A clean, quiet installation designed for our winters — by AirGreen
Customer context and objective
At AirGreen , we were commissioned in Chomedey (Laval) to modernize the comfort of a single-family home with a Sharp wall-mounted heat pump . The request: a discreet system, efficient in air conditioning in the summer and efficient in intermediate heating in the spring/fall, with a durable and aesthetic HVAC installation .
Equipment Overview
-
Brand: Sharp ( Eco Inverter and Plasmacluster technology for better air quality).
-
Type: mini-split wall-mounted heat pump (outdoor condenser + indoor head).
-
Refrigerant: recent generation compliant with current requirements (installation ready for applicable efficiency programs).
-
Noise and efficiency: modulating operation, ideal for reducing on/off cycles and consumption.
Desired result: stable comfort, controlled energy bills and optimized air quality thanks to Plasmacluster ionization.
What we delivered
Neat and perfectly aligned refrigeration path
-
White capping (technical chute) vertical for approximately 2.5 to 3 m , then horizontal section to neatly reach the entry point.
-
Single perforation with vapor barrier and continuous insulation of refrigerant connections to limit losses and condensation.
-
Communication and power cabling grouped in the same trunking for a clean appearance and easy maintenance.
Outdoor installation designed for the Quebec winter
-
Sharp condenser installed on sturdy wall brackets , clear of the ground to prevent snow accumulation and promote defrost flow.
-
Anti-vibration feet and level balancing to reduce noise transmission into masonry.
-
Side and rear clearances respected to ensure optimal airflow during defrost cycles.
Condensate management
-
Gravity drainage to the outside (no pump required), reducing maintenance and the risk of additional breakdowns.
-
Controlled slope and exit protected from passages to avoid icicles in winter.
Architectural integration
-
Harmonization of the white capping with the pale brick of the facade: rectilinear lines, minimal visible stainless steel screws, clean finishes to the right of the covers.
-
Installation height chosen to combine aesthetics, silence and service accessibility.
Construction site challenges and AirGreen solutions
1) Respect for clear masonry
The pale brick facade required a clean, straight and unblemished drainpipe.
Our approach: laser tracing, low-impact drilling, dust protection and careful sealing at the finish.
2) Snow/icing clearance
The ground receives accumulations at the bottom of the wall.
Our answer: brackets at calculated height, compliant rear clearance and fan orientation to evacuate hot air during defrosting without nuisance.
3) Mixed vertical + horizontal path
The inner head was located at the wall return.
Solution: a short, well-fixed horizontal section to reach the most discreet entry point and limit the refrigerated length.
Why this Sharp heat pump ?
-
Inverter modulation : adjusts power as needed, limits overconsumption and increases continuous comfort.
-
Air quality : Plasmacluster ionization reduces odors and particles indoors.
-
Reliability : proven components, clear service access, parts and support available in Quebec.
What this changes on a daily basis
-
Immediate comfort : gentle temperature rise, uniform air conditioning in summer.
-
Silence : controlled vibrations, exterior noise level reduced by installation on brackets and alignment of the blades during defrosting.
-
Savings : modulation + good sealing of the route reduce consumption compared to an all-or-nothing device.
Good HVAC Maintenance Practices
-
Clean the internal filters every 1–2 months during peak periods.
-
Gently rinse the outdoor unit in spring; clear leaves and snow around it.
-
Have annual HVAC maintenance carried out: pressure/temperature check, electrical tightening, defrost test and leak test.
Grants and Eligibility
Depending on the configuration (seasonal yields, nominal temperatures), programs may apply to Greater Montreal ( Montreal , Laval , Longueuil , North Shore , South Shore ). We support our clients to validate eligibility and optimize the file.
What AirGreen brings in addition
-
Route design : we think about the line before the drill—less length, less waste, better aesthetics.
-
Finishes : aligned capping, stainless steel fixings, clean seals, service labeling.
-
Service : local team, parts available and technicians trained in recent generations R-32 / R-454B .
Tips before choosing
-
Prioritize an installer who is proficient in defrosting : clearances and condensate drainage are essential.
-
Validate the planned refrigeration length ; beyond certain limits, refrigerant top-up and loss calculations are required.
-
Require a documented commissioning test (high vacuum, leak test, readings).
-
Think about maintenance from the moment you buy: filter access, card access, service release.
