Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Las Vegas Owner’s Guide

We stock and install Famco-compatible flue liner replacement parts throughout Las Vegas, with most jobs running between $900 and $2,400 installed depending on the liner length, diameter, and whether we’re replacing the connector pipe too. The liner itself typically costs $35 to $65 per foot, and labor for a straightforward single-story replacement runs $450 to $800. Most owners discover the problem the same way: a chimney inspection flags cracks or separation in the liner, or the water heater starts venting poorly and the carbon monoxide detector picks it up. Either way, if you have a Famco liner that’s failed, we can get you sorted, usually within a day or two of the initial inspection.

Which Famco Models This Applies To

Famco makes flexible aluminum and stainless steel flue liners for gas appliances, plus rigid galvanized and stainless connector pipes. We see a lot of homeowners in Las Vegas with Famco’s aluminum flex liners on older furnaces and water heaters, particularly in homes built between 1985 and 2005. If you’ve got a Famco liner, the model number is usually printed on a label near the top or bottom collar, or stamped into the metal itself.

The compatibility gotcha with Famco liners is diameter matching. A 4-inch liner doesn’t swap for a 5-inch without modifying the appliance collar, and sneaking in a smaller diameter liner than the appliance requires is both a code violation and a carbon monoxide risk. We measure at the appliance outlet and at the termination cap, because sometimes the liner has been stepped down mid-run and the two ends don’t match. That’s a common find in older Las Vegas houses where handymen did retrofits without pulling permits.

On OEM versus aftermarket: Famco-branded liners are still made, but many of the aftermarket equivalents from companies like DuraFlex and Copperfield meet or exceed the original specs at a lower cost. We’ll give you both options with an honest recommendation. For gas appliance venting, a quality aftermarket liner with the right UL listing does the job just as well as the Famco original, and that’s what we stock on the truck most days.

Signs Your Famco Flue Liner Replacement Is Failing

• Soot streaks on the wall near the appliance. If the liner has separated at a seam, combustion gases leak into the chase and leave dark marks around the wall or ceiling near the flue path. This is the most common visual cue we see in Las Vegas homes with failed flex liners.
• A metallic rattling sound when the furnace kicks on. Aluminum flex liners expand and contract with heat cycling. When they’ve fatigued, the coil sections tap against each other or the chase walls. It sounds like a loose rain gutter in a light wind.
• Water staining at the base of the chimney or around the appliance vent. A cracked or separated liner lets condensation and rain in, and Las Vegas’s monsoon-season downpours find every seam that’s opened up.
• Pilot light or burner repeatedly going out. When a liner is blocked or collapsed, it starves the flame of combustion air. If you’re relighting a gas water heater every few weeks, the venting is the first place we check.
• Musty or exhaust-like smell near a gas appliance. Leaking flue gases have an acrid, spent smell that’s different from natural gas odorant. It means the liner is venting into the home instead of up and out. This one is urgent and you should call us right away.

Replacement Cost & What’s Included

In Las Vegas, a Famco flue liner replacement involving a single-story chase and a 15 to 25 foot run typically lands between $900 and $1,600. A two-story home or a liner that runs through an interior chase with restricted access usually comes in between $1,400 and $2,400. The liner material itself is the minority of cost. Most of the expense is in access, pull-out of the old liner, fabrication of the new one to length, and reconnection at both ends. We quote the full installed price, not a parts-only number that leaves you holding the ladder.

Here’s the breakdown we give every customer before we start:

• Famco-compatible flex liner: $35 to $65 per foot, depending on diameter and whether it’s aluminum or stainless
• Connector pipe, if needed: $40 to $90 per section
• Termination cap: $50 to $140
• Labor (single-story, standard access): $450 to $800
• Permit and inspection, when applicable: $75 to $180

Note on Las Vegas specifics: the Nevada Administrative Code requires gas appliance venting to meet the manufacturer’s installation requirements, and most single-family replacements qualify as a like-for-like swap that doesn’t need a permit. We’ll tell you if yours does.

Every replacement carries the 365-Day Done Right Promise. It’s a written guarantee, handed over with the invoice, and if the repair fails within the coverage period, we come back and fix it at no charge. No prorating, no arguing about what “covered” means. It’s one page, plain English, signed before you pay.

DIY or Call Us?

There’s a real safety concern here, so let me be direct: a flue liner carries carbon monoxide and other combustion gases out of your home. If a liner installation is done wrong, even slightly wrong, those gases can end up in your living room. Carbon monoxide has no smell and no color. That’s not a detail you want to get wrong on a Saturday afternoon with a YouTube tutorial.

What an owner can safely do is identify the problem. Check the visible connector pipe for rust blooms, separated joints, or soot marks. Look up the chase with a flashlight from below, if the appliance is accessible for that. That’s information gathering, and it’s useful when you call us because it tells us what to expect on the truck.

What an owner should not do is pull the old liner out of a second-story chase with a rope, or cut a new liner to length with tin snips, or connect a new liner to an appliance if you haven’t done at least a dozen before. We’ve seen DIY liner jobs in Summerlin, Henderson, and North Las Vegas where the liner was crimped shy of the collar and gases were venting into the attic. The homeowner saved $500 and created a hazard that took us half a day to correct. Call (725) 220-6109 and we’ll get you a straight quote first.
