Sonic responded to my quote request almost immediately. They were able to schedule a duct and dryer vent cleaning 2 days later. Troy arrived as scheduled (with many text updates in advance of the appointment) and did a thorough, professional job. He was extremely knowledgeable and friendly. We are really pleased with the quality of the work and the price was good (I obtained other quotes to compare). I highly recommend Sonic and will absolutely use them again!!
