I'm very pleased with Duct Diagnostics. The 3 gentlemen who came out to clean our ductwork (while we're in the middle of a renovation) were professional, courteous and did a fantastic job. They explained every procedure and explained how we can continue maintaining our system safely and effectively. They have my highest recommendation.

We just had our ducts cleaned today and I couldn’t be more impressed with the entire experience. From start to finish, the team was professional, punctual, and extremely thorough.They took the time to explain exactly what they were doing, showed us before-and-after photos, and made sure every vent, return, and the main trunk lines were cleaned properly. You could immediately tell they take pride in their work. They were also incredibly respectful of our home — wearing shoe covers, protecting floors, and cleaning up completely before they left.The difference in air quality is noticeable already. As new homeowners, it gives us real peace of mind knowing the system is clean and running efficiently.If you’re considering duct cleaning, don’t hesitate. This team was honest, efficient, and worth every penny. Five stars all the way!

The team was courteous and professional. They arrived on time and described what needed to be done at our house. They put drop cloths over surfaces where they would working to keep our space clean. Once finished they reviewed their findings. I would certainly use them again and would recommend to anyone. Thanks team!

I called Duck Diagnostics today for an issue I thought I had with my ducts. Tim Called me right back within minutes of my call to them and spent about 15 minutes on the phone with me walking me through the percieved problem. It turns out I had no issues at all with the ductwork. Tim didn't try to make me book an appointment, he just helped me realize that all was fine with my ductwork. I highly recommend Duck Diagnostics!
