I noticed quite a large opening (8" x 8") in the cold air return going into
my furnace in my basement.

It's been missing a while, and it's in a ackward spot to fix.

What is the prblems associated with this hole, and what improvements will I
gain by spending the time to fix it (seal the opening)?

Thanks


Not be scare you, but you should have your basement/house tested for
Radon. If you have elevated radon levels, you DEFINATELY want to have
it fixed. You don't want to blow that into your living space. If
not, it's no big deal.
