🛠️The HVAC Teardown & Grading Checklist
⚠️ STEP 0: THE LEGAL & SAFETY WARNING (Read This First)
DO NOT CUT LINES ON A CHARGED UNIT.
Refrigerant (Freon) is hazardous and protected by EPA regulations. Venting it into the atmosphere is illegal and dangerous.
-
The Rule: Only accept units that have been evacuated (drained) by the HVAC technician before you pick them up. Look for the cut lines or ask for certification.
-
The Check: If the copper lines are crimped shut or the valves are closed tight, assume it's pressurized.
1. The Crown Jewel: Aluminum/Copper Radiators (ACR)
The radiator fins are the most valuable part of the unit. You have two ways to sell this, and the difference in price is massive.
Option A: Dirty ACR (The "Quick Flip")
-
What it is: The copper tubes running through aluminum fins, but with the galvanized steel end-plates still attached.
-
Effort: Low.
-
Price: Decent, but you're leaving money on the table.
Option B: Clean ACR (The "Scrap Master Standard")
-
What it is: You take your Sawzall or angle grinder and cut the steel end-plates off flush with the aluminum.
-
Effort: Medium (5 minutes of cutting).
-
Price: High. This is premium feedstock.
-
Profit Tip: Don't cut into the copper loops when removing the steel ends. Save those copper loops (knuckles) for your #2 Copper bucket.
2. The Heart: Sealed Units (Compressors)
This is the heavy black "pot" at the bottom of the unit.
-
Composition: A thick steel shell with a copper-wound electric motor inside and lots of oil.
-
Grading: Sell this as a "Sealed Unit" or "AC Compressor."
-
Do NOT: Do not try to cut these open to get the copper unless you are extremely experienced. The thick steel casing burns through saw blades, and the oil makes a huge mess. It is rarely worth the labor time.
-
The Strategy: Leave them whole. They are heavy (40–80 lbs), and weight adds up fast.
3. The Muscle: Electric Motors
The fan motor sits on top or inside the unit.
-
Removal: Unbolt it from the fan blade and the grate.
-
Grading: Sell as "Electric Motor."
-
The Upgrade: If you see a large transformer or a particularly old motor, check the windings. If they are copper (scratch them to check—gold color is copper, silver is aluminum), it's a standard motor. If it's aluminum wound, it's worth less (Meatball motor), but most yard scales just buy them all as "Electric Motors."
4. The Veins: Insulated Copper Wire
Don't ignore the wiring harness.
-
Low Voltage Wire: The thin thermostat wire. Usually graded as low-grade or "communications wire."
-
Power Wire: The thicker cables connecting the compressor and fan.
-
Grading: Clip the plugs off. This is usually #2 Insulated Copper.
-
Profit Tip: If the wire is thick (like the size of a pencil or thicker), strip it! That turns #2 Insulated into Bare Bright Copper—the highest value item in the yard.
5. The Skeleton: Shred Steel (Light Iron)
Once you have pulled the Radiator, Motor, Compressor, and Wire, you are left with a hollow steel box.
-
Grading: Shred / Light Iron.
-
Action: Crush it down if you need space in the truck, or fill it with other light iron scrap to maximize density.
-
Note: Keep the screws! They are steel. Throw them in your steel bucket.
📊 Quick Reference: The HVAC Value Hierarchy
| Component | Yard Grade (Ask for this name) | Relative Value |
| Stripped Wire | Bare Bright Copper | 💰💰💰💰💰 (Max) |
| Clean Fin | Clean Aluminum/Copper Radiator | 💰💰💰💰 |
| Dirty Fin | Dirty Alum/Copper Radiator | 💰💰💰 |
| Black Pot | Sealed Unit / Compressor | 💰💰 |
| Fan | Electric Motor | 💰💰 |
| The Box | Shred / Light Iron | 💰 (Volume Game) |
Now you know how to break it down. Don't let the yard classify your hard work as "shred." Sort it, bin it, and demand the right price.
