Your Trusted Air Duct Cleaners

Capitol Duct Cleaning has proudly offered quality air duct cleaning services to businesses throughout Washington for over 25 years and we are proud of the relationships we have built within our communities.

Our commercial clients continue to utilize our team time and time again. Commercial air duct cleaning removes harmful contaminants, debris, dust, and other materials from your HVAC system. These substances can build up in the ductwork of your business over time — especially for businesses that see heavy foot traffic from employees and customers.  Like anything in your business, if it’s left uncleaned for long enough, grime can build up over time.

Some businesses choose to try and clean their air ducts themselves, but often with little success. It can be extremely difficult to gain access to the area of your air ducts that need to be cleaned the most. Our team utilizes cutting-edge industry technology to thoroughly clean the entire length of your air ducts. Air duct cleaning allows your HVAC system to operate at maximum efficiency, which in turn saves you money, reduces your footprint, and increases the indoor air quality of your business!




At Capitol Duct Cleaning, we aim to give you the same level of customer service that we know you provide your customers and clients. We understand that no job is complete until you are completely satisfied with our commercial duct cleaning work.

If you for whatever reason are not satisfied with the work we’ve done, please let us know and we will remedy the situation in a timely and effective manner. With Capitol Duct Cleaning in Olympia, you can rest easy knowing that you are going to get the comprehensive commercial duct cleaning services you paid for.

Practically anything that winds up in your business’ ducts can be removed.

Common materials that are removed from ductwork during commercial air duct cleaning can include bacteria, dust particles, dust mites, pet dander, skin dander, pollen, and lint.

Our cleaning methods are excellent
for keeping HVAC systems clean, clear,
and healthier than ever.

With all these harmful materials removed, you’ll breathe easier and your clients and employees will enjoy fresher, cleaner air.  You will also see the strong results of your heating and cooling bills going down.  

With maximized efficiency of your HVAC system, you’ll experience lower energy consumption and reduced energy bills.  This also improves the lifespan of your system as regular air duct cleaning is an important part of HVAC maintenance.
