THE IMPORTANCE OF INDOOR AIR QUALITY
“Indoor air quality” refers to the quality of the air indoors. On average, we spend 90% of our time indoors where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations.*

I 100% recommend these guys to anyone in the local area.
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.

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!

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







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!
