The vent for my furnace does not have a cap and I can't find one to
fit it, or at least I didn't find one at Lowes and can't find one
on-line. It's one of those older type vents that is rectangular with
rounded ends, approximately 12" x 4". The canopy of a big oak tree is
over that part of the roof and I'm concerned that over time the vent
will get clogged with leaves and twigs.
I haven't been into an HVAC store yet, but the ones on-line do not
show anything that is that shape. Does anyone know where to get one?
Would it be ok if I just shaped a mesh screen and fit it overtop?
