Very low air flow
I am running my HVAC only in the fan mode to trouble shoot. Very weak air flow coming out of the vents that are even closest to the unit and much worse further out.
Have checked all the filters and returns and they all seem clean. Blower motor seems to be running fine (no funny noises etc). Nothing blocking the ducts too.
Anyone have any ideas to look into before either replacing the blower motor or upgrading the unit completely?
