The technician was on time and polite. He was professional and did a good job. He asked to bring the hosing into the house one way and instead accommodated my wifes request and did it differently. The scheduler answered all of our questions and was quite helpful. We highly recommend this company.

Brett and his colleague did a fantastic job taking care of my dryer vent line. They even took care of an issue at the end of my vent line on the roof I had not been aware of for almost 20 years! Capitol Duct Cleaning was wonderful to work with and had excellent customer service. I will never go back to the other company I used in the Lacey area.

Communication was super clear. Multiple texts and emails were sent a few days leading up with reminders of the appointment time and directions to make everything go smooth. When the tech was on their way, I got a link to track the location to know exactly when they would arrive, which was really great. Technician was nice and easy to talk to. Service was done thoroughly and very quickly.

Our technician Rusty did an amazing job, went above an beyond to get the job done. We where way over due for a cleaning.

Also, We have an external HVAC system (an all in-one unit) which I guess needs to be set up differently. He found away to make it work!

You can already tell the difference in the air quality!!
Thank you Randy!
