Dryer Booster Fan Installation.
If your dryer duct runs over 35 feet, has multiple bends, or your dryer takes two cycles to dry one load — your built-in fan can't keep up. An inline dryer booster fan restores airflow, shortens drying times, and dramatically reduces the lint buildup that causes vent fires.
The Benefits You'll Notice
Shorter Drying Cycles
Stronger airflow pulls moisture out faster — one cycle dries one load instead of two.
Lower Energy Bills
Less runtime on your dryer means real savings on electric or gas every month.
Reduced Fire Risk
Lint can't settle in a duct moving air at proper velocity — far less buildup, far less hazard.
Longer Dryer Life
Your dryer's motor and heating element stop fighting a clogged, undersized duct run.
Auto On/Off Operation
Pressure-activated fans switch on the moment your dryer starts and stop when it ends — zero user input.
Solves Long Runs
Designed exactly for runs over 35 ft, multi-elbow paths, attic routes, and second-story laundry rooms.
What to Expect on Service Day
Measure & Inspect
We measure the total developed length of your duct, count elbows, and confirm a booster is the right fix — not just a cleaning.
Install & Wire
We mount the inline booster mid-run, seal connections with foil tape (never screws inside the duct), and wire the pressure switch.
Test & Verify
We run your dryer, confirm the fan auto-activates, and take a before/after airflow reading so you can see the gain.

Frequently Asked
How do I know if I need a booster fan?
If your duct run is longer than 35 feet, has 3+ elbows, runs uphill into an attic, or your loads regularly take more than one cycle to dry — you're a candidate. We confirm with an airflow reading before recommending one.
Do I have to turn the fan on manually?
No. We install pressure-activated booster fans. The fan senses airflow from your dryer and turns itself on and off automatically.
Will a booster fan replace my dryer vent cleaning?
No — and we always clean the duct first. A booster pushing air through a clogged duct just stresses the motor. Cleaning + booster is the right combo for long runs.
Is this safe for gas dryers?
Yes, when properly sized and installed mid-run with sealed connections. We follow IRC and manufacturer guidelines for both electric and gas dryers.
How long does installation take?
Most installs are completed in 1.5–2 hours, including duct cleaning and airflow testing.
