Cleaning your dryer vent is a really good idea. In some cases you are able to clean your vent yourself and save money as opposed to having a professional do the cleaning. This is usually the case if you have a exhaust vent less than 5 feet long. You can buy a simple brush from a local hardware store and complete the cleaning.
The first thing to do is to pull out your dryer. Once you see where the connection is into your wall take apart the flexible hose that is usually found behind the dryer. Follow that opening to the exterior of your home and see where it is exhausting from. If in fact you are shorter than 5 feet long head to your local hardware store and purchase a dryer cleaning brush it is about $12 and it is affordable for most households. I myself go to Home Depot and they have it on aisle 13 at most of the stores I go to clean dryer vent.
Now that you are back at the house use the brush to gently push from the exterior of the home exhaust point back toward your dryer vent when your dryer is in the on function. You might want to be wearing a mask at this point. The lint that his built up within the duct line will be coming out pretty aggressively. Be sure to have a vacuum preferably a shop vac to clean up the lint as it exits.
Vent runs that are over 5 feet in length should be cleaned by a professional. at that point you have a higher degree of damaging your ductwork or injuring your self when it is greater than 5 feet. You might think that you can handle it but trust me I’ve seen some pretty banged up dryer vents from improper cleanings. Call a professional.
Now that you know that you have the ability to clean the dryer that is less than 5 feet in length you should be able to save yourself some money so don’t be afraid pull out the dryer and take a look at cleaning your dryer vent yourself.
