"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

"They are the absolute best in the area. They had to order a part and still got the job done in under 8 days. Calvin had great communication line telling me exactly what needed to be replaced and the status of the job. They will be taking care of all of my future HVAC needs. Best company in the Springfield area!!"

"After a scorching week with temps hovering in the upper 90's, I didn't think I would be able to get anyone here so quickly. I called Bob on a Saturday morning around 8am, and surprisingly enough, he was able to be here within a few hours. I explained the problem and he answered all of my questions. Lucky for me, I only needed freeon. Seems to be working. He was informative, friendly, and someone I felt I could trust. His prices were reasonable, too. I would recommend him to anyone. In fact, I have his receipt on my fridge waiting for the fall, so he can come out and inspect my furnace to make sure I'm good for the cold weather. It's sure nice to know there are people still around that are honest and just not after your last buck! Kuddos to Bob!"

"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."
