"He came out within about 2 hrs of me calling, which was great. He cleaned everything, replace freon, and advised me on how to handle future problems. The best thing was he did not try to sell me a new unit. All of my HVAC equipment in my house is older, and anytime I have had anyone else over for any reason they always try and sell me on new furnace/AC etc. He did not. He was quick and professional and it was appreciated. I will definitely use and recommend him in the future.

"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."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."
