  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 Stellar Upgrade for Sustainable Comfort

Embarking on a Comfort Journey

At AirGreen, we recently embarked on an intriguing installation adventure in the heart of Rivière-des-Prairies–Pointe-aux-Trembles, Montreal. Our mission was clear: replace an aging 12,000 BTU heat pump that was no longer meeting the homeowner’s comfort needs with a robust, efficient, and powerful Sharp THU Wall-Mounted Heat Pump.

Why the Sharp THU?

  • Size Matters: With a whopping 18,000 BTU, the Sharp THU doesn’t just cool; it dominates, providing unparalleled heating and cooling efficiency.
  • Multi Space Function: Unique to Sharp, this feature ensures uniform and balanced air distribution across multiple rooms, creating a harmonious living environment.
  • Customizable Comfort: The adjustable flap allows for personalized airflow direction, ensuring optimal comfort tailored to your preference.

Installation Chronicles: A Staircase Conundrum

Our journey began with a challenge. The previous 12,000 BTU unit perched atop a staircase had seen better days. With escalating repair costs and diminishing efficiency, a replacement was inevitable. Enter the Sharp THU - a beacon of efficiency and reliability.

The Installation Process: Precision Meets Expertise

  • Location: The strategic placement atop the staircase maximizes airflow and ensures consistent temperature regulation throughout the home.
  • Difficulty: With a medium difficulty level, our seasoned technicians navigated the installation process with precision and expertise, ensuring a seamless transition from the old to the new.

Sharp THU: A Symphony of Features

  • Cooling & Heating Mastery: With a cooling capacity of 18,000 BTU and the ability to heat efficiently even at -27°C, the THU is a true all-season companion.
  • Silent Operation: With sound pressure levels as low as 25 dB(A) indoors and 52 dB(A) outdoors, the THU operates whisper-quiet, providing comfort without the noise.
  • Energy Efficiency: Boasting a 21.0 SEER efficiency rating and Energy Star® certification, the THU is a testament to Sharp’s commitment to sustainable comfort solutions.

Grants & Warranty: Value Unmatched

  • Federal & Provincial Grants: With eligibility for substantial grants, investing in the THU is not just a choice for comfort but also a financially savvy decision.
  • Warranty: A comprehensive 10-10-10 warranty (Compressor - Parts - Labor) with an included extended warranty offers peace of mind for years to come.

Conclusion: A Comfort Revolution

With the Sharp THU Wall-Mounted Heat Pump, comfort has been redefined and elevated. Its installation at Rivière-des-Prairies–Pointe-aux-Trembles is a testament to AirGreen’s commitment to delivering sustainable, efficient, and unparalleled HVAC solutions to the residents of Montreal, Laval, Longueuil, North Shore, and South Shore.

The steps

How it goes, from the first call to the end

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

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.
