steam or smoke coming from my chimney only

I was driving around today (it's cold) and noticed that everyone else's chimney in the area was not putting out any visible gas. I presume that since its cold many people have their heat on (mostly gas). However, my chimney, when the furnace is on, puts out either smoke or steam.

I'm thinking that this might be a problem since we seem to be the only ones with that issue. Does anyone have any insight into that?

How old is your furnace?

Older equipment dumps hotter gasses into a chimney, while newer high efficiency furnaces condense the steam into water, recovering the energy produced by that latent heat.

No steam.

It was installed in 2005. Has efficiency improved that much since then?

You presumably have an 80% efficient furnace that uses metal vent pipe.


Also available are 90% plus efficient furnaces that often vent out the sidewall of a house using white PVC plastic pipe.

I too have noticed the same thing today, it is just abouve 20 degrees in NOVA today!

Does anyone know what it could be, should i be worried? We have an older burner probably from the 90's?

Any help appreciated

I drove past about 100 houses this morning and only saw two that had any steam/smoke coming out of them. In a neighborhood with houses as old as 60+ years, I find it hard to believe that they all have 90%+ efficient furnaces.

What am I missing here? I'm worried that there's something wrong with ours.

Steam

There are many factors including size & location (interior vs exterior) of the chimney, how long the furnace has been running, material of which the chimney is made, etc, etc, etc,. You seem to be worried so, the best advice any of us can give you is to call a service person & have your furnace checked out.
