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! ⭐️⭐️⭐️⭐️⭐️

Very quick and efficient estimate for duct cleaning via FaceTime. Eric and Leo were great. Both were super courteous and very efficient. Eric took time to share his thoughts on some issues we pointed out before he started, which he resolved. Very good experience today.
