Community Tips
Rigid metal duct must be supported every 12 inches with vent clamps to prevent sagging, which traps lint and creates serious fire hazards -- undersupported ducts can accumulate flammable debris within weeks even with regular cleaning. Never substitute flexible aluminum accordion duct for rigid ductwork, as it collapses under negative pressure and voids most dryer manufacturer warranties.
A Milwaukee M12 Cordless Drill ($70-110) with a 1/4-inch hex drive bit attachment makes securing vent clamps 60% faster than manual screwdrivers and prevents the stripped screw heads that commonly plague this job on existing installations. The compact design fits easily in tight spaces behind washers and dryers where hand tools typically bind.
Upgrading to insulated rigid metal duct from brands like Lambro Industries ($25-40 for 8-foot sections) costs 15-20% more than standard galvanized alternatives but reduces heat loss by 30% and cuts drying times by 10-15%, offsetting the material premium within 1-2 years on average household usage. ---
