Wanting a laboratory with no relationship to a reclaimer is a reasonable thing to want. If your situation calls for it — a disputed batch, a contract that requires it, a counterparty who will not accept a result from a lab that shares owners with the buyer — then use one, and do it without feeling you owe us an explanation.
AHRI’s directory lists the certified refrigerant testing laboratories. It is public, we do not control it, and it is the right place to look. We publish no claim about any other laboratory; look them up yourself.
We would rather you go in with your eyes open than send us a sample you are going to doubt.
And if you want us anyway
Take the split. Tell us at registration that you want the sample drawn for two, send the second portion wherever you like, and compare. It costs you the second test; what it costs us is the chance to be wrong in public.
If anything on this page is not what you were told, or not what happened on your sample, call and say so.
