Thank you for sending Brett, Dominic, Joey, Lucas, and Matt!!

Had a couple days of crawl space work done on both my home and my rental. All of the young men who worked here were very polite and professional. They were quite pleasant, communicated clearly, hard-working and teamed together very well. Appears they enjoy what theyre doing! Both households are looking forward to enjoying improved efficiency and I happily look forward to recommending Capital Duct Cleaning to everyone I know!

After 6 yrs after painting my house Joey found that my vent had been painted shut and my dryer duct was disconnected. He took the time to get into the crawl space (which is more a low crawl space) to reconnect it! This will surely make my wife happy moving forward! Thanks Joey.

Brett and Quinton were prompt and professional. They answered our questions, explained their protocol and did a very thorough cleaning of 2 airhandlers and many ducts. They also did a great job cleaning our very dirty dryer duct. We highly recommend Capitol Duct Cleaning.

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!

Brett B is an excellent technician. He is professional and did a great job inspecting and cleaning my dryer duct. On a previous job he built me a custom dryer duct. It works perfectly and makes inspection and cleaning quick and easy. I recommend him for all my duct work. He is easy to communicate with and gets the job done. Capitol duct cleaning is the one to go to for all duct work.

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.

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!
