Moving Air Conditioning Ducts

Question: I have two air conditioning ducts bent in a 90 degree angle up in my attic. The room that they run to, of course, stays a bit warm. Can I just cut the ducts with a box cutter, re run in a straighter path and duct tape them back?

Answer: It might change the air balance throughout your home. If you do make the change make sure you use tape made for ducts - NOT the grey stuff you buy at your local big box store - that is not made for taping ducts together.
