Blueballs is actually just another disgruntled reject that was charged
over $100 on a weekend to change his own dirty filter because he was
too lazy and stupid to do it himself. Probably due to the fact that he
is too fat to step away from the keyboard judging from the amount of
blithering posts he has made.
Nice and warm here buddy. Have a nice time replacing parts.

Are you actually recommending that a homeowner replace their own filter?
My God, man, it's a FURNACE! IT COULD BLOW UP! It's got VOLTAGE! You
could get ELECTROCUTED!
