Gas Fireplace Diagnostic

Pilot won't stay lit. Remote does nothing. Burner lights, then drops out ten minutes later. Glass fogs over with a white film. From your side of the room these all look the same, and they have completely different causes: a dirty thermopile, a failed thermocouple, a weak millivolt signal, a blocked venturi, a bad receiver module. This visit is the finding, not the fixing. We test gas pressure and millivolt output, inspect the burner, pilot assembly, and venting, and tell you exactly what's wrong and what it costs to put right. Approve the repair and the diagnostic fee comes off the bill. Gas work is performed or signed off by a licensed professional, to the code in force where you live.

  • Diagnostic fee credited when you approve the repair

Scoped from a graded inspection

At PCS Services, a gas fireplace diagnostic is never guesswork. We scope every job from a graded, photographed inspection first — the NFPA 211 level the evidence calls for — so the work is matched to what your flue and masonry actually need, with the report to prove it. The documented inspection is the record the gas fireplace diagnostic is built on.

FAQ

Common questions about gas fireplace diagnostic.

What's actually included in the annual plan?

One full visit a year: a complete sweep, a top-to-bottom inspection, and a photo report you keep. Between visits you get the part you can't see — we track your schedule, send the reminders, and hold priority slots for plan members during the fall rush. If a repair ever comes up, you get a written quote first. There's no contract; the plan renews only if you want it to.

How do the reminders work?

Before we leave your first visit, next year's window goes on our calendar. When it gets close, we reach out — text or call, your choice — and you pick the exact day. If you don't answer, we try again. That's the entire trick of the plan: your chimney gets maintained because someone whose job it is remembered, not because you happened to.

Is a maintenance plan worth it for every home?

Honestly, no. If your chimney was built or fully relined in the past year, wait — it doesn't need a plan yet, and we'd rather tell you that than sell you one. Same if you have a gas-only fireplace you light twice a winter: an inspection every year or two covers you. Plans earn their keep for wood burners and busy households. On the fence? Ask. We'll tell you straight.

When should I book my yearly sweep?

Late spring through summer is the smart window. The chimney's done for the season, everything winter did to it is visible, and appointments are easy to get. Most people call in October instead, when the calendar's slammed and the first cold front is a week away. Either works. But book in June and you'll never think about it in October.

Why is fall such a rush?

Because the first cold snap is the chimney trade's alarm clock. From September through November, everyone who forgot their fireplace all year remembers it in the same two weeks, and every sweep in Dallas–Fort Worth is booked solid. It's the worst time to need an appointment, and it's the whole reason our plans schedule you automatically before the crowd shows up.
