OK if cold air from condensate tube?
Central A/C unit located in attic. I had to unclog my primary condensate line when I noticed water accumulating in the pan that was coming from the secondary drain tube. Is it normal for cold air to blow out of those tubes? I assume the relatively small amount of cold air discharged into the attic doesn't amount to much, and to close it off would defeat its job of draining condensation. Am I missing something?
