Inspected the air ducts but told me I didn't need them cleaned. He also cleaned the dryer vent and tunnel and gave advice about placement of the dryer vent being so close to the air conditioner. He also cleaned and inspected the air conditioner. The service man was so very nice and professional. He gave me lots of information and guaranteed his work. He is very close to my address in Bloomingdale and I would have no hesitation in calling him again.
