Gas vs. Wood: Key Inspection Differences
Gas fireplaces don't produce creosote, which is the primary concern with wood-burning systems. That said, gas combustion creates moisture and acidic condensate that gradually corrodes metal liners and deteriorates mortar from the inside out.
The bigger risk with gas systems is carbon monoxide. An undetected crack in the flue, a misaligned connector, or a bird nest blocking the terminal can send CO into your home silently. According to the Centers for Disease Control and Prevention (CDC), CO poisoning is responsible for more than 400 deaths in the US annually.
