Yearly Gas Fireplace Service, Done Before It Turns Cool

The service exists because a gas fireplace in the Phoenix area keeps a strange calendar. NWS Phoenix counts an average of 111 days a year at 100°F or more, and Sky Harbor sees about one freezing night a year. So the fireplace runs a few dozen evenings in the cool months, then sits closed up through the hottest stretch of the year. Parts wear less from use than from that long, hot rest, and what they collect is small and easy to catch early: a dusty pilot hood, a log that has shifted, a glass gasket that has gone stiff, a receiver battery that leaked.

We do the service on a lit fireplace. You see the flame before and after, and you get photos of what we cleaned and anything we did not like the look of. The service is priced at the inspection, which is free, and any part that turns out to need replacing is priced separately on the same sheet before we fit it. Nothing gets added after the fact.

Signs you need this

• More than a year since anyone opened up the fireplace
• The flame looks different from how it looked last winter
• You bought the house and know nothing about the fireplace's history
• A smell on the first burn of the season that doesn't fade
• Rust, dust or debris in the firebox or on the logs

How we do it

1. Check before cleaningWe light the unit as it is and note the pilot shape, burner pattern, flame color and how quickly the burner comes up.
2. Shut off and open upGas off at the fireplace valve, glass or screen removed, logs lifted out and laid on a drop cloth in their order.
3. Clean and inspectBurner ports, pilot hood, thermocouple or flame sensor, ember bed, log surfaces, glass and gasket, plus the vent cap from outside.
4. Rebuild and burnLogs go back where the manual places them, glass is resealed, and the unit runs while we check flame, draft and the fittings we opened.

What is included in a gas fireplace service?

Inside the firebox we vacuum and brush the burner, clear the pilot hood and orifice area, and clean the thermocouple or flame sensor so it reads properly. The logs come out, get checked for cracks and heavy soot, and go back in the layout the manufacturer shows, because a log moved an inch can put flame where soot builds. Ember material is refreshed or reset over the burner ports.

On glass-front units we clean the glass, check the gasket all the way around, and look at the latches that hold the frame tight. Outside we look at the vent termination on the wall, or the cap on the stucco chase, for nests, damage or debris. Remote batteries and the receiver get checked too.

• Burner and pilot cleaned
• Thermocouple, thermopile or flame sensor checked
• Logs and embers reset to the manual's layout
• Glass, gasket and latches checked
• Vent termination or chase cap looked at from outside
• Test burn and leak check at every fitting we opened

Why book it in October rather than December?

The average last 100°F day at Sky Harbor is October 5. A few weeks after that, the first cool evenings arrive and gas fireplace calls pile up, and a service booked after Thanksgiving often turns into a repair visit. Doing it in October means a worn part can be ordered and fitted before you actually want the fireplace.

Booking runs Sunday through Friday in 3-hour windows, 8 to 11, 11 to 2 or 2 to 5, and we call to confirm before we come.

Does a fireplace used only on No Burn Days still need a service?

Gas is exempt from Maricopa County's No Burn Day rule, so plenty of people light their gas fireplace on exactly the nights the county bans wood. Those restrictions are declared mostly in the cooler months, often around the holidays, which is when you least want the fireplace to quit. Light use does not keep a unit clean; dust settles whether it runs or not.

If your home is in San Tan Valley, Maricopa or most of Apache Junction, you are in Pinal County, which runs its own air-quality program, so check its rules for wood fires. The gas fireplace service is the same either way.
