HVAC unit making “knocking metal” noise when heat is on and when it goes off?

what could be the cause of this?
We can hear it under the house even tho of course the HVAC unit is outside…..it’s like a knocking noise (just once) of metal against metal, with a slight echo……
What could be the cause of this?
We have a 1 yr warranty on the house, as we just bought it in August….is this worthy of a service call? what might they do to it?
I dont know who the contractor is, as it’s an updated 50yr old house, made modern. Is this something that the house warranty that the sellers bought, will cover?
