I have to update my review as we have learned that we have a mouse in our house and the only thing to change is this service. When they got here I specifically asked about our door staying open for the whole service as no one is here to sit and watch to see if something would try and enter my home. They said the loud noise of the machine should not be inviting for pests. Well he was wrong. Now I have to pay for another service to get rid of this new problem as a result of poor service received from this company.
This is the first time I've ever had my ducts cleaned so wasn't sure what too expect other than what I read and saw in videos. So when they showed up they were focused and not too friendly but that was ok as long as they did a great job. One thing that really annoyed me was that they cut through my duct work as it had never been done before but when they went to fix it they left a mess behind. All the small pieces of metal that was cut and other garbage which I didn't notice till afterward because I stepped on two pieces (:$) that got stuck in my foot. Considering it's sharp metal it was pretty annoying and disappointing.
As for the actual cleaning process who knows if my air quality feels any better. I did see all the stuff they pulled out of the dryer vent which was gross but again. He ended up cleaning it by just blowing it off our patio section into our grass.
Wouldn't use them again.
