Generic diagram: wall-mounted heat pump, indoor and outdoor units

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

Precise comfort in a Montreal condo, without compromising on aesthetics

At AirGreen , we design each HVAC installation as an engineering project applied to everyday life. In this condo located in Villeray–Saint-Michel–Parc-Extension , we installed a Gree Clivia R32 wall-mounted heat pump to provide reliable heating in the winter and gentle cooling in the summer, with discreet integration near a patio door. The goal: performance, silence, and visual sobriety, without encroaching on the living space.

Why the Clivia R32 range?

Gree 's Clivia R32 series combines inverter technology with a new generation R-32 refrigerant, with a lower global warming potential, while ensuring high performance in cold weather. It meets three common expectations of co-owners in Greater Montreal:

  • Superior energy efficiency to reduce electricity bill;

  • 4-season comfort with fine power modulation;

  • Quiet and compact design that fits into living spaces.


Context and constraints of the site

The housing has a typical urban layout: large glass opening, short wall corner, direct access to a terrace where the condenser is installed. These parameters require precise planning of passages and clearances.

Choosing an interior location

We positioned the wall head high and in a corner , a few centimeters from the ceiling, so as to:

  • Maximize air stratification and diffusion to the open area;

  • Free up the main walls for furniture;

  • Facilitate a short route of connections to the outside (crossing the side wall near the patio door).

Route and finishing of the connections

  • Estimated length of refrigeration connections: approximately 1 to 1.5 m, limiting pressure losses.

  • Discreet white capping , laid vertically then horizontally to join the drilling; fixings at regular center distance for a durable finish.

  • Gravity condensate drain with continuous slope (~2%), avoiding a pump and therefore additional noise/maintenance.

  • Crossing made with sheath and vapor barrier to preserve the building's watertightness.

Installation of the outdoor condenser

Visible from the patio door, the outdoor unit is mounted on wall brackets with anti-vibration pads . This anchor:

  • clears the ground and preserves the flow of defrost water;

  • ensures proper rear and side clearance ;

  • reduces the risks associated with frequent snow accumulation in Montreal .


Sizing and expected performance

We always size the heat pump based on the room's usage, orientation, and building envelope. Here, a 12,000 BTU configuration proved optimal for the main living area, with:

  • Competitive SEER/SEER2 and HSPF/HSPF2 for R-32 appliances;

  • useful heating capacity in negative temperatures, suitable for Greater Montreal winters;

  • intelligent defrosting limiting cycles and improving thermal stability.

Expected result: a significant reduction in costs versus electric baseboards and a low interior noise level , ideal for teleworking and condo living.


AirGreen methodology: rigor and cleanliness

Our signature is clean, verifiable and sustainable execution.

Key technical steps

  1. Site protection , tracing and verification of center distances.

  2. Drilling to the correct diameter , installation of an insulated sleeve and watertight sealing.

  3. Installation of insulated copper lines , bending radii respected.

  4. Nitrogen brazing or flared fittings to range specification, with torque controls.

  5. Nitrogen pressure test (high stage) and deep vacuum (≈ 500 microns ).

  6. Fluid release, leak check and functional measurements (intensity, supply/return temperatures, ΔT).

  7. Finishing: capping , caulking, repainting if required, instructions for use and maintenance.

Electrical management

  • Dedicated condenser circuit according to the nameplate;

  • Compliant circuit breaker and properly sheathed communication cable between units;

  • Installation of an external disconnect switch within easy reach for maintenance.


Daily comfort: what occupants feel

  • Rapid temperature rise in the off-season then gentle modulation.

  • In summer, laminar airflow directed along the ceiling to avoid direct currents on the sofa/dining table.

  • Silent night mode and dimmable display on the front.

  • Effective dehumidification during the humid waves of July-August in Montreal , Laval and Longueuil .


Aesthetics and integration

The Clivia R32 features a smooth white facade that blends into the light colors of the living room. The short passage to the outside allows for a minimalist cable channel , without an oversized box. On the terrace side, the brackets leave space for movement and avoid traces of corrosion on the floor.


Recommended maintenance (prevention > repair)

Light but regular HVAC maintenance extends the lifespan of:

  • Filters : gentle vacuuming every 1 to 2 months; washing with warm water if necessary.

  • Internal battery : periodic professional cleaning to maintain thermal exchange.

  • Outdoor unit : leaf/snow clearance (at least 30–60 cm on each side).

  • Annual inspection by our technicians for pressure and electronic checks.


Grants and Compliance

High-efficiency R-32 wall-mounted heat pumps are generally eligible for assistance programs in Quebec. We support our customers in Greater Montreal—including the North Shore and South Shore —in gathering the required technical documents (performance sheet, certification number, proof of installation) and optimizing the application .


AirGreen Tips for Condominiums and Plexes

  • Favor a gravity drain when the configuration allows it; reliability is superior.

  • Provide a wall support with buffers if the terrace is small or subject to snow.

  • Respect clearances to maintain optimal seasonal performance and limit noise.

  • Request a refrigeration charge check and documented vacuum draw upon commissioning.

  • Consider a second head if natural air distribution does not cover one wing of the dwelling.

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
    Is the estimate free?
    Yes. The on-site estimate is free and the quote follows within 24 hours. Book my free estimate.
