WOW! Our ducts hadn't been cleaned in at least 20 years, probably longer. We've have dogs and cats, we've sanded wood floors and sheetrocked . . . you get the picture. What Jon cleaned out of our duct work and furnace was so atrocious, and he was utterly cheerful about it! He turned the furnace fan on while he worked to get as much air flow as possible, and used a super shopvac with a spinning brush on the end and a long hose. Then he used a sanitizing system. We can totally feel the difference right now, and he just left. It's like the house can breathe again. Why didn't we do this decades ago???? Jon was so thorough and very knowledgeable about how to keep things maintained from here on. We could not be more glad that we did this. Thank you, Jon!! read more
