HVAC Installation Errors in Montreal: Why So Many Corrections by AirGreen?
At AirGreen, we are regularly called to intervene and correct air conditioning installations that were initially done by third parties. In fact, nearly 80% of the cases our technicians handle in Montreal, Laval, Longueuil, the North Shore, and the South Shore are related to avoidable mistakes made during the initial installation. Why does such a high percentage of installations require our specialists' intervention? Here, we reveal the main reasons and the solutions we provide.
The Most Common Errors Found in Air Conditioning Installations in Montreal and Surrounding Areas
Our AirGreen technicians often spot the same critical errors that directly affect comfort, energy costs, and the longevity of HVAC equipment:
Incorrect Sizing of Air Conditioners
The most frequent mistake our experts encounter is the wrong choice of air conditioner, particularly incorrect sizing in terms of BTU. An oversized air conditioner results in constant short cycles, causing premature wear of the equipment and an unnecessary increase in electricity bills. Conversely, an undersized air conditioner will fail to maintain optimal comfort.
At AirGreen, every HVAC installation is preceded by a rigorous analysis based on the exact area to be cooled, its orientation, thermal insulation, and the number of occupants.
Poor Placement of Units
Our interventions often reveal that wall-mounted air conditioners are placed in inappropriate spots: too exposed to the sun, too close to heat-producing appliances, or in areas that are not easily accessible for maintenance. This mistake significantly reduces energy efficiency and shortens the equipment's lifespan.
Our HVAC technicians ensure the optimal placement of each unit during every intervention, guaranteeing maximum performance.
Deficient Refrigerant Connections
Another major error is poorly executed refrigerant and electrical connections. Faulty connections lead to refrigerant losses, compromise the system's efficiency, and incur significant repair or maintenance costs.
During every installation or correction, AirGreen technicians ensure airtight and perfectly insulated connections.
Why Do These Mistakes Happen So Frequently in Montreal?
Several reasons explain why so many HVAC installations require correction by our specialized technicians:
Use of Non-Specialized Installers
Many homeowners opt for general contractors or non-certified installers to save money upfront. However, this choice often proves to be costly in the long run, as non-compliant installations lead to repeated interventions, higher energy costs, and reduced equipment lifespan.
At AirGreen, all our technicians are specialized and guarantee the flawless quality of every installation.
Neglecting Proper Site Preparation
Many installations performed by third parties are done without a thorough site analysis. An air conditioning installation requires careful preparation, taking into account the technical specifics of the building and the real cooling needs.
Every AirGreen intervention is preceded by a comprehensive technical evaluation, ensuring a perfect match with the building's actual conditions.
Real-Life AirGreen Intervention: Correcting a Faulty Installation in Longueuil
Recently, our AirGreen technicians were called to Longueuil to correct a Fujitsu 24,000 BTU wall-mounted air conditioner installation, which had been performed six months prior by a non-certified provider. The client complained of poor performance, excessive energy bills, and ongoing discomfort.
After a thorough inspection, our experts identified three major errors:
-
Poor placement of the outdoor unit, exposed to direct sunlight, causing constant overheating.
-
Incorrect sizing with a unit that was too powerful for the real needs of the house.
-
Insufficient insulation of the refrigerant lines, leading to significant energy losses.
Our technicians repositioned the outdoor unit, added professional-grade insulation, and replaced the air conditioner with a properly sized Fujitsu 18,000 BTU unit, precisely matched to the house's square footage. Immediately after the work was completed, the client noticed a significant improvement in both comfort and energy consumption.
