Wall-mounted air conditioner installations are not always as perfect as one might hope. At AirGreen, we have seen a wide range of installations, some flawless, others… not so much. In this article, we reveal the 5 worst wall-mounted air conditioner installations we've encountered, complete with photos to help you understand the common mistakes and lessons learned. The goal is to help you avoid these pitfalls and ensure your installation goes smoothly, maximizing the efficiency of your air conditioning system.
Mistake #1: Installation Too Close to the Ceiling
One of the most common mistakes we encounter during wall-mounted air conditioner installations is the incorrect distance between the indoor unit and the ceiling. Installing an air conditioner too close to the ceiling can interfere with its efficiency. The airflow will be restricted, which leads to poor air circulation and reduces the performance of the air conditioner.
Real Example:
During an installation in Longueuil, the air conditioner was mounted too close to the ceiling, which resulted in ineffective cooling throughout the room. After a few weeks of use, the customer noticed a significant temperature difference, with areas near the unit being too cold, while spots farther away remained uncomfortably warm.
Tip:
When installing your wall-mounted air conditioner, make sure it's positioned at an adequate distance from the ceiling (generally between 5 and 10 cm) to allow for optimal air circulation.
Mistake #2: Incorrect Airflow Orientation
Proper positioning of the wall-mounted air conditioner is key to maximizing energy efficiency and ensuring even temperature distribution in the room. Unfortunately, some installations fail to account for the direction of airflow, which can result in uneven cooling or heating.
Real Example:
In an installation in Montreal, the air conditioner was positioned in such a way that the airflow blew directly onto a couch, creating extremely cold spots in certain parts of the living room. The customer complained about the discomfort caused by the direct cold air, and adjustments were made to reposition the unit to improve air distribution.
Tip:
Before installing a wall-mounted air conditioner, make sure to orient the unit strategically, avoiding directing the airflow directly onto seating areas such as couches or beds.
Mistake #3: Placement on a Weak Wall
While this may seem obvious, it's crucial to ensure the wall chosen for the air conditioner installation is sturdy enough to support the weight of the unit. We've seen many installations done on weak walls, which can lead to safety risks or structural damage.
Real Example:
In an installation in Laval, the air conditioner was mounted on an unreinforced plaster wall. Within a few months, the unit began to detach partially, creating a risk to the occupants of the home. The customer had to call in a professional to repair the wall and reposition the air conditioner on a more stable surface.
Tip:
Ensure the wall you choose is solid and suitable for mounting a wall-mounted air conditioner. If needed, opt for a reinforced metal bracket for added support.
Mistake #4: Improper Drainage of Condensed Water
Another common mistake is improper drainage of condensed water. A wall-mounted air conditioner produces moisture, and if this water is not properly drained, it can accumulate inside the unit, leading to leaks or even mold growth.
Real Example:
During an installation on the South Shore, the drainage system for condensed water was not correctly installed, causing water to accumulate inside the room. This led to floor damage and poor indoor air quality.
Tip:
Make sure your air conditioner's drainage system is installed properly, and that the water is directed to an appropriate location, such as outside the house or into a reservoir.
Mistake #5: Installation in a Poorly Ventilated Area
An installation in a poorly ventilated area is one of the most serious mistakes. A wall-mounted air conditioner, to function efficiently, requires proper air circulation, not only within the room but also around the outdoor unit. An installation in a poorly ventilated location can hinder the air conditioner's performance and cause overheating.
Real Example:
In an installation in Pierrefonds, the outdoor unit was placed near a wall and surrounded by vegetation, which reduced airflow. This led to the system overheating and a decrease in energy efficiency, as well as increased maintenance costs.
Tip:
When installing a wall-mounted air conditioner, make sure the outdoor unit has a clear, open space around it to allow for proper ventilation.
