Air Duct Cleaning Services in New London, CT

Dan and Anthony came to the house to do the job. They were very neat and conscientious as they did their work. They shared before and after photos, which were very helpful. Very happy with this group.

Great experience from first phone call all the way through to the final day of the job. Rob was able to provide an estimate based on the FaceTime walkthrough we did of the entire house - including the attic and basement. He was knowledgeable, thorough, open and forthcoming every step of the way. We scheduled the job for a few months out bc of the crazy winter we had and when I had to reschedule at the last minute bc of a travel conflict DD was more than accommodating. The crew was punctual, if not early, clean and respectful. Kevin and Andrew were excellent and efficient. Both extremely knowledgeable and easy to work with. Highly recommend.

Very efficient and thorough. They did an excellent job.

Eric and John were very courteous and helpful. They did the work in a timely fashion. We would certainly use them in the future!

Dan and Anthony were FABULOUS! Explained everything they were doing in great detail. Left the house cleaner than it was before they arrived! Great company to work with from first phone call to job completion. Wish all companies could be so great to work with! THANK YOU!!!

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.
