It’s not unusual to open things up at the start of the season and find a tear, puncture, or possibly a few chew marks, leaving the exhaust hose a whole lot less effective. Whether you’re installing a hose for the first time on a new AC unit or swapping out a damaged one, follow this easy guide to replace an air conditioner exhaust house yourself.
