How to Recycle an Old AC Unit or Chiller (And Get Paid for It)

You can’t just haul an old AC unit or chiller to the curb or drop it straight on the scrap pile — the refrigerant inside has to come out first, legally and on record, before that unit is scrap metal at all. C4S Recycling handles both steps for HVAC and mechanical contractors, property managers, and homeowners across El Cajon and East County: EPA-compliant refrigerant recovery, then a fair cash payout on the copper, aluminum, and steel once the unit is clear to process.

Why You Can’t Just Scrap an AC Unit or Chiller As-Is

Central air conditioners, chillers, and most retail refrigeration units still contain refrigerant when they come off a job site, and federal law treats that refrigerant as hazardous to the ozone layer if it’s vented into the air. Under Section 608 of the Clean Air Act, the EPA’s disposal requirements state plainly that this equipment “must have refrigerant recovered…before disposal.” That recovery step is what separates a legally scrapped unit from one that’s just been abandoned with the refrigerant intact.

EPA Refrigerant Recovery: What the Law Actually Requires

Recovery has to happen before the unit is disposed of or broken down for scrap, and it has to be documented. For equipment entering the waste stream with refrigerant still in it, the EPA requires the final disposer to obtain a signed statement that includes “the name and address of the person who recovered the refrigerant, and the date.” Technicians performing that recovery generally need Section 608 technician certification, which requires passing an EPA-approved test tied to the type of equipment they’re servicing. Skipping this step doesn’t just risk a fine — it leaves a paper trail gap that shows up if a contractor’s job ever gets audited.

What Happens After Refrigerant Recovery

Once refrigerant is recovered and documented, the unit becomes exactly what it looks like: a mix of ferrous and non-ferrous scrap. Copper coils and wiring, aluminum fins and housing, and a steel or aluminum shell all get sorted and priced separately — copper and aluminum pay considerably more per pound than the steel casing. If you want the full breakdown of how that pricing works and what changes your payout, our scrap metal prices guide covers it, and our ferrous vs. non-ferrous guide explains why the metals inside one unit don’t all price the same.

Residential AC Units vs. Commercial Chillers: What’s Different

A residential split-system AC unit is usually a single trip — refrigerant recovery, then straight to the scale. A commercial chiller is a bigger job: more refrigerant volume, often a different refrigerant type, and sometimes multiple compressors that each need separate recovery and documentation. Chillers also carry more recoverable copper and steel by weight, which is part of why property managers and mechanical contractors handling a chiller swap-out should expect a materially different payout than a homeowner scrapping a single window unit.

Age matters too. Older units built before the mid-2000s tend to use heavier-gauge copper tubing than newer, more efficient models, which can mean a slightly better payout pound for pound even though the unit itself is less valuable as working equipment. A unit that’s been sitting outside for years with a rusted-through cabinet still has recoverable copper and aluminum inside — it’s rarely worth nothing, even when it looks like scrap already.

How Much Your Old AC Unit or Chiller Is Worth

Value comes down to size, metal content, and condition. A standard residential condenser with intact copper coils is worth more than one that’s already been stripped or corroded. Commercial chillers, with their higher copper and steel content, typically pay out more in total dollars even though the per-pound rate on any single metal hasn’t changed. Because copper and aluminum prices move with the broader metals market, we quote actual numbers by phone rather than posting a flat rate — get today’s pricing before you schedule a pickup or drop-off. As a rough guide, expect a standard residential condenser to pay less than a commercial package unit, and a package unit to pay less than a chiller — the gap is almost entirely the copper and steel weight difference between them, not anything special about the equipment type itself.

Contractors: Bulk AC/Chiller Recycling and Job-Site Documentation

HVAC and mechanical contractors pulling multiple units off a single job need more than a one-time drop-off — they need a documented, repeatable process. We set up commercial accounts with scheduled pickup, roll-off containers for larger tear-outs, and the refrigerant-recovery paperwork trail that keeps a contractor covered if the job ever gets reviewed. This is the same EPA-compliant process our sister company, C4S Demolition, has run on demolition and mechanical job sites in East County for over 20 years — see our About Us page for that history. We run regular pickups across El Cajon, Santee, La Mesa, Lakeside, Spring Valley, Rancho San Diego, and Alpine — check our service area coverage to confirm your job site is on the route.

Frequently Asked Questions

Can I scrap an AC unit myself without recovering the refrigerant?

No. Federal law under Section 608 of the Clean Air Act requires refrigerant to be recovered before an AC unit or chiller is disposed of or scrapped, and the recovery has to be documented with the name of the person who performed it and the date.

How much does it cost to have refrigerant recovered?

We handle recovery and recycling as part of the same visit, so there’s no separate line-item cost to you — the payout for the unit’s copper, aluminum, and steel is calculated after recovery is complete.

Do you pick up chillers from commercial properties?

Yes. We handle commercial chiller removal for property managers and mechanical contractors, including scheduled pickup and documentation for multi-unit tear-outs.
