Jon B. was at our house today to clean our ducts. I'm not sure they have been cleaned in 18 years. There was a glitch with equipment breakdown, but Ductworks ran a new unit up to us asap. Tht stuff happens. Jon did a great job and was very personable. You have to be personable to be in someone's house for 6 hours. We were very pleased with the work product and the professionalism shown by Jon. Besides, he liked our dog, and the dog liked him. A good combination.
