The Unknown Risks of an Improperly Sized Air Conditioner in Montréal
In Montréal, indoor comfort is crucial, especially during hot and humid summers. However, a common trap threatens the well-being of many households and businesses: the installation of an improperly sized air conditioner. At AirGreen, we frequently encounter the disastrous consequences of this common issue. In this article, we share our expertise to help you identify, understand, and, most importantly, avoid this frequent pitfall in HVAC installations in Montréal, Laval, Longueuil, and on the North and South Shores.
Practical Consequences of an Improperly Sized Unit in Montréal
Choosing the right power for a wall-mounted air conditioner or a heat pump is not just a technical formality. An improperly sized system leads to real problems that we often see in our clients' homes:
Excessive Energy Consumption
An oversized air conditioner constantly cycles on and off, wasting energy unnecessarily. On the other hand, an undersized unit has to run continuously, leading to astronomical energy bills. Recently, at a client’s home in Longueuil, we observed a 35% reduction in energy costs after replacing their improperly sized unit with a properly sized Fujitsu model.
Persistent Thermal Discomfort
An improperly sized unit struggles to maintain a constant temperature. You’ll experience alternating hot and cold, significantly reducing your comfort. In Laval, a family dealt with this issue for years before AirGreen stepped in and installed a correctly sized Bosch BIVA IDS Premium heat pump, finally bringing stable comfort.
Premature Wear and Increased Maintenance Costs
An inadequate air conditioner wears out prematurely, increasing repair costs. In Montréal, we've had to replace compressors early in several clients' systems, whose initial installations were improperly sized by other contractors.
How AirGreen Avoids the Pitfall of Improper Sizing in Montréal
At AirGreen, every HVAC project begins with a precise and detailed diagnosis. Here’s our unique process that ensures perfectly sized installations:
Thorough Analysis of the Building and Specific Needs
Our specialized technicians carefully analyze every detail of your home or commercial space:
-
Exact surface area of the rooms to be cooled.

Sun exposure and wall insulation.

Number and size of windows.

Presence of heat-generating appliances or electronics.
This detailed approach allowed a commercial client on the North Shore to save $2,200 annually simply through the precise sizing conducted by AirGreen.
Rigorous Selection of HVAC Equipment
Based on the results obtained, we carefully select the brand, model, and exact power required. Among our preferred choices, we often recommend:
-
Fujitsu KZAH wall-mounted heat pumps (9,000 to 24,000 BTU).
-
Gree Sapphire or Bosch BIVA IDS Premium wall-mounted air conditioners.
-
Units using eco-friendly refrigerants such as R-32 or R-454B to maximize energy efficiency while reducing environmental impact.
Installation and Meticulous Follow-Up by AirGreen in Montréal
Our intervention doesn't stop with equipment selection. Proper installation is key to maximizing performance:
Installation by Certified Experts
Our teams in Montréal, Laval, and Longueuil are trained to ensure optimal installation, guaranteeing your air conditioner operates at its best. During a recent installation on the South Shore, our team faced a significant challenge related to poor insulation in an older home. Thanks to precise technical adjustments, we ensured the air conditioner operated perfectly and efficiently.
Regular Preventive Maintenance
At AirGreen, we always offer a regular maintenance plan to prevent any performance or consumption issues. This has saved several clients in Montréal from costly repairs by anticipating potential failures.
Real Example: How AirGreen Corrected a Common Mistake in Laval
Recently, in Laval, we were called by a homeowner frustrated by a wall-mounted air conditioner that, despite being relatively new, couldn’t maintain a stable temperature. After diagnosis, our team discovered that the unit, a 24,000 BTU Gree Extreme heat pump, was actually vastly oversized for the space it was cooling.
We recommended and installed a properly sized 18,000 BTU Bosch BIVA IDS Premium R-454B heat pump instead. The result? Immediate 40% energy savings, optimal comfort, and a significant reduction in noise. Our client now regularly praises their experience, clearly demonstrating the value of precise sizing.
Common Mistakes to Absolutely Avoid in Montréal
To help you avoid this common pitfall, here are the sizing mistakes to avoid:
-
Choosing power based solely on square footage, without considering insulation, orientation, and number of occupants.
-
Thinking a more powerful unit is always better, when it may end up wasting energy and reducing your comfort.
-
Neglecting the importance of a comprehensive professional diagnostic before any HVAC installation.
