  • Siding – Cutting a vent hole through vinyl or wood costs less than cutting through brick or stone.

  • Complexity – Duct elbows and complex ductwork configurations increase material and labor costs.

Dryer vent installation FAQs

How long can a dryer vent be?

A dryer vent can be up to 35 feet long maximum if it’s straight. Elbows in the ductwork or rooftop venting require a shorter vent length. Inspectors allow exceptions based on dryer-manufacturer recommendations. A booster fan is necessary for extra-long ducts.

How long does it take to install a dryer vent?

HVAC pros take 2 to 4 hours to install a new dryer vent where one didn’t exist before. Professionals can replace a pre-existing dryer vent in one hour in most cases. Extended timeframes are necessary to cut new holes in brick or stone siding.

Do you have to vent an electric dryer?

Yes, you have to vent an electric dryer. If moisture cannot exit the system, then clothes stay wet and encourage mold growth. Lint builds up inside the dryer and creates a fire hazard.
