Local demand
The dryer vent cleaning market in Minnesota
Minnesota's long winters keep clothes dryers running constantly as outdoor line-drying becomes impractical for many months, allowing lint to accumulate and raising dryer-fire risk. The state's dense Twin Cities housing and many multi-unit buildings, plus rural homes far from quick fire response, all create steady demand for vent cleaning and safety service.

Curriculum
What you’ll learn
- Perform a full pre-cleaning inspection of the dryer, transition duct, and vent run to locate lint buildup, kinks, crushed sections, and improper materials.
- Identify and correct code-violating ductwork such as foil-foil flex, plastic transition hoses, and runs that exceed manufacturer length limits.
- Select and operate the right tools — rotary brush-and-rod systems, compressed-air whips, and HEPA vacuums — for the duct length, material, and routing.
- Measure airflow and static pressure before and after cleaning to verify the system meets performance targets and document the improvement.
- Safely access and service rooftop, sidewall, and shared multi-unit vent terminations, including replacing damaged or screen-clogged exterior hoods.
- Recognize the warning signs of a fire hazard — scorching, excessive drying times, overheating shutoffs — and advise the customer on corrective action.
