Ensuring that you maintain your dryer is essential not only to ensure that it operates efficiently but also to use safely. One of the most critical maintenance tasks is to find a professional that provides dryer vent cleaning in West-Central Minnesota. 

It’s a good idea to have a professional that offers dryer vent cleaning come and inspect and clean out the vents and vent hoses. This is because a build-up of lint lessens the dryer’s efficiency and is also a fire hazard. If you’re one of the many DIYers that the Midwest so proudly hosts, then this is our guide for you. 

First, consider keeping your hoses short by positioning your vents near a wall.

One way that you can accomplish this is by shortening your dryer vent hose. 

A dryer vent hose is often longer than it needs to be for installation purposes. If this is the case, an excess hose can end up curling up behind the dryer, thereby preventing you from pushing the machine closer to the wall. 

This is also quite dangerous since the coiled ridges in a hose will trap dryer lint, which is more prone to heating up and catching fire. Measure the space between the wall and the dryer and cut the hose a few inches longer than you actually need to allow you to move the dryer out while installing the hose. The shorter the hose is, the more efficiently your dryer will run.

In most typical dryers, the exhaust opening is located on the back. Many homes will also have dryer vent exhaust openings cut into the wall behind their dryer; however, this can prevent a close fit since the dryer vent hose requires some space. Some dryers allow you to move the dryer exhaust to the side of the housing – have an electrician come to see if this is possible. Another option is to use a periscope vent pipe, which won’t trap as much lint due to its lack of ridges and which takes up less space behind the dryer.

Here are the best tips to avoid a dryer vent fire:

  • All dryer ducting must be a minimum of 4″ in diameter. Clean, free, frictionless ducts encourage airflow efficiency, quickens drying times, adds longevity to clothing’s life, and reduces utility bills.
  • The flexible transition hose between the dryer and the wall outlet should be either the foil type or the flexible aluminum duct (most preferred). Do not use plastic or vinyl.
  • Concealed ducting must be rigid metal (galvanized or aluminum) duct.
  • Duct joints shall be installed so that the male end of the duct points in the airflow direction.
  • Joints should be secured with metal tape (not duct tape). Do not use rivets or screws in the joints or anywhere else in the duct as these will encourage lint collection.
  • The length of concealed rigid metal ducting shall not exceed 35 feet (25′ for IRC). Deduct 5 feet from the allowable length for every 90 90-degree bow and two and a half feet for every 45 45-greeting. These lengths may vary per North Dakota and Minnesota building codes and dryer manufacturers’ recommendations.
  • Dryer venting shall be independent of any other systems (chimneys or exhaust vents)
  • Termination of dryer venting must be to the exterior with a proper hood or roof cap equipped with a backdraft damper. Small orifice metal screening should not be part of the hood or roof cap as this will catch lint and block the opening in a very short time. The hood opening should point down and exhibit 12 inches of clearance between the bottom of the hood and the ground or other obstruction.


Good Practices

  • Actually, inspect the termination port of the dryer and the wall or roof cap. Look for birds nest or clogged openings. Most importantly, feel for proper exit velocity of the air leaving the vent and look at or touch the duct’s interior walls.
  • If you suspect clogged or partially clogged exhaust ducting, you likely need to have them cleaned. Dryer vent cleaning improves safety and efficiency and should be cleaned or inspected every 6-12 months, depending on the venting circumstances.
  • Make sure your flex transition hose is not kinked or crushed. The space behind your dryer should be sufficient to provide adequate room for the flex transition hose to make its bends with minimal deflection and restrictions.
