise and maintenance of a micro-pump when the configuration allows it;

• Wiring and communication correctly crimped and marked, in accordance with good HVAC practices and Goodman specifications;

• Nitrogen leak test , then gradual commissioning (checking for overheating/undercooling, intensity control, measurement of supply/return temperatures).

Why Goodman for this project?

The Goodman brand offers reliable wall units, appreciated for:

• efficient modulation in partial load;

• contained acoustics on the interior side;

• easily accessible filters for routine maintenance;

• a simple and robust design , useful in main residences occupied year-round.

In this Chomedey home, the priority was thermal stability and visual sobriety . The Goodman wall-mounted series meets these criteria, while remaining economical to use compared to direct electric heating.

Sizing and load calculation method

Rather than imposing an arbitrary capacity, we size by load :

• surface area, free height, orientation and solar gain ;

• envelope (windows, infiltration, insulation);

• open area configuration (adjacent areas, stairwell, corridors).
  The result directs us towards the BTU capacity corresponding to the actual usage regime, to avoid oversizing (stops/restarts, drop in efficiency) and undersizing (insufficient comfort at the extremes).

Result: tangible comfort and controlled consumption

After commissioning and balancing:

• uniform temperature in the living area;

• dehumidification in air conditioning mode which improves the summer feeling;

• low operating noise, compatible with part life;

• reduced temperature rise time in the off-season.

The customer now benefits from regular comfort without variations, with a simple strategy: stable setpoint, automatic ventilation mode and maintained filters.

Notable technical points of this installation

• Ideal installation height to promote stratification and recovery through resumption;

• Short route from refrigeration lines to the exterior wall, limiting losses and improving response;

• White cladding matching the wall, for clean visual integration ;

• Gravity condensate management : increased reliability, no pump maintenance.

HVAC maintenance: ensuring performance over time

We offer structured HVAC maintenance :

1. Cleaning and inspection of filters and exchanger;

2. Drain check (slope, cleanliness, exit point);

3. Electrical control (terminals, currents, connections);

4. Validation of refrigeration parameters (signs of leakage, abnormal frost);

5. Updated usage instructions (setpoint ranges, dehumidification mode, absence management).

Annual maintenance maintains energy performance and extends the life of components.

Usage tips for optimal comfort

• Maintain a stable setpoint rather than marked daily variations;

• Leave the ventilation on auto to follow actual needs;

• Keep 0.5 m free in front of the facade for unobstructed airflow;

• Gently vacuum the air intake and wash the filters according to the frequency of use;

• In a heatwave, start the unit upstream rather than waiting for the room to overheat.

Grants and Eligibility

Efficient wall-mounted heat pumps may, depending on the configuration and current programs, be eligible for energy assistance in Quebec. We verify potential eligibility for each project and guide our clients through the process. Criteria include seasonal performance and cold weather operating range . Our team guides homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore to seize available opportunities.

Why AirGreen in Laval, Montreal and surrounding areas?

Our approach is based on:

• robust and transparent technical assessments ;

• clean and sustainable installations (tests, vacuum gauges, nitrogen brazing, calibration);

• responsive local after-sales service ;

• clear advice that allows you to fully exploit the equipment.

What if your project had constraints?

Tight corners, complex passages, flat roofs, additional lengths, multi-zones, or integration into a renovation: we adapt the line route , external supports , condensate management , and the diffusion strategy . The objective remains the same: lasting comfort , energy savings and impeccable finish .
