Is there a maximum allowed length for a dryer vent duct, and what happens if mine is too long?
Most manufacturers and building codes allow a maximum of 25 feet of rigid metal duct for a dryer vent, with that length reduced for every elbow or bend in the run. In many Phoenix homes with laundry rooms in the interior of the house, we find vent runs that exceed safe limits — which traps heat and lint and strains the dryer. Call Pure Air Service at (623)552-3176 and we’ll measure and evaluate your vent run to make sure it meets safety standards.
