Don't wait for something to break. Here are the warning signs that your gas fireplace is overdue for gas fireplace cleaning or a fireplace inspection:
The Pilot Light Is Unreliable
If your pilot light goes out more than once a season, or if it takes multiple attempts to light and stay lit, something needs attention. It could be a dirty pilot orifice, a weakening thermocouple, or a draft issue. Any of these are quick fixes during a service visit — but if ignored, they'll eventually leave you with no fire at all.
You're Seeing Soot on the Glass
A properly tuned gas fireplace produces very little soot. If the inside of your glass is turning black or developing a heavy white film, the air-to-fuel ratio is off. This means incomplete combustion, which wastes gas and can produce carbon monoxide. This is one you shouldn't put off.
The Flames Look Different
If your flames are shorter than they used to be, burning unevenly, or have turned from blue-yellow to mostly orange, the burner likely needs cleaning. Clogged burner ports restrict gas flow and change the flame pattern. It's a common issue after a couple of seasons and usually takes us about 15 minutes to resolve.
Strange Smells
A faint smell during the first burn of the season is normal — it's just dust burning off. But persistent odors, especially anything that smells like rotten eggs (the additive in natural gas), means you should turn off the fireplace and call us immediately. We'll do a thorough gas leak inspection and make sure everything's safe.
It's Been More Than 12 Months
Even if everything seems fine, annual gas fireplace service is cheap insurance. The best time to schedule is in the spring, right after heating season ends. Everything gets cleaned and inspected while it's fresh, and you're ready to go when October rolls around. If you wait until fall, every fireplace tech in Denver is booked solid.
