Most U.S. homeowners pay $500-$3,500 to install or replace a gas furnace chimney liner depending on material, chimney height, and access. This gas furnace chimney liner cost overview shows low-average-high ranges and the main drivers that change a final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic aluminum liner (small, straight) | $300 | $700 | $1,200 | Assumptions: 10-15 ft, 1-2 elbows, easy access. |
| Stainless steel liner (class A, single appliance) | $600 | $1,400 | $3,000 | Assumptions: 15-25 ft, 2 elbows, mid-range labor. |
| Full relining (multi-appliance, tall chimney) | $1,500 | $2,800 | $5,500 | Assumptions: >25 ft, complex runs, permits. |
Typical Price To Install A Chimney Liner For A Gas Furnace
Expect a typical total price of $700-$1,800 for a single gas furnace when using stainless or aluminum liners. Lower-cost jobs use aluminum or flexible liners under 15 feet; average jobs use 24-gauge stainless for 15-25 feet; high-end jobs use thicker stainless, long runs, or require masonry work. Assumptions: single-family home, one appliance, normal access, no structural repairs.
Breakdown Of Materials, Labor, Equipment, And Permits
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $200-$1,200 (aluminum $150-$500, stainless $400-$1,200) | $300-$1,200 (2-8 hours × $75-$150/hr) | $50-$400 (scaffolding, winches, vacuum) | $0-$300 (local code, inspection fees) | $0-$150 (old liner removal, cleanout) |
Materials and labor are the biggest line items; expect materials to be 30%-60% of the quote depending on liner type.
How Chimney Height, Number Of Elbows, And Liner Material Affect Price
Chimney height and bends are primary cost multipliers: each additional 5-10 ft or elbow typically adds $75-$250. Examples: straight 12-15 ft run = base cost; 20-30 ft run adds $300-$800; runs with 3+ 90° elbows add $200-$600 for labor and special fittings. Choice of material matters: aluminum flexible liners are cheapest, stainless double-wall or insulated liners cost more.
Site Conditions That Raise A Quote: Access, Masonry, And Roof Work
Poor access or needed masonry repairs can double labor time and add $500-$3,000. Tight attic access, roof scaffolding, corbels, or tuckpointing increase hours and require additional trades. If a chase needs opening or flashing must be replaced, add $250-$1,200 depending on roofing access and materials.
Practical Ways To Lower Your Chimney Liner Price
Controlling scope and preparing the site cuts costs: clear attic space, provide ladder access, and schedule midweek to avoid rush premiums. Other strategies: choose a smaller-diameter liner if code allows, accept a flexible stainless liner instead of heavier rigid systems, and get at least three itemized quotes to compare labor-hour assumptions.
Regional Price Differences And What To Expect In Your Market
| Region | Typical Multiplier vs. National Avg | Example Average Price |
|---|---|---|
| Northeast (urban) | +15%-30% | $1,000-$2,400 |
| Midwest | -5%-10% | $700-$1,600 |
| South | -5%-10% | $650-$1,500 |
| West (coastal) | +10%-25% | $900-$2,300 |
Labor rates and permit costs drive regional differences; metropolitan areas typically pay 10%-25% more than rural markets.
Installation Time, Crew Size, And Typical Job Duration
Most single-furnace liner installs take 4-10 hours with a 2-person crew; complex relines take 1-3 days with 2-4 technicians. Simple installs: 4-6 hours, two techs; tall or masonry-involved jobs: 8-24+ hours, extra helpers for scaffold and roof work.
Common Add-Ons, Inspections, And Permit Fees To Budget For
Budget an extra $150-$800 for inspection, flashing replacement, chase caps, and old-liner disposal. Typical items: chimney cap $75-$300, flashing replacement $150-$600, inspection/CO $50-$300. Permit needs vary by municipality; ask contractors to include permit line items on quotes.
