Air Duct Cleaning Services in Monroe, CT

We had not had our air ducts cleaned at all. My HVAC company recommended Duct Diagnostics. And I am mighty glad they did. The three-person team of Duct Diagnostics, led by Eric did a fantastic job. They came in at 7:30 am and left around 4 pm. They did a thorough job and cleaned up the work areas before they left. I would highly recommend Duct Diagnostics for your duct cleaning needs.

Duct Diagnostics did an amazing job cleaning our HVAC! We recently bought a home and could tell the ducts needed major work. Actually, when the team came to evaluate our system, they said it looked like the HVAC had never been cleaned since the house was built in 1993. Josh and Gibson were extremely professional, personable, and transparent with costs and services. They showed detailed pictures at the start and end, always confirmed with us before starting an unexpected part of the cleaning, and kept our house spotless throughout. The entire cleaning was done in 4 hours - well ahead of schedule without compromising the quality. We will absolutely be booking with this company in the future and will be recommending to others in need of their service!

Loved these guys. Very friendly. Hard workers . Even came early😁. I recommended you to my neighbor in 18 Salem walk, she inquired after seeing your van. Thanks!

Duct Diagnostics did an excellent job on cleaning the furance and all the duct work. There were 6 people here in the morning and 3 in the afternoon that did a great job of removing the direct and cleaning our system. Thank you and your team very much and look forward to using Duct Diagnostics again.

Andrew, Kevin’s,Dan, and Taryl did a fantastic job. I will be using them again. Highly recommend. Thank you.

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.

Vincent & Ryan were incredible!! Service was immaculate & thoroughly completed!! Great experience! Highly recommend

The owner is professional and easy to work with. The technicians Dan and John were also professional, competent and friendly.

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!
