These all rely on exterior vents to expel moist air, odors, and other byproducts from your home. Over time, these vents can become blocked by debris, damaged by weather, or even jammed open, leading to:

Pest Infestations: Open or damaged vents are like an open invitation for pests such as birds, rodents, and insects to make themselves at home in your ductwork. Once inside, they can cause extensive damage and create unsanitary conditions.

Increased Energy Costs: Vents that don’t close properly allow cold air to enter your home in the winter and hot air in the summer, forcing your HVAC system to work harder and driving up your energy bills.

Appliance Malfunctions: Blocked or obstructed vents can cause your bathroom fans, stove hoods, and air exchangers to function poorly, or even break down entirely. As one Calgary homeowner discovered, replacing the dryer didn’t solve the problem because the real issue was a blocked vent that needed cleaning.
