  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

A Showcase of Expertise and Innovation

At AirGreen, we are not just installing HVAC systems; we are enhancing comfort and delivering efficiency tailored to your individual needs. One of our recent projects in Montreal is a testament to this commitment, where we installed the highly acclaimed Gree Sapphire Wall-Mounted Heat Pump. This installation was not just about adding a heating and cooling solution but transforming how our clients experience their indoor environment during both sweltering summers and bone-chilling winters.

Project Overview and Specifications

The centerpiece of this project was the Gree Sapphire Heat Pump, renowned for its exceptional efficiency and smart technology integration. This unit boasts a robust 18,000 BTU capacity, ideal for substantial spaces requiring consistent temperature control. Key to the selection of this model was its outstanding features:

  • 24.5 SEER Efficiency: Ensuring optimal energy use while lowering utility bills.
  • Energy Star® Certification: A mark of its environmentally friendly design.
  • Wi-Fi Capability: Allowing seamless control through the GREE+ app, even when you're away from home.
  • Advanced Filtration Options: Providing cleaner air to breathe, which is essential for health and comfort.
  • Smart Features: Including a sleep function, timer, lock mode, and self-diagnosis for easy maintenance.

Moreover, the unit is equipped to handle extreme temperatures, offering ultra-efficient heating down to -30°C, making it a perfect ally against Montreal's harsh winters. The indoor and outdoor components are designed to operate quietly, maintaining a peaceful home environment with sound levels as low as 34 dB(A) indoors.

Installation Challenges and Custom Solutions

The location in Montreal posed specific challenges due to the compact urban setting and the client's requirement for minimal disruption to the existing aesthetic of their home. Our team navigated these challenges by strategically placing both the indoor and outdoor units to blend seamlessly with the building's facade. The outdoor unit was mounted in a position that optimized performance while being unobtrusive, ensuring not to detract from the building's exterior charm.

Custom piping solutions were implemented to accommodate the unique layout of the home, ensuring efficient airflow and system longevity. Additionally, the installation included a dual drain pump system to handle the high humidity levels typical in Montreal, thereby preventing condensation issues and ensuring continuous, efficient operation.

Client-Centric Approach and Results

From the initial consultation through to the final testing, our approach was highly client-centric. We prioritized understanding our client's specific needs and preferences, which guided our recommendations for the Gree Sapphire model. Post-installation, the client has reported a significant improvement in comfort levels, with the added benefit of reduced energy consumption due to the system's high efficiency.

The $1,704 LogisVert Grant by Hydro-Québec was a significant factor in making this project appealing from a financial standpoint, as it helped offset the initial investment cost, providing not only an eco-friendly solution but also an economically sensible one.

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.

    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.
