Sell surplus HVAC control boards

Selling HVAC control boards

What we buy and how it works

We buy HVAC control boards: integrated furnace controls, ignition and defrost boards, ECM motor modules, rooftop and air handler controls, chiller and VRF boards, and the expansion and communication cards that plug into them. New in the box, pulled from working equipment during a changeout, or taken off a unit that was scrapped for another reason. One board or a contractor's whole back room. Email the number printed on each board and a photo of it, and you will have an offer within two hours. The valuation is free and there is no obligation. If you accept, we send a prepaid label, and for a pallet we book the pickup, and you are paid the day the shipment arrives.

What we pay for

Boards of every kind, with or without their original box, mounting standoffs and wiring harness. A board that has been fired is bought as long as it worked when it came out. If the condenser fan motor, inducer or blower, or building controller came off the same unit, send those numbers in the same email.

Brands we buy

Carrier, Bryant and Payne HK, HN and CEPL boards. Trane and American Standard CNT, MOD and BRD. York, Coleman, Luxaire and Source 1. Lennox, Armstrong Air and Ducane. Rheem and Ruud 47- and 62- numbers. Goodman, Amana and Janitrol PCB boards. Daikin and McQuay. Nordyne and Intertherm. Honeywell ST9 and S89 and White-Rodgers 50A and 50V controls are bought whatever equipment they came out of. Every brand we take is listed below. If yours is not there, send the number anyway and we will tell you either way.

Send the number on the board, not just the equipment label

HVAC boards usually carry two numbers: the manufacturer's part number on the equipment label or the box, and a different number printed on the board itself by whoever made it. A Lennox 103217-03 may also carry a short code such as 65W69, and a Carrier HK42FZ064 board can show a CEPL number as well. Buyers search both, so send every number you can read, exactly as printed. A photo of the whole board face, close enough to read the silkscreen, is the fastest way to list it.

New and used

New boards in the box, often bought as truck stock and never fitted, are the easiest to price. We also buy boards pulled from working units when the equipment was replaced for its age rather than a fault. Say which it is. For a used board, tell us whether it was working when it came out, whether the relays and the transformer are intact, and whether the harness is with it.

Where HVAC boards come from

HVAC contractors replace whole furnaces and rooftop units long before every board in them has failed, and the good boards come back to the shop. Distributors clear truck stock when a model is superseded, and property managers scrap equipment on a schedule. Those shelves of pulled boards and unopened boxes are what we are asking you to send.
