Cool when AC or heat is on, smells like burning oil?

when i turn on my AC or heat, the air that it supplies smells very unpleasant. Recently, i had a damaged head valve gasket with leaking engine oil, and i had it replaced, plus the outside of my engine was cleaned and looks dry. What are some probable causes? thx

Does your car have an A/C cabin filter?

There still might be some residue from oil on the exhaust manifold or you have another oil leak getting onto the exhaust as well. Get some brake cleaner and spray down the manifold and pipes to get rid of the oil.
