The first place to check is your purchase invoice, manufacturer certification statement, or contact the installer.

You can also check the IRS list of registered manufacturers.

This site helped me:

QMID Lookup 2026 | Complete IRS QMID Code List for Form 5695 | Rebate.Blue

My furnace brand is just one of many brands made by the manufacturer Carrier, and by searching my brand name (Bryant), it found Carrier and showed a list of all the Carrier brands which included Bryant. (This was helpful and very reassuring, as I failed to find Bryant in other lists, not realizing it was not the manufacturer.) The QMID refers to the manufacturer, so it is the thing you want, but I was impressed that the search at the link found it by brand name.
