Some parts of gas fireplace cleaning are safe for a homeowner to handle. The glass, for example, can be cleaned with a fireplace-rated glass cleaner and a soft cloth, as long as the unit is completely cold and the gas is off. Vacuuming dust from the firebox interior is also reasonable if you're careful around the pilot and burner components. What you shouldn't do yourself is adjust gas pressure, disassemble the valve, clean inside the burner ports with anything that could leave residue, or touch the thermocouple connections without knowing how the safety circuit works. Those aren't intimidating jobs for a technician, but they're the kind of thing that goes wrong quietly when a homeowner takes a guess. If you're unsure where the line is, call us. We'll tell you straight. And if it turns out your unit just needs a glass cleaning and a log repositioning, we'll say that too. We're not going to invent a problem. That's not how we work, and it's not why homeowners across the metro keep calling us back.
