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

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

Bringing Comfort Home with Sharp

Unmatched Installation at Deux-Montagnes

At AirGreen, we recently completed an exceptional installation of the Sharp ZU1 Wall-Mounted Heat Pump in Deux-Montagnes, a charming locale on the North Shore. This installation was not just about enhancing home comfort but also about smart energy use and maximizing homeowner incentives.

Choosing the Right Size: A Strategic Decision

Our client faced a common dilemma: the choice between a 12,000 BTU unit and a 15,000 BTU heat pump. With the Sharp ZU1 model, the decision became significantly easier. The Sharp ZU1 15,000 BTU unit, equipped with advanced features, not only fit the space perfectly but also qualified for the highest provincial grant available through Hydro-Québec's LogisVert program. This made the higher-capacity unit more cost-effective than even the entry-level alternatives.

Advanced Technology for Superior Comfort

The Sharp ZU1 stands out with its Plasmacluster air purification technology—a feature unmatched in the industry. Unlike standard air filtration systems, the Plasmacluster technology goes a step further to neutralize airborne bacteria, viruses, and mold, ensuring a healthier living environment.

Here’s how the Plasmacluster technology enhances your home:

  • Eliminates harmful pathogens: It actively neutralizes viruses and bacteria.
  • Reduces allergens and odors: Effectively breaks down odors and fights common allergens.
  • Improves overall air quality: Offers a fresher and cleaner indoor atmosphere.

Seamless Integration and Aesthetic Appeal

During the installation process, our team paid close attention to our client's specific needs, ensuring that the indoor unit was placed exactly where desired, despite the limited available space. This careful placement not only optimized the unit's performance but also maintained the aesthetic integrity of the home's interior design.

Energy Efficiency at Its Best

The Sharp ZU1 model is a testament to energy efficiency, boasting a 24.0 SEER rating and featuring the latest R-32 refrigerant, which reduces greenhouse emissions and lowers electricity consumption by about 10%. Additionally, this model comes with a comprehensive 10-year warranty on all parts, labor, and compressor, directly from Sharp, ensuring peace of mind and reliability.

Client Satisfaction and Continued Trust

The installation was a resounding success, culminating in a perfect final setup that exceeded our client’s expectations. The client was particularly impressed with the personalized service and the detailed attention to every aspect of the installation process. This project not only resulted in a highly satisfied customer but also led to further recommendations, expanding our business through genuine word-of-mouth.

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.

  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.

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.

Before / afterThe cost of the same heat

Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):

Before · baseboards11.142¢/kWh
After · heat pump–

Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.

Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.

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.

    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.
