Why Copper Is Important In AC Units
Copper is prized in air conditioning systems for its exceptional thermal and electrical conductivity. Its high durability and resistance to corrosion make it the metal of choice for key components like tubes, coils, and wire windings. These attributes are essential for efficient heat exchange, reliable motor function, and long-term operation of an HVAC unit.
Major Copper-Bearing AC Components
To accurately estimate how much copper a 5 ton AC unit contains, it’s helpful to understand which parts typically use the most copper. The primary copper components in a standard split or rooftop system include:
- Compressor windings: Usually consist of a copper wire coil encased within the compressor shell.
- Condenser coil: Comprised of copper tubing and sometimes copper fin stock, located in the outside condensing unit.
- Evaporator coil: Found inside the indoor air handler or furnace, also made of copper tubes and fins.
- Refrigerant lines: Copper piping connecting indoor and outdoor units—usually two lines per system.
- Electrical wiring and terminals: Includes insulated copper wire in the electrical control box and component connectors.
Copper Estimates: 5 Ton AC Unit By System Type
The total amount of copper in a 5 ton air conditioner varies depending on the brand, age, and technology. Below are typical copper content ranges:
| System Style | Approximate Copper Content (lbs) | Notes |
|---|---|---|
| Conventional Split System | 29 – 45 | Most common in American homes; includes furnace/air handler and outdoor condenser |
| Packaged Rooftop Unit | 33 – 54 | Larger footprint and slightly higher copper due to integrated components |
| Older Models (pre-2005) | 40 – 59 | Older units often have more copper due to less aluminum use in coil construction |
| Modern High Efficiency Units | 28 – 42 | May replace some copper with aluminum for cost savings and lighter weight |
How Size And Technology Affect Copper Content
Tonnage
The term “ton” in HVAC describes an AC’s cooling capacity, rather than its weight. A 5 ton air conditioner is designed for larger homes or commercial spaces, delivering about 60,000 BTUs of cooling power. The size and efficiency requirements generally mean more or thicker copper in the components, whereas lower-tonnage units will have noticeably less copper.
Technology Trends
Recent trends involve replacing traditional copper coils with aluminum or alloy due to rising copper costs. However, for 5 ton units, especially those produced before 2010, copper remains predominant in coil and tubing construction. Newer inverter and variable-speed units may marginally reduce copper volume by employing refined design and alternative materials.
Location Of Copper Within A 5 Ton AC
- Outdoor Condenser Unit: Major copper mass comes from condenser coil tubing, compressor windings, and connection lines.
- Indoor Evaporator Coil: Substantial copper found in the evaporator tubing and distributor header pipes.
- Refrigerant Tubing: Runs between indoor and outdoor units, typically seamless copper pipe in 3/8″ and 7/8″ sizes.
- Electrical Box: Smaller quantities of copper in wiring and relay terminals.
Comparison Table: Copper Content Versus Other Metals In AC Units
| Material | Common Use In AC | Approximate Content (5 Ton AC, lbs) | Relative Scrap Value |
|---|---|---|---|
| Copper | Coils, tubing, wire | 28 – 59 | High |
| Aluminum | Coils, casing, fins | 15 – 35 | Medium |
| Steel | Frame, panels | 80 – 180 | Low |
| Brass | Fittings, valves | 1 – 3 | High |
How To Recover Copper From A 5 Ton AC Unit
- Ensure all refrigerant is professionally removed to comply with EPA regulations before disassembly (it’s illegal and dangerous to vent refrigerants like R-22 or R-410A on your own).
- Dismantle the casing with basic tools such as screwdrivers, wrenches, and tin snips.
- Locate and remove copper coils, compressor, and tubing. The compressor will require opening to access copper windings, which is labor-intensive but worthwhile.
- Sort copper according to grade. Separating bare bright copper, insulated wire, and mixed metals maximizes scrap value.
- Consult a local scrap yard for recycling and price estimates—scrap yards often pay a premium for clean, separated copper.
Scrap Value: How Much Is The Copper From A 5 Ton AC Worth?
