Contractor wants to install additional air return on floor 8x14

I'm getting a new system installed in a couple of weeks.

Trane 2 Stage 80% Gas Furnance S8V2 with variable speed blower and Trane XV18 Heat Pump which has variable speed. I currently have just one return on an internal wall in the hallway. My contractor wants to install a floor return 8"x14" so I'm trying to figure out where would be best to install that in my ranch home. I do also have a full basement and crawl space as well from an addition that was put on the home years ago.

I assume he wants to add a second return for the addition ? Which I would say he is thinking .

Yes or I think he mentioned maybe for more airflow for the heat pump to work more efficently.

Thanks for your comments.

You have a good contractor. He knows what he's doing. High-efficiency systems move more air than conventional systems. It's also common for home additions to include air supply but no additional return capacity, so your system may be short on return air to begin with.

Thank you for that explanation!

Yes. I agree with the above posts. If he wants to install it it means you need it.

I will take that advice and have them install one.

As far as deciding where, let the contractor figure it out. He is the one that is going to connect the other side to the new furnace. If you choose a location that makes it difficult to get the duct from the hole in the floor to the furnace, then you are going to make his job harder. (and that may cost more)

I always tried to pick the most aesthetically pleasing place in my customers homes.

Thanks again Ed!
