At a recent home inspection in Anacortes on Fidalgo Island, I discovered a gas fireplace clearly due for servicing and cleaning. When you begin to see a white, brown or black film beginning to present on the glass front of the fireplace, that’s your first sign that the appliance is due for servicing. As the video explains, it is highly recommended that you hire a professional to do so because if it’s not done properly, you risk carbon monoxide entering the home and soot byproducts outlining the ceiling and wall studs in the home. Manufacturers typically advise servicing annually.