Copper is among the most valuable metals found in home appliances. As of early 2025, scrap copper prices range from $2.80 to $4.10 per pound for different grades. The typical 5 ton air conditioner unit yields about 30 – 55 pounds of recoverable copper:
- Low estimate (30 lbs at $2.80/lb): $84
- High estimate (55 lbs at $4.10/lb): $225.50
The actual value will fluctuate based on current commodity prices, copper quality, and regional demand. Bare bright copper wire brings the highest prices, while insulated or mixed copper fetch less per pound.
Factors That Influence Copper Content In AC Units
- Age Of Unit: Older air conditioners tend to have more copper, as most modern models use aluminum coils to save on manufacturing costs.
- Brand & Model: Premium brands sometimes use more copper for durability and efficiency compared to budget models.
- Application: Units built for commercial or industrial settings may contain additional copper bracing and specialized tubing.
- Design & Efficiency Standards: Higher efficiency units might require more copper for larger or thicker coils.
How To Visually Identify Copper Components
- Copper Tubing: Reddish-brown metal, non-magnetic, mostly in thick tubes or small-diameter coils.
- Bare Bright Copper Wire: Clean, shiny reddish wire, usually inside the compressor or control box.
- Insulated Wire: Copper wire wrapped in colored plastic insulation, found in electrical sections.
- Mixed Scrap (Motors And Compressors): Combination of copper windings and iron, often in the compressor shell.
How Manufacturers Are Reducing Copper Use In Modern ACs
Due to the rising prices of copper, HVAC manufacturers have shifted toward aluminum for condenser and evaporator coils in the last decade. Aluminum is lighter, less expensive, and offers comparable heat transfer in many applications. Hybrid coils, microchannel technology, and thinner-walled copper tubing innovations also reduce the total amount of copper required per unit.

Still, copper remains essential for certain parts (like compressor windings and high-pressure refrigerant lines) where aluminum can’t perform as well due to lower strength or conductivity.
Environmental And Recycling Benefits
- Copper recycling reduces the need for new mining, conserves natural resources, and lowers greenhouse gas emissions.
- Recycling AC units helps properly dispose of refrigerants and keeps harmful substances out of landfills.
- Many scrap yards offer incentives for separated, uncontaminated copper from air conditioners—benefitting both the environment and recyclers financially.
Estimating Copper Content Without Full Disassembly
- Manufacturer Data Sheets: Some brands list material weights in their technical literature or maintenance manuals.
- Industry Averages: HVAC wholesalers and recyclers use established formulas based on tonnage and year.
- Online Forums & Recycling Groups: Reports from homeowners and scrappers offer peer-verified numbers by model and size.
Frequently Asked Questions About Copper In 5 Ton Air Conditioners
Is It Legal To Scrap An Old Air Conditioner?
Yes, but it is illegal to vent refrigerant to the atmosphere. EPA-certified professionals must recover refrigerant before you dismantle or scrap the unit.
How Much Time Does It Take To Recover Copper?
Professional dismantling can take 1-2 hours for a 5 ton AC unit. Compressors and motors add more time due to their construction.
Which Copper Is Most Valuable?
Bare bright wire (free from insulation and corrosion) is worth the most; insulated and mixed copper less so.
Will Removing Copper Damage Other Parts?
Yes. Once you remove major copper components, the AC cannot be repaired or reused. Be certain the unit is at end-of-life.
Key Takeaways And Best Practices
- 5 ton AC units typically contain between 28 and 59 pounds of copper, depending on era, design, and technology.
- The largest copper masses are found in compressor windings, condenser/evaporator coils, and refrigerant tubing.
- Always ensure refrigerant is safely recovered before dismantling to comply with environmental laws.
- Scrap value can exceed $200 per unit at current market rates, making ACs a prime target for recycling.
- Modern units may yield less copper due to increased use of aluminum and hybrid designs.
Understanding copper content in a 5 ton AC unit is valuable for recycling, environmental, and financial considerations. Proper identification and dismantling maximize returns while supporting eco-friendly practices.
