modify ductwork to accommodate a 4 or 5 inch filter

Is $1,500 to modify ductwork to accommodate a 4 or 5 inch filter a fair price?

Project Details

I am looking to replace my current 1 inch filter setup with a 4 or 5 inch filter. I received this quote, but I am unsure if the proposed duct modification is the only solution. My hunch is that it might be possible to squeeze a 4 inch filter into the existing elbow, and I am wondering if doing that would cause airflow problems.

Quote Details

This quote covers the modification of existing ductwork to accommodate a larger 4 or 5 inch filter, replacing the current 1 inch filter setup. - Ductwork Modification: Reduce the 14 inch size duct to 10 inch at approximately chest height. - Elbow Creation: Create a bigger elbow where the duct goes into the unit.

Thank you for your feedback!
