Fantastic process start to finish. First visit from Brett quoted me what I wanted and offered more with some additional options since there were some rebates available. Communication was top notch. And they solved some air flow issues we had. One hiccup under the house but that issue was resolved and fixed with mutual understanding. Thanks to the crew of four that helped this 50 year old house get an update.

I had my air ducts cleaned Capitol Duct Cleaning’s tech(s) Daishaun N. And Lucas B. They were a group of young professionals who did an outstanding job. They took the time to explain what they were doing as they worked. I appreciated that as a customer. They were both patient with all my questions. I will definitely use them again. It was a great experience.

Dominick was on time for duct cleaning, respectful of my home, and very thorough. He answered every question to my understanding and explained every detail. I am happy with the service, and have already recommended Capital Duct Cleaning to my friends on the same day. The charge is below of their competitor’s’ bids.

Brett with Capital Duct Cleaning installed a 4-in filter box on our furnace. Once again, he was highly skilled, fantastic with sharing information and educating us, very thorough with craftsmanship and cleaning up afterwards, and very kind. I would highly recommend this company for all kinds of work on furnaces, after hour two experiences with them. I'm already recommending them to friends and neighbors.

The woman at the office that gave me my estimate was incredibly nice and very helpful. Setting up the service was equally pleasant. Dominick was our service tech and he was very polite, friendly, and informative. He informed us at every step how things were going and what the next step would be. Would highly recommend!

I had an excellent experience with Capitol Duct Cleaning! Larry and Q were fantastic—professional, friendly, and extremely thorough. They took the time to explain everything they were doing, showed me before-and-after photos, and made sure the entire system was cleaned perfectly. You can tell they take pride in their work. My home already feels fresher, and the airflow is noticeably better.

I highly recommend Capitol Duct Cleaning, especially if you’re lucky enough to get Larry and Q. Outstanding service from start to finish!

Every single person I spoke to from Capitol Duct Cleaning was fantastic. The person I talked to on the phone to schedule was very nice and encouraging and the technicians (Ross, Quintin and Larry) that came out were very helpful especially considering we didn't know much about the history of our house regarding duct work. They were able to get everything cleared out and cleaned out quickly and were very kind and personable while doing so!

I highly recommend this company!

Response from the owner 23:15 07 Nov 25

Thank you so much for your kind words! We're thrilled to hear that you had such a great experience with our team. Ross, Quintin, Larry, and our scheduling staff will be so happy to know they made a positive impression. We’re glad we could help get your ducts cleaned and everything running smoothly. We truly appreciate you choosing Capitol Duct and taking the time to share your experience!

Dryer duct was completely clogged. They came out the day after I called and had it open in an hour for what I thought was a reasonable fee. I will use them again.

Russ was on time and went to work! We had never had our air ducts cleaned previously. Based on the dirt built up in the blower motor we just had cleaned, it seemed logical to have the ducts cleaned as well. I was somewhat skeptical of the need to have it done but was pleasantly surprised by all the grime in the return air ducts. Not cheap but they did an A+ job!

Response from the owner 20:35 05 Nov 25

Thank you for sharing your experience, Mark! We’re glad to hear Ross took great care of you and that you were able to see the difference in the return duct system. It’s completely understandable to be unsure at first, especially if the ducts haven’t been cleaned before — we’re happy the results spoke for themselves. We truly appreciate the trust and the opportunity to help improve your home’s air quality. Thank you again for choosing Capitol Duct.

I would highly recommend this duct cleaning company! I truly appreciate the technician, Quintin, who came to my home—he did an outstanding job. From the moment he arrived, I could tell he was very professional. He wore shoe covers and brought high-quality, efficient equipment that provided a deep and thorough air duct cleaning. He also shared helpful knowledge and before-and-after pictures with me, which I really appreciated.

I also want to thank the front desk team, especially Amy and her co-worker. Because of my kids’ school event, they went out of their way to accommodate my schedule. I can’t thank them enough for their flexibility and kindness.

Overall, I’m extremely satisfied with the service. Highly recommended!

Absolutely outstanding service!
The team came out to clean our ductwork and dryer vent, and they did a thorough, professional job from start to finish. They were polite, genuinely friendly, and took the time to explain every step of the process, answering all our questions with patience. They also sanitized the system and gave helpful, non-pushy recommendations for maintaining clean indoor air. We immediately noticed a difference in air quality. Highly recommend!
