When transparency is not always present in the HVAC sector
In the residential and commercial air conditioning installation industry in Montreal, Laval, Longueuil, the North Shore, and the South Shore, there are still practices that slip past the attention of customers. At AirGreen, we believe in complete transparency — but this is not always the case elsewhere. Here are five things that some installers might deliberately hide from you when installing your air conditioning system.
Cheap brands used instead of the advertised models
One of the most common practices, seen during several service calls in Laval and Longueuil, is replacing the wall-mounted air conditioner or heat pump model you were originally quoted for with a cheaper model from a lesser-known brand. Some unscrupulous contractors install a visually similar unit, but with lower-quality components and a shorter lifespan.
At AirGreen, every estimate specifies exactly the model, brand, and serial number of the system being installed — whether it’s a Fujitsu 12,000 BTU heat pump, a Bosch central unit, or a Gree multi-zone solution. We also provide you with the original warranty documents, no exceptions.
The real eligibility for rebates is not always disclosed
Many customers believe that an "energy-efficient" device is automatically eligible for Hydro-Québec’s LogisVert rebates, but it's not that simple. We’ve seen installations in Montreal and on the South Shore sold as eligible… when they did not meet the SEER standards or the program’s requirements.
A good installer will clearly explain:
-
The technical criteria for the program (SEER, HSPF, Energy Star).
-
The required documents for the application.
-
The payout timeline.
-
The exact amount you can receive (e.g., $1,704 or $2,172 depending on the BTU rating).
AirGreen assists its clients every step of the way, with compliance certifications for every project, whether it’s a downtown condo or a single-family home in Blainville.
Incorrect sizing to save time or unload stock
One of the most costly traps for customers is the installation of an improperly sized unit. Too powerful, it creates short cycles, consumes more energy, and wears out the compressor prematurely. Too small, it runs continuously without ever reaching the desired temperature.
We’ve reviewed several installations on the North Shore where an installer imposed a 24,000 BTU system in a space that only required an 18,000 BTU unit, simply to unload stock.
At AirGreen, every project undergoes precise thermal load calculations, taking into account:
-
The area to be cooled.
-
Existing insulation.
-
Sun exposure.
-
The number of floors and windows.
This step is essential to ensure efficiency, comfort, and longevity.
Hidden costs not outlined in the initial estimate
It’s common for some companies to intentionally omit mentioning:
-
Travel fees for areas outside Montreal’s central zone.
-
Fees for wall protection or external supports.
-
Costs for electrical connections if upgrades are needed.
-
Charges for removing old units.
We’ve seen in Laval and on the South Shore clients receive final invoices with over $500 in additional costs they had never approved.
At AirGreen, the price quoted is the final price. No surprise charges. Everything is clearly outlined from the initial estimate.
No follow-up after installation
Too often, once the installation is completed, the contractor disappears. However, an air conditioning system requires follow-up, regular maintenance, and sometimes adjustments.
Here’s what some installers neglect:
-
Performance checks one month after installation.
-
Filter cleaning during the first season.
-
Help with warranty registration.
-
Quick access to a technician in case of issues.
At AirGreen, we remain available after installation. Our clients in Montreal, Laval, or Longueuil can contact us 7 days a week for advice, maintenance, or quick intervention. This is what builds the lasting trust we maintain with our clientele.
