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!

Quintin, a superb technician from Capitol Duct Cleaning arrived on time. He was very professional, explained what he will be doing and allowed quality time for questions. He was thorough, respectful of our home and took time to go over the work he did at the end providing photos for verification of the work he performed. Next time I need service, I will definitely call on Capitol Duct Cleaning and request Quintin to do the job again. Thank you again!

Was really impressed with capital duct. My ducts were really leaky and after the guys were done doing the aerosealthe leakage was reduced down to 10sq inches. The guys were clean, timely and professional and talked me through the entire process. I would definitely recommend this company to my friends and family. And will have them come back next year to do my duct cleaning.

Reece and Lucas showed up on time, did a walk through and worked efficiently and professionally to get the multitude of ducts cleaned and sanitized in our 3000 plus square foot home. They took before and after photos, taking the time to explain things we can do to improve the air quality of our home. I was very impressed with these two gentlemen. The office staff that I worked with we very responsive to our urgent need to get this cleaning accomplished. I would highly recommend them to potential Clints.

Matt was the best!!!
He came to my home, inspected it and kindly removed a dead possum that was underneath my house that had ripped up the duct work which he then repaired nicely.
He is kind and professional and I would refer him and Capital Duct to anyone in need of their services.
Thank you again, Matt!!!

Capitol Duct Cleaning was able to come out same day and clean the dryer vent of our newly purchased home. Brett, the technician, did a thorough job cleaning out the ducting and then went the extra mile to troubleshoot why the dryer was not pumping out much air through the clean duct. He even inspected our crawl space! I highly recommend Capitol, and especially Brett! I would use them again! And I will!

Today I had my ducts cleaned. First time for me, so I was apprehensive about all that's involved. I expressed my concerns to Amy at the office, she sent Brett, a seasoned technician. Both Amy and Brett are to be commended for their professionalism, friendliness and understanding. Our house it's a fairly good size and in less then 3 hours he was done including the dryer. Brett showed us picture of before and after and the difference was amazing. I recommend Capitol Duct cleaning
My husband and I are totally satisfied.
