Our team of experienced professionals is here to tackle any air duct cleaning project, no matter the size or urgency, so you can breathe easier in your own home.
Over time, your air ducts can collect a wide array of unsavory contaminants such as dust, mold, debris, and other harmful substances. Since the ducts are the component responsible for distributing air throughout your home, that air can become dirtier and more difficult to breathe as they gather more and more debris.
Your ducts often run through some pretty unpleasant places. The attics, crawlspaces, and interior walls they travel through are rife with dust, dander, pollen, and bacteria that you don’t want circulating your home. Neither your supply ducts, which deliver air throughout your home, nor the return ducts that bring it back to the air handling unit are exempt from contamination. Professional air duct cleaning helps negate this, keeping things breathable.
Cleaner Ducts Mean Cleaner Air
We show up when we say we will, treat your home with care, and always come ready to work.
Your technician will take the time to show you your ductwork before and after our cleaning services so that you can see the difference professional service makes.
We use a method called Source Removal, which works by creating negative pressure in your system. It acts like a high-powered vacuum, pulling dust, debris, and other buildup straight out of your ducts.
Our crew shows up on time, respects your space, and gets to work with a professional attitude. We use industry-standard equipment and a straightforward approach, so your clean air comes safely and with ease.
Reviews
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.
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.
I highly recommend Capitol Duct Cleaning, especially if you’re lucky enough to get Larry and Q. Outstanding service from start to finish!
I highly recommend this company!

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!
Improved Air Quality is One of the Biggest Reasons Homeowners Choose to Have Their Air Ducts Cleaned
As your HVAC system runs, dust, dirt, and other debris collect inside your ductwork over time. That buildup makes it harder for air to flow freely, which in turn makes the system work longer to move heated or cooled air throughout your space.
The more your system struggles to push air through, the longer it takes to reach a comfortable temperature. This might not seem like a big issue at first, but it adds up. A clogged system uses more energy, which means higher utility bills. It also adds extra strain on your equipment, which can both wear out parts faster and shorten the lifespan of your HVAC system.
Whether you deal with allergies, asthma, or other conditions that make air quality a bigger concern, or have family members who do, good air quality is more than a luxury. In these cases, keeping the home environment as clean and breathable as possible becomes a priority.
Professional air duct cleaning can help by removing built-up contaminants like dust, pet dander, pollen, and bacteria that circulate through your system. By clearing out these particles, duct cleaning supports healthier indoor air and helps create a more comfortable space for everyone in the home.
Our Process:
Simple, Straightforward, & Right To the Point
Most of our air duct cleaning process can be broken down into four easy steps.
Specialized Connection
We start by connecting our high-powered duct vacuum to your system, usually near the furnace.
1.
This isn’t your average vacuum. It’s a professional-grade tool designed specifically for air duct cleaning.HIGH PRESSURE VACUUM
Once connected, we power up the system.
2.
Using compressed air, the vacuum pulls loose dust and debris straight out of your ductwork.FULL SYSTEM CLEANSE
Next, we feed a cleaning tool through the ducts to dislodge tougher buildup stuck to the inner walls.
3.RESEAL & RETURN
When the cleaning is complete, we reseal the access points and put everything back the way we found it. Your system is left clean, closed, and ready to go.

- My house is kept very clean – do I really need air duct cleaning?
How often should I have my home’s air ducts cleaned?
Experts generally recommend a thorough air duct cleaning every 3 to 5 years under normal conditions. Homes in Western Washington with pets, smokers, or residents with allergies or asthma may require more frequent cleanings (every 2–3 years).
How do I know if my ductwork needs cleaning?
Look for common warning signs that it’s time for cleaning. Musty or dusty odors coming from vents, unusually dirty vent covers, or visible mold growth inside ducts are all red flags.
What are the benefits of air duct cleaning?
Cleaning your air ducts can significantly improve indoor air quality and overall home cleanliness. By removing dust, pollen, pet dander, and other debris, it helps reduce allergens in the air, which is especially beneficial for individuals with asthma or allergies.
How is professional air duct cleaning performed?
Professional duct cleaners use specialized equipment to dislodge and remove dust from the ducts. They typically seal off your duct system and connect a powerful vacuum to create negative pressure. Then, they use tools like rotary brushes or air whips to agitate the inside of the ducts, loosening debris while the vacuum removes it safely.
My house is kept very clean – do I really need air duct cleaning?
Even in a clean home, your HVAC ducts will accumulate dust and pollutants over time. Routine cleaning (vacuuming, dusting) cannot reach inside the ducts, and vacuuming can stir up fine dust that standard vacuums can’t trap, which then settles in the ducts.
