I was referred to Duct Doctor by a neighbor so I decided to use them to clean the ducts in my almost 50 year old house. The ducts had never been cleaned before so I figured that it needed to be done – especially since we had just had some renovations done which created a lot of dust in the house. Hector and Alex did a great job! They were very pleasant and did a thorough cleaning on all the ducts. As intensive as it is, they were done in a fairly short time – it only took a few hours. I felt like they did a really good job cleaning – it wasn’t just shove a shop vac in the vents like a lot of other places do. I would highly recommend Duct Doctor for any duct cleaning needs.
