The time and effort DuctDudes put into the job greatly exceeded expectations. The furnace has never been this clean, and the air in the home feels much cleaner, which is great for helping with allergies. Jason and crew were friendly (great senses of humour) and professional to deal with. Thanks for the respect for the pets and others in the house. (BTW…Zeek the cat has forgiven you for not rubbing his belly, as he saw that as professionals, you had other things to focus on, but he enjoyed your attention just the same – two purr paws up.)
