Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

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

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

  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.

The job

Modern comfort in the heart of a historic Montreal neighborhood

In the leafy streets of Outremont , every detail counts when it comes to combining comfort and energy efficiency. One of our recent projects perfectly illustrates how aSharp wall-mounted heat pump is transforming residents' daily lives. The installation took place in a typical home in the area: standard ceilings, clean white walls, and a window overlooking an interior courtyard.

Why a Sharp heat pump for this home?

Choosing a Sharp wall-mounted heat pump is based on three essential criteria:

  • Climate versatility : capable of heating efficiently during Montreal winters and cooling in summer.

  • Compact and stylish : a discreet indoor unit that fits harmoniously above a door.

  • Energy efficiency : eligible for various grant programs, including LogisVert, thanks to its high performance.

Although the exact model was not specified, it is a unit from the Sharp wall-mounted range, renowned for its reliability and stable performance at low temperatures.

The particularities of the installation in Outremont

Every AirGreen project is unique, and this one was no exception. Here are the highlights:

Passage of conduits and wiring

  • The refrigerant and electrical connections were routed through the top of the wall, discreetly running along the partition to reach the exterior.

  • White capping was installed to standardize the route, ensuring an aesthetic finish.

Positioning the indoor unit

  • Placed above the room's entrance door, the wall unit optimizes air circulation.

  • This configuration allows the airflow to be directed towards the depth of the room, maximizing comfort.

Condensate management

  • The drainage was designed using gravity, thus limiting future maintenance.

  • A condensate pump would have been necessary if the outlet had been lower, but the layout of the premises made it unnecessary.

Building context

  • Old window air conditioner visible in another room, gradually replaced by a more modern wall-mounted system.

  • Logical transition: noise reduction, improved energy efficiency, and increased interior space.

Immediate benefits for occupants

The installation of this Sharp heat pump offered several concrete advantages:

  • All-season comfort : constant warmth in winter, coolness in summer.

  • Energy savings : the electricity bill is reduced compared to traditional electric heating.

  • Silence and acoustic comfort : the difference with the old window air conditioner is noticeable, especially in a rest room.

Grants available in Montreal and on the South/North Shore

Thanks to the performance of this heat pump, occupants can benefit from programs such as:

  • Hydro-Québec’s LogisVert , which promotes the installation of high-performance wall-mounted heat pumps.

  • Canadian Greener Homes Grant Program , partially covering purchase and installation costs.

AirGreen expertise at the service of comfort

At AirGreen , each project in Montreal, Laval, Longueuil, on the North Shore or the South Shore is carried out with the same rigor:

  • Preliminary analysis of housing constraints.

  • Choosing the equipment best suited to real needs.

  • Professional, fast and respectful installation of the premises.

  • Administrative support for access to subsidies.

Conclusion: a project representative of AirGreen know-how

This installation of a Sharp wall-mounted heat pump in Outremont demonstrates AirGreen's ability to modernize homes while respecting the unique characteristics of each Montreal neighborhood. Our customers now benefit from optimal thermal comfort and sustainable energy efficiency.

The steps

The big day, step by step

The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.

Step 1 of 9The on-site estimate

We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.

  1. The on-site estimateWe look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
  2. The quoteModel, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
  3. Getting readyFloors and furniture protected, wall plate position marked level, wall opening located.
  4. The wall openingA single opening, with the slope the drain needs to flow outside.
  5. The outdoor unitSet on a stand raised above the snow, with the clearances the manufacturer requires.
  6. Lines, cable and drainConnected, insulated and protected. The opening is then sealed against water, cold air and insects.
  7. The electrical workA dedicated circuit and an accessible disconnect near the outdoor unit.
  8. Tests and start-upLeak test, vacuum, then start-up and a check of heating and cooling.
  9. The walkthroughRemote, modes, filters: we show you the essentials before we leave.
Your numbers

What would it look like at your place?

Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.

Size checkYour baseboards, in BTU/h
–BTU/h of installed electric heat

    Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

    Through the seasons

    What to do, season by season

    Three habits per season for this unit. They take a few minutes and prevent many calls.

    • Clean the indoor unit's filters.
    • Clear leaves and debris left on the outdoor unit by winter.
    • Test cooling before the first hot days.
    At your place

    Is your home ready?

    Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.

    0 / 6 checked
    True or false

    Four statements: true or false?

    It all comes down to details you have just seen.

    1. In heating mode, the outdoor unit can produce water.

    2. You pick the capacity with a simple square-footage rule.

    3. A multi-zone connects several indoor heads to a single condenser.

    4. The disconnect can sit behind the patio furniture.

    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.
