Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Orland Park Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Orland Park, with typical installed pricing between $2,800 and $4,500 depending on liner diameter, height, and whether the existing liner is stainless or terracotta. Most Famco flue liner jobs we book in Orland Park are completed in a single day once the scope is confirmed. Homeowners usually discover the failure during a sweep when our camera spots cracked terracotta, gaps at the collar joint, or rust-through on an older stainless liner that was never rated for the appliance below it.

Which Famco Models This Applies To

Famco flue liners fall into two distinct product families, and mixing them up is the most common compatibility error we correct in Orland Park homes. The Famco stainless flexible liner series (typically 316Ti alloy, .006 to .012 wall thickness) was sold heavily between 2005 and 2018 through HVAC wholesalers serving the southwest Chicago suburbs. These carry a stamped collar label near the top termination, often weathered to near-illegibility after fifteen Illinois freeze-thaw cycles. The Famco rigid stainless line, less common here, uses segmented joints with a distinct double-wall configuration and was spec’d for some oil-to-gas conversions in Orland Park and Tinley Park around 2012 to 2016.

To identify what you have, we need three measurements: the flue’s inner diameter at the thimble, the total vertical run from appliance collar to termination, and the appliance type and BTU input. The OEM Famco part number, if readable, helps but is not required. We source replacement through Haven’s buying network from Famco direct, Olympia Chimney, and Copperfield, matching alloy grade and wall thickness to what was originally installed or upgrading where the original was underspec’d. An aftermarket 316Ti equivalent from Olympia Chimney often runs 15 to 20 percent below Famco OEM with identical warranty terms, and we quote both when the difference matters to the budget.

Signs Your Famco Flue Liner Replacement Is Failing

• White or orange staining on the chimney breast. This is chloride-induced corrosion on a stainless liner, accelerated by Orland Park’s wet shoulder seasons where the flue never fully dries between burns. The stain is salts leaching through masonry joints, and it means the liner wall is thinning from the outside in.
• Bits of terracotta in the cleanout or hearth. If your original was clay tile, spalling (surface flaking from freeze-thaw) sends shards down the flue. We see this most on north-facing chimneys in Orland Park, where the masonry stays cold and damp longest.
• Smoke rollout when opening the firebox door. A liner that has shifted at a joint, cracked, or partially collapsed creates a pressure disruption. The smoke follows the path of least resistance, which is now back into your living room instead of up the stack.
• A new appliance that “doesn’t draft right.” Famco liners installed for older, lower-efficiency furnaces are often 5-inch or 6-inch diameter. A modern 80,000 BTU unit may need 7-inch or larger. The mismatch shows up as condensation in the flue, rusted vent connectors, or a persistent sulfur smell.
• The camera shows a gap or shadow at the liner collar. During our NFPA 211 Level 2 inspection, we document this as a breach in the flue envelope. Combustion gases, including carbon monoxide, can enter the chimney cavity and from there the home’s framing or living spaces.

Replacement Cost & What’s Included

In Orland Park, a full Famco flue liner replacement runs $2,800 to $4,500 installed for a typical single-flue masonry chimney up to 25 feet. The range breaks down as follows:

What drives the upper end: taller chimneys (two-story Orland Park homes near Centennial Park with 35-foot runs), multiple flues, or the need to rebuild the top course or crown to get a proper seal. What we do not do: quote a low number, start work, then discover “unforeseen” conditions. Clause 1 of the Haven Standard requires a written price, written scope, and written warranty before anyone touches your chimney. The camera goes in first. The price comes after.

Every liner we install carries a lifetime warranty on materials and our 365-Day Done Right Promise on the workmanship. The photo record, Clause 4 of the Haven Standard, documents the full flue condition before and after.

DIY or Call Us?

There is exactly one safe DIY step here: look up your flue from the cleanout or firebox with a flashlight and note what you see. If the liner surface is continuous, uncracked, and free of rust flakes, you may simply need a sweep and inspection. If you see gaps, missing sections, or the liner has detached from the collar, stop there.

Flue liner replacement is not a homeowner project. The work involves working at height on a steep-pitch roof, handling sharp stainless edges, and properly sizing the liner to the appliance using NFPA 211 tables, not guesswork. An undersized or uninsulated liner in an Orland Park chimney will fail again, often within two seasons, because the flue gases cool too fast in our climate and condense into corrosive acids. Worse, a liner installed without proper collar sealing or support spacing can shift, creating the exact carbon monoxide path the replacement was meant to close. We are not affiliated with Famco; we are an independent service provider with the parts on our trucks and the camera documentation to prove the fix.

Call (708) 294-2571 when you’re ready for the inspection. We’ll show you the footage, write the price, and book the work only when the scope is clear to both of us.
