I called Dryer Fires to come clean my dryer vent after having numerous problems with my brand new dryer. My new dryer wasn't working well and they even sent me a replacement dryer saying mine was defective. I had asked the dryer company if my vents could be the issue and they checked my vents and said they were clear. After the 2nd dryer had the same issues I took matters into my own hands and called David. He surprised me by coming out the same day and it was a Saturday! He got my vent cleaned out and removed something on my roof that was blocking the air flow. Now my dryer is working perfect. Thanks David!
