  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.

A Winter Tale: When Heat Meets Cool Efficiency

In the heart of Montréal-Est, amidst the quiet symphony of falling snowflakes, AirGreen, a leading HVAC company known for its commitment to quality, efficiency, and customer satisfaction, embarked on a remarkable journey. This journey was not just about installing another HVAC system; it was about reinforcing trust, showcasing technological advancement, and delivering warmth in the chilling winter.

The Challenge of Height: A Story of Perseverance and Precision

Installing a Gree SAPPHIRE 18,000 BTU wall-mounted heat pump is an adventure in its own right. But when the task calls for mounting the compressor atop its predecessor, amidst the snowflakes of a Montréal winter, it becomes a tale of challenge and triumph. Our team, armed with expertise and a never-say-die attitude, found the perfect spot in the backyard to maximize available space without compromising on aesthetics or functionality.

Why Gree SAPPHIRE? A Closer Look at the Star of the Show

Choosing the Gree SAPPHIRE model was no mere coincidence. This decision was backed by a rich history of customer satisfaction and a keen eye on the future. The Gree SAPPHIRE, with its 24.5 SEER efficiency, WiFi connectivity, and Energy Star® certification, represents the pinnacle of HVAC technology. Its whisper-quiet operation, with sound pressure levels as low as 34 dB(A) indoors, ensures peace and comfort. The inclusion of R-410A gas and a formidable heating capacity that braves temperatures down to -30°C makes it a guardian against the cold.

Savings and Sustainability: The Financial and Environmental Edge

The story of this installation is incomplete without mentioning the $1,704 provincial grant that the SAPPHIRE model is eligible for. It's a testament to our commitment to not only provide the best in comfort and technology but also to ensure it's accessible. Moreover, the model's energy efficiency stands as a beacon of sustainability, promising long-term savings on energy bills and a reduced carbon footprint.

A Legacy of Trust and Excellence

Our journey with the customer did not start with the Gree SAPPHIRE. Three years prior, we had the pleasure of installing a Tosot heat pump, which marked the beginning of a trustful relationship. When the opportunity arose to upgrade to a more efficient model at a better price, our choice of the Gree SAPPHIRE was a nod to our enduring commitment to offer the best value to our clients. This decision was not merely about technical superiority; it was about acknowledging the trust and confidence our customers place in us.

Mastering the Elements: The Installation Day

On the day of the installation, as snow gently carpeted the world outside, our team of seasoned professionals demonstrated what makes AirGreen a leader in the HVAC industry. The installation, though challenged by the need to work at height and the whims of winter weather, was executed with unmatched precision and cleanliness. The sight of our team, undeterred by the snow, meticulously installing the state-of-the-art system, was a testament to our dedication to service excellence.

The Result: Beyond Just Warmth

As the system came to life, whispering warmth into the home, it was a moment of quiet pride for us. The Gree SAPPHIRE, with its sleek design and advanced features, was not just a heat pump; it was a beacon of comfort, efficiency, and reliability. The smile on our customer's face was a clear indicator of a job well done, a reminder of why we do what we do.

  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

And 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.

    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.
