Gas furnace attic smell.
Sometimes when you first turn on the heater it can smell like gas is burning.
The first time your furnace is used in the winter when furnaces sit idle for months dust and debris build up.
This is normal but you can cut down on the duration of this unpleasant smell by opening some windows to allow for cross ventilation to dissipate the smell quickly.
If the smell isn t coming from the vents it s most likely a leak at a pipe fitting or within the equipment.
The smell of natural gas or propane gas around your gas furnace is not good.
When the furnace is turned on the dust gets burned off.

So before you call for hvac service look around and make sure you don t have a dead rodent in the attic somewhere.
This will most likely diagnose a leaking furnace heat exchanger.
