Dryer Vent Cleaning

Most homeowners do not realize that dryer vents need to be cleaned!

Dryer Vent CleaningLint build-up in dryer vents is an extreme fire hazard

Notice the lint build up. This is a fire waiting to happen!

As you may already know from cleaning out your lint trap, dryers produce very large quantities of lint. Most homeowners assume the lint trap catches all the lint, and all we need to do is clean it out after each load. Not True... It is recommended that dryer vents be professionally cleaned at least once a year.

Traditionally, most clothes dryers were located in the basement of a home. Today many newer homes tend to have dryers located on the 2nd floor in a bedroom, bathroom, hall, closet or kitchen. Because of the newer locations, dryers tend to be vented longer distances. Longer vents are generally installed with sharp turns and bends to accommodate the structure of the home. As a result, dryer vents are harder to clean and have more places for lint to gather.

How Lint Accumulates

A full load of wet clothes placed in a dryer contains about one half gallon of water. As water is removed, lint is created from the clothes. Each time you use your dryer, lint builds up more and more. When the lint build-up is too much, it causes the dryer to work harder resulting in higher operating costs and increased repair bills. Did you know one-half inch of lint build up in a 4" diameter duct reduces its efficiency by 44%? A dryer is the most expensive appliance in your home to operate, you don't want to make it more costly than it already is.

Safety Recommendations

Dryer Vent CleaningMany insurance companies are now mandating that dryer vents in condominium complexes, town houses and other facilities be cleaned, and repaired if necessary, to reduce any risk of fire. In many cases this includes the replacement of white vinyl plastic coated flexible venting with metal duct work. While most building codes require metal ducts we recommend that you avoid using the metal foil covered flex types as well. Metal foil covered flex is a little easier to install but can reduce air flow due to its corrugated design and will contribute to lint buildup in the ducting over a period of time. Even worse, flex ducts can become crushed or curled up on the floor behind your dryer which blocks air flow and cause your dryer to over heat which can cause a dryer vent fire. The more bends in your venting the greater the reduction in air flow and more areas where the lint can accumulate.

Some home owners think it is acceptable to vent the dryer indoors if it is a large open room. There are several reasons this is not a good idea. In the first place, most building codes prohibit this type of venting. This extra humidity released from you dryer is exactly the tropical climate that mildew thrives upon and will eventually condense on installation, timbers and metal, causing them to deteriorate, rot or rust. Never leave your house or go to bed with your dryer running!

Most of our customers call when they no longer have air flow and the dryer is taking much longer to dry a load of clothes. Dryer vent cleaning should be performed yearly and if you use your dryer daily you should consider a seasonal cleaning.

Our Process

DuctPro uses the RoVac system which is the most advanced equipment of its type. Using a combination of suction from a high powered vacuum and rotating brushes, the lint build-up is removed safely and effectively. Our system also contains the specialty tools needed to remove blockages such as birds nests.

DuctPro urges you to get a professional dryer vent cleaning if:

  • If your dryer vent has not been inspected or cleaned in over a year
  • If you have a large family and use your dryer daily
  • If you have white vinyl plastic coated flexible venting. This is no longer code-approved as burning lint can ignite in less than 12 seconds
  • If your dryer vent has thin metal coated foil flex venting. If crushed or left curled behind your dryer this will stop air flow
  • If your dryer is still heating but it is taking longer to dry a load of clothes (longer than 45-55 minutes to dry)
  • If clothes are still damp or hotter than usual at the end of the drying cycle
  • If clothes have a moldy smell after a dry cycle
  • If the outdoor flapper on the hood vent does not open and close when the dryer is on

DuctPro offers dryer vent cleaning, bird nest removal, and dryer vent repairs on residential homes, apartments, townhouses, condos and duplex's.
