This page is for New York homeowners who own a Gelco gas or wood-burning fireplace and want straight answers about repair costs, parts, and whether the unit is worth saving. As an independent Gelco service provider, we’re not tied to the manufacturer’s warranty department or their parts pricing. We fix what’s broken and tell you honestly when it isn’t worth fixing.

How Gelco Products Fail – and How We Fix Them

Gelco built a lot of gas fireplaces and inserts in the 1990s and early 2000s, and we see the same failure patterns repeat across New York apartments and brownstones. Here’s what actually goes wrong:

  • Gelco direct-vent gas fireplaces: pilot light won’t stay lit. This is the most common call we get. The thermocouple or thermopile wears out, and the gas valve shuts down as a safety response. In New York, where many units run hard from November through March, these components fail faster than the manufacturer’s estimated lifespan. We test the millivolt output first, then replace the failing component with an OEM or equal-spec part rather than guessing.
  • Vent-free Gelco units: soot buildup on logs and glass. Vent-free burners are sensitive to dust, pet hair, and the dry air of radiator-heated apartments. When the burner ports clog, combustion gets dirty and soot deposits form on the logs and glass. We’ve seen units in Upper West Side co-ops where the glass was so coated the flame was invisible. The fix is a full burner cleaning, port clearing, and a fresh log set if the original ceramic logs have degraded.
  • Older Gelco wood-burning fireplaces: failed dampers and warped frames. Gelco’s steel fireboxes are durable, but the damper assemblies were a weak point. Years of heat cycles warp the frame, and the damper stops sealing. That means cold air pours down the flue all winter and your heating bill climbs. We replace the damper assembly or install a top-sealing damper, depending on what the existing chimney will accommodate.
  • Gelco fireplace inserts: blower motor failure. The blower motors on Gelco inserts are not available through the manufacturer anymore on many older models. We source compatibility-matched replacements from our chimney-trade suppliers, and we tell you before ordering if the motor is worth replacing or if the insert has reached the point where replacement makes more sense.
  • Burner pan corrosion on coastal-adjacent buildings. In neighborhoods near the harbor, salt air accelerates burner pan corrosion. A rusted burner pan produces uneven flames and can eventually leak gas. We replace the pan and burner assembly when we find this, and we always check for it during service because it’s common enough in New York’s older masonry buildings that we expect to see it on units older than fifteen years.

Our Gelco Fireplace Repair Process

Here’s what a Gelco repair call looks like from start to finish:

  1. 1
    You call, a person answers. No voicemail trees, no callbacks. We ask what the fireplace is doing, get the model number if you can find it, and book a window that works.
  2. 2
    We arrive in the window. Background-checked, uniformed, and in a marked vehicle. We’ll look at the unit, check the gas line and venting, and run the diagnostics on the spot.
  3. 3
    We give you a written price before any work starts. That price covers parts and labor. If we find something else once we’re into the repair, we stop and show you what we found before spending another dollar.
  4. 4
    We do the repair. For a Gelco job, that usually means replacing the failed component, cleaning the burner and pilot assembly, verifying gas pressure, and checking the venting for obstructions or corrosion.
  5. 5
    We test everything while you watch. We want you to see the flame burning clean and the pilot holding. If it doesn’t hold, we’re not done.
  6. 6
    You get a written guarantee. Every Gelco repair comes with our written warranty. If it fails inside the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s not an upsell.

Why New York Homeowners Call Ashby Chimney New York for Gelco Work

We’ve been doing this since 2002, and Nathan Corliss has spent years inside New York flues from Inwood prewars to Upper West Side brownstones. That matters on a Gelco job because knowing the unit’s history is half the repair. We also stock and work with the chimney-trade brands that overlap with Gelco systems: DuraFlex liners and HeatShield resurfacing material, so if your fireplace repair turns up a chimney issue too, we can handle it in the same visit with materials we trust.

The Kingswell Way is simple: say the price first, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails. Ashby carries ash right in the name, fitting for the people whose job is to clean it out.
