What is a Furnace Flue Liner?

A furnace flue liner is an essential component of your home’s heating
system, responsible for safely venting hazardous byproducts of
combustion, such as carbon monoxide, out of your home. When you burn oil
or gas fuels to heat your home, these dangerous chemicals need a secure
pathway to escape, and that’s where your furnace flue liner comes in.
This vent creates a channel for these hot gases to be removed safely
from your living space.

Over time, your chimney flue can become damaged due to various factors,
including a lack of regular maintenance or excessive moisture exposure.
Most furnace chimneys are lined with terracotta clay flue liners, which
can be particularly vulnerable to the condensation emitted by modern
high-efficiency furnaces. If these liners are not properly maintained or
if they deteriorate, it can compromise the safety of your home by
allowing harmful gases to leak into your living spaces.
