Our service from start to finish was fabulous! We have just moved in and knew the home had never been cleaned. The two techs were so conscientious and spent about 6 hours cleaning each zone, along with the Dryer vent. Great work, pleasant company to work with from start to finish.

Absolutely the best. As an HVAC contractor I needed a duct blast leakage test done for town approval on an A/C-Heat pump system and ductwork installation. They came highly recommended through trade contacts. Great communication and scheduling. Test was performed by an experienced trade professional without bias or confrontation. I have had my customers use Duct Diag. for duct cleaning and they were just as happy. 100% recommend this company.

⭐️⭐️⭐️⭐️⭐️ Absolutely Amazing! We are beyond impressed with Duct Diagnostics, LLC in Middletown, CT! Eric and Leo came to our home on time and did an absolutely amazing job. They were professional, knowledgeable, thorough, and truly took pride in their work. Unfortunately, last week we hired another company to clean our vents and it was a terrible experience. They left our home dirty, did not do a good job, and, even worse, they used the wrong tool and actually ripped one of our instalation Then we called Duct Diagnostics, LLC, and what a difference! Eric and Leo came prepared with the right tools and equipment and took their time to properly inspect and clean everything. They covered our furniture before work and did an incredible job and left everything clean and professionally done. We are so impressed with this company. This is honestly one of the best companies we have ever worked with. As you can see from the photo Before & After. I highly, highly recommend Duct Diagnostics, LLC! If you want the job done right, this is the company to call! ⭐️⭐️⭐️⭐️⭐️

Great service. They did a great job cleaning everything. They also found some faults that were causing circulation issues and repaired them. Smart, friendly, and knowledgeable. Would definitely use their services again.
