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.

"On estimate
Rich was prompt, friendly and professional. He was straight with me and honest.
Another HVAC company told me I had to install pumps to each unit (I have 3) to help the flow of water (a total of $600). Rich explained to me that all that was needed were some "T" pvc for venting ($0.39 each) that he had on hand. Since it was a quick task, he put them in for free.
He gave me a price that was $1,200 LESS than another estimate.
On the work
He called the day before letting me know the weather looked bad on the day of the install - depending on the weather, he might have to do it the following day. I really appreciated that notice given I have tenants. It was very professional.
When the weather was better, he showed up- as promised - and he kept in communication with me.
A few hours after he left it wasn't cooling the apt. We chatted by text even though it was late. He came out the next day without complaint and fixed the problem. All the while keeping me informed.
Overall
Although the install was a bit bumpy, he never complained, was considerate, easy to work with and treated me very well.
He has earned a customer for life.

"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."

"This is the second time we have used them, and we will use them again. Eric and his guys did an excellent job. They are thorough and professional. Carpets looked great and our dryer vent got a much needed cleaning. These are honest, helpful people who do a great job at a fair price. Highly recommend."

"Doug and his assistant (don't remember his name) were very professional. They were nice to my "scaredy" dog too. They showed me the before and after pictures of my duct work when they were done and it was the difference between night and day."
