In 2020 we had Daves Ducts come clean our ducts because we thought it might help with some musty smell we were having. We weren't sure it was necessary, but when we first spoke on the phone, they mentioned they would not proceed unless there was actually something to clean. Turns out the ducts had been clean only a few years prior and they were totally fine. They should have taken one look and told us this was not necessary.
We were promised before and after photos of every register. These were not provided, and I had to follow up several times. Ultimately we were given 10 unlabelled 'after' photos. I asked why only 10 - no answer.
The team was a little disruptive in the house and not particularly sensitive to us - very transactional.
After all was said and done, it was pretty clear that this was just a blow-and-go cash-in, but we were really looking for someone to help us figure out if this was an opportunity to fix a weird smell.
