Scrap Metal Revenue and the Records It Requires
Why this matters
A change-out shop throws off a steady stream of copper, aluminum, brass and steel: condenser coils, compressors, line sets, water heaters, wire, old motors. It is real money, it is the easiest money in the business to lose track of, and it moves across a counter that, by state law almost everywhere, is writing down exactly who brought it in. If the shop has no scrap policy, the yard's log is the only record that exists, and it lists individuals and dates, not jobs or customers.
What the yard is recording, and why
Metal theft laws spread through nearly every state from the late 2000s onward, when copper prices drove a wave of stripped vacant houses, cut utility wire and, more recently, stolen catalytic converters. There is no general federal scrap-dealer identification law; bills have been introduced and not enacted, so this is a state-layer subject throughout.
What a state statute commonly requires of the yard (the "recycler" or "secondhand metal dealer" in most statutes):
- Seller identity. A government photo ID, recorded or scanned, for every transaction.
- Vehicle. The plate number, sometimes a description.
- Material. Description and weight by grade, often with a photograph of the load.
- The seller's own record. A signature, frequently a photograph of the seller, and in some states a thumbprint.
- Payment controls. Restrictions on cash for certain metals, a delay before payment, or payment only by check or electronic transfer.
- Restricted items. Lists the yard cannot buy without proof of ownership or a trade credential: utility and telecom wire, burnt insulated wire, manhole covers, beer kegs, catalytic converters, and in some states air-conditioner coils and condensers.
- Retention and reporting. Records kept for a set period and open to law enforcement on request, and in some states uploaded daily to a statewide database that police search by name.
The spread is wide. California sits at the strict end: for nonferrous metal, its Business and Professions Code requires the seller's thumbprint and photograph and holds payment for a few business days rather than paying cash at the window. Other states require little beyond an ID and a log entry. Read your own state's scrap-metal statute and ask the yard what it collects; the yard knows its own rules better than any summary.
The federal piece that does reach the counter is refrigerant. Under EPA's section 608 rules (40 CFR Part 82, Subpart F), the last person in the disposal chain for a small appliance (a refrigerator, window unit or dehumidifier) must either recover the refrigerant or verify it was already recovered, and yards commonly do that with a signed statement giving the name and address of whoever recovered it and the date. Larger equipment such as a split-system condenser must have its refrigerant recovered by a certified technician before it is disposed of, and many yards ask for the same statement on it. That signature is a federal compliance record in the name of whoever signs it (see related: Refrigerant Recovery Procedures).
Whose scrap it is
Removed equipment belongs to the property owner unless the contract says otherwise, so the scrap is only the shop's to sell where the estimate or service agreement transferred it. That question has its own card (see related: Who Owns the Old Equipment You Remove). This card assumes the transfer clause is in place and deals with what the shop does with material it owns.
Why the record matters more than the money
On a single job the scrap is small against the ticket. Across a year of change-outs it is a noticeable line, and the record attached to it does three jobs the money does not:
- It answers the police. When coils are stolen off a rooftop across town, the detective searches the yard database by name. A tech whose name appears 20 times needs the shop to be able to say, ticket by ticket, which job each load came from.
- It answers the customer. A customer who later asks what happened to their old unit gets a ticket number and a date, not a shrug.
- It answers the refrigerant question. Every sealed unit sold with a signed recovery statement should match a recovery log entry on a job. If it does not, the shop has a signature without a recovery behind it.
The shop policy, in six lines
- Scrap from jobs is shop property where the contract makes it so, and is sold only through the shop's account at the yard. Most yards will open a business account that names the people authorized to sell on it; their ID is still recorded, but the transaction is the company's.
- Every ticket carries job numbers. Write them on the ticket, or ask the yard to enter them in the reference field. A ticket without job numbers is a ticket the shop cannot defend.
- Proceeds go into the business account, by check or transfer to the company. Never cash to the person at the window.
- Scrap is sorted and stored at the shop by grade, in labeled bins or bays, not left in vans. A coil in a van for two weeks is a coil nobody can trace.
- Sealed units leave only with a recovery log entry behind them. The person signing the yard's refrigerant statement checks the log first.
- If the crew shares in scrap, that is a written decision, run through payroll. Letting techs keep scrap informally is compensation that nobody reported. How to structure a crew share is a question for the shop's accountant, not the yard.
Sorting is where the value is made or lost
Yards pay by grade, and the gap between a clean grade and a mixed one is large. A condenser coil with its steel end plates and brass fittings still on goes in a mixed copper-aluminum grade; the same coil cut clean sells higher. An insulated wire bundle is worth less than the stripped copper inside it. A compressor goes in sealed units regardless.
The trade-off is labor, so put it in hours. If cutting a coil clean takes a tech 20 minutes at the shop, the question is whether the grade uplift on that coil beats 20 minutes of loaded labor cost. On most residential coils it is close, and on a slow afternoon it can pay; during a heat wave, with calls stacked, it never does. Make it a rule rather than a mood: cut clean only when a tech is waiting on parts or between calls, and never strip wire with a knife at all (the hand injuries are routine and the uplift is not worth it).
Sorting also has a hazard side. Cutting a coil means sharp fin edges and sometimes a residual oil film from the compressor circuit; wear cut-resistant gloves and eye protection, and confirm the refrigerant was recovered before a saw or snips touches a tube, because a coil that still holds a charge vents it into your face.
Worked example: one month through the counter
A six-tech HVAC shop runs nine system change-outs in March. Its estimates transfer removed equipment to the shop, except where the customer elects to keep it.
Disposition first. Of the nine jobs, one customer kept their old condenser for a relative's cabin, and one failed compressor under warranty went back to the distributor for credit, leaving that unit's coil and cabinet as scrap. So eight jobs produced scrap: seven complete systems and one system minus its compressor.
Two trips to the yard. The shop sells on its business account, and the warehouse lead makes both runs. The first ticket, mid-month, looks like this:

Reconciliation at month-end. The office lays the two tickets beside the job list. The first ticket covers four jobs and four sealed units. The second covers the other four jobs and only three sealed units, because the warranty job's compressor went to the distributor. Seven sealed units sold, and the recovery log shows a recovery entry on each of the seven jobs, so every unit traces. The gap is the signature: the warehouse lead signed the yard's statement for all seven, and he recovered none of them. The policy now has him read each log entry, with the recovering tech's name and certification number, before he signs, and the yard statement names that tech as the person who recovered it.
What the reconciliation produced. Nine jobs with a disposition each: eight scrap with a ticket number, one customer-kept with a note. Two tickets, eight job numbers referenced, seven sealed units, seven log entries, one process fix. The month's scrap check came to roughly the loaded cost of a day of one tech's time, which is the right size to understand it: not a revenue strategy, and not nothing.
What changes the answer. In California, the payment delay on nonferrous metal means the shop waits for the check, and the yard will want the seller's thumbprint, so the authorized sellers on the account should be the people who are actually comfortable giving it. In a state that lists air-conditioner coils as a restricted item, the yard may refuse the coils without a contractor license number or proof of ownership, which the business account and the job references usually satisfy, but confirm it before the first run rather than at the window with a loaded trailer.
The signal that the policy is not being followed
Scrap income that stays flat, or vanishes, while change-out volume rises. Nobody reports scrap leaking out of a shop; it shows up as a line in the books that stopped tracking the work. Compare the two once a quarter (see related: The Scrap Money Nobody Accounted For).
