Does Your Furnace Flue Need To Be Replaced?

Have you noticed your home isn’t heating as well as it once did? It may be time to check your furnace flue.

Your furnace flue is an exhaust stack, which vents carbon monoxide safely away from the inside of your home. It’s made from galvanized metal, which can rust and corrode over time.

When’s the last time you looked at your furnace flue? If you notice rust forming, it could be a sign that it's time to replace your furnace flue. If ignored, it can put your home at risk of leaking smoke and other dangerous chemicals back inside your home.Does Your Furnace Flue Need To Be Replaced?

Keep in mind that damage isn’t always visible from the ground. Even leaning a ladder against your home to gain a better perspective might not tell you all you need to know. Like other home maintenance projects, your flue should be cleaned and inspected annually to ensure it’s in good working condition. You should also have it cleaned and checked if you’re moving into a new home to ensure it was installed properly, or if you are moving into to new-to-you home to make sure it’s still in good shape.

In addition to normal wear and tear, other things can impact your furnace flue:

  • Weather
  • Tree limbs
  • Bird’s nest
  • Debris

Among other things.

It’s important to examine the entire length of the furnace flue. Pay attention to the seals around the rain cap, and the storm collar that fits directly into the roof. Look for damage, cracking, rust, or anything that looks suspicious. Because this can contaminate your air supply, err on the side of safety. Have a professional check out anything that looks suspicious.
