Hello! I purchased a ranch home last year. It has central air and a high-efficiency nat gas furnace (Lennox).
I have two white PVC pipes coming through my brick on the back side of the house. They are about 2" in diameter and are unbelievably unsightly. I imagine one is an inlet and the other exhaust. Overall, they're probably 6' in length and include a couple of 90 deg bends each.
Is there a certain length restriction requirement for these pipes? Can I cut/shorten them?
I have photos, will upload when I arrive home from work.
Thanks for any help!!!
