Air Duct Cleaning Services in Vernon, CT

We contacted Duct Diagnostics due to a strong obnoxious odor coming from our HVAC system, which we thought could have been caused by dirty ductwork. We had a free live video consultation with Ralph during which he diagnosed the potential problem as NOT being dirty ducts. He gage us tips and suggestions as to what may be causing the odor which will be simple to implement at no cost to us. He told us that yes, they could come clean the ducts but that that would likely not solve the issue. He said that he would not want us to spend that money. We have to give Ralph the highest marks for integrity and technical expertise - he could have very easily taken advantage of us and talked us into a very expensive duct , but he cleaning job, but he did not do so. We cannot recommend Duct Diagnostics enough! They are straight shooters!

We just bought an old house, on one floor with 3000 square feet of crawl space. Duct Diagnostics did an unbelievably thorough and complete job of cleaning the large amount of duct work that had probably never been cleaned before. They were meticulous in their cleanup, courteous and worked very well together as a team. The vents and baseboards look better than they did when they started. I cannot recommend them highly enough.

Eric & Anthony did a fantastic job. They covered EVERYTHING and were extremely respectful, neat and friendly. I would highly recommend them.

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.

Professional, courteous and neat. Dan and Anthony were terrific.

Lou and Anthony were Amazing - so helpful, very informative and professional! Left my house smelling good and clean!

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! ⭐️⭐️⭐️⭐️⭐️
