When I light my fireplace I can sometimes (not always) hear a hissing sound.  The wood is dry and the flue is fully open.  What could it be?
How often should I get my chimney inspected and cleaned?
The frequency of chimney inspections and cleanings depends on how much you use your fireplace. As a general rule of thumb, it is recommended to have your chimney inspected and cleaned at least once a year to ensure it is functioning safely and efficiently.
