I had an awesome experience with Josh and his Duck Squad Company - set the appointment on a Wednesday, and he was able to come by Friday. I had purchased a new dryer and noticed that the 'check vent' light (red) was on, coupled with an AF code indicating there was an air flow problem. Since I had spent quite a bit on the dryer, I expected the 'good air flow' (green) light to be on! I contacted Lowes and they delivered me a new dryer, however same problem!! I knew then it was my vent problem and not a dryer problem. That's when I contacted Josh with Duck Squad. He was very personable and professional, even allowing me to lurk over his shoulder so I could see the mess he extracted from my dryer vent. Through discussion, it was clear that Josh is a family man and cares about conducting good business. And that he did! The green light is on and my drying time has significantly decreased! My only regret, is that I waited this long to get it cleaned and how much time, money, and energy was wasted from not doing so earlier. Thanks so much Josh and Duck Squad! I highly recommend!
