The HVAC Teardown & Grading Checklist

🛠️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.
