Air Return Size change

I'm a new homeowner and this is my first post.
I'm in the process of replacing the existing air conditioning unit for a new one. Planning to go with a Rheem 4 Ton 16 SEER. The contractor told me that new indoor unit is taller than the one existing now so the new free space below air filter could be approximately 18". Actually this free space is 34".

I like to know if there will be any issues with the airflow return after new unit is installed. I have attached pictures for better illustration.
Thank you!

It will not be a problem. The airflow will still be fine.
