There are two different cleaning jobs.
Lint-filter care belongs with every load. Exhaust-vent cleaning follows a separate schedule. Your dryer's manual, how it is used, and changes in performance should guide that schedule. A clean lint filter does not prove that the concealed route to the outdoors is clear.
The U.S. Fire Administration advises cleaning the filter before and after each cycle and having dryers professionally installed and serviced. Read its clothes dryer safety guidance (PDF).
With each load
Follow the model's lint-filter instructions. Keep everyday laundry items and clutter away from the dryer.
For the exhaust route
Use the interval in your appliance manual and any recommendations from an assessment of the actual setup.
If performance changes
Arrange appropriate assessment instead of waiting for the next planned cleaning date.
For context, Whirlpool's general maintenance guidance describes exhaust-vent cleaning every one to two years, or more often when drying performance declines. It also says use and the items dried can change the interval. That is manufacturer guidance, not a universal schedule for every home or dryer. See Whirlpool's dryer upkeep guidance.
If you have moved into a home and do not know the service history, start by checking the appliance instructions and any available maintenance records. “Last cleaning unknown” is useful information when you request an assessment; it does not, by itself, establish a blockage.
Do not let a calendar override a changed dryer.
Clothes that remain damp after a normal cycle or drying that takes unusually long can indicate a lint-screen or exhaust restriction, according to the Consumer Product Safety Commission. Other causes are possible too. Read the CPSC dryer safety alert (PDF), and see our guide to a dryer taking two cycles.
A visible loose, damaged or compressed connection deserves its own review. Exposed connection work and appliance repair are different from cleaning the exhaust route. Do not run repeated cycles to test a suspected restriction. Follow the manufacturer's directions and stop using an appliance that appears unsafe.
Describe what you already know. There is no need to move a stacked dryer, disconnect a hose, open the appliance or climb onto a roof to make an enquiry. This website is not an emergency response service.
A checklist to keep with your maintenance records.
Use your browser's Print option to save or print this page. These details make a cleaning or access conversation more useful; unknown answers are fine.
- Appliance: make, model and where its instructions are kept.
- Last known vent cleaning: date, who did the work and any recorded limitations.
- Current concern: routine maintenance, slower drying or a visible connection issue.
- What changed: when it began and whether it affects every load.
- Known exit: outside wall, roof or not sure.
- Laundry setup: floor, stacked or side-by-side, closet and known access limits.
- Permission and access: who can authorize work and provide entry. For a rented home or shared building, confirm the appropriate owner or manager first.
- After service: retain the agreed scope, work completed, remaining concerns and recommended next review.
Keep full addresses and personal contact information in your own records. An initial enquiry needs only enough information to discuss the setup and follow up.
Ask what the cleaning includes.
Before agreeing to work, confirm the route and access points to be addressed, whether appliance movement is needed, and how any exposed connection issue will be handled. Ask what happens if a section cannot be reached. A vent-cleaning request should not be assumed to include internal appliance service, gas or electrical work.
Keep cleaning, connection repair, materials and access-related work distinct in the estimate. Our cleaning-cost and access guide explains the questions that shape the scope and charges.
Discuss maintenance for your Centennial home.
Centennial Vent Care reviews residential cleaning and accessible connection enquiries within Centennial city proper. Wall exits are the starting focus; roof access and difficult setups need separate review. Tell us what is known about your vent and its maintenance history. We follow up about availability and next steps, with scope, charges and timing confirmed before you agree.
