On the bright side, a Toronto ductless air conditioner is easier to hide than a window-type unit. The system comes in two separate components: an indoor cooling unit and an exterior condenser unit. The cooling unit doesn't stick out unlike a typical window-type AC, while the condenser unit can be hidden from plain sight.
Landscape expert Judy Weightman also suggests planting around the condenser unit to provide a sort of green camouflage. Some methods won't cost a cent, provided you already have potted plants in your home. However, it's best to take the heat emitted by the unit into account. After all, heat stress is just as harmful to plants as it is to humans.
