Dryer Takes Too Long to Dry

Related service: Dryer Vent Cleaning

Quick Answer

A dryer that takes two or more cycles to dry a normal load almost always has a clogged or restricted vent line. Lint buildup reduces exhaust airflow, trapping moisture inside the drum and dramatically increasing drying time. Professional dryer vent cleaning restores airflow and can reduce drying time back to a single cycle, saving energy and reducing fire risk.

Common Causes

Gradual lint accumulation inside the vent line restricting airflow
A long vent run with multiple bends that slows airflow and traps lint
A crushed or kinked transition hose behind the dryer
A blocked exterior vent cap from lint, debris, or animal nesting
Using flexible vinyl or foil duct instead of smooth rigid metal

Is This Dangerous?

While a slow-drying dryer may seem like just an inconvenience, it signals restricted airflow that carries real safety risks. The excess heat generated when a dryer works overtime against a clogged vent accelerates wear on internal components and can push temperatures to dangerous levels. Lint trapped in an overheated vent can ignite. Long drying cycles also mean significantly higher energy consumption — a clogged vent can increase energy usage by 30% or more. For gas dryers, poor venting can cause carbon monoxide to back up into the laundry room instead of exhausting outside.

When to Call a Professional

Call a professional if your dryer consistently takes longer than 45-60 minutes to dry a standard load, if you have not had the vent cleaned in over a year, or if you notice the dryer or laundry room getting excessively hot. Also schedule cleaning if the exterior vent flap barely moves when the dryer runs or if you see lint accumulating around the dryer connection. Even if drying time has increased gradually rather than suddenly, the vent needs attention — gradual restriction from lint is normal and expected, which is why annual cleaning is recommended.

How Professionals Fix It

Professionals use commercial rotary brush systems designed to reach the full length of the vent run, no matter how long or how many turns it takes. The brush loosens compressed lint from the vent walls, and powerful vacuum extraction removes all debris. The technician checks every component: the transition hose, wall connection, entire vent run, and exterior cap. Airflow is measured before and after to quantify the improvement. If the vent uses improper materials or has an excessively long run, the technician will recommend modifications to prevent future issues.

Cost Estimate

Standard dryer vent cleaning costs $89-$250. If vent rerouting or material replacement is needed, expect $150-$500 depending on complexity. The energy savings alone from restoring proper airflow — up to 30% reduction in dryer energy use — typically recoups the cleaning cost within a few months.

Frequently Asked Questions

How long should a dryer take to dry clothes?
A standard load of clothes should dry in 30-45 minutes on a properly functioning dryer with a clear vent. If your dryer regularly takes 60+ minutes or requires multiple cycles, the vent is likely restricted.
Will cleaning the vent really make my dryer faster?
Yes. In most cases, a professional vent cleaning immediately restores drying times to normal. When the vent is clear, hot moist air exhausts efficiently and clothes dry in a single cycle. Many customers report dramatic improvement the very first load after cleaning.
My dryer is new — why does it take so long to dry?
Even a brand-new dryer will perform poorly if the vent line is clogged. The vent is part of the home infrastructure, not the dryer. If a new dryer takes too long, have the vent cleaned and inspected before assuming the dryer is defective.
How much extra energy does a clogged vent waste?
A clogged dryer vent can increase energy consumption by 30% or more. Running multiple cycles doubles or triples the energy used per load. Over a year, this can add $100-$200+ to your utility bills, making annual vent cleaning a worthwhile investment.
Does the length of the dryer vent run matter?
Yes. Longer vent runs and additional bends reduce airflow and trap more lint. Most building codes allow a maximum of 35 feet, with deductions for each elbow. Homes with long vent runs need more frequent cleaning — often every 6 months instead of annually.
