Answered all our questions in such a professional manner. Did not try to upsell. He took time to show us pictures of what was done and explained the process. We had concerns about the length of the venting and duct work in the back of our dryer and he assured us that what we had was working fine.

I hired Capitol Duct Cleaning to clean a dryer vent in April 2025. Fourteen months later, when the dryer started malfunctioning, an appliance repair technician found the cause: a cleaning brush lodged in the duct. I don't know how or when the brush ended up there — but I do know that a thorough duct cleaning should have found and removed it, and Capitol's did not. When I called to raise this, they denied any responsibility and offered excuses for why their air-hose method wouldn't have caught it — while refusing to remove it now except as a new, separately paid job. Whatever the brush's origin, their original service demonstrably failed to clear the duct. I agreed to pay again anyway, just to get it resolved. I was told a manager would call me first to discuss it. No one called. I waited for the scheduled technician instead; no one showed. When I followed up, I learned the office had canceled the appointment without telling me. I rescheduled a third time, and to avoid any confusion, I emailed a photo of the brush along with the access details (about 10 feet in, no crawlspace) and asked them to confirm they could do the job at the agreed price. The email went unanswered. When I called, I was assured the office had seen it, reviewed the photo, and confirmed the job and price. Two weeks later, the technicians arrived — 90 minutes early, before I was ready — with no idea they were there to remove a stuck brush. After using about 15 minutes of my time, they concluded they couldn't remove it after all. I told them to leave and hired someone else. Across three separate appointments and every point of contact — the initial cleaning a year ago, the manager callback, the scheduled visit, the confirmed job — Capitol Duct Cleaning did not follow through on a single commitment it made. I won't use them again.

They went above and beyond for us. My husband was recently diagnosed with lung cancer. They installed an air scrubber in our HVAC system. It took about 30 minutes for them to install. All the way around, the staff is amazing. Extremely friendly and customer service oriented. Will definitely be using them in the future for the cleaning of our duct system.

It's easy to write a 5-star review when everything goes perfectly. Giving a 5-star review when there's a challenge? That's a good company, and that's where I'm at. In general, every person I've talked to or had out has been kind, courteous, knowledgable and really stepped up. For example, my air return wasn't installed quite right (tract homes), and the tech went and reworked the sheet metal and fixed a problem that was not even theirs. Just free of charge, just pride in work stuff. Then we all learned that the builder didn't tighten the wires into the control board, so the cleaning vibrated it out and my heat pump went offline. Same time, a burning dust smell in a bathroom kind of lingered (builder left vents open/running during construction.) This time, the head dude himself comes out, they hook it all up, re-clean the entire system for good measure, and my price? Zero. They just did it. I'll say too, I'm not an HVAC guy but I've worked around construction enough to know when people care, and I'm telling you, these guys are the people you want working on your house.

Should’ve done this sooner! Our dryer wasn’t working nearly as efficiently as it used to. We called them to see how soon they can stop by to clean the exhaust vent. They were able to come by on the nest business day (called Friday, saw them Monday). I wasn’t sure where our vent was located so they charged the higher price up front (in case it was on the roof) then when they realized it was ground level they refunded the difference! Lucas B. and Daishaun N. were the 2 technicians to do the work and I love that in my invoice it shows the photos they took and the sensor they use to show how much more air can now freely flow through. I didn’t know this was a maintenance thing! I’ll make sure to do this yearly now so this type of blockage won’t happen again. Thanks guys!

I give them a 5-star--with some reservations. First, the good: Both Dominick and Quentin, the techs, were great. Very polite and thorough. And Adam, the owner, was very nice and quickly addressed my concerns when the work I expected wasn't done during the first visit. Now, the not-great: I initially called for professional dryer vent cleaning when I saw lint build-up beyond my lint filter and couldn't reach it with my vacuum. But I quickly learned from the first tech that cleaning from the dryer's lint filter to the wall isn't included in their service. For an industry whose entire existence is based on the threat of dryer lint building up and causing a fire, it's weird to me that this business only addresses PART of the threat. When I spoke with the owner about this, to his credit, he eventually agreed to send a second tech out to provide that service at no extra charge. The other bad is not that it took 4 business days to get this resolved, as I think that's a pretty reasonable timeframe. No, it's the fact that I've received 3 texts and 1 email since the 1st visit begging for a review. I don't need to be hounded daily (esp before the work is complete) to provide a review. And I don't need to be told that the techs' bonuses depend on getting a five-star review. In the end, the work was performed well and the price seemed reasonable. But the bumps along the way were annoying.

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.

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!

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!

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!

What’s different about commercial air duct cleaning versus residential?

What is the difference between commercial and residential duct cleaning?

Commercial duct systems are significantly larger, more complex, and subjected to heavier contaminant buildup from constant foot traffic and multi-zone HVAC units. Cleaning commercial systems requires industrial-grade extraction gear, specialized duct-access tools, and flexible scheduling to keep business operations running without interruption.

How often should a commercial building have its air ducts cleaned?

How often should a commercial building schedule air duct cleaning?

A comprehensive duct inspection and cleaning every two to three years keeps most commercial systems running smoothly. Facilities with high foot traffic, commercial kitchens, production floors, or recent construction build up contaminants much faster. These high-demand environments benefit from annual service to protect indoor air quality and prevent unnecessary strain on your HVAC system.

How long does commercial air duct cleaning take?

How long does a commercial duct cleaning project take?

Project duration depends directly on your facility’s square footage, the number of air handler units, and system accessibility. We coordinate service windows around your operational schedule, including off-hours and weekends, to ensure the job is completed efficiently without disrupting your team or customers.

How much does commercial air duct cleaning cost?

How much does commercial duct cleaning cost?

Pricing is tailored to your building’s specific layout, total linear footage of ductwork, and the overall complexity of your HVAC system. After reviewing your facility’s requirements, Capitol Duct Cleaning provides transparent, straightforward project estimates with zero hidden fees.

How can I tell if the commercial air duct cleaning worked?

How do you verify that the cleaning was successful?

We verify results by measuring improved airflow and inspecting every serviced line for complete debris removal. Technicians document the entire process with clear before-and-after photos, giving facility managers visual confirmation of a clean, unobstructed ventilation system.
