Scrap value for a furnace varies widely depending on type, components, metal content and local scrap prices. This article explains how scrap yards assess furnaces, typical price ranges for different furnace types, steps to prepare a furnace for sale, and tips to maximize value while complying with safety and environmental rules. Key takeaway: most furnaces sell for parts value—primarily steel, copper, and aluminum—with typical ranges from under $20 to several hundred dollars for units with valuable components.
| Furnace Type | Common Scrap Value Range | Primary Valuable Materials |
|---|---|---|
| Older Residential Gas Furnace | $20–$150 | Steel, Aluminum, Small Copper Tubing |
| Furnace With Blower Motor | $50–$250 | Copper, Steel, Electric Motor |
| High-Efficiency Condensing Unit | $100–$400+ | Copper Coils, Aluminum, Steel, Electronics |
| Commercial/Industrial Furnace | $200–$1,000+ | Thick Steel, Copper Bus Bars, Motors |
How Scrap Yards Determine Furnace Value
Scrap yards price furnaces based on the weight and type of metal recovered, current market prices for scrap metals, and the cost of labor to dismantle and sort parts. Ferrous metal (steel and iron) is typically priced per ton or per hundredweight at lower rates than nonferrous metals like copper and aluminum. Nonferrous materials command significantly higher prices per pound, so scrap yards focus on extracting these components when determining a furnace’s worth.
Additional factors include local supply and demand, seasonal fluctuations, and yard-specific policies such as minimum payment thresholds or fees for disposal of non-metal parts.
Common Furnace Types And Typical Scrap Value
1. Basic Residential Gas Furnaces
Most single-family home gas furnaces contain a steel cabinet, a small amount of aluminum and limited copper in components like burners, heat exchangers or piping. Typical scrap values range from $20 to $150 depending on weight and presence of small copper pieces.
2. Furnaces With Electric Blower Motors
Units with electric motors increase value because the motor contains copper windings and sometimes a metal rotor that is recyclable. If the motor is intact and can be unbolted, yards may pay more. Typical ranges are $50 to $250.
3. High-Efficiency Condensing Furnaces
High-efficiency units often contain more copper tubing and aluminum heat exchangers plus control boards. These can be worth $100 to $400 or more depending on how much copper and aluminum can be recovered and local metal prices.
4. Commercial And Industrial Furnaces
Large commercial furnaces and industrial heating units contain thicker steel, larger motors, transformers and possibly copper bus bars. These can bring $200 to $1,000+ when disassembled properly, especially if copper and large motors are extracted.
Which Parts Add The Most Value
- Copper Components: Motors, transformers, wiring, coils and piping are the most valuable parts per pound.
- Electric Motors: Motors with copper windings and heavy steel casings are worth more, particularly if separated into copper and iron.
- Aluminum Heat Exchangers and Fins: Aluminum is less than copper but still valuable when separated.
- Control Boards and Electronics: Contain small amounts of precious metals but often aren’t worth extensive labor unless a yard recovers them.
- Heavy Steel: Adds weight value but pays much less per pound than nonferrous metals.
How To Prepare A Furnace For Scrap Sale
Proper preparation increases the amount of valuable metal recovered and can boost the price. Safety and legal compliance are essential.
Steps To Prepare
- Turn Off Power And Gas: Ensure utilities are disconnected by a qualified technician to avoid hazards.
- Remove Hazardous Materials: Drain and properly dispose of refrigerants and oil if present; some units are connected to AC condensers or contain compressors.
- Disassemble Nonmetallic Parts: Remove filters, plastic panels, gaskets and insulation to reduce landfill disposal and avoid deductions.
- Extract Copper And Motors: Remove accessible copper tubing, wiring and motors if the owner is comfortable and knows how to do so safely.
- Sort Metals Where Possible: Separate copper, aluminum and steel into distinct piles to get better rates for nonferrous metals.
Note: Many scrap yards will accept whole units and will do disassembly themselves, but separated metals often yield higher payments.
