My house was getting so dusty in the matter of hours after cleaning, I decided that the ducts/vents were to blame (my husband disagreed at the time). I spoke to the owner on the phone, she was extremely nice and accommodating to our crazy work schedule. The team of 2 guys arrived on time, almost to the minute! Over the course of 3 hours, they worked in tandem vacuuming the ducts, cleaning the furnace and registers. The house immediately had a fresh smell!!! My husband was very impressed and asked them to clean the dryer vent for an extra charge. it was amazing to see how much lint was trapped in the line to the outside of the house! I can tell you that I now only have to dust once every 2 weeks!
