Unfortunately, dryer vent cleaning is a neglected maintenance item in most homes. Here in Arizona the dryer venting in most cases goes through the roof. Without some sophisticated equipment to run a camera up to the roof you cant really tell if this is a necessary expense. Our dryer vent cleaning costs are $135 for a single story home and $185 for a two-story application. One of the early signs of a clogged wall vent is dry time. When it starts to take far longer than it used to then it might be necessary. Call us at 602-412-3133 to speak to one of our experts about setting up a consultation.
