Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Los Angeles Owner’s Guide

We stock and install Famco-compatible flue liner replacement parts across Los Angeles, with most complete liner swaps running $1,800 to $3,400 installed depending on flue length, diameter, and access. A simple Famco connector or adapter replacement is usually $300 to $650. Most homeowners discover the problem the same way: a Level 2 camera inspection after noticing a smell, visible flaking, or water staining near the chimney chase.

Here’s what the page covers: which Famco models this applies to, what fails first, what a replacement actually costs, and how Hank Delano and the Flint Chimney Sweep crew approach this job. If you already know your Famco model number, that helps. If you don’t, we’ll identify it off the tag or by measuring the inside diameter during the service call.

Key takeaways:

• Famco flue liner replacement in Los Angeles typically costs $1,800-$3,400 installed for a full reline; $300-$650 for a connector or adapter only.
• We stock Famco-compatible connectors and adapters on the truck; full liner kits are ordered per-job by exact diameter and length.
• Every replacement carries the 365-Day Done Right Promise in writing before the work begins.
• We are an independent service provider, not affiliated with Famco. You’re getting honest compatibility guidance, not a brand pitch.

Which Famco Models This Applies To

Famco makes venting and connector components more than complete liner systems, so the typical Los Angeles home needs a Famco connector or collar replacement rather than a full Famco-brand liner. The most common Famco parts we replace are the 4-inch, 5-inch, 6-inch, 7-inch, and 8-inch round chimney connectors, adjustable elbows, and appliance adapters used to transition from a furnace, water heater, or boiler into the flue chase.

The compatibility gotcha that trips people up: Famco connectors are sized by inside diameter, not outside diameter. A 6-inch Famco connector slides inside a 6-inch flue tile or liner, which means outside diameter runs about 6-1/4 to 6-3/8 inches depending on gauge. Homeowners who measure the wrong way end up ordering a connector one size off. We measure on site with calipers and confirm against the existing Famco tag when the label is still legible.

For full relines on Famco-equipped systems, we don’t force a Famco-brand liner. We specify whatever the flue actually requires: DuraFlex, HeatShield, or Gelco liners matched to the existing Famco connector footprint. The honest answer is that Famco connectors are excellent, and aftermarket or other-brand liners are entirely appropriate behind them when they meet UL 1777 for the application. On older furnaces and water heaters sharing one flue, we also check local Los Angeles code requirements for common venting versus separate liners, because LA County often requires the upgrade when both appliances share a single masonry chase.

Signs Your Famco Flue Liner Replacement Is Failing

Most Famco connector failures announce themselves slowly. Here’s what we actually see on service calls across Los Angeles, from Eagle Rock to the Valley:

• Rust staining or flaking metal at the connector seam. Condensation from high-efficiency appliances attacks galvanized steel connectors from the inside out. By the time you see rust rings, the connector wall is often paper-thin at the seam.
• A persistent metallic or exhaust smell near the utility closet or basement. This signals a failed seal or a pinhole leak in the Famco connector. Exhaust gases are escaping into living space, which is why we treat this as a priority call.
• Visible gaps or sagging at the appliance collar. The thin gauge metal expands and contracts with every heating cycle, and over 15-20 years the collar can pull away from the appliance outlet entirely.
• Water staining on drywall or framing near the chimney chase. In Los Angeles, this is often driven by winter rain plus a failed top plate or storm collar rather than the connector itself, but a camera inspection tells us which.
• The gas appliance won’t stay lit or the CO monitor is triggering. If the connector has collapsed or separated, draft fails. The appliance’s safety shutoff takes over. This is not a “wait and see” situation.

Replacement Cost & What’s Included

In Los Angeles, the installed range for a Famco flue connector replacement is $300 to $650, including the part, the site visit, and the labor to remove the old connector, seat the new one, and seal the joints with high-temp silicone rated for 500°F or better. A full flue liner replacement (mentioned above) runs $1,800 to $3,400, with the range driven by flue length, roof pitch and access, whether scaffolding is needed for a two-story chase, and liner diameter.

Here’s the Flint Chimney Sweep difference on any Famco job: you get a written price before any work starts. The number we hand you is the number you approve. Parts and labor are line-itemed. Every repair carries the 365-Day Done Right Promise in writing. If the replacement fails within one full year of the service date, we return at no charge. That’s not a verbal assurance; it’s the Garrison Standard, the code every Garrison Partners location operates under.

DIY or Call Us?

What you can safely do yourself: locate the Famco tag, note the model number and diameter if visible, and take photos of any rust staining or visible sagging at the connector. That information saves us a trip or helps us bring the right part on the first visit.

What you should not do: uncouple or replace a connector on a running gas appliance. You are working within inches of exhaust gases that can contain carbon monoxide, and if the draft fails after you disturb the joint, you’ve created a hazard you might not notice until symptoms appear. This is genuinely dangerous work when done wrong. Connector replacement also involves clearance-to-combustibles checks and proper support spacing that most homeowners don’t know to look for. If you’re in Los Angeles and your Famco connector is failing, call (830) 251-4560. We’ll give you a straight answer and a written price, and if it’s not a priority, we’ll tell you that too.
