We had Capitol Duct Cleaning out to our home to insulate both the attic and crawl space. Not only was the team on time and professional, but they did the job clean and efficiently. If you're looking for a business who will do an excellent job taking care of your home, look no further. I highly recommend them!

The folks at Capitol Duct Cleaning provided excellent service. I was able to talk through possible issues I was experiencing with the appointment specialist and the appointment was scheduled to take place within a few days. The technician informed me of his expected arrival time. When he arrived he was friendly, professional, and very knowledgeable. I would definitely recommend their services. Thanks, from a satisfied customer.

I used to coordinate customer service classes. This company EXCEEDS my highest expectations!
They return calls very timely. They have an "after hours" message service. Scheduling is effortless.
They send updates when the tech is on the way...you even are given a tracking app to see how far away the tech is in your scheduled day/time. AND their pricing is reasonable and technicians are professional. I can't say enough good things about CAPITOL DUCT

Got a quote from Coit for $650, Capitol Duct Cleaning came in at less than half that for our small home. The tech, Chuck was prepared, knowledgeable and a very nice guy. Winona in the office was great to deal with. She even called to remind us of the appointment and checked for questions and concerns. I will recommend these guys all day long!