Safety, Environmental And Legal Considerations
Furnaces can house hazardous materials such as asbestos in older units, refrigerants in combined HVAC systems, and oil or chemicals. Handling these materials without proper training can violate federal and state laws and risk health.
EPA regulations govern disposal of refrigerants and certain hazardous wastes. Some states require certification to remove or handle refrigerants and electrical components. Always confirm local requirements and, when in doubt, use licensed technicians for dismantling and certified recyclers for disposal.
How Local Scrap Prices Affect Furnace Value
Scrap prices fluctuate daily based on global commodity markets, regional demand and supply. Copper prices often drive the value of electrical components; when copper is high, motors and wiring significantly increase a furnace’s worth.
Yards often list prices for ferrous and nonferrous metals online or via phone. Call local scrap yards for current copper, aluminum and steel rates. Keep in mind yards may pay less for mixed loads or charge handling fees for contamination or labor-intensive dismantling.
Ways To Maximize Scrap Value
- Separate Metals: Sorted copper and aluminum fetch higher per-pound rates than mixed loads.
- Remove Motors And Wiring: Motor copper is valuable—disassembled motors often pay more than whole units.
- Shop Around: Compare offers from multiple yards and ask about weights, tare fees and payment methods.
- Sell In Bulk: If dismantling multiple units, bringing larger quantities can result in better per-pound prices.
- Keep Documentation: For larger sales, proof of ownership and identification may be required; maintain records to expedite transactions.
Typical Price Examples And Calculation
Example calculation using hypothetical local prices: copper at $3.50/lb, aluminum at $0.70/lb, steel at $0.05/lb. A small furnace with 5 lb copper, 10 lb aluminum and 60 lb steel yields: (5×3.50) + (10×0.70) + (60×0.05) = $17.50 + $7.00 + $3.00 = $27.50. Additional motor copper or heavier components increase totals.
Key Point: High-efficiency furnaces and units with larger motors or transformers can contain 10–50+ pounds of copper, dramatically increasing scrap value.
How To Sell A Furnace For Maximum Return
Options
- Direct To Scrap Yard: Fast and straightforward; yard may offer dismantling but will discount for labor.
- Sell Parts Separately: List motors, copper tubing, controls and blowers on local marketplaces for higher combined returns.
- Use A Commercial Recycler: For large commercial units, recyclers or industrial metal buyers may pay more for bulk or specialized metals.
- Contract Dismantling Services: For complex or hazardous units, hiring a licensed dismantler may be necessary and could net a better final price after professional recovery.
Before selling, determine the effort required to remove valuable components versus the incremental payment increase. For small residential units, the time and risk to extract tiny amounts of nonferrous metal may not be worth the gain.
Common Questions And Practical Tips
Are Furnace Heat Exchangers Worth Anything?
Heat exchangers are often made of aluminized steel or stainless steel. Stainless parts are more valuable. If the heat exchanger contains copper, value increases. Otherwise, heat exchangers add weight but limited nonferrous value.
Will Scrap Yards Pay For Old Boilers And Heaters?
Yes, most yards accept boilers and heaters. Large boilers may contain heavy steel and copper components and can be worth several hundred dollars or more, especially in commercial applications.
Is It Legal To Scrap A Furnace From A Rental Property?
Ownership proof may be required by some yards. Landlords should maintain records. Tenants should not remove or sell fixtures without permission. Always verify who owns the property before scrapping.
Does Age Reduce Scrap Value?
Age does not inherently reduce metal value, but older units may contain hazardous materials such as asbestos or be more labor-intensive to dismantle. These factors can reduce the net payout.
Resources And Where To Get Current Prices
To get accurate, up-to-date values, consult local scrap yards, metal pricing websites, and commodity market reports. Industry trade associations and local recycling centers can also provide regional pricing trends and regulatory guidance.
Action Steps: Call multiple yards for live quotes, ask for breakdowns by metal type, and confirm any fees or documentation requirements before transport.
