Ask Foreman

Can you verify this before I keep going? I’m looking at: Installing supply and return ducts that are reversed at the air handler. What’s the approved correction for this job?

Do not

Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
