"Tim actually answered his phone when I called him! He came the same evening and looked at my attic fan and gave me a quote. He came back in 3 days and exchanged the fan in less time than he quoted and was very courteous He even vacuumed the carpet and took the old fan and trash away with him. Very professional ."

I am a jack of trades independent contractor/ handyman with 10+ years experience. I am not a licensed plumber, licensed electrician, or licensed roofer. With that said it's easier to just tell you the things that I don't do. I do not do drain work, I do not replace electrical lines or panel boxes, I do not replace plumbing lines which includes water and gas, and I do not replace roofs. Aside from that I can do everything else, and have the tools to do so.

"Prompt, professional, courteous. Seemed to do a great job, showed before and after pix."

"On April 30, 2025 we utilized the services of Duct Dusters, Springfield, IL to clean our ducts prior to an installation of a new HVAC system. We selected Duct Dusters because they are BBB Accredited, had a 5-Star rating, great reviews, & the owner, Jeff explained their cleaning processes in great detail. Our technicians, Max & Cody arrived on time; were friendly & professional; wore booties over their shoes; showed us before-during-after pictures of each duct; and left the premises tidy & free of debris. They deserve our 5-star rating."

"Amazing service! They cleaned our ducts and greatly improved not only the efficiency of our AC system but also the air quality"
