When a part fails on the job, the last thing you need is a confusing warranty process. This guide breaks down exactly how Carrier parts claims work, depending on how the part was ordered—either through a Carrier National Credit Account (CRNA) or a supply house.
If the original equipment order was placed through a Carrier National Credit Account (CRNA), follow the buyback process and submit the claim using the Carrier form.
If the original equipment order was placed through a supply house account, reach out to your local Carrier-partnered supplier to start the passthrough claim process.
No matter the path, always keep the unit serial number, order confirmation, and repair invoice—you’ll need them to file.
Option 1: CRNA Buyback Warranty Claim
Use this if the part was ordered through a Carrier National Credit Account (CRNA)
Step-by-step:

Use the serial number to look up the correct part via:
A supply house
HVAC Partners Portal (if you have access)
The HVAC Partners lookup tool (if you have access)
Place the order through Sibi or HVAC Partners
The order must go through the CRNA buyback flow
Do not order the part at the branch
Pick up the part and complete the repair
File the warranty claim
Fill out the Carrier Warranty Form
Email it to: CRNAwarranty@carrier.com
Option 2: Supply House Passthrough Claim
Use this if the part was ordered using your own supply house account
Step-by-step:
Get the unit’s serial number
Bring it to the supply house counter or contact their tech support team.Request the replacement part
The supply house opens a warranty ticket for the part
You’ll need to pay out of pocket when you pick it up
File the warranty claim
After the repair, the supply house will help submit the claim for reimbursement
Timing and paperwork can vary by distributor
Not sure which path to take?
