  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.

Exceptional Comfort with a Whisper: The Tosot LomoPlus Mini Split

A Tale of Innovation and Customer Satisfaction

When it comes to enhancing the comfort of your home with the latest in HVAC technology, the choices you make matter. At AirGreen, we understand that each installation is more than just fitting a machine; it’s about delivering a solution that aligns perfectly with your lifestyle and needs. This belief was vividly illustrated in our recent project in the bustling Villeray–Saint-Michel–Parc-Extension neighborhood of Montreal, where precision met preference to create an optimal living environment.

Project Overview

Our team at AirGreen recently had the pleasure of installing the Tosot LomoPlus UltraHeat Mini Split, a top-tier heat pump known for its robust performance and silent operation. This model, a beacon of efficiency with a 30.5 SEER rating and the capacity to perform even at -30°C, ensures that comfort is never compromised, regardless of the weather outside.

Client-Centric Installation

The installation site was a quaint residence where balcony space is treasured and peace is paramount. Our client’s request was clear – maximize balcony space and minimize noise. Adhering to their needs, we strategically placed the outdoor unit high on the wall, not only preserving valuable outdoor space but also ensuring that the unit operates unobtrusively, nestled between two windows. The interior unit was installed with minimal disruption, blending seamlessly into the space with its compact and sleek design.

Technical Precision

Our installation process is a testament to our commitment to detail and quality. The LomoPlus UltraHeat comes equipped with features that make it a standout choice. The unit supports Wi-Fi connectivity, allowing temperature adjustments from any smartphone. Its Energy Star® certification reflects its energy efficiency, a crucial factor in today’s environmentally conscious market.

Specifications at a Glance:

  • Cooling and Heating Capacity: 12,000 BTU
  • Sound Pressure Level: 22 dB(A) indoors, ensuring near-silent operation
  • Efficiency: 30.5 SEER, translating to significant energy savings
  • Warranty: Robust 10-year coverage on compressor, parts, and labor

Enhanced Features for Optimal Comfort

Intelligent Design

The LomoPlus is designed with user comfort in mind. Features such as the intelligent defrost system and memory function adapt to environmental conditions and user settings to optimize performance without manual intervention.

Special Features for Enhanced Usability:

  • Wireless Control: Adjust settings remotely for ultimate convenience.
  • Turbo Function: Achieves desired indoor temperatures swiftly.
  • Self-Diagnosis: Streamlines maintenance by notifying technicians of specific issues, reducing downtime.

Client Feedback and Satisfaction

Post-installation, the feedback was overwhelmingly positive. The client appreciated the thoughtful placement of the unit, which not only enhanced the balcony’s usability but also ensured a peaceful indoor environment. The professional demeanor and meticulous attention to detail by our AirGreen team did not go unnoticed.

At AirGreen, your comfort is our command. Our installations go beyond mere technical setups; they are crafted experiences tailored to your unique needs. Whether it’s facing the frosty climes of a Montreal winter or the swelter of summer, trust AirGreen to provide a solution that not only meets but exceeds expectations.

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.
