An exclusive investigation into the false promises that mislead Montreal consumers searching for a reliable, high-performance wall-mounted air conditioner
In the world of residential HVAC, many consumers across Montreal, Laval, Longueuil, the North Shore, and the South Shore rely on salespeople’s recommendations to choose a wall-mounted air conditioner suited to their needs. However, behind some of these attractive promises lie half-truths, sales exaggerations, and even misleading information. At AirGreen, we’ve decided to pull back the curtain on these practices to help customers make informed choices and avoid costly surprises.
Lie #1: “All wall-mounted air conditioners are the same”
What some salespeople conveniently leave out is that the quality of wall-mounted air conditioners varies widely depending on the brand, model, and technical specifications. A low-end unit might seem appealing due to its price, but it’s likely to:
-
break down more quickly,
-
consume more electricity,
-
deliver uneven cooling performance,
-
and not qualify for LogisVert or Chauffez Vert grants.
At AirGreen, we only recommend proven units, such as GREE, Fujitsu, or Daikin models, known for their durability, energy efficiency, and quiet operation.
Lie #2: “Installation is quick, no matter the house”
Some salespeople would have you believe that an HVAC installation is always fast and easy. That’s simply not true. Every home is different. Here are a few real-life examples from our projects in Laval and Brossard:
-
A century-old stone house required specialized core drilling and advanced thermal protection.
-
A high-rise condo in Montreal had restricted outdoor access, which extended the installation time.
-
A wood-framed home in Repentigny needed reinforced wall mounts to prevent vibrations.
At AirGreen, we always conduct a personalized assessment and inform the client of the required timeline, technical challenges, and tailored solutions.
Lie #3: “The model I’m offering you is the best”
Many salespeople push just one wall-mounted air conditioner model—not because it’s the best, but because they have a deal with a supplier or inventory they need to move. They don’t take into account:
-
the required BTU capacity based on your home’s size and sunlight exposure,
-
your home’s layout,
-
your preferences (noise level, connectivity, design, etc.),
-
or the available grants linked to specific models.
At AirGreen, we don’t sell just one product—we recommend the best-fit solution after a full analysis of your needs. That’s why our customers in Longueuil, Saint-Jérôme, and Saint-Lambert refer us so often.
Lie #4: “Wall-mounted units don’t need maintenance”
This is one of the most dangerous lies. Even the best wall-mounted units need regular maintenance to:
-
prevent breakdowns,
-
maintain good energy performance,
-
eliminate bacteria and mold from filters,
-
and extend the unit’s lifespan.
At AirGreen, we offer a full HVAC maintenance service, including deep cleaning, filter disinfection, refrigerant line inspection, and outdoor unit checks. Many clients on the South Shore call us every spring for their annual maintenance.
Lie #5: “This unit is eligible for the grant”
Some salespeople promise government grants without confirming if the equipment is actually eligible. The result? The customer installs a unit expecting savings, only to find out later it doesn’t meet the energy efficiency criteria required by Hydro-Québec or the LogisVert program.
At AirGreen, we verify everything BEFORE the sale. We help you:
-
choose a certified eligible model,
-
prepare the required documents,
-
and submit the application to maximize your savings.
