The Incredible Story of a Wall-Mounted Air Conditioner Found Filled with Mold After a Summer in Laval (Real Testimonial)

How Poor Installation in Laval Led to a Concerning Mold Infestation in a Wall-Mounted Air Conditioner

When a wall-mounted air conditioner is installed correctly, it significantly enhances indoor comfort by providing optimal thermal comfort. However, at AirGreen, HVAC installation specialists in Laval, we have occasionally witnessed disastrous consequences stemming from sloppy installations. A particularly striking case, which recently occurred in Laval, shows just how poorly done installations can lead to major health and safety issues.

Real Testimonial: A Summer Ruined in Laval by a Mold-Infested Wall-Mounted Air Conditioner

At the end of last summer, we received an urgent call from the Beaulieu family, residing in the Vimont area of Laval. They had noticed a strange and persistent odor coming from their wall-mounted air conditioner, a popular Gree Extreme 18,000 BTU model that had been installed only three months prior by an unscrupulous company.

When our AirGreen team arrived, the discovery was shocking: the inside of the unit was completely overrun with thick black and green mold, contaminating the indoor air in a concerning way. After a thorough diagnosis, the root cause of the problem was clear: a series of avoidable installation errors.

Critical Errors That Led to Mold Contamination in This Wall-Mounted Air Conditioner in Laval

Our expertise allowed us to immediately pinpoint the mistakes made by the initial installer, each one directly contributing to the mold infestation:

  • Incorrect slope of the condensation drain: A misdirected pipe prevented the normal flow of condensed water, causing permanent stagnation inside the unit.

  • Failure to perform initial cleaning: The installer neglected to properly sanitize the internal components, allowing organic debris and impurities to foster rapid mold growth.

  • Inadequate thermal insulation: Insufficient insulation of the refrigerant pipes caused excessive condensation inside the wall-mounted air conditioner, exacerbating the issue.

  • Use of a low-quality air filter: The unit was equipped with a non-compliant filter that was unable to effectively capture mold spores and contaminants.

What Were the Health and Comfort Consequences for the Occupants in Laval?

The mold infestation inside this wall-mounted air conditioner did not just result in a bad smell: it had a real impact on the health and well-being of the Beaulieu family. Here are the symptoms observed in the residents during the weeks following the installation:

  • Persistent respiratory issues in the children.

  • Frequent, unexplained headaches.

  • Repeated skin irritations and allergies.

These symptoms significantly diminished shortly after our intervention, clearly proving the connection between the contamination and the health problems encountered.

Steps Taken by AirGreen to Resolve the Issue in Laval

Faced with such a situation, our team immediately took the following actions to restore a safe and healthy environment in the home:

  1. Immediate shut-off and complete power-down of the wall-mounted air conditioner.

  2. Thorough cleaning with professional antifungal products to completely eliminate mold and residual spores.

  3. Correct realignment of the drainage pipe to ensure optimal and continuous flow of condensed water.

  4. Replacement of the inadequate filter with an original certified model from the Gree manufacturer, ensuring optimal air filtration.

  5. Full re-insulation of the refrigerant pipes to prevent any further excessive internal condensation.

Thanks to these precise interventions, the Beaulieu family now enjoys a healthy, efficient, and safe wall-mounted air conditioner.
