Homeowner’s Guide to Buying a Furnace Vent Pipe

You may know what a furnace vent pipe is, but have you ever heard of a furnace air duct? The term “vent” refers to the open end of the pipe, while the term “duct” refers to the shut end. The unit itself does not have a hose or clamps, however, the duct pipes do and this is where you are going to need to focus your attention.

Inside of your furnace are actually two sections; the first is called the compressor section and the second is the exhaust section. The compressor section of the furnace will have a hose leading into it and there will be some external hoses leading to the exhaust as well. Both of these pipes should be covered in rubber to keep moisture from building up inside them. If either of these parts become clogged, it can cause the entire unit to malfunction, so taking care of these parts is critical.

After the pipes are cleaned and serviced, you will need to remove the insulation from both of the vents, then attach the new air duct to the inlet on your furnace. Make sure you install the proper flange at the top and bottom of the air duct. This is the part that will keep the duct from blowing out during a cold winter. Once this is done, you can use a special brush to clean off any dirt or debris that may have been on the duct pipe before installation. When you are done, ensure that you check for any leaks and correct them if necessary.
