A neglected wall-mounted air conditioner can quickly become a real threat to your health and the health of your loved ones. At AirGreen, we were recently called to a disturbing situation in the Rosemont–La Petite-Patrie borough of Montreal. A Fujitsu Halcyon 18000 BTU wall-mounted air conditioner, left without maintenance for several years, turned into a true health nightmare for a local family. Here is the detailed story of our intervention, a story that could help you avoid similar risks.
