What is a good number reading for a furnace draft. Old system with old ductwork was -.01. New thermopride with new ductwork and a more straight smoke pipe now reads -.04 at idle.

Thanks. What would lining the chimney do.??? 2,000 to line a chimney seems pretty high which is a quote i have.

get other quotes, that is pretty high for most cases. lining the chimney will avoid unnecessary air infiltration and protect the integrity of the chimney.
