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.

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.

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!

I called Duck Diagnostics today for an issue I thought I had with my ducts. Tim Called me right back within minutes of my call to them and spent about 15 minutes on the phone with me walking me through the percieved problem. It turns out I had no issues at all with the ductwork. Tim didn't try to make me book an appointment, he just helped me realize that all was fine with my ductwork. I highly recommend Duck Diagnostics!

The crew, Bobby and John, did a meticulously thorough and clean job. Both were most courteous and pleasant individuals. It really showed they knew what they were doing.
The company, Duct Diagnostic , LLC, was highly recommended by our AC company and we’re are very pleased with the outcome.

They are expensive, but worth it.
Highly recommended.
Dan and Ryan were terrific. They were on time (early!), thorough and extremely neat and efficient. Everything was put back exactly as they found it with no traces of cleaning or mess.

The team at Duct Diagnostics did an excellent job servicing my two HVAC units. The entire team from start to finish was super friendly, and answered all my questions regarding the process in which they would clean the vents.

The whole process took about 6 hours, in which they thoroughly cleaned the vents, the HVAC returns, and even the grates themselves on the floor and ceiling. The team provided before and after photos, and I was shocked at both how dirty the vents were, and how well they looked after the job was done

After the team was finished, I immediately noticed that the air was cleaner and fresher. I would absolutely use Duct Diagnostics again!

Bob and John were 100% professional, engaging, and informative.

They explained all that was going to be completed from set up, protection to clean up.

When the job was completed all was cleaned and back in place. As if there was ZERO disruption.

This was my first experience with duct cleaning so I had no idea what to expect. Vincent and Kevin handled everything, including my questions and nosy dog, very professionally. The weather on the day of the service was heavy rain and wind all day but they covered up the floors so that there was no mess anywhere in the house. It was a very nice experience and a relief to know that everything is clean.

The 3 man cleaning crew was knowledgeable, courteous and professional.
Wherever the worked they cleaned up after themselves
I thought the $2,850 price was excessive but I have nothing to compare it to
I need to wait a week before I can judge the effectiveness of the cleaning
I was shown pictures of the duct interior and they appear cleaner

I recommend Duct Diagnostics. I run a heating and air-conditioning company and refer all of our customers over to Ralph and Tim at Duct Diagnostics. I’ve worked with these guys on commercial duct cleaning projects, as well as residential duct cleaning projects. All of their team members from the sales staff to the field employees are great.
We are very pleased!
