make up air
I've got to have an HVAC guy add make-up combustion air to my fha furnace.
This is a requirement from the local building inspector.
I had a guy come buy and recommened a 'fan in a can'. Couple of
questions...what are these -and- how much do they cost to install?
I can't seem to find something titled 'fan in a can' with google.
thanks.
