Why Copper Is Valuable In Window AC Units

Copper is a core component in window air conditioners because of its outstanding ability to conduct heat and electricity. It’s used in the coils, wiring, and compressor windings, making it valuable not just functionally but also in terms of scrap value. With copper prices remaining high (typically $3–$5 per pound in the U.S. as of 2025), salvaging it from discarded units has grown in popularity.

Typical Copper Content: What To Expect In A Window AC Unit

The amount of copper inside a single window AC unit depends on factors like brand, model, age, and size. On average, you can expect to recover between 2.5 and 5.0 pounds of copper from a common residential window AC. Larger or older units may contain more copper than newer, smaller, or more energy-efficient models that use aluminum for cost savings.

Breakdown By Component

• Compressor: Contains the most copper, usually in the form of internal windings. This component alone yields about 1 to 2 pounds of copper, but requires effort to extract.
• Evaporator and Condenser Coils: The next biggest source, consisting of copper tubing and fins. These typically add up to another 1.5 to 2.5 pounds, especially in older units before manufacturers switched to aluminum or mixed metals.
• Wire Harnesses and Connections: Insulated wiring and connectors usually add only 0.2 to 0.5 pounds but are easier to remove and process for recycling.

Replacing Copper With Aluminum: Recent Trends

The rising price of copper has forced manufacturers to substitute aluminum for copper in many newer window AC units. This means that current models in stores may have noticeably less copper than units built before 2010. Scrap values, therefore, can vary widely. Always check for copper tubing and coil color—copper is reddish, while aluminum is silvery-gray.

Step-By-Step Guide: Extracting Copper From A Window AC Unit

1. Safety Precautions

• Vent Refrigerant Legally: Federal law (EPA regulations) prohibits venting refrigerant into the atmosphere. Only certified professionals should reclaim or dispose of refrigerants like R-22 or R-410A.
• Unplug Unit Before Disassembly: Always disconnect the power before working on any AC appliance.
• Wear Gloves And Goggles: Metal edges are sharp, and scraping can create flying debris.

2. Tools And Preparation

• Wrenches and screwdrivers (variety of sizes)
• Wire cutters and pliers
• Reciprocating saw or hacksaw (for cutting coils and compressor casing)

3. Disassembly Process

1. Remove Cover Panels: Use a screwdriver to unscrew and remove the outer plating.
2. Detach Wiring And Electronic Controls: Cut or unplug any visible wires. Set aside for copper recovery.
3. Extract Evaporator And Condenser Coils: These are usually at the front and back of the unit. Handle with care; the copper tubes run throughout.
4. Open The Compressor: The compressor is a sealed steel cylinder—open it with a steel saw. Inside, windings of copper wire can be pried out. This is the most labor-intensive step, but also the most rewarding for copper recovery.
5. Sort And Clean Copper: Separate pure copper (bare bright, #1 and #2 grades) from insulated or mixed metal pieces for higher scrap prices.

How To Identify Real Copper In AC Components

• Visual Indicators: Copper pipes and coils have a distinctive reddish-brown luster. If you scrape a silvery coating away and find reddish metal underneath, it’s copper.
• Magnet Test: Copper is non-magnetic. If a magnet sticks, the metal is either steel or contains iron.
• Weight And Flexibility: Copper is heavier and more malleable than aluminum, making it more valuable per pound.
• Insulation Color: Electric wires are often covered in colored plastic but the metallic core is copper.

Resale And Recycling Value Of Copper From AC Units

The value of recovered copper depends on cleanliness and local scrap yard prices. As of mid-2025, U.S. copper scrap prices range from $2.80 to $4.30 per pound for the most common grades. Prices for insulated wire will be less, as the weight of plastic insulation is subtracted at the yard. Typically, copper windings and tubing from an AC unit, if cleaned, will fetch a better price (bare bright copper wire is most valuable).

Copper Type	Typical Scrap Value (per lb)	AC Component Example
Bare Bright Copper	$3.80 – $4.30	Coil tubing, clean windings
#1 Copper	$3.60 – $4.00	Thicker wires, uninsulated pieces
#2 Copper	$3.00 – $3.60	Mixed/mildly tarnished copper, thinner wires
Insulated Copper Wire	$1.20 – $2.40	Harnesses, electrical connections

Factors Affecting Copper Content In AC Units

• Unit Size And BTU Rating: Larger air conditioners (measured in BTUs) have more coils and copper windings.
• Age Of Appliance: Older units (pre-2010) generally have more copper. Modern models may use aluminum for cost savings and efficiency.
• Manufacturer And Design: Premium brands often include more copper for performance, while cheaper or eco-models might use aluminum instead.
• Repair History: Sometimes, previous repairs may have replaced copper parts with aluminum alternatives, impacting yield.

Environmental And Economic Benefits Of Recycling Copper From Window ACs

Recycling copper is both profitable and environmentally friendly. Reusing metals saves over 85% of the energy required for new copper mining. It reduces landfill waste and eliminates the need for dangerous mining activities. For scrap sellers, removing the copper from broken AC units is an easy way to support sustainability while earning extra cash.

Sustainability Facts

• Each ton of recycled copper saves 4 tons of CO2 emissions.
• Recycled copper maintains its quality for future use without degrading.
• Recycling AC units removes harmful refrigerants and metals from the waste stream, protecting soil and water.

Legal And Environmental Considerations

• Refrigerant Handling: U.S. law requires refrigerant be recaptured by licensed technicians before an AC unit is scrapped or dismantled.
• Waste Disposal: Most states have e-waste programs for responsibly recycling old appliances. Dumping electronics is illegal in many jurisdictions.

Tips For Maximizing Copper Yield And Scrap Value

• Remove All Insulation: Clean, bare copper fetches the top price. Strip wires using a wire stripper if possible.
• Avoid Mixing Metals: Scrap yards pay less for mixed-metal batches. Sort copper, aluminum, and steel separately.
• Bundle In Bulk: Bring multiple disassembled units at once—the more copper, the higher bargaining power at scrapyards.
• Time The Market: Prices fluctuate based on global supply and demand; check spot prices before selling.

FAQs: Copper In Window AC Units

Is It Legal To Scrap A Window AC For Copper At Home?

Removing copper from appliances is legal in most areas, provided all refrigerant is properly handled. Some cities require dropping off appliances at approved collection points, especially if refrigerant remains in the unit.

How Hard Is It To Open The Compressor?

Opening the compressor is labor-intensive since it’s a sealed steel container. A reciprocating saw or angle grinder is necessary. For some, the effort and risk may outweigh the extra copper—sometimes it’s better to sell compressors as-is for a set price.

What If My Unit Has Mostly Aluminum Coils?

Newer and budget models substitute copper with aluminum. Aluminum has value—about 30–40 cents per pound as scrap—but copper remains easier to sell and is higher-priced. Always separate metals to maximize value.

Best Practices For Responsible AC Unit Recycling

• Use Certified E-Waste Programs: Many states and cities run recycling events or have approved facilities for safe AC recycling.
• De-Pollute First: Always recover refrigerant through licensed professionals or salvage yards with proper recovery equipment.
• Prioritize Personal Safety: Sharp metals, electrical components, and pressurized parts (like compressors) can be hazardous without proper gear and tools.
