Since no one here can smell it, it would be a wise move to locate a local
tech that can look it over, and insure you have no problems with the unit.

The typical smell that you get from the first fire of the season is nothing
but a little dust burning off the heat exchanger, or heat elements in the
case of a heat pump or electric unit...
Now..
You MIGHT have a condition known as DSS...or dirty sock syndrome...it
actually involves the AC coil

At night we turn the furnace down to 55 and in the morning turn it back up
to 70. Every morning there is a distinct odor when the furnace first
kicks
in. We've cleaned the burners to no avail. This doesn't happen when just
the fan is turned on, only when the burners ignite.
Any ideas?
