Lint screen

The small mesh filter inside your dryer door that traps loose lint before it enters the dryer exhaust duct. Atlanta homeowners often overlook cleaning this screen monthly, but a clogged lint screen forces your dryer to work harder—raising energy bills and fire risks. Pro tip: Clean it after every load—especially in humid months when lint sticks faster

Lint buildup

The dangerous accumulation of flammable lint inside your dryer vent or duct, often caused by skipped cleanings or improper venting. In Atlanta’s damp air, lint can mold or even ignite if ignored. Signs include long drying times, hot dryers, or musty smells. Learn how often you should clean your vent

Dryer exhaust duct

The ductwork that funnels hot, lint-laden air from your dryer to the outside. Many Atlanta homes rely on semi-rigid duct or rigid metal duct, but kinks, sharp turns, or crushed sections choke airflow and trap dangerous heat. Check our repair guide for fixes

Rigid metal duct

A durable, straight dryer exhaust duct made of aluminum or galvanized steel, preferred for Atlanta homes because it resists crushing and corrosion from humidity. Unlike flexible ducts, it won’t collapse over time, ensuring steady airflow. Ask us if your duct needs upgrading during your next cleaning

Semi-rigid duct

A middle-ground dryer vent option with a flexible outer layer and a rigid inner core, designed to reduce kinks. Atlanta pros often recommend it for tight spaces, but it can still degrade if exposed to sunlight or moisture. Compare duct types in our comparison guide

Transition duct

A short connector piece that bridges different duct sizes or materials (e.g., from flexible to rigid metal duct). In Atlanta’s older homes, these are often overlooked during installations, creating weak points where lint collects. Schedule a full vent inspection to check for transitions

Wall vent hood

The wall-mounted vent flap where dryer exhaust escapes. Atlanta’s summer storms can warp or damage these covers, cutting airflow. Watch for rust, gaps, or nests—clear signs it’s time for a deep clean or swap. See East Point repairs

Roof vent cap

The exterior vent opening on your roof, often fitted with a bird guard to prevent nests. Atlanta’s heat and rain can warp these caps, trapping lint inside. If your dryer runs hot or smells like gas, the cap may be blocked. Learn DIY checks in our blog

Backdraft damper

A flapper valve inside your vent that closes when the dryer isn’t running to block cold air from entering. In Atlanta’s humid climate, dampers can stick shut, forcing your dryer to overheat. If you hear rattling or feel weak airflow, it may need lubrication or replacement. Book a pro to service yours

Bird guard

A mesh screen installed over roof vent caps or wall vent hoods to stop birds from nesting in your dryer vent. Atlanta’s urban and suburban areas attract sparrows and starlings, which can clog vents with feathers and debris. Add one during your next cleaning

Airflow

How well air moves through your dryer exhaust system. Weak airflow in Atlanta’s humidity forces your dryer to overwork, draining energy and raising fire hazards. Test it: hold a tissue near the vent—if it barely moves, your vent’s likely blocked. Get airflow testing rates

Maximum duct length

The ideal distance your dryer vent should span from the dryer to the exit (typically 25 feet or less). Atlanta’s larger homes often exceed this, forcing dryers to struggle. Every extra foot reduces airflow, so keep runs short and straight. Ask us to audit your duct length

Duct elbow

A 90-degree bend in your dryer exhaust duct, which can trap lint and restrict airflow. Atlanta’s older homes often have too many elbows, slowing drying times. Limit elbows to 45 degrees and keep them smooth. See our repair guide for fixes

Booster fan

An optional fan installed in-line with your dryer vent to improve airflow in long or poorly designed vents. Atlanta’s humid air can make booster fans a smart upgrade for homes with weak natural ventilation. Learn if you need one during your inspection

Recessed dryer vent box

A built-in vent cover that sits flush with your wall, often used in Atlanta’s modern homes for a cleaner look. These can hide clogs or damage behind drywall. If your dryer runs hot or smells musty, check for lint buildup behind the box. Schedule a cleaning to inspect yours

Static pressure

The resistance your dryer’s motor faces pushing air through the dryer vent. High static pressure in Atlanta’s heat often means a clogged vent or kinked duct. A professional can measure it during a dryer vent cleaning to pinpoint blockages. See our pricing for diagnostic tests
