Tax Credit / Rebate Paperwork

MRCOOL QMID Codes

Some lender, tax, or rebate forms ask for a QMID (Qualified Manufacturer ID). MRCOOL can appear under two qualified manufacturer entries. Use the code that matches the manufacturer name shown on your form.

Option 1: MRCOOL

QMID

Use this when your form lists MRCOOL as the manufacturer.

D0G0

Pronunciation: Dee-zero-gee-zero

Option 2: HVAC Distributing LLC

QMID

Use this when your form lists HVAC Distributing LLC.

O5Y7

Pronunciation: Oh-five-why-seven

How to Choose the Right QMID

  • If the paperwork shows the manufacturer as MRCOOL, use D0G0.
  • If the paperwork shows the manufacturer as HVAC Distributing LLC, use O5Y7.
  • If you do not see MRCOOL listed, search the manufacturer list for HVAC Distributing LLC.

Tip: Many forms use a dropdown list. The code is tied to the entry you select, so match the name first, then confirm the QMID.

What You Should Keep for Your Records

If you’re finalizing paperwork, these items are commonly requested:

  • Your invoice/receipt (equipment + installation details)
  • Outdoor unit model and serial number
  • Indoor unit model and serial number(s)
  • AHRI certificate number (if requested by your lender/utility/rebate program)
