Furnace air intake vents are vulnerable to rodent and bird infestations. When animals make their nests inside your air intake vents, the end result is often furnace damage. Luckily, there's a simple way to prevent your furnace air intake vent from becoming a home to pests. These answers to frequently asked questions will teach you how to protect your furnace air intake vent.
What is the air intake vent?
The air intake vent for your furnace is a pipe that leads from the outside of your home to the furnace unit. Air intake vents supply the furnace with fresh air from outside the house.
Where is the air intake vent located?
Air intake vents are generally located on the side of the house. Air intake vents may be made of white plastic or black plastic, with a curved part that directs the opening toward the ground. Some air intake vents are flush against the house and the opening is protected by a slanted hood.
There are multiple pipes and vents on the side of the house. How can you identify the air intake vent?
When the furnace is turned on, there will be a breeze near the vent. Putting your hand against the opening, you should be able to feel the gentle whoosh of air as it enters the pipe. If you're still not sure which vent is the intake vent, a professional furnace repair person can identify your intake vent for you. When you identify the intake vent, you might see that there is already a screen fitted around the outside or placed on the inside of the vent. If this is the case, then your work is done. If the vent is open to the elements, however, then now is the time to install a screen yourself.
How can you protect the air intake vent from an infestation?
Depending on the size and type of intake vent, you may be able to find a screen made for intake vents of the type in your home. If you can't find a commercially made screen, the answer is simple. Buy galvanized wire mesh, then cut out the mesh to fit inside the pipe. Place the cut screen inside the air intake pipe. The sharp pointy edges of the mesh should poke into the insides of the pipe and help keep the screen in place inside the pipe.
