Nice job and a common problem, my dealer did that under warranty and said they would be checking all of them coming in from then on. Since, like us, you have a 2017 you should also check your return air ducts. On ours the ducts were cardboard and collapsed. I put two 9" lengths of 11/2" PVC pipe lnto each side of each one and opened that up. I also cut half the fins off of 5 of the supply ducts and shortened the shaft to match the ducts on all of them to increase the air flow.
