I was very pleased with my visit from Airtime Climate Control to clean my dryer vent. Keltson was the technician. He was very professional and did a good job cleaning the vent and removing an obstruction on the roof where the dryer was vented. My dryer had not been drying as it should. After Keltson left I washed a load of towels and when I dryed them, the drying time was cut in half of what it was before. I would recommend this company to anyone needing their dryer vent cleaned.
