    I was told by a HVAC service tech the incoming fresh air does not pass thru the air filter, only the recirculated air is filtered. I don't see how this can be since I only see one incoming air conduit to the HVAC unit passing thru the filter before entering the unit proper. Did I misunderstand the service tech? TIA Alex

    Do you have a vent that allows for outside air to enter your system?

    Yes. It is on the roof of a mutli-tenant condo building where the compressor is. I also have another condo that has an integrated wall unit so it draws air in directly to it.
