Metal Ducts vs Flexi Ducts
Are flexi ducts are better or metal ducts are better in crawlspace for HVAC system. I see rats and package unit has these old metal ducts connected with big square hole on side which may be challenging to cover from rats to enter. I am thinking if i change metal duct to flexi duct then rats may chew right. please advise
